Process for producing a carbon dioxide neutral and biodegradable polymer and packaging products produced thereof

A process for producing a polymer material comprising the following steps:

• (a) providing a polymer material, wherein the polymer material is carbon dioxide neutral, and in the form of polyethylene made from sugar cane ethanol,
• (b) providing a biodegradable additive,
• (c) blending the polymer material of step (a) with the biodegradable additive of step (b), wherein the blending ratio of polymer material of step (a) to biodegradable additive of step (b) is 90-98 wt. % of the polymer material to 10-2 wt. % of the biodegradable additive, and the amounts sum up to 100% wt., wherein the biodegradable additive of step (b) is an organic mixture for the growing of naturally occurring organisms comprising a fungal-bacterial mixture on said polyethylene, wherein the fungal-bacterial mixture produces enzymes and acids for effecting enzymatic catalysis.
