The City of Columbus, Ohio was planning for capital improvements at it’s two large wastewater treatment facilities. As part of the improvements, a solids master planning effort was undertaken. The master plan employed the “triple bottom line” approach in assessing several different technologies and strategies in planning for future biosolids management practices such as incineration, composting, land application of Class B, and landfill disposal. Material Matters analyzed the current land application program practices and established baseline for all operating parameters. Available technologies and approaches for Class B liquid and cake biosolids were outlined and an assessment was made as to the benefits and challenges of each option. We also assessed the environmental impact of biosolids land application programs in terms of greenhouse gas emissions and energy consumption associated with specific practices. Material Matters developed an approach for managing and marketing various products and calculated land application (present worth) costs associated with various beneficial use management methods over 20-year period.
During the first planning meeting of Howard County's Master Solids Planning project, County personnel established the project's main objective - to select a biosolids technology that would produce a high quality, versatile, regionally demanded product. In turn, this goal would be the principle evaluation criterion throughout the technology selection process. With this in mind, Material Matters was tasked with researching Maryland's increasingly stringent biosolids regulations, identifying beneficial use markets pertinent for the region, and conducting phone and on-site interviews with potential beneficial users. The information we gathered during the regulatory and market research phase, in turn, assisted the County to select a technology that, although not highly favored at the start of the project, was most appropriate to meet the County's goals..
As part of a planning effort for the San Francisco Public Utilities Commission’s (SFPUC) upcoming major biosolids treatment and handling capital improvement projects, Material Matters teamed with AECOM / Parsons Joint Venture to complete an assessment of the biosolids beneficial use markets in California's Bay Region. Material Matters identified potential biosolids beneficial use markets in the region, and conducted a thorough market evaluation using phone interviews and site visits to determine the long-term viability, capacity, costs, and preferred product characteristics of each market. The market assessment provided SFPUC with a set of viable beneficial use market options, including innovative beneficial markets such as soil blending and biomass production.
