How Does Plastic Recycling Work?

On the other hand, gasification converts plastic to gas. Producers use the gas gotten from this process to create energy.

Plastic is everywhere around us. From drink bottles to supermarket bags to your ID card, we see and use plastic on a daily basis. Many of these polymers are made with petrochemicals. Plastic pollution can have both beneficial and harmful repercussions on our environment.

Plastic has the potential to harm the environment and generate waste. Humans and the environment may be affected as a result of these effects. Furthermore, if plastic is not well maintained, it may be a waste of resources to create new ones. It is, therefore, appropriate to reuse and reprocess plastic in order to reduce waste.

What method is used to recycle plastic?

Plastic is available in many different shapes and sizes. As a result, it's impossible to recycle all plastics in the same way. Plastic, on the other hand, has two options for recycling.

Recycling as it has always been done

This is the most prevalent way of recycling. Traditional recycling is also known as mechanical recycling. This process can be used to recycle thermoplastic materials.

Melting polymers and turning them into new plastic goods is the classic recycling technique. After melting the plastic, recyclers employ injection molding to make new objects out of it.

Plastic Recycling: A Step-by-Step Guide

It is not as difficult to recycle plastic as it is to make new plastic items. On the other hand, recycling plastic is a difficult operation. It demands rigorous methods and a keen eye for detail. It's possible that the treatments will take months to finish.

Plastic, regardless of its type or intended application, usually goes through a few basic stages throughout recycling. The following are the six most important procedures in the recycling of plastic products.

Step 1: Waste Plastic Collection

Collecting discarded plastic objects is the initial stage in plastic recycling. This procedure may appear straightforward, but it is not.

Employees or volunteers collect garbage plastic from homes, offices, and public areas at this step. People can dispose of their plastics at collection points in certain localities.

To make collection easier, some recyclers place recycling bins in public places, residential neighborhoods, and industrial zones. These bins can be used to dispose of plastic garbage. The recycle bins are then collected and delivered to recyclers, where the process can continue.

Manually collecting plastics or depositing plastic debris in recycling bins can often provide dividends. At this point, recyclers gather all forms of plastic and transport it to a collection yard. 

Step 2: Plastic Sorting into Different Types

Plastic is collected by recyclers and transported to facilities where it is divided into several forms. Plastics exist in a wide range of sizes, colors, thicknesses, and applications, as you probably already know. In this procedure, recycling machines sort plastics into several categories based on their properties.

Color and resin content in plastic are widely used by recyclers to distinguish plastics. Sorting is required because it provides information to recyclers about the materials involved and how they are recycled.

Step 3: Impurities are removed by washing

After sorting plastics, recycling businesses wash them to eliminate impurities. Impurities in plastic include paper labels, grime, and particles. After sorting plastics, recycling businesses wash them to eliminate impurities. Impurities in plastic include paper labels, grime, and particles.

Contaminants can harm a new product if they are not removed, so it is necessary to wash it. In addition, the pollutants contained in plastic products aren't necessarily recyclable and aren't usually made of plastic.

Step 4: Resizing and shredding

This occurs immediately following the washing of the plastics. Because plastic is too developed to be recycled in its current state, it cannot be recycled. In order to be recycled, the plastic material's size must be reduced. In the fourth procedure, shredders will be used to shred the plastic into fragments.

Plastic is easier to process when it is split into little pieces than when it is in its natural state. Shredding allows the plastic to be recycled into materials other than plastic products. Resizing also makes it easier to spot items like metal that recyclers missed during the washing process.

Step 5: Plastics Separation and Identification

Following the resizing, the next step is to identify and separate the various plastic materials. During this process, plastic particles are put through a series of tests.

The goal of plastic testing is to figure out what kind of plastic it is and how good it is. The plastic ingredients are then sorted for further processing based on their characteristics.

Several aspects are put to the test throughout this procedure. Density is one of these properties. To test the density of plastic, recyclers place these plastic particles into a container of water. Particles that sink have a lower density than those that float.

The air classification of plastic materials is another attribute that this method checks for. The thickness of the plastic is determined by its air classification. Recyclers also put plastic particles into a wind tunnel to determine air classification. Plastic that is thicker and larger will remain at the bottom of the wind tunnel. The ones that are thinner will float.

This stage also determines other characteristics of plastic, such as color and melting point. Samples of plastic materials are tested by recyclers to establish the melting point and color of each substance. They remove the plastic particles after the identification procedure and send them to be processed further.

Recycling Plastic Has Its Benefits

You may be asking why recycling is such a good idea. After all, the procedure appears to be time-consuming, and you must explain it based on its advantages. It does, however, have a number of advantages. And it is for these reasons that you should support recycling.

  • The amount of waste that ends up in the oceans is reduced by recycling plastic.
  • New jobs are created as a result of plastic recycling.
  • For the government and commercial entities, plastic recycling generates additional cash.
  • Recycling plastic decreases the amount of carbon dioxide and other hazardous gases released into the atmosphere.
  • Plastic recycling reduces the amount of area taken up by landfills. It allows the landfills to be used for other purposes.
  • Recycling conserves petroleum, which can be used to create new plastics.
  • Plastic recycling reduces the amount of energy used by manufacturers to create new products. 
  • Global warming is avoided by recycling plastic.
  • Plastic recycling helps to reduce pollution of all kinds.
  • Volunteers who collect plastic debris earn money by recycling it.
  • Plastic recycling aids in the reduction of activities such as deforestation that occur during the manufacture of new plastic.
  • Encourages people to live a more sustainable lifestyle
