Mater-Bi
Mater-Bi is a starch blend based on corn starch , which is classified as a biodegradable material (BAW) and is processed using the usual plastic processing methods.
properties
Mater-Bi is the brand name for a starch blend from the Italian company Novamont SpA . It is a bio-based and biodegradable plastic from which the first biodegradable garbage bags in Germany were made in 1992.
Mater-Bi is based on more than 85% corn starch. It is compostable, GMO-free, lead-free, water-soluble, can be burned without leaving any residues and can be recycled several times if it is properly separated. Mater-Bi is also suitable for dimensionally stable and foamed products. Mater-Bi mulch films and papers are a certified ecological product and compost 100% within 10 to 12 weeks. They are used successfully in organic vegetable growing, in nurseries and tree nurseries.
A development cooperation between Goodyear and Novamont has been running since 2005 on the use of Mater-Bi as an additive for rubber in tire production. Initial results show better grip properties than traditional fillers such as carbon black and silica with a simultaneous reduction in rolling resistance.
Environmental certificates
The biodegradability of the Mater-Bi materials has been certified by various organizations (DIN Certco, Berlin; AIB-Vincotte, Belgium; Istituto Italiano Plastici, Italy) in accordance with the applicable standards (DIN V 54900, EN 13432, UNI 10785). The ecotoxicological harmlessness for animals and plants has been tested and certified by OWS as part of the OK Compost test program (Compost Home and OK Biodegradable).
