Abstract |
Construction and demolition waste (CDW) left at landfill sites increases the burden on landfills, which are increasingly becoming scarce. The United States Environmental Protection Agency (US EPA) estimates that out of the 169 million tons of mixed CDW generated in 2014, only 38% of it was recycled. In North Dakota, CDW generated is disposed of at the landfills. This CDW disposal practice hampers the realization of value from construction and demolition waste. The objective of the study was to assess current practices and apply life cycle assessment (LCA) and life cycle costing (LCC) to evaluate the benefits of two CDW management scenarios. The study found that a 75% reduction in the CDW sent to the landfill can reduce the environmental burden by 35%. Furthermore, replacing raw materials with recycled materials creates net environmental savings by preventing the production of raw or virgin materials. This practice can reduce the environmental burden by 25%, while generating an income of $61/ton for the city. The results of this study provide information on the value of recycling CDW and serve as a basis for decision-makers to rethink CDW waste management practices in North Dakota. |
