GreenLine
GreenLine is the term selected by EMS-GRIVORY for its new range of partially to fully bio based polyamide specialties. GreenLine products are based on castor oil derivatives, a fully renewable resource, and are therefore originated from a non food crop. 
A detailed Life Cycle Analysis conducted by EMS-GRIVORY shows that these products will contribute to a reduction of global warming thanks to a significant reduction of CO2 emissions, compared to traditional crude oil based polymers. Depending on the GreenLine product the reduction in total CO2 can exceed 70%, compared to crude oil based EMS-GRIVORY products exhibiting similar properties.
The castor oil plant of the family of the Euphorbiaceae (Ricinus Communis) is a robust annual plant mainly grown in semi-arid areas and poor soil in India, China and Brazil.
Until today GreenLine compounds have been developed in several product families, based on partially to fully bio based raw polyamides. The primary aim of EMS-GRIVORY is to offer bio based high performance polymers with properties equivalent or superior to those of products based on fossil resources.
GreenLine products are based on natural resources. However, they are not biodegradable.
