Use advice for data set This LCA is a Cradle-to-Grave with options. All major steps, from the extraction of natural resources to the final disposal
of the product, are included in the scope of the study. The life cycle stages included are A1-A5, C2 and C4 and D. The use
stage, B, is not considered in this study, since no impact are associated with the use stage. C1 and C3 are excluded,
because there are no dismantling or demolition activities and no waste processing steps respectively. All impacts
associated with the upstream production of materials and energy are included in the system boundaries. Mining activities
and controlled landfills are included in the product systems. Wastewater treatment is not considered within the
technological systems since it is already included in the solid waste treatment processes. The emissions and resource
extractions derived from these processes are considered elementary exchanges between the product systems and the
environment.
Paint products do not consume resources and are not released into the environment during the use phase. Moreover,
painted surfaces do not require maintenance, repair, replacement or refurbishment beyond their normal use, so no impact
is considered for modules B1 to B7 and therefore excluded in this assessment.
Regarding the end-of-life stage, the waste processing stage (C3) is irrelevant as no further processing is required during
the end-of-life of decorative paints since they are disposed together with the substrate where they are applied on and not
reused or recycled. Since the efficiency rate cannot be considered higher than 60% it is not included in this assessment.
Module D is included to show the benefits and loads beyond the system boundary from the net output of recovered energy
from the product system. Energy recovery values for the paint waste are taken on the default level in PEFCR for decorative
paints: 1.01 MJ of electricity and 2.16 MJ of heat per kg of waste. Energy recovery values for the packaging materials
waste are taken from the background documentation of the respective Ecoinvent datasets.
The allocation is made in accordance with EN15804:A2. Allocation is based on physical and production shares. Energy
and water use are allocated according to production volume. |
