The project is about the PET plastics and PET recycling. This is a process of recycling plastics that are recyclable from the environment. PET is a thermoplastic polymer resin belonging to the polyester family. It is basically used in the manufacture of synthetic fibres, food and beverage liquid containers. Other uses include the thermoforming applications and the engineering resins where it is often mixed with glass fibre.
On the methodology, research has shown that mixing starch with plastic will lower degradation, but it still doesn't lead to complete breakdown of the plastic. Bacteria have been genetically engineered to synthesize a completely biodegradable plastic, but this material is expensive at present.
Recycling of plastics reduces the trash deposited in landfills, and offers the opportunity for consumers to clean and reuse containers for everything from water spritzer bottles to holding excess amounts of shampoos, cleaning fluids or lotions. Recycling all plastic bottles that contain PET or HDPE labels somewhere on the bottle, most often found on the neck of the bottle to make separation of recyclable and non-recyclable plastic easier on consumers is a better remedy.

In 2005, 2 million tons of plastic bottles in the United States ended up in the trash instead of in recycling bins. The State container deposit law which is known as "bottle bills" are long overdue for an upgrade. They have proven to be the most effective approach to collecting bottles and cans. Currently, only 11 states have bottle bills in America.
Plastics are indeed everywhere, from the grocery to the shopping mall. They are important in the packaging industry, but a closer look at the plastics brings into focus the price to be paid by using and dumping it the wrong way. This therefore calls for a lot of care. Before you toss that plastic bag to the environment then be sure of the impact you are creating. Plastics are very durable and this means that they will degrade very slowly therefore takes long in the environment. Decomposition by burning also creates serious toxic fumes in the atmosphere. The production as ...
