Evonik Polymer VS 500

Goal: Calculation of the environmental performance of products manufactured and sold by Business Line Interface & Performance

System Boundary: Cradle-to-Gate

Functional Unit (FU): 1 metric ton Polymer VS xxx

Methodology: All our Life Cycle Assessments are following the principles of ISO 14040/44 and ISO 14067 standards. The established method of the Dutch Environmental Science Research Center Leiden (CML) with characterization factors from November 2013 was used.

Data Sources: The LCA was created in 2015 by an internal Life Cycle Management team. The LCA is based on primary data from the year 2014 by Evonik for the production process, while secondary data from databases (such as GaBi and ecoinvent), suppliers or literature is utilized for external processes and raw materials. The software GaBi 10 was used for the LCA modeling.

Cut-off rules for the inventory: In general, 1% for single inputs and below 5% for the sum. No environmentally relevant flows were neglected. Some utilities of production processes have been modeled analog to known processes. Transports have been considered but distances have mainly been estimated. The result uncertainty in all categories is about ± 20% as these results base on several assumptions.

Results (Cradle-to-Gate):
