The procedure of Recycling of Plastics Material :
Step 1: Collection of Waste Plastic
Step 2: Sorting of Plastics into Categories
Step 3: Washing to Remove Impurities
Step 4: Shredding and Resizing
Step 5: Identification and Separation of Plastics
Step 6: Compounding
The recycling of plastic is not as hard as manufacturing new plastic products. Nonetheless, plastic recycling is not a walk in the park. It involves rigorous procedures and attention to detail. The processes may take months.
Irrespective of the type of plastic and its usage, it usually undergoes some general steps during recycling. Here are six essential steps to recycle plastic materials
Step 1: Collection of Waste Plastic
The first step to plastic recycling is gathering waste plastic products. While this process may seem like an easy task, it is not entirely so.
At this stage, employees or volunteers go around collecting waste plastic from homes, offices, and public places. Certain areas have collection sites where people can dispose of their plastics.
Step 2: Sorting of Plastics into Categories
After collection, recyclers send the plastic they have gathered to facilities where they separate the plastics according to types. As you must already know, plastics differ in size, color, thickness, and use. In this process, recycling machines sort plastics based on the properties of the material.
Often, color and the resin content in the plastic are the basis by which recyclers sort plastics. Sorting is essential because it allows recyclers to know which material is involved and how it gets recycled.
Step 3: Washing to Remove Impurities
After sorting plastics, recyclers wash the materials to remove impurities. These impurities in plastic include paper labels, dirt, and particles. Washing plastic also removes glue and additional chemicals that plastic materials may contain.
Washing is essential because failure to remove impurities may damage the new product. Moreover, the contaminants contained in plastic products are not plastic materials and may not be recyclable.
Step 4: Shredding and Resizing
This process comes immediately after washing plastics. It is impossible to recycle plastic in its already developed state. There is a need to resize the plastic material to a form that can be recycled. In this fourth process, materials will be put into shredders to reduce the plastic into fragments.
A plastic material cut into tiny pieces is more comfortable to process than when it is in its original form. Shredding also makes it possible to reprocess plastic to other materials aside from plastic products. Resizing also makes it easier to identify elements like metal that recyclers failed to discover during washing.
Step 5: Identification and Separation of Plastics
After resizing has been completed, the next process is to identify and separate plastic materials. In this process, plastic particles undergo testing procedures.
The reason for testing plastics is to identify the class and quality of the plastic. The plastic materials are then separated based on their features for further processing.
There are several features tested in this process. One of these qualities is density. Recyclers place these plastic particles into a container of water to determine the density of plastic. The particles that sink are less dense, while those that float are denser.
Step 6: Compounding
Compounding is the final process in plastic recycling. This step is where recyclers transform plastic particles into materials that manufacturers can reproduce. Compounding involves smashing and melting plastic particles to create pellets. This process is also called extrusion.
Sometimes, recyclers move plastic to different areas where they can be recycled. The recyclers may move the materials to other plants because of the features in step five. A recycling company may not have the capacity to process all the plastic types it identifies.
