Plastic bags are huge factor in unstable environment; but at the same time plastic bags are in used globally on a large scale for various purposes. They are manufactured from the low density polythene which is a non-biodegradable product. Although they can be degraded through photodegradation, the process involves release of small toxic products which are hazardous to the environment. Improper disposal of polythene bags and its non-biodegradable nature, thus, makes plastic a threat for the environment. When these plastic bags are deposited on the ground, it results in clog landfills. It is because of its inability to degrade plastic bags. Plastic bags when accumulated on water can become harmful to the marine life. So for all these reasons and many more recycling of plastic bags is mandatory. Recycling can also saves a lot of energy, as the process of manufacturing plastic bags demands a huge amount of energy. The process of recycling consumes 20%- 40% lesser energy for the production of new products. So it is win-win situation for everyone.
In addition to reducing the amount of plastics waste requiring disposal, recycling plastic can have several other advantages:
1. Conservation of non-renewable fossil fuels - Plastic production uses 8% of the world's oil production, 4% as feedstock and 4% during manufacture.
2. Reduced consumption of energy.
3. Reduced amounts of solid waste going to landfill.
Reduced emissions of carbon-dioxide (CO2), nitrogen-oxide (NO) and sulphur-dioxide (SO2).
