Page 67 Compostable plastic is plastic that is capable of undergoing biological decomposition in a compost site, such that the plastic is not visually distinguishable & break down to carbon dioxide, water, inorganic compound and biomass at a role consistent with known compostable materials. polymers, polypropylene, polylactate, polycaprolactone, polyesteramides, polybutylene, adipate cateraphthalate. A growing portion of these plastics now have renewable origin, rather than petrochemical for biodegradable plastic is 3.5 lac tons compared to 280 million tons of petrochemical plastics. Although widespread use because of high cost. more expensive to produce than waste treatments. Type of Plastics Not all types of plastic is born equal. Each plastic are reusable and other aren’t because of chemicals they contain, some can be recycled & others need to be In 1988, the Society of the Plastics Industry (RIC) system which divided plastic resins 1. PET - Plastic that belong to group number one are made out of polyethylene terephthalate or PET. It is mostly used for food & drink packaging purpose due to its strong ability to prevent oxygen from getting in and spoiling the product inside. 2. HDPE - High Density Polyethylene - It's an incredible resin used for grocery bags, milk jugs, recycling bins, agricultural pipes, playground equipment, lids and shampoo bottles long unbranched polymer chains it is much stronger & thicker then PET. 3. PVC - Polyvinyl Chloride is the world's third most widely produced synthetic plastic polymer. It come in two basic PVC is largely used in the building & construction industry to produce door mixed with the substance, it can be applied to plumbing, wiring and 4. LDPE – Low Density Polythene is characterized by low density molecules, giving this resin a thinner simplest structure of all plastics, making it easy and cheap to produce. Used in plastic bags, various containers, dispensing bottles and plastic wraps. 5. PP - Polypropylene is the second most widely produced commodity plastic and it's market is forecasted to grow more in upcoming years. It can withstand high temperature and is found in Tupperware, Car parts, Thermal, yogurt containers and disposal dippers. 6. PS - Polystyrene can be solid or foamed. It is very inexpensive resin per unit weight & easy to create. It is can be found in beverage cups, insulation packaging materials, egg cartoons and disposable dinner ware. Environmentally, speaking it’s among the worst types of plastic as is not biodegradable, animals also recognize on health of birds or marine animals
