THE BASIC METHOD
The basic method employed is to create an enzyme that would attract carbon eating bacteria and enable them greater direct access to the carbon elements within the polymer chains. In this way the biodegrading of the polymers is accelerated whereby polymers dissolve rather than fragment.
This process created by microorganisms does not occur on the shelf, nor does it occur when water is in contact with the plastic. This reaction of microorganisms only occurs when the product is placed in an active microbial environment. The additive attracts over 600 different types of microbes to consume the polymer. The enzymes that the microbes produce react with the additive creating a catalyst that breaks down the molecular weight of the polymer making it easier for microorganisms to consume the plastic.
This is called biodegredation.
CURRENT BIODEGRADATION MODELS
- No Organic Additive, Aerobic Biodegradation only.
- With additive plastics require full sunlight and exposure to UV.
- Will not degrade in landfill unless fully exposed.
- No Organic Additive, Aerobic Biodegradation only.
- With supplement, plastic requires high heat and increased humidity to be applied mechanically to landfill. Additive typically added at higher percentage dosing in resins.
- Requires high levels of oxygen for biodegradation.
- Will not degrade in landfill.
- With Organic Additive, both Aerobic and Anaerobic Biodegradation.
- Biodegradation under standard landfill conditions – not dependant on heat or humidity – is accelerated under above conditions with incremental microbe activity.
- Supplement increases biodegredation 100 – 200 times faster than regular plastic products.
- 60% biodegradation within 12 months.
- 100% biodegradation within 60 months.
CYCLE OF DEGRADATION: PLASTIC VS. ORGANIC ADDITIVE
The problem with plastic is that it never truly disappears. The materials simply break down, over a long period of time, into micro-plastic particles that harm marine and animal life, contaminate water systems and cause soil erosion.
REGULAR PLASTIC WITH ADDITIVE
After a product infused with the Organic Additive enters a microbe rich environment, the microbes will begin to break down the molecules of the product until the end result is a microbial biomass, H20, CO2.
The amazing benefit of the Organic Additive is that it converts the plastic product (which is very slow at biodegradation) and turns it into a biodegradable product that shows biodegradation 100 – 200 times faster than regular plastic products.
Anaerobic Degradation is the breakdown of plastic products without the presence of Oxygen. After Anaerobic Degradation of the Organic Additive Products, the end result is a mixture of CH4 (Methane), CO2 (Carbon Dioxide), Biomass, and water.
Aerobic Degradation is the breakdown of plastic products with the presence of Oxygen. After Aerobic Degradation of the Organic Additive Products, the end result is a mixture of CO2, Biomass, and water.
BIODEGRADATION IN LANDFILLS
The first phased of Biodegradation with the Organic Additive consists of the larger Polymers being broken down at the molecular level by exposure to water, oxygen and heat. Thereafter it is reduced to smaller Oligomers, Dimers and Monomers molecules.
The second phase of Biodegradation with the Organic Additive consists of the now smaller molecules being digested and broken down by Microbial Organisms, metabolised and converted to Microbial Biomass, CO2 (Carbon Dioxide), CH4 (Methane Gas) and water.
