Stella Environment Corporation

Stella Environment Corporation (株式会社ステラ環境) is a small Japanese environmental technology company headquartered in Minato-ku, Tokyo. It was founded in June 2005 as a university-launched venture in partnership with Nagasaki University. The company's founding vision centered on contributing to environmental needs through a spirit of social service, pursuing global expansion of environmental businesses through local industry-academia-government collaboration, and providing technology-backed products and services. The company's core offerings include small-scale incinerators for medical waste (notably the NU-100/100B model), solar power generation systems, and international trade consulting. Its primary customers and partners include the World Health Organization (WHO), the Japan International Cooperation Agency (JICA), Toshiba Corporation's Social Infrastructure Systems Company, Toyota Tsusho Corporation, Mitsubishi Electric Corporation, and Mitsubishi Electric Asia Pte Ltd (MEAP). Stella Environment has built a notable track record in international development projects, particularly in Pacific Island nations and Africa. Through its partnership with MEAP, it has supplied solar power systems to Niue (200kW), the Federated States of Micronesia (800kW), the Marshall Islands (solar LED street lights), and the Cook Islands (3.8MW). It has also supplied solar LED street lights to the Democratic Republic of the Congo and a solar power project in Tonga funded by Japan's Ministry of Foreign Affairs PEC Fund. Its medical waste incinerator, the NU-100B, was supplied to the Democratic Republic of the Congo under a grassroots human security grant aid project. The company is registered as a medical waste incinerator supplier to UNICEF (UNGM Registration Number 153167) and as a medical waste treatment provider to the FAO. Its technology is listed in the United Nations Industrial Development Organization (UNIDO) Tokyo environmental technology database. As of its latest company information, Stella Environment has a capital of 27.5 million yen and employs 7 people. It is a private company, not listed on any stock exchange.

Stella Environment Corporation was founded in June 2005 (Heisei 17) as a university-launched venture in collaboration with Nagasaki University. This origin reflects the company's early ties to academic research and local industry-academia-government cooperation, which remains a stated pillar of its founding vision. In June 2006, the company was selected for the Ministry of Economy, Trade and Industry (METI) Green Service Sizing Model Project. In September 2007, it was selected for METI's Collaboration Construction Support Project. These early recognitions helped establish the company's credibility in environmental services. A significant milestone came in May 2008, when Stella Environment was registered as a supplier of medical waste incinerators to UNICEF (UNGM Registration Number 153167). This registration opened doors to international humanitarian procurement. In June 2010, the company was registered as a medical waste treatment provider to the Food and Agriculture Organization (FAO) of the United Nations. From 2012 onward, Stella Environment expanded its international project portfolio, particularly in renewable energy. In September 2012, in cooperation with Mitsubishi Electric Asia Pte Ltd (MEAP), it won an order for a 200kW solar power project for Niue. In November 2013, again with MEAP, it secured an 800kW solar power project for the Federated States of Micronesia and a solar LED street light project for the Marshall Islands. In November 2015, it won a 3.8MW solar power project for the Cook Islands, also with MEAP. In December 2015, it received an order for the NU-100B incinerator for the Democratic Republic of the Congo under a grassroots human security grant aid project. In June 2016, it won a solar LED street light project for the Democratic Republic of the Congo with MEAP. In December 2016, the company's technology was registered in the United Nations Industrial Development Organization (UNIDO) Tokyo Investment and Technology Promotion Office's environmental technology database. In April 2017, it undertook a solar power project in Tonga funded by the Ministry of Foreign Affairs PEC Fund, aimed at improving socio-economic productivity in rural and remote island areas. As of the latest available company information, Stella Environment is headquartered in Minato-ku, Tokyo, with capital of 27.5 million yen and 7 employees. It maintains relationships with major organizations such as WHO, JICA, Toshiba, Toyota Tsusho, and Mitsubishi Electric. The company remains a small but active player in the niche market of environmental technology for international development.
