Polyethylene is a type of plastic polymer obtained through the polymerization of a monomer called ethylene. Polyethylene waste encompasses various products used daily, such as packaging, bags, and bottles, which have been used and lost their properties. The natural decomposition of polyethylene is difficult and requires a long process. Therefore, the recycling of polyethylene waste is crucial.
In today’s world, where lifestyle habits compatible with sustainability principles are adopted, the recycling of polyethylene waste is critical. The recycling process of polyethylene waste can prevent the harm caused by plastic waste to the environment and human health.
What is Polyethylene Waste Recycling?
Polyethylene is a commonly used plastic material that comes in two main types: low-density polyethylene (LDPE) and high-density polyethylene (HDPE). Polyethylene recycling involves the collection of used polyethylene products, their separation, processing, and transformation into new products. This process helps reduce the amount of plastic waste in nature, contributing to the conservation of natural resources and reducing energy consumption.
The environmentally friendly practice of polyethylene recycling is carried out to efficiently use resources and minimize waste. Additionally, recycled plastic materials can be reused as raw materials in industrial processes.
How is the Recycling of Polyethylene Waste Done?
The recycling of polyethylene is carried out through specialized processes in recycling facilities. The following steps are commonly followed in polyethylene recycling:
- Used polyethylene waste is collected and separated according to their types.
- The separated polyethylene materials are cleaned to remove unnecessary substances. Labels, coatings, and other contaminants are removed.
- The cleaned polyethylene waste, prepared for recycling, is broken down and ground into pieces through specific processes.
- The ground polyethylene pieces are melted to form a liquid. This molten polyethylene is passed through an extrusion machine to be transformed into specific shapes and molds. New polyethylene products can be shaped at this stage.
- The polyethylene that undergoes the extrusion process is turned into granules. These granules are stored to be used as raw materials, and they can be preferred in the production of new plastic products.
Polyethylene waste recycling is a crucial process for the conservation of natural resources and human health. The reuse of polyethylene waste in manufacturing supports sustainability in industrial production.
