in the philippines, much of the country's municipal solid waste is disposed of in open dumps or in bodies of water near urban areas. as a result, the environment surrounding the dumpsites is heavily impacted and a source of concern for human and environmental health. often, over half of the waste is organic, and another significant portion is composed of material resources that could be recycled. knowing that the philippines has a growing population that is proving difficult to adequately feed, what waste management approach could help in this problem?
