The new grade, BioSphere 203, has been developed specifically for use in blow moulded PET applications and maintains the clarity of the PET, rather than showing a haze, as is the case with the general purpose 201 grade.
BioSphere 203 is being particularly targeted at blow moulded bottles which will contain substances that would be incompatible with recycling.
BioSphere biodegradable plastic additive is a unique, easy to use, additive scientifically proven to accelerate the rate of biodegradation of polymers.
Unlike other products on the market, BioSphere does not need any industrial composting and can be added to almost all conventional polymers.
BioSphere additive does not change the physical properties of the part, enabling products to maintain shelf life and tensile strength, whilst benefiting from much enhanced biodegradation.
It remains unaffected by exposure to UV and does not prevent plastics entering conventional recycling processes.

Biosphere additive is food safe and has been tested to several international standards, including ISO 14021:2016, ISO DIS 15985 and EU Directive 84/62/EC, as well as several ASTM standards for anaerobic systems and aerobic systems.
The increased hydrophilicity allows acids, secreted naturally by microbes, to soften the macromolecules/bonds within plastic.
They are then able to consume the macromolecules much more quickly, accelerating the biodegradation process so much that degradation occurs up to 200 times more quickly.
As with all biodegradation there are biproducts from the process.
These are CH4, CO2, biomass, and water which is the same as with any other organic matter.
