performance of structural concrete using waste to energy wte Combined Ash
2020Co-Authors: Yixi Tian, Athanasios Bourtsalas, Shiho Kawashima, Nickolas J ThemelisAbstract:Abstract In the U.S., about 27 million metric tons of municipal solid waste are used as fuel in Waste-to-Energy (WTE) power plants, generating about seven million tons of mixed bottom Ash and fly Ash (Combined Ash) annually, which are disposed of in landfills after metal separation. This study assessed the effect of using Combined Ash as a substitute of mined stone aggregates on the mechanical properties and leachability of cement mortar and concrete. The as-received Combined Ash was separated into three fractions: fine (

critical examination of recycled municipal solid waste incineration Ash as a mineral source for portland cement manufacture a case study
2019Co-Authors: Linda Monroy Sarmiento, Kyle A Clavier, Jerry M Paris, Christopher C Ferraro, Timothy G TownsendAbstract:Abstract Municipal solid waste incineration (MSWI) Ash has the potential to be used as mineral feed for portland cement manufacture but is not currently used in this manner in much of the world. A scoping study was performed using samples and data from Florida, US, to assess the potential magnitude of material that may be recycled to create a viable clinker. Results indicate that MSWI Ash possesses the elemental ingredients to serve as a partial kiln feed replacement. Large amounts of MSWI can be used based on mineralogy alone, but chloride and alkali content limitations decrease allowable replacement amounts, especially for fly Ash. Average allowable replacement percentages that did not exceed standard chloride and alkali limits were 6.4%, 0.33%, and 1.17% for bottom Ash, fly Ash and Combined Ash, respectively. MSWI bottom Ash may be the preferred material stream in the absence of pre-processing techniques such as wAshing. The scoping study found that available MSWI Ash could supply a large amount of the current kiln feed demand, and a feasibility and cost assessment supports that both MSWI facility and cement kiln operators have justification to pursue this technology with more detailed evaluations.
