Life Cycle Assessment

Life-cycle assessment (LCA), also known as life-cycle analysis, is a standardised method used to assess the environmental impacts associated with all the stages of a product's life from cradle to grave (i.e., from raw material extraction through materials processing, manufacture, distribution, use, repair and maintenance, and disposal or recycling).

Benchmarking

Sika Liquid Plastics are an industry leader with a pioneering portfolio of sustainable products, systems and services that are designed to be efficient in energy, material and water use. Therefore all new product developments are benchmarked via LCA against existing products in the Sika portfolio and the competition to ensure that they meet our stringent sustainability expectations.

Project Specific LCA Reports

Sika Liquid Plastics can now offer summary LCA reports for individual projects. The LCA is performed by the Corporate Product Sustainability team, modelled in the GaB1 6.3 Software and carried out according to the ISO 14040 series and EN 15804.

 

As a standard approach, Sika evaluates all impact categories and resource indicators deemed as important according to the relevant standards - for Roofing Cumulative Energy Demand (CED) and Global Warming Potential (GWP) are considered to be most relevant. Others, such as Use of Net Fresh Water are less significant for roofing and hence not included in this.

 

This simplified approach enables the differentiation of roofing systems that may have similar physical performance, but greater differences in their environmental impacts.
