Some of the key segments of plastic recycling into oil market constitute several technologies such as thermal degradation, catalytic degradation and gratification. Pyrolysis is a thermal degradation process that takes place in absence of oxygen in a closed cylindrical chamber. The plastic is proselyted at 370 to 420 degree Celsius. In this process the volume of the waste can be reduced substantially and it is an economical process to convert plastic into oil. In the catalyst degradation process a suitable catalyst is used to carry out a cracking process. Presence of catalyst lowers the temperature and the time required for the reaction. Catalyst can be reused in the process that makes this process cost effective and reduce adverse environmental impacts. Gratification process is a thermos-chemical conversion of the solid carbon based molecules into a combustible product. Gratification process can be used as a substitute for the conventional processes to convert plastics into fuel such as incineration process. If you burn pure hydrocarbons, such as polypropylene (PP) and polyethylene (PE) it will produce a clean burning fuel. But burning large amounts of chlorine and PVC will damage the reactor and lead to environmental pollution. Polyethylene terephthalate (PETE) is best to recycle as it produce oxygen while burning into oxygen deprived chamber which leads to slowing the process.
Global plastic oil market can be divided into industrial and household waste on the basis of the manifold waste. Household waste consist of the emitted the waste by the household, however, it also contain the restaurants, household articles, bottles, and plastic packing cause the firm waste, Bottle be made from the single type of the plastic, it is easily to sort out and handle it, Household plastic waste is easily to process and produce the oil than industrial plastic waste , because it required sorting and cleaning relative to easily and cheaper.
China and Japan are some of the major countries in the Asia-Pacific region have begin the recycling process on the commercial level, Plastic waste was sent to many country ,like India, Australia and many others. North America, Latin America, Africa and China are the largest plastic waste producer in the world, Therefore, the region of development for the waste plastic into oil is more in these region,
Growing population and increasing of the energy demand are the main driver for plastic to oil market. Many governmental policies created for the plastic waste recycling in this market in recent years, Plastic waste recycling is required sort into different kind of plastics, so it is labor intensive which lead to the high cost, It can be the limited in the plastic oil market.However many machines are being developed that sorts with laser techniques and can differentiate between different types of plastic materials.
