Instead, a conventional non-biodegradable plastic (e.g. fossil-based PEPolyethylene, thermoplastic polymerised from ethylene. Can be made from renewable resources (sugar cane via bio-ethanol).

Microorganisms are supposed to consume these additives and the degradation process should then expand to the non-biodegradable PEPolyethylene, thermoplastic polymerised from ethylene.

After some time, the plastic is supposed to visually disappear and to be completely converted to carbon dioxide and water. This is a theoretical concept which has not been backed up by any verifiable proof so far.

As no proof for the degradation process has been provided, environmental beneficial effects are highly questionable.
