Environment and Waste
Plastic containers are actively came into our lives twenty years ago. Today we can not imagine a different packaging for water, beverages, various dairy and meat products. Plastic fairly durable, lightweight, easy to use. However, few people think about the harm they cause to the environment.
Polymers virtually decompose, they persist for a hundred years or more. Can you imagine what legacy we leave to future generations?
To protect themselves from impending disaster, it is necessary to organize in cities and other populated areas receiving plastic . You can certainly dispose of packaging, but stand out enough harmful substances that pollute the atmosphere even more, cause cancer and affect the environment.
Experts estimate that in the year people throw in the trash can about 250 kg of household waste. Of these, only a quarter of food waste accounts for up to ten percent – is all kinds of paper and cardboard, and almost 50 percent – plastic products. Here, except for packaging includes household items that have become unusable: cans, basins, disposable tableware, plastic bags. Also at these points can be made and buying recycled paper . The more of these points, the clearer will be our streets and safer life.
Polymer processing can be done in two ways: chemical and mechanical. Chemical implies sophisticated equipment, expensive catalysts and professionals. For these reasons, this method has not been widely used in our country.
But the mechanical recycling can be expensive and quite a lucrative business for various companies. It includes the initial sorting and crushing waste, agglomeration and granulation. For its development is necessary to organize the continued availability of raw materials for the revisions. That is why today offers a variety of items to receive plastics and other polymers.
First bottles are cleaned of debris and labels, sorted by color and type of plastic. This is carried on the belt, with the participation of several workers. Sort the material is sent to the crusher. There he crushed to crumbs, which is then washed and dried. In this case, instead of water, a solution of acoustic soda, and drying is carried out at 130 degrees.
After that, the dried lumps turned into pellets of a certain size. In the future, a secondary raw material used for production of various products.
