Biodegradable Plastic Additive

BioSphere biodegradable plastic additive is a unique, easy to use, additive package which rapidly enhances the ability of plastic to biodegrade when added to polymers and works in both anaerobic and aerobic systems.

BioSphere biodegradable plastic additive

Scientifically proven to break plastic products down completely and return them to nature in a short period of time BioSphere is the fastest acting biodegradable additive on the market today.

A 1% addition of Biosphere additive masterbatch can increase the rate of degradation of a plastic product by 100-200 times when compared to unmodified plastics and works in all major resin types including PET, PP, PS, and PE.

BioSphere additive will not change the physical properties of the plastic part enabling products to maintain their normal shelf life and tensile strength, whilst benefitting from enhanced biodegradation.

Food safe, Biosphere additives have been tested to, and comply with, several international standards including ASTM D5526 & ASTM D5511, for anaerobic systems, and ASTM D5338/ISO 17088 for aerobic systems.

How it works

Biodegradable additives enhance the biodegradability of plastic by increasing their level of hydrophilicity.

Traditional plastics are typically hydrophobic which allows for only a small amount of biodegradation to occur which means biodegradation takes a very long time.

Biosphere allows acids, secreted naturally by microbes, to soften the macromolecules within plastic. These microbes are then able to consume the macromolecules much more quickly resulting in much faster biodegradation occurring.

In anaerobic systems, such as landfills, the plastic is turned into CH4, CO2, biomass, and water.

In aerobic systems, such as compost facilities, CO2, biomass, and water are produced.

Definition of Biodegradable

Biodegradable means the total breakdown of a product (by microorganisms) to something found in nature.
