Green Manufacturing of Eco-Materials by Urban Mining from Landfill Dump Site

Abstract:

Waste that was generated by human activities needed to be treated properly in order to reduce harmful to environment. At present, landfill is the most common treatment method of Municipal Solid Waste (MSW) all over the world, due to it’s lowest net treatment cost when comparing with the other methods, i.e. thermal treatment and composting. However, it is quite clear that the landfill method is not an ultimate and sustainable way for the MSW treatment. Indeed, it works in such a way that the waste would be transferred into land and waiting for final disposal process in the future, causing a large land usage and long-term treatment. But still, there are a lot of valuable materials that needs to be reclaimed inside the dump waste. Green manufacturing of Eco-Materials from Landfill Dump Site by urban mining has been developed. The pilot reclaiming landfill has a daily capacity of 50 Tons, by using land excavation and passing through trommel screen and magnetic separation. The reclaim materials consist of non-degradable plastic, metal, glass and soil. Metal and glass have been used for recycling purposed. The non-degradable plastic has a proportion around 35% of reclaim materials in the form of Refuse Derived Fuel (RDF) and shall be used for green and clean energy to produce electricity by using gasification technology. This research described the green manufacturing process of urban mining to get the valuable eco-materials. The results shown that the new and eco-materials from landfill dump site can be used as clean and green energy that helps reduce the global warming effects and impact to environment.
