6. LCA: Interpretation

The LCA results of Modules A1-A3 are interpreted in

the following.

After standardisation to overall German emissions, the

most relevant environmental impacts of the production

of wood fibre insulation materials (Modules A1-A3) are

the Global Warming Potential (GWP), the Acidification

Potential (AP) as well as the Photochemical Ozone

Creation Potential (POCP).

Global Warming Potential

72 % of the global warming-relevant gases can be

attributed to the production of the wood fibre insulation

materials on site (Module A3). With a share of 27 % of

total emissions, the provision of the raw materials and

preliminary products is also significant (Module A1).

Transportation to the factory location (Module A2)

contributes only 1 % to the global warming potential. In

the factory, the greenhouse gas balance is dominated

by the drying of the fibres and of the product (30 % of

total emissions in Modules A1-A3), the use of

resources (16 %) as well as electricity requirements for

fibre production (8.2 %).

Acidification Potential

82 % of the acidification potential (AP) results from the

production of the wood fibre insulation materials

(Module A3). 17 % is caused by the provision of the

raw materials and preliminary products (Module A1).

Transportation (Module A2) contributes only 1 % to the

AP. With 52 % of total emissions in the production

phase (Modules A1-3), the drying of the fibres and of

the pressed insulation material and with 7 % the
