HDPE (High-Density Polyethylene) is one of the most relevant rigid plastic fractions in recycling. It includes detergent bottles, canisters, chemical containers, industrial packaging and drums.
Typical challenge: product residues (liquids, detergents, oils), adhesive labels and mineral contamination.
System objective: controlled size reduction, intensive mechanical and thermal washing, and density separation to isolate HDPE from foreign polymers.
Result: high-purity HDPE flakes with controlled moisture and stable properties for extrusion and blow-molding applications.
PP Rigid Plastics
Rigid PP (Polypropylene) originates from food containers, crates, buckets, technical components and rigid packaging.
Typical challenge: presence of labels, metal inserts or multi-component parts, as well as incompatible polymers.
System objective: efficient shredding and precise separation to obtain a homogeneous PP fraction while removing materials with different densities.
Result: clean and uniform PP flakes suitable for compounding and new industrial applications.
Rigid Plastics Post-Commercial & Industrial
Rigid plastic waste from industrial and commercial operations, including pallets, crates, production scrap and technical packaging.
Typical challenge: structurally robust materials often containing metal or non-plastic inserts.
System objective: efficient size reduction and removal of foreign materials to stabilize the plastic fraction.
Result: consistent recycled material ready for reintroduction into production cycles.
Rigid Plastics with Critical Contamination
Some rigid streams contain chemical residues, oils or persistent surface contamination, typical of technical or industrial containers.
System objective: integration of high-intensity washing stages with controlled chemical and thermal parameters.
Result: clean flakes free from residues that could interfere with extrusion or compounding processes.
Why the Rigid Plastics System Solution is Strategic
Rigid plastics offer high recycling potential but require robust and precisely calibrated processes. The Washtech solution is a fully integrated system, engineered to handle thick-walled materials and different polymers while maintaining process stability and output quality.
