Today, plastic materials are used across almost every industry and application. One of the main reasons for their widespread use is their durability, which makes them ideal for a variety of purposes. Additionally, their recyclability has made them an essential part of sustainable development. Scrap plastic can be reprocessed into new products, which is why the number of recycled plastic items continues to rise each year. The global plastic recycling market is expected to experience significant growth in the coming years. According to recent research, the market is projected to grow from USD 34.80 billion in 2016 to USD 50.36 billion by 2022, with a compound annual growth rate (CAGR) of 6.4%.
Recycling scrap plastic involves several steps and processes that transform waste into valuable resources. If you're curious about how scrap plastic is turned into useful products, keep reading to discover the full process.
What Are the Different Processes Involved in Plastic Recycling?
When it comes to plastic recycling, there are two primary methods commonly used:
- Monomer Recycling Process: This method involves breaking down polymers back into their original monomers. By reversing the polymerization process, this technique allows for the production of new, high-quality polymers. It's especially useful for recycling plastics that are difficult to process through other means.
- Heat Compression Process: Widely used in countries like Japan and the United States, this method allows for the recycling of multiple types of plastic at once without the need for sorting. It’s efficient and cost-effective, making it a popular choice in large-scale recycling operations.
What Are the Various Stages in Recycling Scrap Plastic?
Now that you understand the basic processes, let's take a closer look at the different stages involved in recycling scrap plastic:
-
- Categorization: The first step in the recycling process is sorting and categorizing the plastic based on its type, such as PET, HDPE, or LDPE. Each category is then processed accordingly to ensure quality and efficiency.
-
- Washing & Cleaning: After sorting, the plastics are thoroughly washed to remove dirt, labels, adhesives, and other contaminants. This step is crucial for maintaining the quality of the final product.
-
- Shredding: Once cleaned, the plastic is shredded into small pieces using shredder machines. These fragments are easier to handle and process in the next stage of recycling.
-
- Quality Check & Testing: Before moving forward, the shredded plastic is tested to ensure it meets the required standards for quality and purity. This helps maintain the integrity of the recycled material.
-
- Extruding: In the final stage, the recycled plastic is melted and extruded into pellets. These pellets can then be used to manufacture new plastic products, completing the recycling cycle.
With the growing demand for sustainable materials, the plastic recycling industry is set to expand significantly. If you're looking to purchase recycled scrap plastic, there are many reputable recyclers in the U.S. who can provide quality materials. However, it's always wise to work with experienced manufacturers who have a deep understanding of the recycling process. One such company is Mid Continent Plastics, known for its reliable and high-quality recycled plastic products.
