Recover and reuse
The number of people living in urban areas finally surpassed rural populations in 2014. By 2030, an estimated 4.9 billion people will inhabit urban areas. Urbanization is putting pressure on already strained water and land resources, creating competition between the urban and agricultural sectors. On the other hand, resource recovery and reuse technologies can convert waste into valuable resources, such as fertilizer, fuel or feed, that benefits farmers, create jobs and generates business opportunities. The solutions below focus on reducing the growing environmental footprint of urbanization by identifying, testing and promoting practical solutions on recovery and reuse of water, nutrients and energy, which is currently lost through poor urban waste management.
