Humans generate millions of tons of waste every day. This waste is rich in water, nutrients, energy and organic compounds. Yet waste is not being managed in a way that permits us to derive value from its reuse, whilst millions of farmers struggle with depleted soils and lack of water.
Most of the domestic and agro-waste in African cities end up in open dumps and natural water bodies thus causing severe environmental and health problems. These waste streams have resources such as nutrient and energy that can be valorized by transforming them into valuable products.
