Understanding Plastics Recycling: Post-Industry vs. Post-Consumer

Plastic recycling is an essential part of waste reduction and resource conservation. However, not all plastic waste is created equal. The two main types of plastic recycling are post-industrial and post-consumer. Although both aim to recycle plastic and reduce landfill waste, they differ in their terms and processes. In this article, we explain the differences between these two recycling methods and their respective benefits.

What is post-industrialplastic recycling?

Post-industrial plastic recycling refers to plastic waste generated during the manufacturing process of plastic products. This waste is usually clean, free of contaminants, and produced in large quantities. For plastic manufacturers, recycling their own waste is not only an environmentally friendly choice, but also a cost-effective strategy. Instead of sending the waste to landfill, it can be directly re-incorporated into the production process.

A major advantage of post-industrial recycling is the control and homogeneity of the waste material, which facilitates processing. With recycling machines from Rumtoo 100% of plastic waste from production can be returned to the production lines, reducing the need for new raw materials and reducing overall production costs.

What is post-consumer plastic recycling?

Post-consumer plastic recycling refers to plastics that have already been used by consumers. This waste comes from households, businesses or other commercial establishments. Post-consumer plastics, also known as PCR (post-consumer recycled) materials, are recycled into new products to close the plastics loop. However, recycling post-consumer plastics is far more complex due to challenges such as contamination, varying plastic types and the need for extensive sorting.

Before recycling, post-consumer plastics must be thoroughly cleaned and sorted into categories. A washing line is often required to remove contaminants and moisture control to ensure the recycled pellets are of acceptable quality. The diverse nature of post-consumer plastics - from bottles to bags - makes consistency in the final product difficult.

Key differences between post-industrial and post-consumer recycling

Origin of plastic waste:

• Post-Industry: Created during production and is usually free of impurities.

• Post-Consumer: Collected after use by the consumer.

Contamination and sorting:

• Post-Industry: Plastic is mostly clean and the types of waste are predictable.

• Post-Consumer: Waste must be sorted and cleaned frequently to remove dirt and moisture.

Control over plastic composition:

• Post-Industry: Manufacturers know the exact type of recycled plastic, which ensures consistent material quality.

• Post-Consumer: The composition of plastics varies greatly because they come from different consumer products.

Complexity of the recycling process:

• Post-Industry: Less complex due to control over waste materials.

• Post-Consumer: More complex because additional steps such as cleaning, sorting and moisture control are required.

Benefits and Challenges of Post-Consumer Recycling

Despite its complexity, post-consumer recycling offers significant environmental benefits. It helps reduce landfill waste, lowers CO₂ emissions and conserves resources. However, the process is often more expensive due to the costs of sorting, cleaning and processing. Companies like Rumtoo have overcome these challenges by developing advanced recycling solutions that make it easier for companies to recycle post-consumer plastics and produce sustainable products.

Conclusion

Whether you focus on post-industrial or post-consumer plastics recycling, understanding the differences is critical to choosing the right equipment and processes. Post-industrial recycling is typically more straightforward, with fewer challenges and greater material consistency. Post-consumer recycling, on the other hand, is more complex, but offers significant environmental benefits. With the expertise of Rumtoo In both areas, companies can efficiently manage both types of plastic waste and thus position themselves as pioneers in the sustainable industry.
