PP regrind
PP Regrind

It’s common to see them as plastic chairs, toy parts, baskets, trash cans, pipes, bottles, bottle caps, and others because they provide stronger protection for goods.

HDPE regrind
HDPE Regrind

HDPE regrind is widely used in containers, plastic bottles, pipes, playground equipment, and more due to its high strength, impact resistance, and chemical durability.

PVC regrind
PVC Regrind

PVC regrind is widely used in pipes, flooring, cable insulation, and window frames due to its durability, chemical resistance, and adaptability for various applications.

ABS regrind
ABS Regrind

ABS regrind is commonly used in automotive parts, electronics housings, toys, and appliances, valued for its toughness, impact resistance, and excellent surface finish.

Rigid plastic
Rigid Plastic

Producers are exploring solutions for PE pipes, PP containers, ABS automobile components, and more, and the origins of these wastes are diverse across industries.

PET regrind
PET Regrind

PET regrind is extensively used in bottles, food containers, and packaging materials due to its strength, clarity, and excellent barrier properties, making it ideal for preserving freshness.
