Biodegradable polymer composition

Biodegradable polymer masterbatch additive that turns polyethylene, polypropylene, and PVC blends into compostable-like plastics.

What it is

The technology combines polyethylene/PP/PS/PVC blends with cellulose, amides, nutrients from blue-green algae and/or yeast, plus water to form a biodegradable additive that can be compounded as a masterbatch into virgin polymers. It’s technically significant because it targets common commodity plastics (e.g., PE/PP/PS/PVC) with a formulation that includes a biologically driven nutrient package rather than relying only on specialty resins. Previously, commercial use required licensing or permission from the patent holder to compound and sell products like carrier bags, garbage bags, and packaging films using this specific additive approach.

What you could build

Launch compostable-style garbage bags and packaging films by compounding the patented biodegradable masterbatch into commodity resins.

Original abstract

A novel biodegradable additive polymer composition useful for the preparation of biodegradable plastic products which comprises a mixture of polyethylene, polypropylene, polystyrene, polyvinyl chloride or a mixture thereof, cellulose, amides, nutrients selected from blue green algae and/or yeast, and water. The composition can be mixed with a virgin polymer to get a master polymer, which is useful for preparing biodegradable products such as carrier bags, garbage disposal bags, hospital disposables, packaging film and thermoformed plastics.
