What DAISAKU CO LTD does
DAISAKU CO LTD (大作商事株式会社) is a privately held Japanese plastic recycling manufacturer founded in December 2002 by Shinsaku Kobayashi in Adachi-ku, Tokyo, and currently led by second-generation representative director Ryuichi Nunozaki. The company operates a vertically integrated recycling business spanning four facilities: a Tokyo headquarters (sales/administration), a Kanto office in Ibaraki (logistics center with 5 extruders processing ~2,000 tons of resin per month), an Ibaraki crushing factory (5 shredders, 15 grinders, 10 forklifts), and an Ibaraki compounding factory (2T tumblers, polystyrene specialization). Its core products are regenerated plastic pellets (LDPE, HDPE, PP, HIPS, PS, ABS) produced through single-material recycling with manual contaminant sorting, alongside plastic recycling equipment (ZSS shredders, GSH grinders, dehydrators, density separation tanks), flexible intermediate bulk containers, commissioned processing services, and container packaging recycling under Japan's Container Packaging Recycling Law.
The company serves four primary customer segments: domestic manufacturing factories (primary, supplying waste plastic and procuring recycled raw materials), waste disposal companies, container packaging recycling participants, and international plastic recycling firms (exporting to over 30 countries across 5 continents, anchored by China). Revenue is generated through multiple streams: recycled pellet sales, waste plastic purchasing (securing raw material input), equipment sales, commissioned processing services, and flexi bag sales. Pricing is largely inquiry-based; only the standard flexible container bag is publicly priced at ¥550 per piece. Go-to-market relies on direct B2B sales, industry exhibition participation (notably Environment Expo 2025), and a logistics team handling international export with full documentation.
DAISAKU holds ISO 9001 certification (2010), AQSIQ certification for China trade (2012), and certified product user status with the Japan Container Packaging Recycling Association. These regulatory credentials, combined with the company's guarantee of full domestic (non-overseas) recycling and in-house physical testing, form the spine of its value proposition. The business is small (42 employees per company profile, or 12 per firmographic data; ¥10M registered capital) with no disclosed institutional investors, parent companies, or M&A activity. Its growth trajectory is unclear from public data — the most recent major capital deployment was the 2018 Kanto office expansion, but the firm continues to actively trade and exhibit commercially in 2025.

Revenue model
- Plastic Raw Material Sales: Sale of regenerated plastic pellets including LDPE, HDPE, PP, PS, ABS varieties. High-quality pellets produced through single-material recycling with manual sorting to remove contaminants. Main revenue driver.
- Waste Plastic Purchasing: Purchase of waste plastics from clients, processing them into valuable resources rather than disposal. Enables clients to monetize waste while company secures raw materials for pellet production.
- Commissioned Processing: Contract processing services where customers send plastic waste (sprues, defective molding, inventory disposal items) for regeneration into high-quality pellets. Equipment investment not required for clients.
- Plastic Recycling Equipment Sales: Sale of Chinese-made plastic recycling equipment including shredders, grinders, dehydrators, and density separation tanks. Low-cost, high-performance equipment for domestic plastic recycling companies.
- Packaging Materials Sales: Sale of flexi bags (flexible container bags) for waste storage and transport. Standard types and custom specifications available.
- Container Packaging Recycling: Container packaging recycling under Japanese law. Processing household-collected container packaging plastics into compounded and colored materials for manufacturing.

DAISAKU CO LTD competitors and assessment
Company assessmentEmerging players
- Plastic Energy: UK/Spain-based advanced (chemical) recycling company converting end-of-life plastics into recycled feedstocks. Comparable focus on circular plastics but uses thermal depolymerization rather than mechanical regeneration.
- MBA Polymers: US-headquartered plastics recovery firm producing post-consumer recycled PP, ABS, and HIPS grades. Comparable product portfolio in technically demanding recycled resin markets, though focused on automotive and appliance streams.
- GreenChip Holdings: Israel-based plastic recycling company producing food-grade rPET and rHDPE. Comparable output grades (especially rHDPE) but uses advanced decontamination technology versus DAISAKU's mechanical approach.
Broad incumbents
- Veolia Environnement: Global waste management and recycling conglomerate. Comparable in plastics recovery and MRF operations but at vastly larger scale and with broader environmental services portfolio.
- Stericycle, Inc. US-based regulated waste and recycling services company. Comparable in waste collection and processing infrastructure for industrial clients, though focused more on hazardous and medical waste streams.
- Toyo Seikan Group Holdings: Major Japanese packaging manufacturer with significant PET bottle-to-bottle recycling operations. Comparable in container packaging recycling and pellet production but operates at much larger scale and is vertically integrated into packaging end products.
- JSP Corporation: Japanese plastics processor specializing in foam and bead products with internal recycling operations. Comparable in industrial plastics processing and Japanese manufacturing focus, but oriented toward finished products rather than pure recycling.
- Suez SA: International water and waste management group with significant plastics recycling operations in Europe and Asia. Competes in MRF and recycled resin supply but serves a much wider customer base and geographies.
Direct peers
- Recycle One Co., Ltd. Japan-based plastic recycling company operating materials recovery and pellet production. Directly comparable as a domestic mechanical recycler serving manufacturers with regenerated resin and waste collection services.
- Minato Sangyo Co., Ltd. Japanese plastics recycler with shredding, washing, and pelletizing operations. Comparable vertical integration profile and target customer base of Japanese manufacturers with plastic scrap.
