Plastic resins form the foundation of all synthetic materials, and they’re typically produced via the thermal cracking of hydrocarbons. Over recent decades, these man-made substances have transformed industries, commercial sectors, and households alike. However, with growing global emphasis on environmental protection policies, it’s critical that the plastics we produce and consume are biodegradable and adhere to regulations regarding plastic waste management. Utilizing recycled resins represents a significant advancement in this direction. Moreover, this shift benefits not only plastic manufacturers but also their product makers, distributors, and final consumers. This article explores the fundamentals of recycled resins and their rising adoption in injection molding.
### Why Opt for Recycled Resins?
What exactly are recycled resins? They're derived from used plastics, often referred to as Post-Consumer Recycled Resin (PCR). Despite some challenges in the recycling process, this method creates eco-friendly plastics and provides numerous advantages. Here are some key benefits of using recycled resins:
- Fossil fuels aren’t consumed to manufacture new or "virgin" plastic.
- It significantly reduces non-biodegradable waste generated by humans.
- It lowers greenhouse gas emissions.
- For resin producers, this not only cuts costs but also enhances brand image as an environmentally-conscious entity.
- It decreases expenses while boosting profitability.
- In terms of quality, recycled resins match those of virgin plastic.
### Environmental Gains from Recycled Resins
A study by Franklin Associates (U.S.) found that utilizing recycled plastics reduces greenhouse gas emissions by at least 25% compared to virgin plastics. It's vital for end-users to purchase items made from regrind resins. Virgin plastics take over 500 years to degrade, clogging landfills worldwide. A practical solution is for more suppliers to acquire regrind resins and collaborate with individuals or businesses looking to sell them. The most common recyclable resin types include:
- Polyvinyl chloride
- Polyethylene terephthalate
- Polypropylene
- Polystyrene
- High-density polyethylene
- Low-density polyethylene
### Advantages of Recycled Resins in Injection Molding
Injection molding, a popular technique in the polymer sector, involves injecting molten materials into molds. Once cooled, the material conforms to the mold’s shape, enabling mass production of identical plastic parts. Over the last several years, many Original Equipment Manufacturers (OEMs) and plastic manufacturers have expressed interest in employing recycled resins for injection molding. Several factors contribute to their growing popularity among molders:
- First and foremost, recycled resins perform just as well as virgin ones, ensuring consistent product quality.
- Fewer raw materials are needed when using recycled resins for injection molding or similar industrial processes.
- Manufacturers can establish a closed-loop system by repurposing recycled parts into new components in-house.
- It minimizes costs and shields against fluctuations in petrochemical pricing within the industry.
- Companies can partner with local customers or entities to source used plastics that might otherwise accumulate in landfills.
### Conclusion
Overall, the advantages of using recycled resins are evident, prompting more plastic product manufacturers and end-users to adopt them. As economies of scale are realized, costs are expected to decline further. Nonetheless, it’s imperative to source regrind resins from reputable suppliers. MidContinent Plastics stands out as a premier provider of recycled resins for injection molding, boasting over three decades of market presence. The company offers an extensive range of recycled resins, including ABS, Cellulosics, Nylon 66, MPR, Polyetherimide, Polyphenylene sulfide, and more.
