Landfill mining dominated by organic solid waste: a review on its benefits, potential and challenges to recovery landfills in growing cities in Indonesia

Abstract

Abstract One of serious impacts of increasing human population in cities is the availability of land, strategic land in particular becomes rare and as a result, its value increases rapidly. Another impact is the amount of solid waste produced which also continues to increase sharply. Although the perception and knowledge of the community regarding solid waste is improving, it does not necessarily change their paradigm, mindsets and behaviors in minimizing solid waste, the landfill is still the final solution to solid waste. In general, the carrying capacity and supporting capacity of landfills in the cities have reached the maximum limit and must be closed immediately. Initially the locations of the landfills were far from city centres, but now generally they are in densely populated urban areas. Procurement of new landfill is constrained by regulations, costs, technical and social issues. NIMBY syndrome (not in my back yard) is the culmination of public rejection, and has even become a vertical conflict between the community and the government. The study of landfill mining, particularly the study of benefits, potential and challenges in choosing landfill mining, which is dominated by organic solid waste, is an interesting study to explore. The use of compost landfill mining as an organic fertilizer for plants, or as biocover is a logical argument for recover or extend the service life of old landfill.
