Back to Earth: Composting for Various Contexts

With organics making up more than 50% of solid waste in Asia, managing this waste stream will have a huge impact on waste management and the reduction of methane emissions. 

With superb illustrations and easy-to-follow instructions, “Back to Earth” encourages people to explore every facet of composting: whether in a sprawling backyard or in a limited space such as a high-rise apartment, composting can be customized to suit any situation.
