Industrial Plastic Waste: Sorting and Recycling Strategies
Manufacturing and packaging processes generate significant amounts of plastic waste. However, mixed plastic has little to no market value, whereas clean, sorted polymers (like PE, PP, or PET) are highly sought after. Here is how to organize your plastic streams for maximum recovery.
In short
- Sort plastic waste by polymer type to retain its value.
- Avoid contamination with oils or hazardous substances.
- Baling plastics on-site drastically reduces transport costs.
The importance of sorting at the source
Mixing different types of plastics makes recycling difficult and expensive. When plastics are mixed, their value drops drastically, and they may end up being incinerated or landfilled instead of recycled.
Implementing a clear sorting system at the point of generation—providing separate bins for different polymer types—ensures the material remains clean and highly recyclable.
Common industrial plastics: PE, PP, and PET
Polyethylene (PE) foils, Polypropylene (PP) crates, and PET bottles are among the most common industrial plastics. Each has specific recycling processes and distinct market values.
Keeping clear PE foil separate from colored foil, and ensuring PP containers are free of significant product residue, are simple steps that significantly increase the material's marketability.
Baling and logistics
Transporting unbaled plastic is mostly transporting air. Because plastic waste is low-density, logistics can quickly become the highest cost in the recycling process.
Using a baler on-site reduces logistical costs by compacting the waste into dense bales, which optimizes truck space and reduces the number of collections needed.
Frequently asked questions
- Can all types of industrial plastic be recycled?
- Most thermoplastics can be recycled, provided they are clean and sorted by type. Composite materials or heavily contaminated plastics are much harder to recycle.
- Do I need a baler for my plastic waste?
- It is highly recommended if you generate large volumes. A baler cuts down on transport frequency and makes your plastic waste much more attractive to recyclers.
