Special Plastic Recycling Materials

Pipes, Lumps
& Other Plastics

Plastic pipes, profiles, lumps and industrial production scrap can vary significantly in polymer type, dimensions, wall thickness and contamination. These materials often require project-specific size reduction and downstream recycling configurations.

Material Profile

What Special Plastic
Waste Looks Like

These materials are usually defined more by their shape, dimensions and production origin than by one standard recycling category.

01 / EXTRUDED MATERIAL

Plastic Pipes & Profiles

Long and thick-wall materials may require dedicated feeding, cutting or primary shredding before further size reduction.

02 / PURGE & START-UP

Plastic Lumps & Purge

Dense plastic lumps can place high loads on size-reduction equipment and usually require high-torque shredding.

Industrial Production Scrap

Industrial scrap can be relatively clean and consistent, potentially allowing a simpler recycling route than post-consumer material.

04 / SPECIAL COMPONENTS

Oversized / Special Plastic Parts

Large or irregular plastic parts require evaluation of size, thickness, attached components and material composition before processing.

“Other Plastics” is not a catch-all recycling promise. Material type, dimensions and condition need to be evaluated before a process is selected.

Recycling Challenges

Why Special Plastic Waste
Needs Individual Evaluation

Large dimensions, high material density, irregular shapes and unknown material composition can all change the correct recycling route.

Different Forms, Different Loads Long pipe sections and dense purge lumps create distinct feeding and size-reduction requirements.
01

Long or Oversized Dimensions

Long pipes, profiles and oversized parts may not fit standard feeding or crushing systems without pre-cutting or specialized size reduction.

02

Thick & Dense Material

Lumps, purge and thick-wall plastics can require high-torque shredding before smaller particle sizes can be achieved.

03

Unknown or Mixed Polymer Type

Industrial scrap should be identified by material type before washing, mixing or pelletizing routes are finalized.

04

Different Contamination Levels

Clean production scrap may require little or no intensive washing, while post-use pipes or parts may need additional cleaning and separation.

Engineering NoteA clean production purge and a contaminated post-use plastic pipe may both require shredding, but the downstream recycling process can be completely different.

Confirm Before ProcessingMaterial type, attached components and previous use should be confirmed before pelletizing or blending with other recycled plastics.

Attached ComponentsMetal inserts, screws, rubber, fibers or coatings may require removal or separate evaluation. Unknown, reinforced or cross-linked materials need material evaluation.

Target Output

The Right Output Depends
on the Material Condition

Some materials only need size reduction, while others may continue through washing, drying or pelletizing.

01 / SIZE REDUCTION

Size-Reduced Material

For material that only needs to be reduced for further processing or internal reuse.

Possible RoutePipes / lumps / large parts → shredding or crushing → size-reduced material

02 / WASHED OUTPUT

Clean Recycled Flakes

For contaminated feedstock that needs cleaning and drying after size reduction.

Possible RouteContaminated plastic → size reduction → washing & drying → clean flakes

03 / PELLETIZING

Recycled Plastic Pellets

For identified and prepared material; contaminated waste may need washing before pelletizing.

Possible RouteClean / prepared plastic → size reduction → pelletizing

Confirm material type and contamination before selecting an output route.

Different polymers should not be assumed compatible for pelletizing or blending.
