A Sustainable Integrated Solution from waste to Civil Construction

Abstract

Solid waste generation typically consist of human activities, which is generalized by term Municipal Solid Waste (MSW) that covers household and commercial refuse, consisting of degradable (paper, food waste) partially degradable (wood, and sludge) and non-degradable materials (leather, plastics, glass) MSW. If not disposed properly this can cause various environmental, social, and economic problems. First world countries adopt the Municipal solid waste system (MSWM), developing countries like Pakistan still follow a Linear Waste Management approach by dumping waste at landfill sites without classification or recovery for reuse. This approach differs from MSWM adopted by developed countries, which classifies, separate and process most of the waste for reuse while dumping only the fraction of it at landfills. With growing population in Pakistan and less land to go around, arises the need to study the possibilities arises. This study is designed to investigate local processing options such as using plastic, and reclaimed asphalt and building material for tuff tiles which result in 29.25 percent gain in compressive strength from reference cement-aggregate tuff tile, while using 15% replacement of coarse aggregate, e-waste in concrete showed 6.4% decrease in strength but 10% decrease in weight from reference cylinder which open window for light weight and earthquake resistant construction, using paper & cardboard slurry with recovered structural elements for concrete production the strength decreases but it can be used in non-load bearing elements; Machine Learning approach was develop between all 25 experimented tested mixes means 75 samples. This were adopted at campus level by a smart automatic bin system complimented by mobile application for achieving a Zero Waste Campus allowing for efficient collection of waste leaving the system with a possibility to be scaled up for local or national level.
