Environmental engineers in Germany are designing portable lavatories which can produce energy out of methane produced by human excrement. The energy can then be used to light up the camps at night for better safety and for cooking meals without relying on limited fuel supply or firewood.
Refugee camps typically house thousands of people in a small space of land, where energy shortage and poor sanitation are common problems. According to the UN Refugee Agency (UNHCR), some 2.4 million people around the world are currently living in about 300 refugee camps. Averaged-sized refugee camps hold about 20,000 people.
