(Main)Collection, logistics & treatment requirements for end-of-life household appliances containing volatile fluorocarbons or volatile hydrocarbons
Collection, logistics & treatment requirements for end-of-life household appliances containing volatile fluorocarbons or volatile hydrocarbons
This European Standard defines requirements for the end of life handling, transportation, storage, sorting and treatment of WEEE household appliances containing volatile fluorocarbons, volatile hydrocarbons, or both. Furthermore, this standard only applies to WEEE household appliances that use heat-transfer media other than water e.g. refrigerators, freezers, heat pump tumble dryers, de-humidifiers and portable air conditioners. Discarded appliances covered by this standard will have been deposited at a collection facility as domestic WEEE. The European Standard describes requirements for the removal of volatile fluorocarbons and volatile hydrocarbons. These substances can be found as refrigerant in the refrigerating system (partly dissolved in the oil) and as blowing agent in the insulation foam of discarded household appliances. NOTE This standard has been prepared to fulfil the requirements of Directive 2002/96/EC but does not preclude the procedures described herein from being used to treat appliances that are not commonly found in private households. It defines requirements pertaining to producers, WEEE compliance schemes (acting on behalf of producers) and waste treatment facilities so as to ensure the provisions of applicable national laws resulting from European legislation are fulfilled. These requirements are intended to define procedures, parameters based on the best available technologies at the time of the publication; however, provisions laid down by national regulatory bodies will continue to additionally apply. This standard only describes the results to be achieved, it does not specify how they are to be achieved nor does it prescribe the use of any specific technology. This European Standard does not generally cover collection facilities, nor does it cover how appliances arrive at these facilities. However, this standard does address the sorting of heat-pump tumble dryers from other types of tumble dryer, a task that could be performed at a collection facility. This European Standard defines requirements relating to handling, transportation, sorting and treatment of WEEE covered by the scope of this standard. This standard does not include any activity prior to delivery to a logistic facility.

Zahteve za zbiranje, prevoz in ravnanje z gospodinjskimi napravami s pretečeno uporabnostjo, ki vsebujejo hlapne fluorokarbone ali hlapne ogljikovodike
Ta evropski standard določa zahteve za upravljanje, prevoz, skladiščenje, razvrščanje in ravnanje z gospodinjskimi napravami s pretečeno uporabnostjo, ki spadajo med odpadno električno in elektronsko opremo ter vsebujejo hlapne fluorokarbone, hlapne ogljikovodike ali oboje. Poleg tega se ta evropski standard uporablja le za gospodinjske naprave, ki spadajo med odpadno električno in elektronsko opremo ter uporabljajo sredstva za prenos toplote, ki niso voda, npr. hladilniki, zamrzovalniki, sušilni stroji s toplotno črpalko, razvlaževalniki in prenosne klimatske naprave. Zavržene naprave, zajete v tem evropskem standardu, se zbirajo v obratih za zbiranje kot domača odpadna električna in elektronska oprema. Evropski standard opisuje zahteve za odstranitev hlapnih fluorokarbonov in hlapnih ogljikovodikov. Te snovi je mogoče najti kot hladilo v hladilnem sistemu (delno raztopljene v olju) in kot penilec v izolacijski peni zavrženih gospodinjskih naprav. Standard določa zahteve v zvezi s proizvajalci, shemami skladnosti odpadne električne in elektronske opreme (ki delujejo v imenu proizvajalcev) ter napravami za obdelavo odpadkov, da se zagotovi izpolnjevanje določb veljavnih nacionalnih zakonov, ki izhajajo iz evropske zakonodaje. Te zahteve so namenjene definiciji postopkov in parametrov, ki temeljijo na najboljših razpoložljivih tehnologijah v času izdaje; vendar še naprej dodatno veljajo določbe nacionalnih regulativnih organov. Ta standard le opisuje rezultate, ki jih je treba doseči, pri čemer ne določa, na kakšen način jih je treba doseči, in ne predpisuje uporabe posebne tehnologije. Ta evropski standard ne opisuje obratov za zbiranje na splošno, prav tako ne opisuje, kako se naprave dostavijo v te obrate. Vendar pa ta standard obravnava ločevanje sušilnih strojev s toplotno črpalko od drugih vrst sušilnih strojev; to nalogo lahko izpolnjevali obrati za zbiranje. Ta evropski standard določa zahteve v zvezi z upravljanjem, prevozom, razvrščanjem in ravnanjem z odpadno električno in elektronsko opremo, ki je zajeta v tem standardu. Ta standard ne zajema dejavnosti pred prihodom v logistični obrat.

Introduction
This document establishes requirements for the transportation, sorting and treatment of
household appliances containing volatile fluorocarbons or volatile hydrocarbons after they
have been discarded as waste electrical and electronic equipment (WEEE).
The methodologies for the inspection of the performance of treatment systems for household
refrigerators and freezers in step 2 treatment was developed in the early 1990s. The
methodologies used for performance tests since then have been created to evaluate the
efficiency of treatment plants designed to recover VFCs from insulating foam. The evaluation
criteria used for performance testing are based on the VFC content of household refrigerators
and freezers that were produced in the 1970s and 1980s.
The increasing appearance on the recycling market of appliances with VFC-free insulation
(foamed with VHC) has had a strong impact on the general framework conditions for
performance testing over the last few years. In the early 1990s the quantity of R11 (a VFC)
was reduced by approximately 50 %. R11 was then largely phased out in favour of VHCs in
the early 2000s.
Consequently the expected values from step 2 treatment that had been achieved in the 1990s
are no longer applicable for the appliances that are recycled today. Nowadays more and more
VFC-free appliances and appliances containing reduced quantities of VFC come back for
recycling.
The WEEE within the scope of this standard could contain substances that if released
untreated to the atmosphere could contribute to ozone depletion or global warming. The
substances may be present in the refrigerating system and in insulating foam. This standard
seeks to reduce the environmental impact caused by such WEEE by defining requirements
covering sorting, transportation, handling and treatment. It covers how substances with a high
global warming potential and/or ozone depletion potential are removed from WEEE and
subsequently treated so as to significantly reduce environmental impacts.
By addressing the above issues this standard supports the WEEE Directive 2002/96/EC.

1 Scope
This European Standard defines requirements for the end of life handling, transportation,
storage, sorting and treatment of WEEE household appliances containing volatile
fluorocarbons, volatile hydrocarbons, or both. Furthermore, this European Standard only
applies to WEEE household appliances that use heat-transfer media other than water e.g.
refrigerators, freezers, heat pump tumble dryers, de-humidifiers and portable air conditioners.
Discarded appliances covered by this European Standard will have been deposited at a
collection facility as domestic WEEE.
The European Standard describes requirements for the removal of volatile fluorocarbons and
volatile hydrocarbons. These substances can be found as refrigerant in the refrigerating
system (partly dissolved in the oil) and as blowing agent in the insulating foam of discarded
household appliances.
NOTE This European Standard has been prepared to fulfil the requirements of Directive 2002/96/EC but does not
preclude the procedures described herein from being used to treat appliances that are not commonly found in
private households.
It defines requirements pertaining to producers, WEEE compliance schemes (acting on behalf
of producers) and waste treatment facilities so as to ensure the provisions of applicable
national laws resulting from European legislation are fulfilled. These requirements are
intended to define procedures, parameters based on the best available technologies at the
time of the publication; however, provisions laid down by national regulatory bodies will
continue to additionally apply. This standard only describes the results to be achieved, it does
not specify how they are to be achieved nor does it prescribe the use of any specific
technology.
This European Standard does not generally cover collection facilities, nor does it cover how
appliances arrive at these facilities. However, this standard does address the sorting of heat-
pump tumble dryers from other types of tumble dryer, a task that could be performed at a
collection facility.
This European Standard defines requirements relating to handling, transportation, sorting and
treatment of WEEE covered by the scope of this standard. This standard does not include any
activity prior to delivery to a logistic facility.

4 Requirements prior to treatment
4.1 General
The requirements prior to treatment apply to all operators involved in handling, transportation,
sorting, and storage of WEEE of appliances according to the scope of this document.
WEEE covered by this standard shall be stored, handled and transported in a way that
damage of any part of the refrigerant system or the insulating foam is avoided. In particular,
appropriate measures shall be introduced and documented so as to:
• prevent, as far as reasonably practicable, the emission of VFCs;
• reduce the risk of explosion due to the release of VHCs by ensuring that levels and
measures are consistent with health and safety legislation.
NOTE 1 These measures are required to ensure that VFCs and VHCs are not released due mishandling, since
leakage of VFC could damage to the environment and leakage of VHC in confined places could result in an
explosion.
NOTE 2 Employers should ensure that they are familiar with the general requirements for health and safety as laid
down in Directive 89/391 EEC and also the particular requirements set out in Directive 1999/92/EC for the safety
and health protection of workers potentially at risk from explosive atmospheres and Directive 94/9/EC on
equipment and protective systems intended for use in potentially explosive atmospheres (ATEX).
If leakage of oil is detected, appropriate measures shall be taken to minimise environmental
impacts.
4.2 Site requirements
All sites shall be secured against unauthorised access or egress.
The operator shall possess infrastructure in terms of size, technologies installed, and
characteristics of the operations that are suitable for the activities performed on site.
Suitability of site shall be assessed by an operational risk management process for all tasks
performed on site and include the identification of hazards, the assessment of risk and, where
appropriate, the elimination or reduction of the risk, and documentation of the process.
NOTE Technical requirements for sites for storage and treatment are described in Annex III of Directive
2002/96/EC.
4.3 Transportation
It is permitted to transport WEEE within the scope of this standard with other WEEE providing
the WEEE covered by this standard is not damaged as a consequence of this optimisation.
---------------------- Page: 11 ----------------------
SIST EN 50574:2012
EN 50574:2012 – 10 –
The WEEE within the scope of this standard shall not be crushed, compacted, or handled in a
way that could damage any part of the refrigerant system or the insulating foam. In particular
during transportation, internal transit or when loading and unloading appliances, care shall be
taken to ensure that appliances’ refrigerating systems and cabinets are not damaged.
4.4 Sorting
WEEE within the scope of this standard shall be separated from other WEEE at logistic
facilities and delivered to treatment facilities primarily specialized in the treatment of WEEE
containing VFCs or VHCs. This sorting shall only be performed by trained or adequately
supervised personnel.
To ensure that heat pump tumble dryers are treated correctly, as a precondition it is
necessary that they are first identified and correctly sorted (see Annex D).The treatment of
these appliances containing VFC shall be carried out only at facilities that perform step 1
treatment.
NOTE Treating WEEE without first separating appliances within the scope of this standard from other WEEE could
result in emission of substances that are either harmful to the environment or present a risk of fire or explosion.
Separating VHC-containing appliances from VFC-containing appliances for separate
treatment is only permitted if analytical evidence exists that identifies the blowing agents for
each appliance.
4.5 Compliance criteria
Parties responsible for any action covered by 4.1 through 4.4 shall have procedures in place
to ensure and document compliance with the requirements set there.
These procedures (e.g. trainings, operational measures) and their regular approval shall be
documented (for instance as part of that organisation’s quality, environmental, or health and
safety management system) and periodically audited. The results of such audits shall be
made available to the party having responsibility for the quality of WEEE delivered for
treatment on request (normally the responsible take-back party).
5 Requirements for treatment facilities
5.1 General
The operator of the treatment facility shall ensure that all removed VFCs and VHCs are
captured and subsequently disposed of, or recovered, in accordance with requirements set by
the responsible take back parties. Removed VFCs, VHCs and mixtures thereof shall either be
transported to an authorised facility for recovery or disposal, or recovered or destroyed by on-
site conversion.
NOTE 1 Requirements for transportation are given by national measures implementing the “Accord européen relatif
au transport international des marchandises dangereuses par route” (ADR).
NOTE 2 Recovery and destruction of used controlled ozone depleting substances is covered by EC Regulation No
1005/2009.
Separated VFCs shall be converted by a suitable process so that they no longer have the
potential for causing depletion of the ozone layer. Where the VFCs are sent for conversion to
a facility remote from the treatment facility, records of bills or delivery sheets shall be
documented and maintained.
NOTE 3 All treatment facilities that treat WEEE in accordance with this standard will need to comply with explosion
protection measures. Refer to Directive 1999/92/EC on minimum requirements for improving the safety and health
protection of workers potentially at risk from explosive atmospheres and Directive 94/9/EC on the approximation of
the laws of the Member States concerning equipment and protective systems intended for use in potentially
explosive atmospheres (ATEX).
---------------------- Page: 12 ----------------------
SIST EN 50574:2012
– 11 – EN 50574:2012
NOTE 4 Attention is drawn to the fact that national emission limits on VFCs and VHCs may apply.
NOTE 5 In practice, explosions inside shredders can be avoided by controlling ambient conditions. Examples of
measures to control those conditions include a) dilution of the VHC fraction in the local atmosphere by blowing air
into the process or, b) reduction of the oxygen content by substituting air with inert gases and c) using alternative
explosion proof processing-technologies.
All separated VFCs and VHCs or admixtures thereof shall be carefully stored, handled and
transported to avoid any emissions before their recovery or destruction.
5.2 Step 1 treatment
This section applies to all WEEE within the scope of this standard.
1) All refrigerants and all oil shall be removed from the refrigerating system;
2) All refrigerants shall be separated from oil;
3) All oil shall be contained within a closed system until the concentration of refrigerant is
below 0,2 % w/w VFC;
NOTE The VFC content should be measured and expressed as concentration of R12 in the oil.
4) No residual VFC within the oil shall be allowed to be released to the atmosphere;
5) The total mass of refrigerants removed from the refrigerating system (sum of VHCs and
VFCs) shall be monitored and documented continuously.
5.3 Step 2 treatment
This section applies to WEEE containing insulating foam with either VFCs or VHCs.
1) The treatment of appliances in step 2 is normally carried out with step 1 treated
appliances (called “cabinets”);
2) Insulating foam shall not be manually removed;
NOTE 1 Future insulation material technologies may necessitate a manual dismantling of insulating foam.
3) The crushing of cabinets and the separation of crushed fractions shall be performed in a
way so that emissions of VFCs and VHCs to the atmosphere are minimised according to
national legislation;
4) The residual content of VFCs contained in the separated metal and plastics fractions
shall be minimised;
5) The residual VFCs within the crushed insulating foam shall not be released to the
atmosphere. They shall be converted into compounds that do not deplete the ozone layer;
