Biodegradable polymers are generally recognized as those which are designed to degrade through the action of living organisms. BIOTEC BAGS® with enzyme compounded polyethylene constitutes of enzymes, sodium salts and oxidation agents with LDPE / HDPE AND LLDPE is a highly cost effective and eco friendly non hazardous technology used primarily for making CARRY BAGS, GARBAGE BAGS, POLYETHELENE LINERS AND FILMS.
THE TECHNOLOGY – EVOLUTION
It is observed that world over there were certain process methodology /inventions /claims about the availability of starch/cellulose/lactic acid based compositions with polyethylene to make a degradable plastic. We found to our dismay that ‘Neither’ all of them or ‘None’ of them could effectively break down the polymer matrix and make the polyethylene completely biodegrade in the soil environment. Having decided to adopt a different road map to achieve a possible complete biodegradation of plastic film, we explored the possibility and process ability of enzyme and bacteria based substrate to effectively penetrate in to the polyethylene chain structure.
After having theoretically concluded that polyethylene can undergo a change in its chemical structure with enzyme in to it the inculcation of proteins and sodium salts along with a composting agent to enable the polymer particles to become a food for soil bacteria was seriously looked in to. We successfully narrowed down the enzyme, protein, bacteria compound drawn mainly from natural resources and medicinal plants to make this process methodology/technology non-hazardous and non-toxic. Our team successfully formulated the blending for an effective process module in the conventional processing machines that is film extrusions without recommending any modifications there to.
The clinical trials/tests initially revealed us polyethylene film undergoes a definite change under environmental conditions. Furthermore the enzyme bacteria composition enabled polyethylene film withstand the biodegradable norms as specified by world governing bodies enumerated in protocols to be classified as fully biodegradable plastic packaging materials due to the release of CO2 and water during and after the process of biodegradation in the soil environment.
HOW DOES THE TECHNOLOGY WORK?
ENZYME WITH POLYETHELENE
Enzyme used in this technology is regarded as a catalyst, helping to change of chemical reaction of polyethylene, accelerating its biodegradation process. Autotrophic bacterial presence in mineral salts medium containing some inorganic form of nitrogen energy supplying material is also used in this technology. The PH VALUE of this composition blended with polyethylene confirming its non acidity characteristics.
COMPOSTING OF POLYETHELENE
It is observed that soil contains at least 58 PERCENT CARBON. THE GREATER PART OF NITROGEN IN THE SOIL IN INTIMATELY ASSOCIATED WITH THE ORGANIC MATTER. As the soil organic matter gradually decomposes the organic nitrogen is converted into water soluble or available forms of ammonia and nitrates. This moisture soil reacts on the biodegradable polyethylene film making it susceptible to composting and release of Co2 during composting.
Biodegradation or Alternatively chain end degradation is achieved on plastic when ENZYMETIC characteristics follows the unzipping mechanism of polyethylene molecular chain ends, resulting in successive release of MONOMERIC units composting and release of CO2.
Our Enzyme Compound acts as an active center of high energy in cell surface caused by the interplay of affinities of neighboring molecules in polyethylene. The effective center enzo compound has exhorted a specific power of absorption on the polyethylene and activated it by distorting the electronic system rendering thus adsorbed molecule at polyethylene unstable and capable of undergoing a chemical and thermal change. The enzo compound with inhibited bacterial culture (bifida bacteria metabolism) contains macro molecules which exhort a bacterial mode action.
The Oxidation reduction systems in connection with bacterial metabolism inhibited in polyethylene through enzyme composition has resulted in enhancing the biodegradation process. This idea of oxidation naturally involves the exhortation of oxygen to the compound and a typical oxidation being such a reaction as the combustion of carbon to yield CO2.
Our enzyme compound is used in this technology as source for growth of bacterial culture. A definite bacterial group found alive and active under suspended mode in these bags with our enzyme compounded technology proves that the soil bacteria and the bacterial group present in the bag jointly eat away the polyethylene film leading it to total biodegradation. As bacterial count present will ensure active and further multiplication of bacteria in the presence of soil condition.
“All enzymes are protein … But all Proteins are not enzymes”
All the ingredients of our Enzyme Compound composition are ‘food grade and non-toxic’ in nature.
THE MYTH: The myth that the bacterial metabolism is inactive or dead at enhanced temperature is hither to prove wrong as bacteria remains in a state of suspended animation only. These bacteria once again become active after coming into contact with soil, atmosphere conditions and normal temperature.
