Design of a plant for reduction and reuse of construction and demolition waste (CDW), in South Lima, based on Reverse Logistics

The design of the proposed reuse and recycling plant is based on the guidelines of reverse logistics, which propose the analysis of different strategic decisions to achieve optimal design of the production system for obtaining recycled aggre-gates from construction and demolition waste (CDW) with inadequate final disposal. The increasing volumes of the generated CDW has led to the formation of landfills at destinations that do not have the conditions for waste collection; further, optimal treatment of this type of waste is not achieved, and the number of in-formal dumps has increased, thus affecting social and environmental surroundings (morbidity rate, concentration of greenhouse gases, and atmospheric dust). Additionally, the proposed design will reduce the exploitation of deposits or quarries to obtain natural aggregates, avoiding the depletion of natural resources, and will supply part of the market that is currently undersupplied. Finally, the proposed plant will be validated through a small pilot test to confirm that the product obtained at the end of the process complies with the parameters to be marketed as an ingredient for the concrete mix.
