Title:Surface Modified Fly Ash For Value Added Products (Sumo Fly Ash)
Author(s):Chandrasekar, Sriraam
Subject(s):Coal fly ash -- Beneficial reuse
Waste utilization
Coal combustion residue
Abstract:Project Description The primary objective of this project is to advance the development of technology for synthesizing sulfurized vegetable oil modified (SuMo) fly ash particles with inherently reduced metal leaching for use as novel fillers in multi polymeric matrices. It will be demonstrated that these encapsulated fly ash particles will improve functional properties of plastics and elastomers and have comparable or improved environmental release of constituents of potential concern (COPC) compared to non-CCR (coal combustible residuals) products, thereby meeting EPA evaluation criteria for CCR encapsulated beneficial use. R&D under this FOA is intended to increase the beneficial use and advance the management of CCR, thereby reducing the volume of CCR needed to be disposed of in impoundments while protecting the environment and the health and safety of the public. In light of the recent CCR rulemaking, projects funded under this FOA must perform R&D to address a technology gap that would economically achieve an objective as described in one of the two areas of interest (AOIs). In particular, sulfurized vegetable oil coated fly ash particles would provide both economic and functional benefits as a polymer filler, as they have improved mechanical properties and lower cost in comparison to traditional organic filler.
