## About

POLASTECH Inc. is a Japan-based company specializing in advanced cooling energy solutions, utilizing innovative adsorption heat pump technology to improve energy efficiency and sustainability across various sectors.Founded in 2025, POLASTECH Inc. operates from its headquarters in Tokyo, Japan, focusing on the development of heat recovery technologies. The founder's detailed history is currently not available, nor is information about any prior ventures. POLASTECH Inc. specializes in advanced cooling energy solutions through its innovative adsorption heat pump technology, utilizing low-temperature waste heat. Their core product, AQSOA®, a zeolite-based adsorbent, efficiently captures moisture and transforms waste heat into usable cooling energy. This technology is particularly advantageous for data centers and industrial sectors, greatly reducing electricity consumption and CO2 emissions. The company serves a diverse clientele in Japan and beyond, focusing on applications like server cooling and industrial process cooling. POLASTECH Inc. generates revenue primarily through the sale of its AQSOA® adsorbent and the development of associated adsorption heat pump systems. Operating on a B2B transactional model, the company partners with industrial clients and data center operators to deliver energy-saving solutions, leading to consistent revenue through direct sales and long-term contracts. The pricing structure reflects the advanced engineering and sustainability benefits of their products, although specific costs are proprietary. In September 2026, POLASTECH INC. raised JPY 140 million in Seed funding from Spiral Capital, Tokai Innovation Institute and Shibata Welding Works Ltd.
The company plans to use the September 2026 funds to expand AQSOA® production, advance AHP system development, and support business growth and overseas expansion.
