近年来，加拿大、芬兰等地的多家公司致力于开发无水生态厕所。ekolet公司在今年最新推出的Happy-Loo堆肥式马桶，无需水、下水或电力系统，且安装和使用更为简易。通过可置换的过滤材料分离固体与液体废物，最终可将人类排泄物转化为肥料。早在1985年，瑞典生态专家Uno Winblad提出了免水生态厕所的设想，要求这类新产品具有卫生功能的同时，更要生态友好。免水生态厕所要达到“零污染、零感染、零废弃物排放”和“减量化、无害化和资源化”要求。在日益重视环保的中国，堆肥厕所也受到关注。北京海淀区双榆树公园旁建有中国第一座节水、节能、无臭、并不断输出有机肥的新型城市堆肥公厕，平均每蹲位年节水400吨。在中国的新农村建设中，这种厕所的使用也越来越广泛。

Technology | The waterless composting toilet promotes the green lifestyle

In recent years, many companies in Canada, Finland and other places have devoted themselves to developing waterless eco toilets. Ekolet's newest Happy-Loo composting toilet this year does not require water, sewage or power systems, and is easier to install and use. The separation of solid and liquid wastes through replaceable filtration materials can ultimately convert human excreta into fertilizers. As early as 1985, Uno Winblad, an expert on Ecology in Sweden, put forward the idea of "water free eco toilet", requiring that new products are with the features of sanitation and more eco friendly. The "water free ecological toilet" should meet the requirements of "zero pollution, zero infection, zero waste discharge" and "reduction, harmlessness and recycling". With the increasingly importance of environmental protection in China, composting toilets have also attracted attention. Beijing Haidian District Shuangyushu park built beside the Chinese first water and energy saving, odorless, and continuous output of organic manure compost new city public toilet, the average annual saving 400 tons of water each toilet stall. In China's new rural construction, the use of this toilet is also more and more widespread.
