It is often said by those who work in development that simply improving sanitation around the world could effect huge change. More than a third of the global population doesn't have access to clean safe toilets and running water. In the Kenyan capital Nairobi, a new project is turning waste into useful organic products. The BBC's Nancy has this report.
Stanley washes his hands in a reluctant stream of water pouring out of a tap molded onto a small white plastic drum. We're standing next to one of the toilets he operates charging less than one US cent per use. It looks freshly painted, a bright blue with white and yellow branding conspicuous in these otherwise grey muddy part of Mukuru, an informal settlement in Nairobi. He says the toilet has changed much more than just the landscape.
There used to be a lot of wastes.
Stanley's is one of more than seven hundred so-called "fresh life toilets" in Nairobi's urban settlements. They are made by the company Sanergy as part of a fresh approach to old problems. By linking a shortage in proper sanitation facilities to a shortage in local fertilizer, the hope is to create one solution for two problems. At the company's workshop a carpenter is making doors for more toilets. All the toilets made here are waterless. There is no need for water to flush with. Sawdust is used instead. This compensates with a lack of piped water in the settlements and helps with the next step, a crucial step treating the waste.
These people produce over ten thousand tons of waste every day.
I'm standing in the treatment facility where all the waste collected from the "fresh life toilets" is brought. All around me is piles of treated waste. Now this is the final stage before it's packed and then sent off to different trial farms across the country.
Sanergy treats about twenty-five tons of waste each week. But as Sara explains, getting people used to the idea of products from human waste is taking some effort. And fertilizer isn't the only byproduct. No waste is wasted here. Some of it is fed to the larvae of black soldier flies who remove the pathogens and turn the waste into protein, producing a nutritious feed for animals. The reusing of waste benefits the environment.

史丹利在一个安在白色塑料小桶的水龙头边洗着手，水流非常不顺畅 。我们正站在他经营的一个厕所旁边，该厕所的收费标准是每次不到1美分 。厕所看起来是刚喷的漆，鲜艳的蓝色搭配黄白相间的商标在内罗毕非正式小村落穆库鲁灰色泥泞的环境中非常显眼 。他说，厕所改变的远不止当地景观 。
内罗毕城市居住区有700多家所谓的"新鲜生活卫生间"，史丹利开的就是其中一个 。这些洗手间是由Sanergy公司制造的，作为一种解决老问题的新方法 。把缺乏适当的卫生设施和缺乏当地肥料这两个现实联系起来，希望可以一箭双雕 。在该公司的车间里，一位木工正在为厕所造门 。这里生产的厕所都是不需要水的，冲厕所不用水，而是用锯屑 。这弥补了聚落缺乏自来水的情况，也有助于下一个步骤，一个关键步骤--处理废物 。
我现在站在处理厂中，从"新鲜生活卫生间"收集的所有废物都带到这里 。我身边是成摞的已处理过的废物 。现在是最后一个阶段，这个阶段过后垃圾将被打包送到全国各地的试验农场 。
Sanergy每周大概处理25吨废物，但萨拉解释说，在让大家接受人类排泄物做成的产品这样的概念上还需要花费一些精力 。另外，肥料不是唯一的副产品 。在这儿，一点废物都没浪费 。有些用来喂养黑水虻的幼虫，黑水虻能去除病原体，把废物转化为蛋白质，成为动物的营养饲料 。废物再利用对环境有益 。
