Hamee Co., Ltd. (headquartered in Odawara City, Kanagawa Prefecture; President and CEO: Ikutaka Mizushima; TSE Standard: 3134) has launched a 'Material Provenance & Environmental Impact Certificate' for upcycled products through its plastic recycling service, Parallel Plastics (Parallel Plastics). The certificate, summarizing the material's origin and estimated environmental impact, will be standardly attached to deliveries from co-creation projects.

Unlike generic LCA databases that rely on industry averages, this certificate is distinctive for being based on primary data from actual collection, shredding, and molding processes—detailing exactly how waste plastic was transformed into specific products.

Background: Companies Are Required to Prove 'Use of Recycled Materials'

Under the revised Resource Effective Utilization Promotion Law, effective April 2026, manufacturers are increasingly required to explain their plans and actual use of recycled materials. The need for verifiable evidence—showing 'which materials, how much, and with what history were used'—is also growing in ESG reports and for compliance with Europe’s PPWR (Packaging and Packaging Waste Regulation).

Meanwhile, standard LCA assessments rely on industry averages and cannot trace the specific journey of 'this material becoming this product.' Parallel Plastics fills this gap by leveraging primary data collected throughout its own transformation processes.

Certificate Contents

Provenance: Clearly discloses the supply source, collection (as valuable material), physical transformation (shredding, molding), and productization, using lot-level primary records.

Environmental Impact (LCA Estimate): Includes estimated CO₂ reduction compared to manufacturing with virgin resin, recycled material content rate, and calculation scope.

Use Cases: Can be used as supporting documentation for reporting recycled material usage plans and results, ESG reports, and PPWR compliance.

※ This certificate is a self-declaration by Parallel Plastics and not third-party certified. Environmental impact figures are estimates and will be finalized and updated as actual measurements and sources become available. To avoid exaggeration, limitations are clearly stated upon issuance.

Issuance Examples (Co-Creation Project Cases)

・ Collaboration with a baby care products manufacturer: Manufacturing offcuts (PP) from their own production line were used as 100% recycled material for commemorative items. Any material not suitable for the final product was reused by Parallel Plastics into other products.

・ Collaboration between a department store and a haircare cosmetics brand: Empty cosmetic containers collected at retail counters and discarded residential fixtures were transformed into 100% recycled plastic hair combs.

About 'Parallel Plastics'

'Parallel Plastics' is an upcycling service that gives new life to plastic waste—such as warehouse overstock, manufacturing offcuts, and used resins—that would otherwise have no destination. It supports product development that balances sustainability, design, and mass producibility while preserving material uniqueness. Rather than simply stating 'we recycled,' the service delivers tangible proof: 'this waste plastic became this product in this way.' This certificate is the embodiment of that principle.

Companies facing challenges in planning or reporting recycled material usage, and brands wishing to communicate circularity as a 'story,' are welcome to consult.
