Final answer:
Solid waste reusability primarily depends on the composition of the resulting ash and the market demand for recycled materials. Clean ash can be used in construction or as landfill cover, but market fluctuations heavily influence recycling viability.
Step-by-step explanation:
Whether or not solid waste can be re-used depends on multiple factors, but in particular, it upon the market for it and the composition of the ash. In scenarios where the ash produced is relatively uncontaminated and devoid of harmful compounds, it can be recycled for various uses such as MSW landfill cover or in the construction of roads and artificial reefs. However, the existence of a market for the recycled material is crucial; such markets can fluctuate, often influenced by economic cycles. For example, recession periods can severely impact the profitability and feasibility of recycling endeavors. Municipal solid waste (MSW) may include a spectrum of waste types, from biodegradable to hazardous waste, excluding industrial, agricultural, medical waste, radioactive waste, and sewage sludge. The focus for MSW is often on reducing, reusing, and recycling in order to minimize the environmental impact and the amount of waste sent to landfills and incinerators, promoting a safer and cleaner environment. Overall, reusability of solid waste is a complex issue that rests on the quality of the resulting ash, the costs associated with recycling, and the demand for recycled materials.
