Waste collection can be a lucrative business with benefits for the entire community. With the support of WaterAid, Mattius Millinga has a thriving waste collection business in his village in Tanzania. Using a gulper – a simple, clever waste extraction machine – he collects waste from his community and treats it at a faecal treatment plant he built beside his house. For the community, Mattius’ service means pit latrines don’t overflow and spread disease, but additional benefits include the gas created from the waste treatment which his family can use to cook with!
