Facility Design & Start-Up
- Development of a Privatized Source-Separated Food Waste and Separate Biosolids In-vessel Composting Facility, for the Town of Hanover, NH and Dartmouth College. Providing technical assistance for 25-ton-per-day facility design, permitting requirements, development of cash flow projections, debt/equity needs assessment and facilitating location of potential equity investors, construction management and assessment of first year of operation. Facility Co-designer, Air Treatment Biofilter Designer, Construction and Shake-out Operations Manager.
- Yard Waste Recovery Facilities, for Newton & Springfield MA and Nashua NH. Incorporated an assessment of material delivery volumes, site sizing and compost-pad design, operating procedures, equipment acquisition and monitoring protocols. It included development of an operations manual, staff training and oversight of operations start-up. Was subsequently on-call for trouble-shooting operational challenges.
- Compost System Design to Incorporate Grass, for the City of Temple Terrace, Florida, design of a wet-season -- dry-season municipal scale composting methodology to accept large volumes of high-nitrogen grass waste. This was accompanied by a proposed curbside collection strategy and related cost analysis. Designer, Trainer and Author
- Design & Construction of Odor Biofilter and Redesign of Composting Methodology. For Dartmouth College, Hanover, NH. To revamp and upgrade an institutional composting process and the associated odor controls so to compost food waste, paper products and manures through active, static aerated composting methodology. Analyses include changes in porosity, density moisture content oxygen consumption through the two stage composting process as well as determining stability of the final compost product. In addition, the project requires the design and installation of a biological filter to treat process air from the active composting bays. The client was left with an operator’s manual for both the composting and biofiltration process. Designer, Researcher and Author
- Materials Diversion Analysis for Dartmouth College’s Food Services, under a grant from the American Forests and Paper Association. To determine materials collection and diversion strategies from disposal, as well as assessment of internal procurement and operations to enhance waste minimization. This analysis included the net impact of biological demand to waste water streams from in-sink food disposals. Research Design, and Co-Author
