A person encounters polyethylene almost every day. LDPE waste also accumulates in enterprises. After using the products, they can be thrown away, destroyed, but this is considered an irrational decision. The material decays for a long time. Unnecessary products can be returned, receiving money for this. After admission, the companies process the raw materials with the further receipt of new goods for everyday use.
Recycling
Thanks to modern technology, LDPE waste is used for processing. After this, the raw materials are not inferior in properties to the primary material. Processing is due to the transformation of materials into granules. The procedure includes several stages:
- Collection.
- Sorting.
- Cleaning up.
- Agglomeration.
- Secondary cleaning and drying.
- Granulation.
Only with these actions will you be able to create quality products. Each stage in the enterprise is controlled by specialists. After processing, raw materials can be used to produce new products or serve in the manufacture of materials similar to primary materials. The collection of LDPE waste is carried out by private companies that process it. This procedure protects the environment from the harmful effects of waste products.
Sorting
It is important that the waste of the LDPE film is uniform. Efficiency of processing depends on sunlight, chemicals, moisture, traces of operation. For materials with different characteristics, a different technological approach is used.
Waste is packaging bags, color films and other materials. As a result of processing, the same products are usually obtained. It is assumed that due to the short life of the material was not exposed to negative factors, therefore, could not change its properties.
But there is a waste of LDPE with a restructured structure. Then they are suitable for obtaining solid materials due to mixing with additional substances, for example, with sawdust. And only in rare cases are they used in their pure form. This polyethylene is processed using agglomeration, that is, the breakdown of the product into polymers. Such material is used for agricultural purposes, the manufacture of buckets, barrels, and other products.
The use of secondary LDPE
Recycled LDPE waste is used to make plastic. The cost of such material will be lower. It is more profitable to create secondary LDPE for industry, manufacturing containers for special chemical components, household films.
A promising area is the manufacture of products using fillers and additives. Also in their composition may be composite materials that replace wood and metals. Their combination allows you to get various products.
Many organizations process raw materials, so they need unnecessary polyethylene. Some of them work with processing industries. This allows you to dispose of waste, as well as get a good income. In addition, such products are not harmful to nature.
LDPE Properties
The main property of LDPE products is strength. Moreover, it persists after processing. Also, the finished product has other characteristics:
- flexibility;
- elasticity;
- resistance to chemical components;
- resistance to temperatures and ultraviolet.
After processing, the waste is used for the manufacture of bottles, containers, containers, packaging film, liners, coils. Raw materials are used in the production of fillers for electrical components, as well as for the manufacture of garden plastic furniture.
It is necessary to recycle garbage, since the production of these products has low costs. For excellent results, careful sorting is necessary. It should be noted that the price of raw materials is determined by purity and quality. Therefore, only the best products are used for processing, because it takes less time and cost.
