Core offering

Street Design designs, manufactures, and sells small-to-medium-scale biomass gasification power generation systems that convert diverse organic wastes into electricity, heat, and green hydrogen via a separated carbonization-and-gasification process. It also sells waste plastic oilification equipment that thermally decomposes plastics into liquid fuel and hydrogen, and the MLIT-certified Connect Sealer Series of asbestos encapsulation chemicals, complemented by construction, asbestos remediation, and custom system design services.

Product overview

Street Design (株式会社ストリートデザイン) offers three main product lines: (1) the Organic Waste Renewable Energy Conversion System (有機系廃棄物再生エネルギー変換システム), a biomass gasification system that converts diverse organic waste into electricity, heat, and green hydrogen; (2) Waste Plastic Oilification Equipment (廃プラスチック油化装置) that thermally decomposes plastic into liquid fuel and hydrogen; and (3) the Connect Sealer Series (コネクトシーラーシリーズ) of asbestos encapsulation agents with MLIT government certification. The company also provides custom system design services for organic waste energy conversion, waste plastic energy conversion, and integrated combined systems. All products support circular economy goals by converting waste into renewable energy while reducing CO2 emissions.

Products and services

• Biomass Gasification Power Generation System (有機系廃棄物再生エネルギー変換システム) Small and medium-scale equipment that converts diverse organic waste into electricity, heat, and hydrogen-rich syngas using a proprietary separated carbonization-and-gasification process. Designed for municipalities and industrial enterprises seeking waste-to-energy solutions, with green hydrogen recovery and near-zero CO2 emissions after startup. Includes feasibility study, business process assembly, and commercialization support.
• Waste Plastic Oilification Equipment (廃プラスチック油化装置) Thermal decomposition equipment that converts waste plastics from solid/liquid/gas states into liquid fuel and industrial raw materials, with the capability to generate hydrogen gas from decomposition gases. Designed for enterprises and municipalities with plastic waste recycling or circular-economy objectives.
• Connect Sealer Series (コネクトシーラーシリーズ) — Asbestos Encapsulation Chemicals (S and R variants) Government-certified asbestos encapsulation chemicals for asbestos treatment and construction applications. Uses wetting and penetration properties to bond asbestos fibers while maintaining flexibility, fire resistance, thermal insulation, and acoustic properties. Holds MLIT certification No. MAEN-0015 under Building Standards Act Article 37 Item 2. Available in small quantities from 5 kg, applied via airless spraying.
• Custom System Design Services (システム設計例) Custom engineering design services for organic waste energy conversion systems, waste plastic energy conversion systems, and integrated organic-waste-plus-plastic combined systems. Tailored to specific waste streams and customer energy requirements, available as part of feasibility study and commercialization support.
• Construction and Asbestos Treatment Services Construction services including concrete structure repair and reinforcement, waterproofing, civil engineering, building works, and asbestos treatment (encapsulation through to low-temperature melting harmless processing and recycling). Provided to public-sector and private customers in Japan.
