How Does Plastic Recycling Work?
Plastic recycling is a process of recovering plastics and turning them into new products. It is an essential step towards sustainable waste management and environmental preservation. Recycling plastic saves energy, reduces greenhouse gas emissions, and conserves natural resources. But how does plastic recycling work, and what happens to the plastic after it is collected?
Collection and sorting.
The first step in plastic recycling is collecting the plastic waste. Plastic waste is collected from households, businesses, and public places and transported to recycling facilities. At the recycling facilities, the plastic is sorted by type, color, and quality. This is crucial because different types of plastic have distinct properties that affect the recycling process and the quality of the final product. Plastic is sorted by machines and humans who manually separate the plastic waste based on the resin identification code on the plastic.
Cleaning and shredding.
After sorting, the plastic is cleaned to remove any contaminants such as labels, glue, dirt, and food residues. Cleaning is done through a process of washing, rinsing, and drying. Once the plastic is clean, it is shredded into small pieces called flakes. Shredding makes the plastic more manageable and creates a large surface area that facilitates melting.
Melting and extrusion.
The next step is melting and extruding the plastic flakes into pellets. The plastic pellets are melted in a furnace and then injected into a mold to form a new product. Different methods can be used to melt the plastic, including heat, pressure, and friction. In some instances, additives such as colorants, plasticizers, or UV inhibitors can be added to the melted plastic pellets to modify the properties of the final product.
The final product.
The final product of plastic recycling can vary depending on the type of plastic being recycled and the end product's intended use. For instance, recycled plastics can be used to make new bottles, bags, packaging materials, toys, furniture, and construction materials. When recycled plastic is used to make new products, it reduces the need for virgin plastic, conserves resources, and reduces waste.
