ISO 16304

• Abstract:

  This document provides a method for addressing ship generated waste and cargo residues from when they are offloaded from the ship, to how they are managed ashore. The provision, operation and use of port reception facilities (PRFs) are inherently linked, so this document addresses the design of PRFs, and their operation and management. This document is designed to be used by ports and terminals with existing PRFs which aim to refine their systems; it can also be used by new ports and terminals that are developing PRFs. Parties to MARPOL are obligated as Port States to ensure that port reception facilities (PRFs) adequate to meet the needs of the ships using them without causing undue delay are provided at their ports and terminals. MARPOL does not seek to regulate the management of ship generated waste and cargo residues at ports and terminals beyond the reception facility requirement. However, ports and terminals may need to consider national, regional and local regulations. While these regulations can exceed the scope of MARPOL, the IMO recognises the need to manage ship generated waste and cargo residues at ports and terminals as part of an environmentally sound management approach for avoiding, minimising, and eliminating pollution from ships. In consideration of above, this document applies to the management of ship generated waste and cargo residues regulated by MARPOL that are discharged at ports and terminals. It also covers principles and issues that should be considered in the development of a PWMP, its implementation and PRF operations. The operation of any PRF is governed by the principles and procedures included in the PWMP. The procedures to operate the PRF and the development of a PWMP are closely linked and therefore are integrated into this document. This document addresses the principles and issues that should be considered in: — The development of a port waste management strategy; — The design and operation of PRF; — PWMP development, implementation and compliance; and — PRF management and accountability. This document has been designed to be used by ports and terminals of any size. It does not give specifics on the size or location of a PRF in each port, but provides a list of principles to be considered and applied to any size of type of port or terminal (e.g. marina, fishing port, container terminal, oil terminal, roll on/roll off terminal, cruise terminal, ferry terminal, bulk or general cargo terminal, ship repair or recycling facility, and offshore terminal). Inland ports and marinas and those ports that have entered regional arrangements for the provision of a PRF can also use this document.

Overview

ISO 16304: Ships and Marine Technology - Arrangement and Management of Port Waste Reception Facilities is an international standard developed by ISO focusing on marine environment protection. The document offers a structured method for addressing ship-generated waste and cargo residues after they are offloaded from vessels and details how these are managed ashore. With emphasis on the provision, operation, use, and management of port reception facilities (PRFs), ISO 16304 is an essential resource for ports, terminals, and stakeholders seeking to refine current waste management systems and develop new PRFs. The standard is applicable globally and supports compliance with MARPOL requirements, helping ports ensure environmental safety, regulatory compliance, and operational efficiency.

Key Topics

• Port Waste Management Strategy: Guidance on developing comprehensive strategies that consider administrative, legal, technical, and infrastructure perspectives is provided. The standard stresses the integration of national, regional, and local regulations, which often go beyond international requirements such as MARPOL.

• Design and Operation of PRFs: ISO 16304 covers both the physical design and daily operations of PRFs, including consideration for port and vessel types, service provider accountability, and anticipated waste volumes. Emphasis is placed on ensuring facilities do not cause undue delay or disincentivize use.

• Port Waste Management Plan (PWMP): The document outlines the development, implementation, and compliance of a PWMP, detailing responsibilities, cost recovery systems, data collection, and stakeholder engagement to ensure efficient and environmentally sound waste management.

• Facility Management and Accountability: Principle-driven recommendations ensure that PRF operations align with best practices for sustainability, traceability, and regulatory obligations.

• Waste Streams and Minimization: ISO 16304 recognizes the diversity of waste types-such as cargo residues, hazardous and medical waste, and quarantine waste-and provides principles for hierarchy in handling, favoring prevention, reduction, reuse, and recycling over disposal.

Applications

ISO 16304 is designed for a broad range of users in the maritime and port sectors:

• Existing Ports and Terminals: Organizations seeking to refine or upgrade their waste management systems can use the standard as a benchmarking and guidance tool to enhance compliance, efficiency, and environmental outcomes.

• New Port and Terminal Development: The standard offers foundational principles adaptable to any type or size of facility, supporting the planning and construction of compliant PRFs from the outset.

• Diverse Port Types: Whether operating marinas, fishing ports, container terminals, cruise, bulk cargo, oil terminals, ferry terminals, ship repair or recycling facilities, or offshore terminals, organizations can apply ISO 16304 principles effectively.

• Inland Ports and Marinas: The guidance extends to non-coastal facilities and supports those in regional agreements for shared reception facilities.

• Regulatory Authorities and Port States: By aligning with MARPOL obligations, ISO 16304 helps Port States fulfill their international commitments, ensuring provision of adequate PRFs without undue delay to ships.

Related Standards

• MARPOL (International Convention for the Prevention of Pollution from Ships): The key international framework regulating ship-generated waste. ISO 16304 is developed in close alignment with MARPOL requirements for PRFs.

• ISO 21070: Shipboard Waste Management: Provides complementary guidelines for the segregation and minimization of waste on board ships, facilitating more effective PRF operations ashore.

• ISO 24146-2: Inland Port Waste Reception: For reference in managing waste from vessels operating in inland waterways.

Practical Value

Implementing ISO 16304 helps stakeholders:

• Optimize waste management practices for regulatory compliance and environmental protection.
• Design PRFs that are flexible, efficient, and suited to the demands of diverse port operations.
• Harmonize procedures and documentation with international best practices, improving transparency and accountability.
• Facilitate port and terminal accreditation with global shipping and maritime authorities by demonstrating adherence to recognized standards.
• Reduce operational costs by improving efficiency and enabling participation in recycling and waste minimization programs.

By following ISO 16304, ports and marine industry stakeholders ensure they are equipped to meet current and future challenges in marine environment protection and port waste management.

Introduction
The development of adequate port waste reception facilities (PRFs) for ship-generated waste and cargo
residues is a major factor in the management of each of the shipboard waste streams covered by the
[1]
International Convention for the Prevention of Pollution from Ships (MARPOL ) Annexes I to VI, as amended,
[1]
excluding Annex III (packaged dangerous goods). MARPOL requires the Parties to ensure the provision
[1]
of adequate reception facilities in ports to receive these wastes. The Parties to MARPOL are required
to implement legislation to provide for PRFs. Regional and intergovernmental legislation has also been
developed. However, due to operational, ownership, geographic and legislative differences in ports, there is
a large disparity in how operations are conducted. To overcome some of the major issues, the International
Maritime Organization (IMO), through its Sub-Committee on Implementation of IMO Instruments (III)
[formerly the Sub-Committee on Flag State Implementation (FSI)] developed an action programme to tackle
the inadequacy of PRFs. Then, IMO adopted MEPC.83(44) Guidelines for Ensuring the Adequacy of Port Waste
[4]
Reception Facilities.
To obtain the most efficient management of waste and to reduce the time and resource burden in segregating
and handling waste in the ports, the concept of waste minimization has been integrated into this document
by incorporating the following principles:
— for waste generated aboard a ship:
“Prevention before recycling, before energy recovery, before disposal.”
— once the waste is offloaded ashore:
“Avoidance before reduction, before reuse, before recycling, before incineration with energy recovery,
before disposal”.
Ship owners and operators, cargo owners, and port and terminal owners and operators, along with
governments are aware of the importance of well-organized and managed waste collection, especially with
respect to health and safety on board ships and at ports and terminals. It has been acknowledged within
the IMO that standardized methodologies for waste management both on board ships and ashore at PRFs
would harmonize practices and ensure a smooth delivery of ship-generated waste and cargo residues to
[5]
shore-side facilities. ISO 21070 provides a methodology for ships to segregate their garbage, thus, port
waste reception facilities worldwide can expect a certain level of ship segregated waste and cargo residues.
[5]
However, ISO 21070 cannot work alone and requires a parallel International Standard that covers the
reception of ship-generated waste. This document assists in the planning for the provision of adequate PRFs.
[1]
Parties to MARPOL are obligated as Port States to ensure that port waste reception facilities (PRFs)
adequate to meet the needs of the ships using them without causing undue delay are provided at their ports
[1]
and terminals. MARPOL does not seek to regulate the management of ship-generated waste and cargo
residues at ports and terminals beyond the reception facility requirement. The IMO recognizes the need
to manage ship-generated waste and cargo residues at ports and terminals as part of an environmentally
sound management approach for avoiding, minimizing and eliminating pollution from ships.
In consideration of the above, this document applies to the management of ship-generated waste and cargo
[1]
residues regulated by MARPOL that are discharged at ports and terminals. It also covers principles and
issues that are expected to be considered in the development of a Port Waste Management Plan (PWMP), its
implementation and PRF operations. The operation of any PRF is governed by the principles and procedures
included in the PWMP. The procedures to operate the PRF and the development of a PWMP are closely linked
and therefore integrated into this document.

This document provides requirements and guidance on the provision, arrangement, operation, management,
use and design of port waste reception facilities (PRFs). In doing so, it provides a method for addressing
ship-generated waste, cargo residues and operational residues at ports when the waste and residues are
offloaded from the ship.
This document addresses principles and issues on:
— the development of a port waste management strategy;
— the design and operation of PRF;
— PWMP development, implementation and compliance; and
— PRF management and accountability.
This document is designed to be used by ports and terminals with existing PRFs that aim to refine their
systems. It can also be used by new ports and terminals that are developing PRFs. This document has been
designed to be used by ports and terminals of any size. It does not give specifics on the size or location of a
PRF in each port, but provides a list of principles to be considered and applied to any size of type of port or
terminal (e.g. marina, fishing port, container terminal, oil terminal, roll on/roll off terminal, cruise terminal,
ferry terminal, bulk or general cargo terminal, ship repair or recycling facility, and offshore terminal).

4 Waste management strategy elements
4.1 General
There are three main components of waste management strategies:
— administrative and legal matters (4.2);
— technology (4.3); and
— infrastructure and support services (4.4).
4.2 Administrative and legal matters
Many states have implemented legislation, policies and national waste management strategies that govern
the management of waste received at PRFs. Such legislation should be considered when developing a port
waste management strategy, as it will assist in determining how local compliance can affect the operation of
PRFs within a port. Additionally, there can be a need for either licensing or local approvals, or both, and the
port or terminal operator should consider waste tracking and documentation.
The best possible environmental solution for waste recovery and disposal should be identified. Waste
management targets adopted by the national administration for ports and terminals within its jurisdiction
can be considered in the development of port waste management strategies. If there are no such targets,
then the port or terminal operator can consider developing them.

ISO/FDIS 16304:2026(en)
4.3 Technology
PRFs should use waste management technology that is current and applicable for ship-generated waste
and cargo residues expected from ships using the port or terminal. Recycling and reclamation of waste is
preferable to disposal (see 6.5). Therefore, any waste management strategy should recognize and promote
alternative methods of waste management that utilize new and emerging technologies.
4.4 Infrastructure and support services
The waste management strategy should be developed with an awareness of the infrastructure and support
services not only throughout the port or terminal, but also beyond those physical limits. Suitable waste
transport logistics, recycling facilities, treatment facilities, and if necessary, final disposal sites shall be
in place. These treatment and disposal facilities are located within the port or outside the port. Waste
management strategies should also incorporate proactive mechanisms to inform and educate those having
an interest in using the PRF.
5 Design and operation of PRFs
5.1 General
The types and number of ships normally calling at the port or terminal and the nature of operations
should be considered in the planning for the provision of a PRF. PRFs for relevant wastes shall be available
without causing undue delay to ships or imposing economic or other disincentives for their use. The port
waste management plan (PWMP) provides options for waste collection and handling. The calculated PRF
capacity and the design of the PRF provide a foundation for the PWMP. However, for those waste volumes
that can be anticipated to fluctuate widely over different periods, the provision of a PRF should be adapted
appropriately. The system designed to support and operate a PRF should consider the core components as
indicated through 5.2 to 5.7.
5.2 Port characteristics
5.2.1 Spatial and siting requirements
The location of a PRF should be “convenient” and not create a disincentive for ships to use. The location
shall be suitable and sufficient to allow easy and safe use that does not impose an undue delay upon the
ship. Siting considerations should include an awareness of the impact on other port operations as well as the
public areas surrounding the port or terminal.
Larger ports and terminals require higher capacities or more diverse capabilities. Construction of a new
port or terminal may offer greater flexibility in design as opposed to making improvements to an existing
PRF.
Regardless of the type of PRF that is chosen, the port or terminal geography and layout should be considered
as part of the design phase. The best way to collect each waste stream throughout the port or at the terminal
shall be determined. In a compact port with large berths, garbage waste disposal bins on each quay or a
direct transfer to the waste handler can be implemented. However, in other port configurations, it can be
better to collect waste by barge. If the port is lock-bound, waste can be landed upon entry or exit to the lock.
A port or terminal that is planning to increase operations in the future can see a rise in shipping waste
volumes. This can result in a need of additional PRF capability during planning activities.
5.2.2 Types of cargo handled within the port or by the terminal
[1]
Multiple MARPOL waste reception facilities can be required. Ports or terminals that receive ships with
diverse cargoes that can produce cargo residues, oily waste, and noxious liquid substance wash water can
create unique waste handling challenges.

ISO/FDIS 16304:2026(en)
5.2.3 PRF service providers
Companies that are licensed or otherwise certified or approved to provide waste handling services should
be identified and verified by the port administration or port authority. Effective port waste management
goes beyond the act of receiving waste from ships. Good downstream waste management supports the
intent and purpose of having a PRF.
5.2.4 External factors
Extreme weather conditions or extreme tidal cycles can make it difficult to access PRF services or hinder the
operation of traditional waste handling equipment.
5.3 Types
5.3.1 General
The type of PRF can vary between ports and terminals and is determined after assessing the needs of users
and the frequency of use.
5.3.2 Floating
The use of barges can have distinct advantages, as they are relatively mobile, typically have sufficient
capacity to service multiple ships, and can receive most wastes. Their shallow draught allows for access in
most port and terminal areas. However, sea state limitations can prevent floating reception facilities from
operating at all times. Additionally, there is an added element of risk when transferring waste to a floating
PRF, especially oily or noxious liquid mixtures, or in ports and terminals where ship traffic is heavy and
continuous in volume.
5.3.3 Mobile
Vehicle-borne PRFs offer speed and flexibility, particularly with respect to smaller ports, terminals or
marinas, as a number of ships can be serviced before the vehicle is full. However, the capacity of vehicles,
such as tank trucks and traditional garbage collection trucks can be a limiting factor when servicing large
ships. This can cause delays and increase congestion in ports and terminals. Furthermore, certain areas can
be off limits to third-party waste collection organizations due to either safety or security concerns, or both.
Also, the size of the vehicle can prohibit access to all areas of the port or terminal.
5.3.4 Temporary PRFs
Another possible option is temporary placement of containers or collection bins that are dropped off via
truck and picked up at a later date after the container/bin is full.
5.4 Waste characteristics
5.4.1 General
All types of ship-generated waste and cargo residues that will be received and handled at the port or
terminal shall be identified. Failure to consider certain waste streams can limit the services that the port
or terminal is able to provide. Wastes are offloaded by ships in many different forms, from single waste
streams such as oil, sewage or segregated waste, to mixed waste streams such as garbage. Annex A provides
further information on types of ship-generated waste and cargo residues, as well as a list of waste streams
and treatment options.
5.4.2 Other considerations
Not all waste streams are necessarily produced by every ship or offloaded in every port. Additionally, in
some circumstances it can be necessary or desirable for ships to offload waste, such as food waste and
[1]
cargo residues that can be discharged into the sea under the provisions of MARPOL but due to operations,

ISO/FDIS 16304:2026(en)
company policy, or other considerations, the master of the ship chooses to offload these wastes ashore.
Therefore, the PWMP should consider the following:
a) Some ports or terminals require ships to offload all, or part of, their waste prior to departure.
b) Some port or terminals treat waste from ships on international voyages differently than waste from
ships on domestic voyages (such waste can include quarantine waste, international catering waste or
food waste from galley operations).
c) Ship-generated waste and cargo residues can include hazardous waste or other wastes determined to
be harmful to the marine environment.
5.5 Design capacity
5.5.1 General
The design of a PRF should be based on the number and types of ships calling on the port. The basic PRF
capacity needed in the port or terminal, per waste stream or per ship type, can be calculated based on the
expected or most probable level of traffic in the port.
5.5.2 Existing ports
For existing ports and terminals, the level/quantities of waste received in previous years can be used
to determine PRF capacity. Additionally, if there is any anticipated change in traffic, regulation or waste
management technology, then it can be necessary to modify the initial figures.
5.5.3 New ports or terminals
When designing a new port or terminal or redesigning an existing port to handle new business, or larger or
different types of ships, a calculation of waste reception facility capacity shall be made using estimates of
the expected ship traffic. Calculations should take into consideration the number and frequency of port calls
for each type of ship and the expected wastes that are generated aboard and delivered ashore based on:
— the type and size of ship;
— cargo(es) handled (volumes or tonnes);
— the crew size, the number of passengers (if any);
— the average length of voyages for inbound ships; and
— whether the port is a loading or unloading port or a combination of both.
If no data are available for a new port, the information can be obtained from other ports with similar traffic.
1) [5]
NOTE ISO 21070:—, Annex A provides information on calculation of the expected amounts of waste.
5.6 Waste handling capabilities
5.6.1 Adequacy
A fundamental consideration is to determine the waste handling capabilities needed in order to meet the
definition of adequacy.
1) Under preparation. Stage at the time of publication ISO/FDIS 21070:2026.

ISO/FDIS 16304:2026(en)
5.6.2 Accessibility and suitability
Suitable PRFs for all waste streams shall be easily accessible by the ship. PRFs that are difficult to use and
poorly arranged can create a disincentive for ships to properly dispose of their waste while at the port or
terminal.
5.6.3 Waste handling equipment
There is a variety of equipment that can be used to collect, store and in some cases, treat or further process
the different waste streams collected at ports and terminals. The equipment selected should be suitable for
the type and quantity of waste.
Proper sighting at the berth of waste handling equipment should be considered. Poor siting and lack of
sufficient space for operation of equipment can raise safety concerns for ship personnel when using the PRF
equipment. It can also create a risk for discharge into the environment and possibly create a disincentive for
proper waste disposal.
5.6.4 Storage
Consideration should also be given to the period of time during which the fixed or mobile PRF can store
the ship-generated waste and cargo residues on site. This should also be taken into account in the PWMP.
Lengthy storage of waste should be avoided, as it can create stress on the supporting infrastructure and
impact the waste handling services for future ships. It can also affect the health and safety of workers and
the environment if stored waste quantities exceed storage capacities. PWMPs that do not arrange for routine
waste removal services shall ensure that waste storage receptacles of sufficient capacity and quantity are
provided. Conversely, PRFs that are serviced frequently do not necessarily require large capacity waste-
storage receptacles.
5.7 Participation in segregation, recycling or disposal programs
5.7.1 General
The provision for waste segregation can lead to increased participation in recycling programmes. For this
effort to be successful, segregated waste should remain segregated until the final treatment. Many PRFs can
be conveniently arranged to accommodate recycling and other waste management services. Additionally,
[5]
ships that implement ISO 21070 have waste segregation procedures that make operations at the PRF and
downstream waste management easier.
5.7.2 Recycling capabilities
Recycling is a process where materials, which are otherwise destined for final disposal are collected,
processed or reprocessed, and then reused. These materials all have useful chemical or physical properties
after having served their original purpose.
5.7.3 Final disposal
Final disposal of wastes should be viewed as a last option to be exercised only after alternatives have been
explored, including energy recovery from wastes, and deemed unattainable. Several options for final disposal
exist, and the benefits and drawbacks should be considered and documented in the port or terminal's waste
management strategy.
6 Port waste management plan (PWMP)
6.1 General
Ports and terminals should, at a minimum, provide PRFs for ship-generated waste and cargo residues. As
such, the PWMP takes into account the national waste management strategy and defines how and by whom

ISO/FDIS 16304:2026(en)
waste is collected at a port or terminal. This is necessary as waste streams received from ships calling on
ports or terminals must be dealt with in an environmentally sound manner. Developing and following such
a waste management strategy ensures that all parties involved in the generation, reception and transfer of
ship-generated waste and cargo residues conform to recognized practices and standards. This serves to
protect the health and quality of the port users, public and the environment.
There are five key elements that should be considered in a PWMP. They are:
a) development of PWMP;
b) publication of PWMP;
c) implementation of PWMP;
d) enforcement of delivery of ship-generated waste and cargo residues by competent authorities; and
e) monitoring the plan to ensure that all parties, including ships and facility providers adhere to the plan,
the plan is and remains fit for use and the reception facilities are adequate.
The development of a PWMP is the planning stage for the eventual provision of a PRF and is the most crucial
and time-consuming part of the process. First, the port should consider what waste reception services they
should provide and exactly how they can provide them. It is necessary for PWMP to manage the different
waste streams generated on board a ship in an efficient and environmentally sound manner that does
not cause undue delay to ships or disincentives to shipping. A PWMP can be developed in-house, or by a
consultant. The PWMP shall be transparent, auditable and include provisions for consultation with the
stakeholders. It should identify the major principles of waste minimization, management and disposal, while
ensuring the health, safety and security concerns of the port or terminal user. The PWMP should also result
in the development of a formal plan that is consulted upon, approved (if necessary), and used as the basis for
developing the day-to-day manual for the management and operation of the PRF.
The PWMP should include relevant information on the following key areas outlining pertinent procedures
and management measures, as appropriate:
— analysis of the relevant regulations;
— the waste management structure into which the PWMP fits;
— the official responsibilities of the port owners/operators and other relevant parties, and the different
governmental administrations involved in controlling the management of ship-generated waste and
cargo residues;
— geographical and administrative scope of the PWMP;
— official responsibilities within the management and oper

The development of adequate port waste reception facilities (PRFs) for ship-generated waste and cargo
residues is a major factor in the management of each of the shipboard waste streams covered by the
[1] [1]
International Convention for the Prevention of Pollution from Ships (MARPOL ) ) Annexes I to VI, as
[1][1]
amended, excluding Annex III (packaged dangerous goods). MARPOL requires the Parties to ensure the Formatted: Not Superscript/ Subscript
[1][1]
provision of adequate reception facilities in ports to receive these wastes. The Parties to MARPOL are
required to implement legislation to provide for PRFs. Regional and intergovernmental legislation has also
been developed. However, due to operational, ownership, geographic and legislative differences in ports, there
is a large disparity in how operations are conducted. To overcome some of the major issues, the International
Maritime Organization (IMO), through its Sub-Committee on Implementation of IMO Instruments (III)
[formerly the Sub-Committee on Flag State Implementation (FSI)] developed an action programme to tackle
the inadequacy of PRFs. Then, IMO adopted MEPC.83(44) Guidelines for Ensuring the Adequacy of Port Waste
[4]
Reception Facilities [4].
To obtain the most efficient management of waste and to reduce the time and resource burden in segregating
and handling waste in the ports, the concept of waste minimisationminimization has been integrated into this
document by incorporating the following principles:

especially with respect to health and safety on board ships and at ports and terminals. It has been

acknowledged within the IMO that standardized methodologies for waste management both on board ships
and ashore at PRFs would harmonize practices and ensure a smooth delivery of ship-generated waste and
[5][5]
cargo residues to shore-side facilities. ISO 21070 provides a methodology for ships to segregate their Formatted: Default Paragraph Font

Formatted: Default Paragraph Font
[5][5]
and cargo residues. However, ISO 21070 cannot work alone and requires a parallel International Standard
Formatted: Default Paragraph Font
that covers the reception of ship-generated waste. This document assists in the planning for the provision of

adequate PRFs.
[1][1]
Parties to MARPOL are obligated as Port States to ensure that port waste reception facilities (PRFs)
adequate to meet the needs of the ships using them without causing undue delay are provided at their ports
[1][1]
and terminals. MARPOL does not seek to regulate the management of ship-generated waste and cargo
residues at ports and terminals beyond the reception facility requirement. The IMO recognisesrecognizes the
need of managingto manage ship-generated waste and cargo residues at ports and terminals as part of an
environmentally sound management approach for avoiding, minimisingminimizing and eliminating pollution
from ships.
In consideration of the above, this document applies to the management of ship-generated waste and cargo

Formatted: Adjust space between Latin and Asian text,

Many states have implemented legislation, policies and national waste management strategies that govern the

management of waste received at PRFs. Such legislation should be considered when developing a port waste
Formatted: Adjust space between Latin and Asian text,
management strategy, as it will assist in determining how local compliance can affect the operation of PRFs
Adjust space between Asian text and numbers
within a port. Additionally, there can be a need for either licensing or local approvals, or both, and the port or
terminal operator should consider waste tracking and documentation.
The best possible environmental solution for waste recovery and disposal should be identified. Waste
management targets adopted by the national administration for ports and terminals within its jurisdiction can
be considered in the development of port waste management strategies. If there are no such targets, then the
port or terminal operator can consider developing them.
4.3 Technology
Formatted: Adjust space between Latin and Asian text,
Adjust space between Asian text and numbers, Tab stops:
Not at 0.71 cm
PRFs should use waste management technology that is current and applicable for ship-generated waste and
cargo residues expected from ships using the port or terminal. Recycling and reclamation of waste is Formatted: Adjust space between Latin and Asian text,
Adjust space between Asian text and numbers
preferable to disposal (see 6.5).6.5). Therefore, any waste management strategy should recognize and
promote alternative methods of waste management that utiliseutilize new and emerging technologies.
4.4 Infrastructure and support services
Formatted: Adjust space between Latin and Asian text,
Adjust space between Asian text and numbers, Tab stops:

The waste management strategy should be developed with an awareness of the infrastructure and support
services not only throughout the port or terminal, but also beyond those physical limits. There shall be in place Formatted: Adjust space between Latin and Asian text,
Adjust space between Asian text and numbers
suitableSuitable waste transport logistics, recycling facilities, treatment facilities, and if necessary, final
disposal sites. shall be in place. These treatment and disposal facilities are located within the port or outside
the port. Waste management strategies should also incorporate proactive mechanisms to inform and educate
those having an interest in using the PRF.
5 Design and operation of PRFs
5.1 General Formatted: Adjust space between Latin and Asian text,
Adjust space between Asian text and numbers, Tab stops:
Not at 0.71 cm
The types and number of ships normally calling at the port or terminal and the nature of operations should be
considered in the planning for the provision of a PRF. PRFs for relevant wastes shall be available without Formatted: Adjust space between Latin and Asian text,
Adjust space between Asian text and numbers
causing undue delay to ships or imposing economic or other disincentives for their use. The port waste
management plan (PWMP) will provideprovides options for waste collection and handling. The calculated PRF
capacity and the design of the PRF provide a foundation for the PWMP. However, for those waste volumes that
couldcan be anticipated to fluctuate widely over different periods, the provision of a PRF should be adapted
appropriately. The system designed to support and operate a PRF should consider the core components as
indicated through 5.2 to 5.7.5.2 to 5.7.

considerations should include an awareness of the impact on other port operations as well as the public areas
Formatted: Font: Bold
surrounding the port or terminal.
Formatted: HeaderCentered, Left
Larger ports and terminals require higher capacities or more diverse capabilities. Construction of a new port
or terminal may offer greater flexibility in design as opposed to making improvements to an existing PRF.
Regardless of the type of PRF that is chosen, the port or terminal geography and layout should be considered
as part of the design phase. The best way to collect each waste stream throughout the port or at the terminal
shall be determined. In a compact port with large berths, garbage waste disposal bins on each quay or a direct
transfer to the waste handler couldcan be implemented. However, in other port configurations, it can be better
to collect waste by barge. If the port is lock-bound, waste can be landed upon entry or exit to the lock.
A port or terminal that is planning to increase operations in the future can see a rise in shipping waste volumes.
This can result in a need of additional PRF capability during planning activities.

Not all waste streams willare necessarily be produced by every ship or be offloaded in every port. Additionally,
in some circumstances it can be necessary or desirable for ships to offload waste, such as food waste and cargo

residues that couldcan be discharged into the sea under the provisions of MARPOL but due to operations,
company policy, or other considerations, the master of the ship chooses to offload these wastes ashore.
Therefore, the PWMP should consider the following:
