Our scientists have created a proprietary formulation for plastics that makes it possible.
How it works
- Achieving full biodegradation without harming recycling and enabling the circular economy
During the service life of the packaging, the technology is dormant.
The packaging retains all its functionalities.
Adjustable onset to support the circular economy and to give recycling every chance to happen where available.
- Phase 1 – Product service life determination:
Accelerated thermal aging as per ISO 2578 / ASTM D3045.
Arrhenius equation used to estimate service life depending on average temperature of geographical territory/territories of interest.
Tested against RecyClass Recyclability Evaluation Protocol showing no adverse impact to recycling.
Upon activation of the technology, the chemical conversion causes a rapid loss of physical properties.
Greater surface area exposed during this process aids greater chemical transformation towards a bioavailable wax.
The technology attacks the crystalline and amorphous region of the polymer structure, rapidly turning it into a wax-like material that is no longer a plastic and is not harmful to the environment.
- Phase 2 – Weathering
UV (film) or Xenon-arc (rigid) of plastic products for a defined short period of time representing (through calculation) to be no more than 4 months corresponding to South Florida conditions.
Standards used for UV weathering are ASTM D4329 / ISO 4892-3. Standards used for Xenon-arc weathering are ASTM D2565 / ISO 4892-2.
Stage Gate 1 – Criteria for attainment of a bioavailable wax:
Stage Gate 2 – Environmental Safety:
Bioavailable waxes formed as a result of the chemical conversion are tested for their biosecurity in multiple types of environmental ecosystems.
The waxes are tested for their acute and chronic eco-toxicity in soil and water environments.
Proof that both polyethylene and polypropylene waxes are non-harmful to organisms in these habitats has been demonstrated through meeting the validity criteria of the following OECD tests:
If a wax is produced from a group of plastic resins or the resin contains additional pigments or components, for which we do not have valid testing data, we re-run selected OECD tests to ensure that the waxes are always environmentally non-harmful.
The bioavailable wax is biologically transformed through mineralization by naturally occurring bacteria and fungi in the natural environment and under mesophilic/ambient temperature conditions.
PE and PP films and rigids fully biodegrade within 1–2 years as verified by 3rdparty labs, leaving no microplastics behind.
Phase 3 –Biodegradation on soil under mesophilic conditions
The biodegradation testing is performed as per international standards of ASTM D5988 and ISO 17556.
The test, as with compostable plastics, shows the conversion of carbon in the test material (the bioavailable wax) to carbon in carbon dioxide.
Stage Gate 3 –Biodegradation:
The internationally accepted level required to show complete biodegradation is the attainment of a % biodegradation of greater than 90%.
The remaining material is converted to water and biomass.
How it is deployed
Formulated as a Bespoke Masterbatch.
Each Bespoke Masterbatch is tailored to the resin’s footprint, application profile and required use life. Compatible with the normal plastic conversion processes.
Typical loading rate: 2% weight percentage (wt%).
