比尔·盖茨非常重视厕所。实际上，他非常致力于这样的事业，以至于他甚至启动了中国重新发明的厕所博览会，并从不需要水或下水道的新厕所中取出了面纱，并依靠化学药品将人类废物转化为肥料。
During the speech, Gates said, ‘We are all here for one reason: because more than half the world’s population doesn’t have the safe sanitation they need to lead healthy and productive lives.’ Gates also tweeted a video on Monday that detailed his and the mission of his foundation to improve the sanitation for the countries that currently do not possess and are unable to afford the sewer infrastructure require for removal of waste.
他在北京的主题演讲时随身携带了一罐粪便。他说，‘您可能会猜测这个烧杯中有什么，您会说对了。人类的粪便。这少量的粪便可能包含多达200万亿轮病毒细胞，200亿个志贺氏菌细菌和100,000个寄生虫卵。’他将罐子带到讲台上大约十分钟，然后再清除。
卫生条件不佳是每年五岁以下约50万儿童死亡的原因，由于健康成本较高，生产率和工资损失，每年约有2230亿美元。未经处理的污水也会对周围环境产生负面影响。盖茨说：“一些未经处理的人类废物是在无衬里的厕所中，这些厕所污染了人们在房屋周围的地下水。有些是手动收集的，或者是卡车，并被倾倒到附近的水域或水体中。有些是在下水道中收集的，但从未得到治疗。关键是，我们远非2015年全世界使用安全管理的厕所的目标。’
博览会在比尔·盖茨（Bill Gates）的话语中的目标是“推出新的创新，分散的卫生解决方案，这些解决方案将使全球数百万人民受益。”这些重新发明的厕所目前正在南非德班（Durban）进行测试。Gates said, ‘Durban is a good place to run these tests because the city is growing fast and many people there don’t have modern sanitation, which means that, even if they have access to a toilet, the waste can get into the environment and make people sick. A typical toilet needs water, but many of the new approaches don’t require any water at all, some of them don’t need electricity either, others run on solar power. All of them remove the pathogens from the waste, and, most importantly, they don’t have to be connected to the sewer system.’
出色的发明，不仅是环境，而且是人类免于疾病和死亡的措施。很好的主意
