What GPE does

GPE Co., Ltd. (株式会社GPE) is a privately held Japanese plant engineering company founded on September 20, 2013 by Hideki Tanibata (谷端一樹) and headquartered in Minato-ku, Tokyo. The company builds custom environmental and renewable-energy process equipment, with three core product platforms: (1) woody biomass gasification power generation systems in the 500-2,000 kW range, protected by Japanese Patent No. 6551745 and built around a directly connected pyrolysis furnace and reformer that captures tar in a carbonized layer and drives valve-free rotary engines repurposed from automotive applications; (2) small-scale geothermal/hot spring power generation systems designed to operate at 110°C+ spring source temperatures with scale-resistant, simple architecture targeted at existing onsen wells; and (3) rotary-type Regenerative Thermal Oxidizer (RTO) equipment for VOC and odor treatment across printing, painting, lamination, water treatment, food, and animal-industry applications.

GPE generates revenue through a combination of professional plant engineering services (consulting, planning, design, and equipment procurement for chemical plants, biomass installations, cogeneration systems, energy-saving retrofits, and contaminated soil purification) and proprietary equipment sales, with a published starting salary of ¥220,000/month suggesting a primarily Japanese B2B cost structure. Customer acquisition runs through direct website inquiry, with separate domestic and overseas contact channels, and customer segments span Japanese chemical and industrial plants, hot spring operators, and local-government-led renewable energy projects. The company holds a multi-category Tokyo Governor Special Construction License (特―1 No. 143903) and a technical advisory relationship with Professor Jun-ichiro Hayashi of Kyushu University's Institute for Materials Chemistry and Engineering; in October 2020 it received Japan Science and Technology Agency (JST) support for a biomass gasification demonstration project, and Peter Duffy was appointed non-executive director in February 2026. Registered capital is ¥20 million; the company is founder-owned with no disclosed external funding.

Core offering

GPE is a plant engineering company that delivers comprehensive services from consulting, planning, and design through to materials and equipment procurement. The firm develops and supplies proprietary environmental and renewable energy systems, including woody biomass gasification power generation (500-2,000kW), new geothermal/hot spring power generation, and rotary-type Regenerative Thermal Oxidizer (RTO) systems for VOC treatment.

Product overview

GPE is a plant engineering company offering three core power generation and environmental processing products: (1) Woody Biomass Gasification Power Generation (500-2,000kW) using a proprietary gasification process with rotary engines; (2) New Geothermal/Hot Spring Power Generation for small-scale geothermal applications; and (3) VOC Processing Equipment using Regenerative Thermal Oxidizer (RTO) technology. All systems are designed with simplicity and cost-efficiency as core principles, leveraging the engineering team's experience in oil, gas, chemical, and industrial facilities.

Products and services

• Woody Biomass Gasification Power Generation System (木質バイオマスガス化発電) A 500-2,000kW gasification power generation system using GPE's proprietary process. The system converts woody biomass through thermal cracking (not combustion), reforms tars into clean gas, and supplies it to a rotary engine (diverted from automobile engines) for electricity generation, with hot water as a secondary output. Targeted at industrial and local government renewable energy projects.
• New Geothermal (Hot Spring) Power Generation System (新型地熱発電（温泉発電）) A small-scale power generation system utilizing artesian hot spring sources. The simple, scale-resistant system operates at 110°C+ spring source temperatures and can be applied to existing hot spring wells, offering low-cost and low-efficiency power generation for hot spring (onsen) facility operators.
• VOC Treatment Equipment - Rotary Type Regenerative Thermal Oxidizer (VOC処理設備（蓄熱式脱臭炉）) A high-temperature processing system for exhaust gases containing VOCs and various rarefied/odorous gases. The rotary-type regenerative thermal oxidizer (RTO) achieves high thermal efficiency, reduces CO2 emissions, and saves energy while treating VOCs from printing, painting, lamination processes and odors from water treatment, food, and animal industries. Targeted at chemical and industrial plant operators needing emission control.
• Plant Engineering Services (プラントエンジニアリング事業) Comprehensive plant engineering services covering VOC countermeasures, various gasification plants, chemical plants, energy-saving proposals, energy-saving engineering, cogeneration systems, biomass power generation planning and engineering, RTO equipment, contaminated soil purification equipment engineering, equipment design and procurement, unit/skid design, and catalyst/energy-saving consulting. Targeted at chemical, petrochemical, and industrial plant operators.
