Ostfold Research has included emission factors
for some groups of emissions (VOC, NMVOC,
alkenes, aromatics and esters). The calculations
are made according to the LCA-guide from the
University of Leiden (Universiteit Leiden, 2005).
The last update is from 26/4-05.

The global warming potential is based on a time horizon of 100 years. Gases have different lifetimes in the
atmosphere, and hence models have been developed for different time horizons. A time horizon of 100
years is most commonly used.

2 GOAL, SYSTEM BOUNDARIES AND DATA
2.1 GOAL OF THE ANALYSIS
2.2 FUNCTIONAL UNIT
The functional unit is 1 tonne product for cellulose, lignin and vanillin and 1 m3 product for
ethanol8
2.3 SYSTEM DESCRIPTION AND SYSTEM BOUNDARIES
7
8
The product is called ’Ethanol (99%)’, the actual ethanol content is 99,9%.
The analysis is performed on a ’dry basis’, meaning that the analysis is done per tonne dry matter (DM) of
the products. For ethanol this means that the environmental impacts are distributed only on the amount of
ethanol in the product (water contents are 0,1% and 4%).

HOW TO READ THE LCA NETWORK FIGURE
The figure underneath is an illustration and has nothing to do with Borregaard. The figure
shows the global warming potential for production of 1 kg of mineral wool (ETH-ESU 96
database, 2007). The figures use the Norwegian decimal system.
The total global warming potential for producing 1 kg
mineral wool is 1,59 kg CO2 -eqv. The raw material
contribution is 0,6639 kg CO2 -eqv. (see below). The rest
is due to emissions in the production process itself.
The width of the arrows
illustrate the environmental
burden connected to each
process/material.
The raw materials for producing
mineral wool are: coal cokes,
electricity, phenol and cement.
The global warming potential
connected to the raw material input
for mineral wool are: 0,082 + 0,197 +
0,0699 + 0,315 = 0,6639 kg CO2 -eqv.

APPENDIX 5:
LCA – WHAT, WHY AND HOW?
Author: Cecilia Askham Nyland, Østfoldforskning
What is a Life Cycle Assessment (LCA) ?
"A process that evaluates the environmental burdens associated with a product
system or activity." This is done by identifying and describing the energy and
material uses and releases into the environment. An LCA includes the entire life
cycle of the product, from raw material extraction, through materials
processing, use and disposal at the end of the product's life (from "cradle to
grave"). All transportation steps involved are also considered. LCA assesses the
environmental impacts of the system in the areas of ecological systems, human
health and resource depletion. It does not address economic or social effects.
Why Life Cycle Assessments?
Life cycle assessments give a more holistic approach to environmental aspects of
products. They can help the producer understand much more about what
environmental problems are associated with a product. The producer can also see
where in the product life cycle the main environmental burdens arise. This is
very useful information when deciding where to target resources for
environmental improvements, so that the resources will be used most
effectively.
60
Ostfold Research
There are many more uses for LCA, including analysing the results of future
changes in production, or raw materials suppliers etc. A short summary of the
main applications is given below:
Knowledge development
What are the most important environmental problems and where in the life
cycle do these arise?
What happens to our environmental profile if we make changes in our
production process?
Decision support
Where are the most effective areas for us to target resources (personnel,
technology, education) to improve our performance?
What sort of product/marketing profile do we want?
Which materials and suppliers should we use?
Information exchange/ communication
Information for employees (internal stakeholders), education as well as key
environmental data (EPIs) and environmental product information (EPDs).
Communication of the effects of a company's environmental improvement
efforts to authorities, neighbours, finiancial institutions and external
stakeholders (EPIs)
The phases of an LCA
According to the ISO 14040 standard, life cycle assessments shall include:
1.
2.
3.
4.
Goal and scope
Inventory analysis
Impact assessment
Interpretation of results
Goal and Scope
61
Ostfold Research
The goal of an LCA study should state the intended application, the reasons for
carrying out the study and the intended audience, i.e. to whom the results of the
study are intended to be communicated.
When defining the scope of an LCA study, the following items should be
considered, clearly described and justified:
-
The functions of the product system, or, in the case of comparative
studies, the systems
The functional unit
The product system to be studied
The product system boundaries
Allocation procedures
The types of impacts and the methodology of impact assessment and
subsequent interpretation to be used
Data requirements
Assumptions
Limitations
The initial data quality requirements
The type of critical review, if any
The type and format of the report required for the study
Functional Unit
The functional unit represents a product's performance according to a specific
user's requirements. This unit should reflect the product's function and life
span. Here is an example of a functional unit for cement and concrete:
1 km road, maintained and used over a 50
year lifetime
It is important that 'used' is included, as it is nescessary to include other
important aspects in the life cycle of the road. These are things like lighting,
noise muffling, road markings etc.
62
Ostfold Research
In an LCA, all mass and energy flows are normalised according to the functional
unit. Therefore all results are usually presented for the functional unit chosen.
System Boundaries
System boundaries must be defined, so that we can collect the right inventory
data. When one sets system boundaries one defines to what level of detail the
product system will be studied and which releases to the environment will be
evaluated. It is important that decisions to omit life cycle stages, processes or
data are clearly stated and justified.
Available inventory data can also set limitations to data gathering (for example
when only industry average data is available rather than site specific). Again
these limitations must be clearly stated and taken into consideration when
conclusions are drawn from the LCA study.
In order to help define system boundaries a product tree (or a product network)
is drawn. This product tree should include all life cycle stages and unit processes
involved, including transportation. The functional unit is the basis for which the
product tree is drawn.
When defining the system boundaries one must be practical, otherwise the level
of detail can be enormous. A common approach is to define cut-off criteria, for
example that all components that contribute less than 1% of the total mass flow
for the product system are not included.
Other important system boundaries that should be clearly stated are
geographical boundaries (e.g. is the study of a local, national, or international
nature) and time (e.g. what is the reference year for which the data is
collected). The intended application of the study, the assumptions made, cut-off
criteria, data and cost constraints and the intended audience all affect the
system boundaries. This makes it important that these aspects are documented
clearly.
63
Ostfold Research
Allocation procedures
Allocation is the partitioning of the input or output flows of a unit process to
the product system under study. Allocation is needed when a unit process in a
product’s life cycle has more than one product or raw material, which is part of
another life cycle. This means that it is not correct to allocate all environmental
burdens from the unit process to just one of the products.
There are several possible methods that can be used for allocation. The two
methods that are most commonly used are mass allocation and economic
allocation, but others such as volume and energy-based allocations can be used
where appropriate.
Mass allocation
Mass allocation is based on the mass flows
through the unit process and is illustrated in
the diagram above. The percentage (X) of a
given flow (M), contributing to a given product
(P), through a given unit (U) has been
calculated. This same percentage (X) is then
used as the percentage of the environmental
burdens (B) arising from the unit which are allocated to the product (P). Thus, if
a product uses 37% of the mass flow, it's also assigned 37% of the
environmental burdens.
Economic allocation
Economic allocation is based on the sales
price of the products produced and is
illustrated in the diagram above. Products P,
Q and R are produced from the unit process
(U). Their sales prices are p, q and r
respectively. Product P is therefore
allocated the fraction p/(p+q+r) of the
environmental burdens (B) arising from the
process unit. Thus, if the sales price of product Q is 40% of the total sales
price, it's assigned 40% of the environmental burdens.
64
Ostfold Research
Assumptions
It is important for the interpretation and use of the results from an LCA that
all assumptions are clearly documented. The assumptions and system boundaries
used affect the applicability of the results.
The assumptions used can be tested to see whether changing these assumptions
within reasonable intervals can change the conclusions of the study. This is
known as a sensitivity analysis and enables the LCA practitioner to gain an
understanding of the robustness of the conclusions from the particular study.
Limitations
There are also only a certain number of environmental burdens examined in an
LCA study. This means that although LCA is described as a holistic approach it is
also limited to the particular environmental burdens described in the scope
definition for the study.
LCA assesses the environmental impacts of the system in the areas of ecological
systems, human health and resource depletion. It does not address economic, or
social effects.
Inventory Analysis
Inventory analysis is the step where all material and energy flows in and out of
the product life cycle are quantified. It involves data collection and calculation
procedures to quantify the relevant inputs and outputs of a product system.
Thus inventory analysis aims to quantify all energy and raw material
requirements, emissions to air, discharges to water, solid waste and other
releases for each process step of a product system.
65
Ostfold Research
All inputs and outputs to the product system are related to a functional unit,
which is the basis for the calculations performed. For example we don't make an
inventory of what emissions and resource use are associated with a tonne of
concrete, but for the amount of concrete required for the maintenance and use
of a 1 km stretch of road over a 50 year lifetime.
When the inventory analysis is complete you have the life cycle inventory (LCI)
data.
Impact Assessment
Different environmental problems occur as a result of the
fact that we extract and process raw materials to produce
different products. Different emissions contribute to
different environmental problems (environmental impacts)
in different ways.
The impact assessment part of an LCA is where the
potential impacts of a life cycle are assessed. The results
of the inventory analysis (LCI) are used as the basis for
this. The impact assessment is formally described as
including the three phases shown in the figure to the left.
66
Ostfold Research
Classification - "Which emissions contribute to which impact categories?"
In the classification step, the
different emissions and energy
demands are assigned to different
impact categories based on the
expected kind of impacts on the
environment. The main purpose of
the activity is to describe which
potential environmental effects
the inputs and outputs may cause.
Characterisation - "How much do they contribute?"
In the characterisation step, the
potential contributions from the
different inputs and outputs are
connected to the different impact
categories, and the contributions to
the same impact category are added
up. Different emissions contribute
differently to a given impact category,
e.g. methane (CH4) contributes 21 times more to global warming potential than
carbon dioxide (CO2).
Weighting - " Which impacts are most important?"
The weighting phase is an optional phase
(ISO 14043, 1999) where the results for
each impact category are weighted into an
overall quantitative statement of the
potential environmental impact for the
product system.
Interpretation
67
Ostfold Research
In this phase of an LCA one analyses results, reaches conclusions, explains
limitations and makes recommendations. It is important that one considers
carefully the goal and scope of the study during this phase. Interpretation of
the results of an LCA must be done according to the Goal and Scope of the
study in order to be of value in decision-making.
A good example of this is if data gaps in the inventory phase are shown to be
important for the outcome of the study, one recommendation would be to repeat
the LCA calculations and fill in the most important data gaps.
