WTS is proud to announce that we were presented with the Responsible Care Partner Sustainability Award at ACC’s 2025 Responsible Care® Awards Program. Our project, Finding Creative Sustainable Solutions for Difficult-to-Recycle Materials, highlighted our strategic and impactful efforts in beneficial reuse and resource conservation. As a non-asset-based waste and byproduct management provider, WTS focuses on identifying the most sustainable end-of-life solutions for challenging materials that are difficult to recycle. In 2024 alone, we directed over 33 million pounds of waste into more sustainable applications, including fuels blending in cement kilns and alternative (AEF) programs. We also diverted over 77 tons of calcium fluoride sludge from landfill, repurposing it as a supplementary cementitious material. These efforts not only help clients lower disposal costs and reduce landfill dependence but also contribute to lowering the greenhouse gas emissions associated with cement production—an industry responsible for 8% of global GHG emissions.
WTS’s sustainability initiative is built on rigorous supplier vetting, close client collaboration, and strategic market research using EPA e-Manifest data. By continually expanding our supplier network and adapting logistics to client needs, WTS has enabled the responsible reuse of complex waste streams including plastics, solvents, and industrial sludges. WTS sees great potential for expansion, particularly in increasing AEF use and sourcing supplementary cementitious materials from non-traditional waste streams. Though the percentage of AEF used in cement kilns is growing, currently sitting at about 16% of the industry’s fuel mix, there is clearly room for growth here and opportunity to supplant virgin fossil fuels.
