Tojo Gas Co., Ltd. is pleased to announce that the "Technology Demonstration Project in National Parks" commissioned by the Ministry of Land, Infrastructure, Transport and Tourism was completed on June 22. ■ 'Smailet' Selected for Demonstration Project in National Parks Tojo Gas Co., Ltd. handles the sales and after-sales support for 'Smailet,' a self-contained water recycling toilet manufactured and developed by Sumitomo Mitsui Construction Co., Ltd. The "Technology Demonstration Project in National Parks," which has now been completed, was a public call for proposals aimed at realizing sustainable management and enhancing the appeal of urban parks, and promoting the introduction of advanced technologies and initiatives to national parks. Our company aims to contribute to the sustainable management and enhanced appeal of national parks. We proposed 'Smailet,' a self-contained water recycling toilet that allows visitors to use restrooms comfortably even in locations without adequate water and sewage infrastructure, thereby enhancing the park's attractiveness. This proposal was adopted by the Tohoku National Government Park Office, and we have now installed the water recycling toilet 'Smailet' in the National Park Michinoku Mori no Kohan Park, managed by the same office, to conduct a demonstration project. During the demonstration, we surveyed the needs of many visitors of all ages who used the facility at the national park, and also conducted a demonstration using an LP gas generator powered by LP gas, which is our core business.
