A PP or PE recycling line should be defined from the incoming waste and required output. Film, woven bags, rigid items and mixed post-consumer material can have different contamination, sorting, washing, drying, feeding and filtration needs.
Send representative feedstock samples or clear photos from several batches. State which sorting and size-reduction steps already exist and whether the required output is clean flakes, pellets or both.
Typical equipment scope
- Feed opening, sorting and metal-removal equipment when required
- Size-reduction equipment selected for the feedstock
- Pre-washing, friction washing and separation stages
- Rinsing, dewatering and drying equipment
- Buffering, compaction or controlled feeding before extrusion
- Extruder, filtration and pelletizing equipment when pellets are required
- Water circulation, sludge handling and collection interfaces
The line scope should identify wastewater treatment boundaries, buyer-supplied services and whether pelletizing is included.
Information needed for a proposal
- PP, PE or mixed feedstock and its source
- Film, bag, rigid or other incoming form
- Typical contamination types and estimated ranges from samples
- Existing sorting, crushing or washing steps
- Required clean-flake or pellet output
- Pellet shape and filtration expectations when applicable
- Daily feed variation and target production rate
- Water quality, circulation and discharge requirements
- Available power, steam or heating, compressed air and floor space
- Local environmental and wastewater requirements supplied by the buyer
Frequently asked questions
Can film and rigid material run on the same line?
Their bulk density, contamination, washing and feeding behavior can differ. Provide the production mix so shared and feedstock-specific stages can be identified.
Is pelletizing always required?
No. Some projects stop at clean flakes, while others need filtered pellets for a defined next process. State the required sale or reuse form before equipment selection.
How is wastewater equipment selected?
The design depends on contamination, washing chemistry, water reuse, discharge conditions and local requirements. The buyer should provide applicable rules and site conditions.
