Sustainability
Circular materials and responsible manufacturing.
We integrate recovered-material processing, production management, resource use and material development into daily operations, supporting more resource-efficient industrial production.
Operating scale
Capacity designed to return recovered plastics to industrial use.
Waste-film recovery, recycled-pellet production and film manufacturing return recovered materials to industrial use.
Material circularity
From recovered film to renewed industrial material.
Recovered plastics are classified, prepared and evaluated before being processed into recycled materials for customer review and production trials.
- Recovery and collectionRecovered plastic enters the material network.
- ClassificationFeedstock is sorted by source, material, colour and condition.
- PreparationSelected material is prepared and washed for processing.
- ManufacturingMaterial is converted into pellets or film solutions.
- Industrial useSuitability is confirmed through technical review and customer trials.
ESG approach
Environmental, social and governance responsibility in practice.
Environmental responsibility
Recovered-film processing, rooftop solar generation, process-water and wastewater systems, feedstock classification and production controls support responsible resource management.
Social responsibility
Collection, transport, sorting and manufacturing create work across different skill levels. University collaboration also connects education, research and operating experience.
Governance and transparency
Named legal entities, certification scope and validity are shown separately. We continue improving the clarity of operational, technical and compliance information.
