Non-hazardous industrial waste (NHIW) includes industrial processing residuals such as iron and steel slag, combustion ash, foundry sands, pulp and paper mill wastes, industrial wastewater sludge, and a variety of other materials not subject to hazardous waste regulations. This is a pervasive and important waste stream, not least because many of its constituents have been demonstrated to be useful substitutes for raw materials throughout the economy. In the United States, there is no regular process for assessing the quantity and composition of NHIW generated each year, information vital for any systematic strategy of environmentally-beneficial recovery and reuse. To fill this data gap (which stretches back over three decades), Yale researchers developed a triangulation approach to waste accounting that synthesizes results from multiple independent estimates. Beneficial use pathways were then identified to assess potential beneficial use of the quantified waste streams.
This webinar will share the recent findings from this EREF-funded project. Results from this project will strengthen the path for the waste management industry to be a key facilitator of and participant in large-scale reuse and recycling of NHIW.
