[daydream believer] Sanitation and wealth in rural area of Indonesia

Our biogas digesters allow farmers to add manure from their cows and pigs to produce biogas and organic fertiliser. In other words, it is also a sewage treatment plant in the sense that it treats manure. In Japan, they have an advanced decentralised sewage treatment system called a Jyokasou. If human waste is treated in Jyokasou, there is no need for large sewage treatment plants. In less densely populated areas, centralised sewage treatment plants are not cost-effective, so like our biogas digesters, this Jyokasou is a very effective system.

According to data from 2013, nearly 40% of the poorest 20% from the bottom live in toilets, and around 20% live in simple toilets in Indonesia. In the next 20% of the poorest households, about 20% live without a toilet while the wealthiest households have almost no toilets at all. There's a big connection between poverty and toilet problems. In this case, the solution is either to provide toilets to the poor or increase the poor's economic wealth - the former is a short-term solution, the latter a long-term solution.

While poverty is relevant to many of the SDGs, there is a big difference between developed and developing countries regarding toilets. In developed countries, poverty and toilets are not as pronounced a problem. In other words, the sooner we solve the toilet problem, the better.
