Stationary source emissions - Determination of greenhouse gas (GHG) emissions in energy-intensive industries - Part 5: Lime industry

The verified standard covers the determination of the most significant GHG emissions and their sources during the (do)lime production process; starting in the quarry; and ending at the run-of-kiln (do)lime product. The standard also covers some optional common downstream processes such as "milling" and "hydration".

Emissionen aus stationären Quellen - Bestimmung von Treibhausgasen (THG) aus energieintensiven Industrien - Teil 5: Kalkindustrie

Diese Europäische Norm stellt eine harmonisierte Methodik zur Berechnung der Treibhausgasemissionen aus der Kalkindustrie bereit. Sie umfasst die Herstellung von Kalk und in der Anlage hergestellte nachgelagerte Kalkprodukte, z. B. gemahlener oder gelöschter Kalk. Diese Norm ermöglicht die Berichterstattung zu Treibhausgasemissionen für verschiedene Zwecke und auf unterschiedlicher Basis, zum Beispiel auf Anlagen  bzw. Werkbasis, auf Unternehmensbasis (nach Land oder nach Region) oder auf internationaler Organisationsbasis.
Da Kalk als generische Bezeichnung für Branntkalk, Dolomitkalk und gesinterten Dolomitkalk definiert ist, muss diese Norm Anlagen abdecken, in denen mindestens eines dieser Produkte hergestellt wird.
Diese Europäische Norm behandelt alle folgenden direkten und indirekten Treibhausgasquellen nach ISO 14064 1:
direkte Treibhausgasemissionen aus Treibhausgasquellen, die im Besitz des Unternehmens sind oder von diesem kontrolliert werden, z. B. Emissionen aus folgenden Quellen:
Kalzinierung der Carbonate und Verbrennung des im Brenngut enthaltenen organischen Kohlen¬stoffs;
Verbrennung der Ofenbrennstoffe (fossile Ofenbrennstoffe, alternative fossile Brennstoffe, Mischbrennstoffe mit biogenem Kohlenstoffanteil, Biomassebrennstoffe und Biobrennstoffe) im Zusammenhang mit der Kalkherstellung und/oder dem Trocknen der Rohstoffe;
Verbrennung der Nicht-Ofenbrennstoffe (fossile Ofenbrennstoffe, Mischbrennstoffe mit biogenem Kohlenstoffanteil, Biomassebrennstoffe und Biobrennstoffe) im Zusammenhang mit Betriebseinrichtungen und vor Ort eingesetzten Fahrzeugen, dem Heizen/Kühlen und anderen Verwendungen vor Ort;
Verbrennung der Brennstoffe zur Stromerzeugung vor Ort;
—   indirekte Treibhausgasemissionen aus der Erzeugung importierter elektrischer Energie, Wärme oder Dampf, die von der Organisation verbraucht werden;
—   sonstige indirekte Treibhausgasemissionen außer energiebedingte indirekte Treibhausgasemissionen, die eine Folge der Tätigkeiten einer Organisation sind, die jedoch aus den Treibhausgasquellen stammen, die sich im Besitz anderer Organisationen befinden oder von diesen kontrolliert werden, z. B. aus importiertem Brenngut.
Diese Norm ist in Verbindung mit FprEN 19694 1 anzuwenden, in der generische, allgemeine Anforderungen, Definitionen und Regeln behandelt sind und die für die Bestimmung von Treibhausgasemissionen aus allen energieintensiven Sektoren gelten, und in der gemeinsame methodische Aspekte beschrieben und die Einzelheiten zur Anwendung dieser Regeln festgelegt sind. Durch die Anwendung dieser Norm auf sektorspezifische Normen sind die Genauigkeit, Präzision und Wiederholbarkeit der Ergebnisse sichergestellt, daher handelt es sich hierbei um eine normative Bezugsnorm.
Gemeinsam stellen diese Normen ein harmonisiertes Verfahren bereit zur:
a)   Messung, Prüfung und Quantifizierung der Treibhausgasemissionen;
b)   Bewertung des Treibhausgasemissionsniveaus von Produktionsprozessen im zeitlichen Verlauf an Produktionsstandorten;
c)   Erarbeitung und Bereitstellung verlässlicher, genauer und hochwertiger Informationen für die Erstellung von Berichten und für Verifizierungszwecke.
Nach dieser Norm dürfen an keiner Stelle THG Bewertungsmechanismen zur Verrechnung von Treibhaus-gasemissionen, darunter freiwillige Verrechnungsmodelle oder nationale bzw. internationale anerkannte Verrechnungsmechanismen, angewendet werden.

Émissions de sources fixes - Détermination des émissions des gaz à effet de serre dans les industries à forte intensité énergétique - Partie 5: Industrie de la chaux

La présente Norme européenne fournit une méthodologie harmonisée pour calculer les émissions de GES de l'industrie de la chaux. Elle inclut la fabrication de la chaux et les sous-produits dérivés en aval fabriqués en usine, tels que la chaux broyée ou hydratée. La présente norme permet de déclarer les émissions de GES à différentes fins et sur différentes bases, telles qu'au niveau d'une usine, d'une entreprise (par pays ou par région) ou d'une organisation internationale.
La chaux étant définie comme le terme générique de la chaux vive, de la dolomie et de la dolomie frittée, les usines fabriquant au moins l'un de ces produits doivent être couvertes par la présente norme.
La présente Norme européenne examine toutes les sources suivantes d'émissions directes et indirectes de GES concernées et définies dans l'ISO 14064 1 :
-   émissions directes de gaz à effet de serre provenant de sources de GES détenues ou contrôlées par l'entreprise, les émissions émanant des sources suivantes :
-   calcination des carbonates et combustion du carbone organique contenu dans le calcaire d'alimentation des fours ;
-   combustion des combustibles alimentant les fours (combustibles fossiles utilisés pour alimenter les fours, combustibles fossiles de substitution, combustibles mixtes contenant du carbone biogénique, combustibles issus de la biomasse et biocarburants) et liés à la production de chaux et/ou au séchage des matières premières ;
-   combustion des combustibles non destinés à alimenter les fours (combustibles fossiles, combustibles fossiles de substitution, combustibles mixtes contenant du carbone biogénique, combustibles issus de la biomasse et biocarburants) et liés aux équipements et véhicules utilisés sur site, au chauffage/refroidissement et autres utilisations sur site ;
-   combustion des combustibles pour la production d'électricité sur site.
-   émissions indirectes de gaz à effet de serre provenant de la génération d'électricité, de chaleur ou de vapeur importée qui est consommée par l'organisation ;
-   autres émissions indirectes de gaz à effet de serre, autres que les émissions indirectes de GES des énergies, qui résultent des activités d'une organisation mais qui proviennent des sources de gaz à effet de serre qui sont détenues ou contrôlées par d'autres organisations, telles que le calcaire importé pour l'alimentation des fours.
La présente Norme européenne doit être utilisée conjointement avec le FprEN 19694-1 qui contient des exigences générales génériques, des définitions et des règles applicables pour la détermination des émissions de GES pour tous les secteurs consommateurs d'énergie, expose des questions méthodologiques communes et détaille l'application des règles exposées. L'application de la présente norme aux normes sectorielles garantit l'exactitude, la fidélité et la reproductibilité des résultats et est, de ce fait, une norme de référence normative.
Ces normes fournissent conjointement une méthode harmonisée pour :
a)   mesurer, contrôler et quantifier les méthodes relatives aux émissions de GES ;
b)   évaluer au fil du temps le niveau des émissions de GES des procédés de fabrication des sites de production ;
c)   établir et fournir des informations fiables, précises et de qualité à des fins de déclaration et de vérification.
Les mécanismes de compensation des émissions de GES, incluant mais sans s'y limiter les programmes de compensation volontaires ou les mécanismes de compensation reconnus à l'échelle nationale ou internationale, ne doivent être utilisés à aucun moment de l'évaluation des GES conformément à la présente norme.

1 Scope
This European Standard provides a harmonized methodology for calculating GHG emissions from the
lime industry. It includes the manufacture of lime, and any downstream lime products manufactured at
the plant, such as ground or hydrated lime. This standard allows for reporting of GHG emissions for
various purposes and on different basis, such as plant basis, company basis (by country or by region) or
international organization basis.
Since lime is defined as the generic name for quicklime, dolime and sintered dolime, plants
manufacturing at least one of these products shall be covered by this standard.
This European Standard addresses all of the following direct and indirect sources of GHG included as
defined in ISO 14064-1:
— direct greenhouse gas emissions from greenhouse gas sources that are owned or controlled by the
company, such as emissions resulting from the following sources:
— calcination of carbonates and combustion of organic carbon contained in the kiln stone;
— combustion of kiln fuels (fossil kiln fuels, alternative fossil fuels, mixed fuels with biogenic
carbon content, biomass fuels and bio fuels) related to lime production and/or drying of raw
materials;
— combustion of non-kiln fuels (fossil kiln fuels, mixed fuels with biogenic carbon content,
biomass fuels and bio fuels) related to equipment and on-site vehicles, heating/cooling and
other on-site uses;
— combustion of fuels for on-site power generation.
— indirect greenhouse gas emissions from the generation of imported electricity, heat or steam
consumed by the organization;
— other indirect greenhouse gas emissions, other than energy indirect GHG emissions, which is a
consequence of an organization's activities, but arises from greenhouse gas sources that are owned
or controlled by other organizations such as from imported kiln stone.
This European Standard is to be used in conjunction with EN 19694-1, which contains generic, overall
requirements, definitions and rules applicable to the determination of GHG emissions for all energy-
intensive sectors, provides common methodological issues and defines the details for applying the
rules. The application of this standard to the sector-specific standards ensures accuracy, precision and
reproducibility of the results and is for this reason a normative reference standard.
Together these standards provide a harmonized method for:
a) measuring, testing and quantifying methods for GHG emissions;
b) assessing the level of GHG emissions performance of production processes over time, at production
sites;
c) establishment and provision of reliable, accurate and quality information for reporting and
verification purposes.
GHG emissions offset mechanisms, including but not limited to voluntary offset schemes or nationally
or internationally recognized offset mechanisms, shall not be used at any point in the GHG assessment
according to this standard.

5 Introduction
5.1 Overview of the lime manufacturing process
Lime manufacture includes three main process steps: 1
a) kiln stone preparation including quarrying, crushing, washing, screening and transporting to the
lime kiln;
b) kiln operation including lime manufacture using pyro-processing to calcine the kiln stone in a lime
kiln;
c) downstream processing including crushing, screening, transporting to silos, grinding/milling,
hydrating and packing.

Figure 1 — Process steps in lime manufacture
A lime manufacturing plant may also encompass the use of additional fuel for on-site power generation
and for preparation or processing of fuels for use in the plant.
There are two main sources of direct greenhouse gas emissions in the lime manufacturing process:
— calcination of kiln stone through pyro-processing in the lime kiln (known as process emissions);
— combustion of kiln fuels (known as combustion emissions).
These two sources are described in more detail below.
10

---------------------- Page: 12 ----------------------

SIST EN 19694-5:2017
EN 19694-5:2016 (E)
Other minor direct greenhouse gas emissions may come from non-kiln fuels such as on-site transport,
pumps, room heating and other on-site uses.
The main source of energy indirect greenhouse gas emissions in the lime manufacturing process come
from external power production or transport but these sources are relatively small in comparison to
the direct greenhouse gas emissions.
For the lime sector, only the greenhouse gas CO is relevant as demonstrated by different field tests.

5.2 Direct greenhouse gas emissions from calcination of kiln stone (process emissions)
In the lime manufacturing process, CO is released due to the chemical decomposition of calcium,
2
magnesium and other carbonates in the kiln stone when the kiln stone is heated to high temperatures:
CaCO →+CaO CO
32
(1)
MgCO →+MgO CO
32
(2)
This process is called "calcining" or "calcination". It results in direct emissions of CO through the kiln
2
stack. When considering CO emissions due to calcination, two components can be distinguished:
2
— CO from kiln stone used for lime production;
2
— CO from materials leaving the kiln system as partly calcined LKD.
2
The CO2 from lime production is dependent on the quality of the final lime product, i.e. the degree of
calcination. This varies depending on the kiln design and targeted final lime product properties. The
amount of LKD leaving the kiln system varies with kiln type. The associated greenhouse gas emissions
are likely to be relevant and so shall be accounted for.
CO emissions from calcination can be determined as a part of the measurement method or by using the
2
following mass-balance-based methods which are in principle equivalent:
a) the Input Method, based on the mass of kiln stone entering the kiln and chemical composition of
the limestone, lime and LKD leaving the kiln system;
b) the Output Method, based on the mass and chemical composition of the lime and LKD leaving the
kiln system;
c) direct greenhouse gas emissions from organic carbon in kiln stone.
Some kiln stone sources contain a small fraction of organic carbon, which can be expressed as total
organic carbon (TOC) content. Organic carbon in the kiln stone is converted to CO during pyro-
2
processing. The contribution of this component to the overall CO emissions is typically very small. The
2
organic carbon content of kiln stone can, however, vary substantially between locations and shall be
assessed.
5.3 Direct greenhouse gas emissions from fuels for kiln operation (combustion
emissions)
The lime industry uses various fossil fuels to heat the kiln, including natural gas, coal and fuel oil. In
recent years, fuels derived from waste materials have become important substitutes. These alternative
fuels (AF) include fossil fuel-derived fractions, such as waste oil, as well as biomass-derived fractions,
such as waste wood. Furthermore, fuels are increasingly used which contain both fossil and biogenic
carbon, such as municipal and pre-treated industrial wastes or waste tyres (containing natural and
synthetic rubber).

EN 19694-5:2016 (E)
Both traditional and AF result in direct greenhouse gas emissions through the kiln stack. However,
biomass fuels and the biomass component of mixed fuels are considered “climate-neutral” in
accordance with IPCC definitions.
Greenhouse gas emissions from combustion of fuels can be calculated based on the mass, calorific value
and chemical composition of fuels entering the kiln.
The mass-balance-based method used in this standard is compatible with the 2006 IPCC Guidelines for
National Greenhouse Gas Inventories issued by the Intergovernmental Panel on Climate Change (IPCC).
Alternatively, kiln GHG emissions, from combustion, calcination and organic carbon in the kiln stone,
can be determined by direct measurement at the kiln stack using the stack-measurement-based
method. Emissions from the kiln stack all sources are determined based on continuous measurement of
the concentration of the relevant GHG in the flue gas and of the flue gas volume flow. For the stack-
measurement-based method non-kiln emissions are measured using a mass balance approach similar
to the mass-balance-based method. Direct greenhouse gas emissions from non-kiln fuels (combustion
emissions)

General information regarding the preparation of EN ISO 19694 Part 1 to 6

By end of 2010 the European Commission/EFTA gave Mandate M/478 to CEN entrusting CEN
to produce and adopt Standards, in particular containing harmonized methods for:

a. Measuring, testing and quantifying greenhouse gas (GHG) emissions from sector-
specific sources

b. Assessing the level of GHG emissions performance of production processes over
time, at production sites;

c. Establishing and providing reliable, accurate and quality information for reporting and
verification purposes.

Based on a gap analysis it was agreed to describe the assessment methodologies of the five
energy-intensive industry sectors steel-, cement -, aluminum-, lime- and ferroalloy industry as
well as general aspects in the six standards. As sector-specific knowhow was essential, the
concerned industry sectors (companies and associations) have been engaged extensively in the
development of the methodologies as well as the draft standards.
The methods of determination of green house gases (GHG) in these five energy intensive
industries were subject to comprehensive verification exercises (field tests) which were
financially supported by EC/EFTA and which reflect especially the uncertainties obtained.

The scope of the six standards is limited to the above described mandated frame and cannot be
arbitrarily enlarged.

Foreword
This document (TC 264 WI 00264146) has been prepared by Technical Committee CEN/TC 264 “Air quality”,
the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex D, which is an integral part of this document.
1 Scope
This standard provides a harmonised methodology for calculating GHG emissions from the lime industry. It
includes the manufacture of lime, and any downstream products manufactured at the plant, such as ground or
hydrated lime. This standard allows for reporting of GHG emissions for various purposes and on different
basis, such as plant basis, company basis (by country or by region) or international group basis.
Since lime is defined as the generic name for quicklime, dolime and sintered dolime, the plants manufacturing
at least one of these products shall be covered by this standard.
This standard addresses all of the following direct and indirect sources of GHG included as defined in
ISO 14064-1:
 Scope 1 – Direct GHG emissions from sources that are owned or controlled by the company, such as
emissions resulting from the following sources:
 Process: Calcination of carbonates and combustion of organic carbon contained in the kiln stone
 Combustion of kiln fuels (fossil kiln fuels, alternative fossil fuels, mixed fuels with biogenic
carbon content, biomass fuels and bio fuels) related to lime production and/or drying of raw
materials
 Combustion of non-kiln fuels (fossil kiln fuels, mixed fuels with biogenic carbon content, biomass
fuels and bio fuels) related to equipment and on-site vehicles, room heating/cooling
 Combustion of fuels for on-site power generation
 Scope 2 – Indirect GHG emissions from the generation of purchased electricity consumed in the
company’s owned or controlled equipment
 Scope 3 – Indirect GHG emissions from imported kiln stone
This standard shall be used in conjunction with standard “prEN xxxxx Stationary source emissions —
Determination of Greenhouse Gas (GHG) emissions in energy intensive industries — Part 1: General aspects”
which contains generic, overall requirements, definitions and rules applicable to the determination of GHG
emissions for all energy-intensive sectors, provides common methodological issues and defines the details for
applying the rules. The application of this standard to the sector-specific standards ensures accuracy,
precision and reproducibility of the results and is for this reason a normative reference standard.
Together these standards provide a harmonised method for:

Figure 1 — Process steps in lime manufacture
A lime manufacturing plant may also encompass the use of additional fuel for on-site power generation and for
preparation or processing of fuels for use in the plant.
There are two main sources of direct GHG emissions in the lime manufacturing process:
 calcination of kiln stone through pyro-processing in the lime kiln (known as process emissions)
 combustion of kiln fuels (known as combustion emissions)
These two sources are described in more detail below.
Other minor direct emissions of GHG may come from non-kiln fuels such as on-site transport, pumps, room
heating,
Minor GHG emissions may come from indirect sources such as from external power production or transport.
For the lime sector, only the greenhouse gas CO is relevant as demonstrated in different field tests. Details
2
about these tests are provided in Annex A.
GHG from calcination of kiln stone (process emissions)
In the lime manufacturing process, CO is released due to the chemical decomposition of calcium, magnesium
2
and other carbonates in the kiln stone:
CaCO + heat → CaO + CO
3 2
(1)
MgCO + heat → MgO + CO
3 2
(2)
This process is called "calcining" or "calcination". It results in direct CO emissions through the kiln stack.
2
When considering CO emissions due to calcination, two components can be distinguished:
2
 CO from kiln stone used for lime production;
2
 CO from materials leaving the kiln system as partly calcined lime kiln dust (LKD).
2
The CO from lime production is dependent on the quality of the final lime product, i.e. the degree of
2
calcination. This varies depending on the kiln design and targeted final lime product properties. The amount of
LKD leaving the kiln system varies with kiln type. The associated GHG emissions are likely to be relevant and
so shall be accounted for.
CO emissions from calcination can be calculated in the following ways which are in principle equivalent:
2
a) The Input Method - based on the mass of kiln stone entering the kiln and chemical composition of the
limestone, lime and LKD leaving the kiln system
b) The Output Method - based on the mass and chemical composition of the lime and LKD leaving the kiln
system
GHG from organic carbon in kiln stone
Some kiln stone sources contain a small fraction of organic carbon, which can be expressed as total organic
carbon (TOC) content. Organic carbon in the kiln stone is converted to CO during pyro-processing. The
2
contribution of this component to the overall CO emissions is typically very small. The organic carbon
2
contents of kiln stone can, however, vary substantially between locations and needs to be assessed as part of
the determination of GHG emissions.

The lime industry uses various fossil fuels to heat the kiln, including natural gas, coal and fuel oil. In recent
years, fuels derived from waste materials have become important substitutes. These alternative fuels (AF)
include fossil fuel-derived fractions, such as waste oil, as well as biomass-derived fractions, such as waste
wood. Furthermore, fuels are increasingly used which contain both fossil and biogenic carbon, such as
municipal and pre-treated industrial wastes or waste tyres (containing natural and synthetic rubber).
Both traditional and AF result in direct GHG emissions through the kiln stack. However, biomass fuels and the
biomass component of mixed fuels are considered “climate-neutral” in accordance with IPCC definitions.
GHG emissions from combustion of fuels can be calculated based on the mass, calorific value and chemical
composition of fuels entering the kiln.
The basic calculation methods used in this standard are compatible with the 2006 IPCC Guidelines for
National Greenhouse Gas Inventories issued by the Intergovernmental Panel on Climate Change (IPCC).
Alternatively, kiln GHG emissions, from combustion, calcination and organic carbon in the kiln stone, can be
determined by direct measurement at the kiln stack. Emissions from all sources are determined based on
continuous measurement of the concentration of the relevant GHG in the flue gas and of the flue gas volume
flow.
GHG from non-kiln fuels (combustion emissions)
GHG emissions from use of fuels in non-kiln applications which are part of the lime manufacturing plant, such
as on-site transport, fuel heating, and room heating are determined in a similar way to the GHG from fuels for
kiln operation.
GHG from indirect sources
In lime manufacture the main indirect emission source is electricity purchased by the plant but generated off-
site. Where kiln stone is imported to the plant, the emissions associated with its manufacture to the plant shall
be included within the scope of this standard. The emissions associated with the off-site transport of
purchased kiln stone to the plant may be included within the scope of this standard.
6 System boundaries
The operator shall define appropriate boundaries in line with ISO 14064-1 which distinguishes between
organizational and operational boundaries.
6.1 Organizational boundaries
Organizational boundaries define which parts of an organization – for example wholly owned operations, joint
ventures and subsidiaries – are covered by an inventory, and how the emissions of these entities are
consolidated.
The rules for defining Organisational Boundaries in prEN xxx “Stationary source emissions — Determination
of Greenhouse Gas (GHG) emissions in energy intensive industries — Part 1: General aspects” shall be
applied.
In particular, the lime industry shall include the following types of activities:
 Kiln stone preparation including quarrying, crushing, washing, screening and transporting to the lime kiln
 Calcination in the lime kiln
 Downstream processing including crushing, screening, transporting to silos, grinding/milling, hydrating
and packing
 Fuel use for on-site power generation; and
9

---------------------- Page: 13 ----------------------
oSIST prEN ISO 19694-5:2014
TC 264 WI 00264146:2014 (E)
 Preparation or processing of fuels in own installations.
6.2 Operational boundaries
Operational boundaries define the types of sources of emissions covered by this standard.
6.2.1 Scopes of emissions to be included
The requirements for including scopes of emissions in prEN xx “Stationary source emissions — Determination
of Greenhouse Gas (GHG) emissions in energy intensive industries — Part 1: General aspects” shall be
applied.
Subject to the limitations set out in section 6.3 below, the following GHG emissions sources shall be
measured for lime manufacturing plantsfacilities:
 All Scope 1 (direct) GHG emissions
 All Scope 2 (indirect) GHG emissions from the generation of purchased electricity
 Scope 3 (other indirect) GHG emissions from the production and transportation of imported kiln stone.
Each lime plant shall undertake an assessment of its Scope 1, Scope 2 and, where relevant, Scope 3 GHG
emission sources. The assessment shall include GHG emissions from all stages of the lime manufacturing
process undertaken at the plant including kiln stone preparation, calcination and downstream processing of
the lime products into ground lime or hydrated lime. Where kiln stone is imported into the site, GHG emissions
from its production shall be included.
By way of example, but not restricted to, the following GHG emissions as shown in Table 1 are relevant for a
typical lime manufacturing plant:
Table 1 — Relevant GHG emissions for a lime manufacturing plant
Scope Process steps
Direct emissions including extraction, quarry operations, transport to stone processing
Scope 1
plant, processing (washing, crushing, screening), transport to the lime kiln
Indirect emissions including extraction, quarry operations including quarry dewatering,
Kiln stone Scope 2 transport to stone processing plant, processing (washing, crushing, screening),
preparation
transport to the lime kiln
Includes imported kiln stone extraction, quarry operations including quarry dewatering,
Scope 3 transport to stone processing plant, processing (washing, crushing, screening),
transport to the lime kiln
Direct emissions from the manufacture of lime
Scope 1 Direct emissions from the production of LKD
Kiln Process
Direct emissions from the combustion of fossil fuels
Scope 2 Indirect emissions from kiln operation and infrastructure
Scope 1 Includes transport to silos, grinding/milling, hydrating or packing
Downstream
Processing
Scope 2
Includes transport to silos, grinding/milling, hydrating or packing

It is not necessary to include the following GHG emissions as these are deemed to be insignificant or out of
scope:
 GHG emissions from overburden removal in the quarry,
 GHG emissions from the rehabilitation or restoration of the quarry and plant,
