Abstract
A method of biodegrading polymeric products is disclosed, which provides for addition of brewer's yeast or yeast mother or a mix of the two in the polymers or compounds that form said polymeric products.
Claims7
1) Method of biodegrading final products obtained from compounds of thermoplastic polymers, wherein said thermoplastic polymers are polymers with hydrocarbon chain with double carbon bond (—C═C—) and/or single carbon bond (—C—C—), modified with plasticizer additives of mineral type, such as paraffin mineral oils,
- method comprising the following steps:
- addition of brewer's yeast or yeast mother or a mix of the two to said compound of thermoplastic polymers to obtain a final product containing brewer's yeast or yeast mother or a mix of the two, and
- biodegradation of said final product in a composting installation.
