In today's world, plastic has become an essential part of almost every industry and application. One of the main reasons for its widespread use is its durability, but another major factor is its recyclability. With growing environmental concerns, recycling plastic has become a key focus for many businesses and governments. Scrap plastic can be transformed into new products through various methods, 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 expand from USD 34.80 billion in 2016 to USD 50.36 billion by 2022, reflecting a compound annual growth rate (CAGR) of 6.4%.
Recycling scrap plastic involves multiple steps and processes that are crucial for transforming waste into useful materials. If you're curious about how scrap plastic is recycled, keep reading this post to learn more.
What Are the Different Processes Involved in Plastic Recycling?
When it comes to plastic recycling, there are several key methods used to process and reuse old plastic materials. Two of the most common and effective techniques include:
- Monomer Recycling Process: This method involves breaking down polymers back into their original monomers, allowing them to be re-polymerized into new plastics. It’s especially useful for certain types of plastics like PET, and it helps reduce waste while maintaining material quality.
- Heat Compression Process: Widely used in countries such as Japan and the United States, this technique allows for the recycling of different types of plastics without the need for sorting. The process involves melting and compressing the plastic to form new shapes or products.
What Are the Various Stages in Recycling Scrap Plastic?
Once the recycling process begins, there are several important stages that must be followed to ensure the final product is of high quality. Here’s a breakdown of the typical steps involved:
-
- Categorization: The first step is to sort and classify the plastic based on its type, such as PET, HDPE, or LDPE. Proper categorization ensures that each type of plastic is processed correctly.
-
- Washing & Cleaning: After sorting, the plastic is thoroughly cleaned to remove any contaminants, labels, or adhesives. This step is vital to ensure the purity of the recycled material.
-
- Shredding: Once clean, the plastic is shredded into small pieces using specialized machines. This makes it easier to process further and improves the efficiency of the next steps.
-
- Quality Check & Testing: Before moving forward, the shredded plastic is tested to ensure it meets the required standards in terms of purity and consistency.
-
- Extruding: In the final stage, the plastic is melted and extruded into pellets. These pellets can then be used to manufacture new plastic products, completing the recycling cycle.
As plastic recycling becomes increasingly important in the fight against waste and pollution, the industry is set for continued growth. If you’re looking to purchase recycled scrap plastic, there are numerous recyclers across the USA who specialize in this field. However, it's always wise to work with experienced companies that have a deep understanding of the process. One such reliable recycler in the US is Mid Continent Plastics, known for its quality and expertise in plastic recycling.
