The acronym HDPE (high density polyethylene) is often used to refer to type 2 plastic. HDPE plastic is often used to make bottles for beverages with short shelf life, such as milk and juice. Because HDPE has good chemical resistance, it is also often used for containing household and industrial chemicals such as detergents and bleach. HDPE is also used to manufacture grocery and retain bags. HDPE plastic can be recycled into bottles for holding household chemicals such as detergent, shampoo, conditioner and even motor oil. Recycled HDPE plastic can also be made into pipes, buckets and bins, pens, flower pots, film and sheets, benches.

Type 1 Plastic
Type 1 Plastic – Polyethylene Terephthalate (PET, PETE)
Type 1 is PET and PETE or polyethylene. Such types of plastics are commonly used in water bottles. The acronym PETE (polyethylene terephthlate) or PET (poly ethylene terephthalate) are often used interchangeably, to refer to type 1 plastic. PET or PETE plastics are often used in soft drink bottles, as well as food and non-food containers, because of their good gas and moisture barrier properties. PET and PETE plastic can be recycled into carpet yarns, fiberfill, tote bags, food and drink containers, luggage and clothing.

Type of Plastics
Types Of Plastics
- Type 1 is PET and PETE or polyethylene. Such type of plastics are commonly used in water bottles.
- Type 2 is HDPE or high density polyethylene. Commonly used in trash and shopping bags. Also in the milk jugs.
- Type 3 is PVC or polyvinylchloride. PVC piping is the most common form of this plastic type.
- Type 4 is LDPE or low density polyethylene. This type is used in the packaging of frozen food.
- Type 5 is polypropylene of PP. Tupperware, disposable cups, etc. are some examples of polypropylene.
- Type 6 is PS or polystyrene. These plastics are use in egg cartons and packing peanuts.

Recycling Plastic Bags
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).
