TRANSCRIPT
III. NEXT STEPS Based on the context and recommendations provided in this document, each relevant UNH stakeholder should review the recommendations relevant to him/her, assess the feasibility of each action item, and identify any obstacles or barriers that have not been mentioned or accounted for in this report. Before taking action on any recommendations but after stakeholders have reviewed relevant items, the Zero Waste Task Force should schedule a meeting to discuss this report’s recommendations and develop a more specific timeline against which to work towards the following five prioritized action items, which should be discussed in greatest detail:
1. Develop clear and concise values, mission statement, and specific zero-waste goals for the Zero Waste Task Force and for UNH as an institution.
2. Hire an individual to serve as the UNH Zero-Waste Manager. 3. Develop and implement a Green Procurement Plan. 4. Select and pursue an alternative food waste management strategy. 5. Begin inventory of indoor waste bins and infrastructure.
Becoming a zero-waste campus will require significant work. Figure 2.6, borrowed from General Motors’ zero-waste business blueprint, provides a general checklist against which UNH can compare its own progress. The image presents opportunities for comparison. For example:
• Although UNH tracks waste data, collection and data management processes require improvement.
• UNH lacks an institutional definition of “zero waste.” Without specific reduction and diversion goals and timelines, the concept of a zero-waste campus remains nebulous and little progress will be made.
• Campus stakeholders have improved educational and community engagement efforts over the years, but the University still lacks a fully-supported “sustainability culture.”
• Regulatory and policy barriers—like those related to procurement and surplus mentioned in this report—can hinder zero-waste initiatives and require revision if UNH is to reach its waste-reduction goals.
Figure 2.6. A zero-waste checklist blueprint.
As a large academic institution at the forefront of sustainability, UNH carries a responsibility to further develop and make significant progress towards its zero-waste goals. Reducing campus waste can result in financial savings, help the University reduce its carbon footprint, and instill greater sustainable values in the UNH and Durham communities. To achieve these results, the University must prioritize reducing food waste and improving campus food waste management, establishing and installing standardized waste infrastructure, and amending administrative policies and procedures to promote sustainable waste reductions. Pursuing waste-reduction initiatives may require significant financial and physical resources and necessitates consistent and clear communication among stakeholders. Historically, many waste-related decisions and projects at UNH have been made and initiated by independent parties, resulting in confusion and a complex web of disparate initiatives. Future success will depend greatly on sustained cooperation and collaboration among numerous campus departments, academic offices, and non-University stakeholders. By addressing waste issues more comprehensively on an institutional scale and communicating barriers and best practices with the community throughout the process, UNH will undoubtedly make progress towards a zero-waste reality and remain a sustainably-minded collegiate institution worthy of the recognition it receives.

APPENDIX: FOOD WASTE MANAGEMENT AND COMPOSTING ALTERNATIVES Option 1: Cover the Existing Windrow System at Kingman Farm To reduce pest presence and ease waste additions during cold winter months, the windrows at Kingman Farm could be covered with a ClearSpan structure. The structure would be sized to 70 ft. by 56 ft. and cover three existing rows. Fresh organic waste should be added to covered windrows; windrows containing curing compost would be less likely to attract pests and thus do not necessitate cover. Covering the actively-composting windrows would eliminate the seagull issue, as well as the challenge of adding new food waste to frozen or snow covered rows in winter. The solar radiation provided by the ClearSpan fabric would maintain a warmer temperature inside the facility sufficient to keep the piles from freezing. If the structure is appropriately sized to accommodate a tractor lane, existing Kingman machinery (i.e., windrow turner, tractor) could continue to be used. Even if UNH installs a covering structure for existing windrows, improved management is necessary. In order to properly break down, new food waste must be mixed with spent bedding and manure before being covered. Under proper management, the food waste should be adequately mixed with bedding (which may require slightly more labor—about 5-10 additional minutes per waste addition) and covered with a layer of finished compost that acts as a biofilter and to reduce odor. Covering the Kingman windrows would not eliminate existing capacity concerns, nor would winter plowing and road access challenges be ameliorated. Option 2: Relocate and Cover the Windrow System For optimal performance and minimal pest presence while maintaining the windrow composting system, the windrows could be relocated to and constructed in a covered facility. An ideal facility would be built on a concrete floor (variations below), covered with ClearSpan fabric, and house windrows and the tractor and windrow turner. The structure would be sized according to daily quantity of waste generated from campus dining halls and the width of the tractor and compost turner, and would house two or three four-foot-high windrows, one or two center driving lanes, and two rows of waste blocks located between the ClearSpan walls and the outer edge of the windrows. Waste blocks serve to tether the structure in place and protect the fabric from any possible damage from the compost turner. Structures could be built in one of two possible sizes: 120 ft. by 35 ft. or 70 ft. by 56 ft. The larger (120 ft. by 35 ft.) structure would feature one central tractor lane flanked by two 120-foot-long windrows. The smaller structure would contain two tractor lanes—one on each side of a central windrow—and two additional windrows constructed along the waste blocks on the structure’s 56-foot-long edges. Each waste block row would measure two feet wide and be stacked two blocks high for a height of 4 ft. In the larger structure, each windrow would run on a 28-day cycle: food and animal waste would gradually be added to one row over a 14-day period, after which the second windrow would be built in the same manner. The first windrow would cure and compost during the 14 days in
which the second row is constructed, and when the second row has been completed, the first row’s contents would be relocated to an outside windrow for further curing. Thus, 28 days elapse between the initial waste additions to the first windrow and the removal of this material from the covered structure. In the smaller 70 ft. by 56 ft. structure, the windrows would collectively function in a 21-day rotation, with each windrow accommodating seven days worth of organic waste. After curing in the indoor windrows for 21 to 28 days, the compost would be relocated to outside windrows for curing for a few months at minimum. A large enough open area outside of the facility would be needed to create windrows for curing compost and to store bedding material. One outdoor windrow should be designated specifically for non-food waste; this would require no additional management and reserve space in the indoor rows for food waste. Covering the actively-composting windrows would eliminate the seagull issue, as well as the challenge of adding new food waste to frozen or snow covered rows in winter. The solar radiation provided by the ClearSpan fabric would maintain a warmer temperature inside the facility sufficient to keep the piles from freezing. This option would continue to make use of the machinery (i.e., windrow turner, tractor) purchased for managing the Kingman operation. Even with these infrastructural changes, improved management is necessary. In order to properly break down, new food waste must be mixed with spent bedding and manure before being covered. Under proper management, the food waste should be adequately mixed with bedding (which may require slightly more labor—about 5-10 additional minutes per waste addition) and covered with a layer of finished compost that acts as a biofilter and to reduce odor. Depending on the location of the new facility, this labor addition may be completely offset (or more) by reduced transportation time and costs necessary for staff to travel to the Kingman facility. If the structure is located at or near the campus equine facility, transportation will be even further reduced, as the manure and bedding will only require transportation over a very short distance.
UNH’s Woodman Farm (of which an aerial view is shown in Figure A1) is located essentially on campus, just northeast of the equine facility. Constructing a composting facility at this location would reduce the time and labor required to transport waste from the equine facility and campus dining halls.

Option 2a: Concrete floor with gravel driving lane. While any facility built under the specifications of the above option would require construction of the ClearSpan structure, constructing a gravel-floored facility would minimize total construction costs. Option 2b: Concrete floor. Alternatively, the facility could be built upon a pure concrete floor of 4, 6, or 9.5 inches in depth. Option 2c: Concrete aeration floor. The third flooring option for the facility is an aeration floor constructed of concrete with inlaid aeration pipes. The floor would require a depth of 9.5 inches of poured concrete to accommodate the inclusion of wire mesh and aeration piping. Building this floor in initial construction would allow for further development of an active ASP system in the future, if desired. Equipment required for active aeration beyond the aeration piping would cost approximately $15,000 (Smith, 2017). Option 3: Construct an Aerated Static Pile (ASP) System An ASP composting system differs from a windrow system in a few fundamental ways. Whereas windrows are shaped into long piles, an ASP system consists of a single compost pile. (Both windrow and ASP piles that contain food and animal waste can be built up to approximately four feet.) Many ASP systems are built upon aeration floors that contain pipe systems connected to fans and other machinery; this system draws air through the pile, providing valuable oxygen to the active microbes contained therein (US EPA, 2016c). ASP systems also require the addition of bulking agents—such as shredded paper or wood filings—to increase pore space and aeration capacity within the pile. While the compost pile in an ASP system can still benefit from being turned regularly, the primary cause of material breakdown is the active aeration provided by this piping-and-fan system. ASP systems compost food waste and other organic materials faster and more efficiently than windrows composting methods, but costs of establishing a system can be much greater. Shifting to an actively aerated ASP composting system would require more substantial construction and investment than Option 1. The system would require the construction of an aeration floor—ideally made of concrete inlaid with piping—for which labor and materials can be costly; a ClearSpan structure and waste blocks; and investment in aeration machinery, including fans or blowers, pile sensors, and a control system. The system would also require electricity to power this machinery and repeated purchases of woodchips to serve as a base layer between the aeration floor and the compost (Smith, 2016). Like the windrow system described in Option 1, an ASP system would benefit from a covering structure to deter seagulls and other pests, reduce odor, and minimize pile freezing in winter. After approximately 21 days in the ASP pile, organic material is sufficiently broken down and can be relocated to another pile (or windrow) for the “curing” and finishing phase with minimal risk of attracting vermin. This multi-step characteristic of the system would require that additional space—ideally located near the structure in which the ASP system is housed—be made available for curing windrows. Because organic waste breaks down much more efficiently and substantially in an ASP system than in windrows, however, the amount of land required for
the post-ASP curing windrows is smaller than the area currently occupied by composting windrows at Kingman Farm. An ASP system would require a shift in management practice and proper mixing, although the number of turnings required would be fewer. The site operator(s) would need to be trained to some degree, both in turning practices and aeration system technology and management. Depending on the location of the structure and the current amount of labor dedicated to managing the current windrow system, additional labor required for ASP system operations may be somewhat or completely offset by transportation reductions. Option 4: Install an Anaerobic Digester (AD) According to the American Biogas Council (2017), “anaerobic digestion is a series of biological processes in which microorganisms break down biodegradable material in the absence of oxygen.” Anaerobic digesters (ADs) process food waste and other compostable feedstocks more efficiently and rapidly than other composting processes (e.g., windrows) and produce two primary products—methane-rich (60-70 percent) biogas and digestate solids—the first of which can be used for energy, and the latter as a fertilizer-like soil amendment (University of Idaho Extension, 2014). ADs are commonly used to handle sewage sludge in wastewater treatment facilities and manure in livestock operations, but they can also be used as an alternative to composting food waste (American Biogas Council, 2017). The type and quantity of waste feedstock and the amount of energy available for use in the digester will determine the size, type, and cost of the most suitable anaerobic system. Wet fermentation digesters handle waste containing between 7 and 15 percent solid matter; this largely liquid waste is “pumpable” through the digester. Dry digesters handle waste comprised of 20 percent (or more) solids; these materials are generally not “pumpable” and are often stacked in the digester (McKiernan, 2015). Mixing feedstocks (e.g., liquid manure, food waste solids, etc.) to create a desirable consistency for wet fermentation is a common practice. Digesters also differ in their frequency of feeding. Batch digesters are the simplest systems, as they are fed with the initial feedstock and subsequently closed until the digestion process ends. In contrast, continuous systems can be fed at regular intervals during the active digestion process, thus providing more consistent and stable gas production than batch systems (MAPC, 2014). A third defining system characteristic is internal temperature. Mesophilic systems function at lower temperatures (around 95°F) and process waste more slowly, while thermophilic digesters typically run at temperatures around 131°F (MAPC, 2014). The biogas produced by an AD could benefit the University by serving as an additional fuel source for the campus cogeneration (co-gen) plant. The UNH co-gen plant is a combined heat and power system that provides energy to much of the Durham campus. The plant is served by the EcoLine, an HDPE plastic pipeline running from the Rochester, NH Turnkey Landfill to UNH that provides processed landfill gas (PLG) for the plant’s operations. The cogeneration process begins at the landfill, where raw landfill gas is pulled from the landfill, dehydrated, and processed to eliminate various chemicals and volatile organic compounds including hydrogen sulfide, siloxanes, and carbon dioxide (CO2). The complex gas-processing
(or “stripping”) process—which, along with processing plant maintenance, costs UNH approximately $3 million annually—is critical to obtain PLG that contains chemicals at levels the co-gen plant can safely and legally handle. Designed in 2006, the co-gen plant costs the University an additional $3 million each year in management and maintenance, excluding any additional external purchases of natural gas. The plant houses two reciprocating 20-cylinder engines that can operate using natural gas, PLG, or number 2 ultra-low-sulfur diesel fuels. Methane (CH4), a key ingredient in natural gas and PLG, is the primary fuel required by the co-gen plant, and ideal PLG for the plant contains 50 percent CH4. When PLG contains less than 50 percent CH4, which is common, the plant operators have two options: 1) they can mix the PLG with natural gas in an averaging tank to increase overall CH4 content of the fuel, or 2) they can increase the PLG volume and process out more CO2, which concentrates and increases the level of CH4 in the PLG. When the plant was constructed over ten years ago, the Turnkey Landfill produced approximately 13,000 scfm. Current production levels reach only 6,000 scfm, two-thirds of which the UNH co-gen plant receives. This significant reduction in gas production is due in large part to the decrease in municipal solid waste (MSW) generation that accompanied the Great Recession in 2007. Under the country’s depressed economic state, businesses and individuals reduced their purchases—and thus their wastes—of organic materials in particular, which reduced collective MSW and the gas this waste produced in the landfill. The UNH facility was not the only co-gen operation to receive PLG at levels far short of originally-modeled values; at a conference for the US EPA’s Landfill Methane Outreach Program, UNH utility systems manager Dave Bowley discovered that none of the other attendees was receiving the amount of landfill gas s/he had anticipated (personal communication, July 7, 2017). Although it has not been seriously considered in the past, an AD could greatly benefit the University by providing a more consistent source of gas for the co-gen plant—if organics and food waste generation continue at current levels—and a solution to the problems resulting from current composting practices. In this way, anaerobic digestion provides an appealing answer to the conflict clearly described in the WILDCAP report. At 60 to 70 percent CH4, the biogas produced by the digester would naturally be of a higher quality than PLG, and would likely require less processing before use (MAPC, 2014; D. Bowley, personal communication, July 7, 2017). The higher CH4 content of the biogas would also likely necessitate fewer purchases of natural gas to supplement incoming PLG. The digester could be connected to the existing EcoLine used to feed the co-gen plant, thus making use of existing infrastructure. Dartmouth, MA provides an example of such a connection: in 2014, a food-waste-processing AD was successfully adjoined to an existing landfill gas-to-energy facility, and positive results have motivated expansion of the facility (Barad, 2016). A few other educational institutions have successful renewable energy anaerobic digestion systems, namely UC Davis, Michigan State University, and UW Oshkosh. (See Supplemental Materials for information about UC Davis’s digester.) Unlike the existing windrow composting system or an ASP system, an AD requires more expertise and experience for proper management. Oversight and management of the digester
could potentially be incorporated into the responsibilities of co-gen plant personnel, provided the proper training. Consulting for and construction of the digester will likely be expensive, but the payback period for the project could be shorter than anticipated when including supplemental natural gas purchases in a cost-benefit analysis. From July 2016 to June 2017, the University spent $1.4 million on natural gas for the co-gen plant. Although some supplemental natural gas may still be necessary due to requirements outlined in the system manufacturer contract—and although the pricing market for natural gas fluctuates constantly—biogas from an AD could reduce University expenditures for this fuel source. Costs could also be recouped through future expansion of organic waste collection, if the University decides to offer this service to community businesses and other stakeholders for a tipping fee. It is currently unclear whether the existing gas processing infrastructure, located at the Turnkey Landfill, could be utilized for biogas processing. The windrow turner and tractor currently used for composting at Kingman Farm would not be used in this system, but could potentially be used for other purposes at Kingman or the University’s other agricultural facilities. Option 5: Contract Out Composting Services Hiring an external contractor to handle and compost campus food waste is a fourth possible option. Mr. Fox Composting, a composting company located in Portsmouth, NH, is the nearest commercial composting facility to which UNH could send its food waste and compostable serviceware. For commencement in May 2016, the University contracted Mr. Fox’s services, and the Athletics department plans to work with Mr. Fox during the upcoming football season. In July 2017, Rian Bedard (Mr. Fox’s chief composter) provided a cost estimate for handling food waste from the University’s three dining halls. Two main options exist: 1) UNH could collect and haul its organic waste to the composting facility, or 2) Mr. Fox staff could haul the collected waste from campus locations to the facility located in York, ME. Under the second option, Mr. Fox staff would pick up campus food waste once or twice weekly. Both options require the purchase of 32-gallon bins in which to collect the food waste, which can be purchased from Mr. Fox Composting or from another vendor. Note: Composting Compostable-ware For Options 1 and 2: To address the issue of compostable serviceware, the University could invest in a grinder to process these materials, although evidence regarding the successful breakdown of these products—even in shredded form—is mixed. Although very little technology exists for grinding compostable serviceware in particular, some composting operations have considered or tried—with limited success—generic woodchippers or tub grinders to handle this waste stream (J. Maxwell, personal communication, June 15, 2017). Martin’s Farm in Greenfield, MA, however, accepts and successfully grinds compostable serviceware before incorporating this material into the facility’s windrow composting system. Farm operators use a Bandit Beast® Horizontal Grinder to grind 15 tons of incoming material, including compostable-ware, each day. The grinder also shreds pizza boxes and animal bones that require size reduction before composting. Grinding this material to a consistent size increases the efficiency and effectiveness of the composting process, and any large bioplastic particles remaining at the end of the process are filtered out through a screener (A. Donovan, personal communication, July 24, 2017).
Although investing in a Beast® Horizontal Grinder is illogical given the much smaller size of UNH’s organic waste stream, purchasing a smaller alternative grinder could be very beneficial to the University’s composting process. Options include the Bandit Intimidator 12XP Towable Drum Style Hand-Fed Chipper or the Salsco 600 Series Gravity-Fed, Engine-Driven Chipper. Additionally, if UNH plans to sell the finished compost, a screener would need to be purchased to filter out larger pieces of compostable-ware. Screeners can cost up to $60,000, however, so due to this expense, the University could consider investing in these products when new, more affordable technologies appear on the market (M. Smith, personal communication, July 31, 2017). For Option 3: ASP systems can successfully break down compostable-ware, although success depends on product brand, the polymers the items contain, and the internal temperature of the compost pile. Because of mixed evidence, many composting operators do not accept compostable-ware in their ASP systems. The owners of the commercial-scale Green Mountain Compost ASP system in Vermont do accept compostable-ware, however, after a study demonstrated that certified-compostable utensils break down almost completely after 173 days in a 90 to 150°F ASP environment (Clark, 2014). Grinding or shredding the compostable-ware before incorporating this material into the pile would increase the efficiency and effectiveness of item degradation but, as noted above, UNH would also need to purchase a screener for filtering out larger pieces of compostable-ware that haven’t decomposed sufficiently if it plans to sell finished compost (ILSR, 2014). For Option 4: In a 2015 report, European Bioplastics wrote, “So far, little information on anaerobic biodegradation of bioplastics is known, and further research is welcome to assess the potential biogas (energy) production due to bioplastics” (p. 7). Degradation of these products (and other compostable-ware) is possible in many anaerobic digestion systems provided the products are first ground, shredded, or otherwise processed, but some products that require fungi (which are absent in an anaerobic environment) for decomposition are not compatible with these systems (European Bioplastics, 2015). UC Davis’ wet fermentation, thermophilic AD does not accept compostable-ware or bioplastics due to the system’s “sensitivity;” operators could grind and feed these items to the digester, but utilities director Mike Fan doubts the true biodegradability of these products in an AD system (personal communication, July 18, 2017). Because further research and evidence is necessary to determine the degree to which compostable-ware is suitable for anaerobic systems, UNH should search for alternative means of handling compostable-ware. Potential temporary solution: While pursuing one of the composting options above, the University should consider contracting composting services for compostable serviceware. Mr. Fox Composting collects and successfully composts compostable-ware (and other organic waste). Because the Dairy Bar is the campus’s primary generator of compostable-ware waste—and because all Dairy Bar food waste is currently landfilled—Mr. Fox could provide a significant and valuable service by collecting both food waste and compostable-ware from this location until UNH determines how to successfully incorporate compostable-ware into its own composting system. Because organic waste generated from the Dairy Bar is not currently
weighed, it is difficult to estimate the cost of contracting with Mr. Fox Composting, although Bedard may be able to provide a very rough quote. Furthermore, incorporating bioplastics into UNH’s composting system would make finished compost unsuitable for application to certified organic fields. Although compost containing other non-synthetic compostable-ware can legally be used on organic fields under current standards, compost formed with bioplastics cannot, due to the various “prohibited” materials and polymers contained in these items (Mirenda, 2015). Due to this restriction, UNH cannot incorporate bioplastics into its composting system if the finished compost is destined for application on organic fields. Additional alternatives: In addition to the five options listed above, two other alternatives exist, although their respective details have not been fully fleshed out. First, UNH could incorporate composting into the campus waste management contract, which is set to be renegotiated by the end of this fiscal year and will last a minimum of five years. In its request for bids, UNH can require the waste management service provider to collect and haul compost in addition to recycling and landfill waste. Clark University included similar stipulations in its renegotiated contract with Waste Management. The University also negotiated down the tipping fees for compost compactors (so that compost tipping fees fell below landfill tipping fees) and required that Waste Management routinely clean and power wash the composting compactor at no additional cost to the University (J. Isler, personal communication, July 14, 2017). As organic waste handling becomes more popular and lucrative, waste management service providers are apt to accept contracts that incorporate composting into traditional service structures. Casella, one of the two prominent local waste management companies capable of handling UNH’s large waste quantity, already offers compost collection services. Mike Durkin of the UNH Procurement Services department proposed a second composting option based on an exchange of land for composting services. UNH could provide, free of charge, an unused tract of UNH-owned land to a composting entrepreneur (i.e., someone interested in building his/her organic waste business). In return for the free use of land, the composter would be tasked with collecting and hauling campus waste to this site and managing the composting process. S/he would also be permitted to accept organic waste from other businesses and entities if desired and to sell the finished compost if proper permitting is acquired. The tractor and windrow turner currently used at Kingman Farm could be leased to the entrepreneur if they serve no other immediate purpose to UNH. Drs. John Aber and Matt Smith have significant experience and knowledge about composting systems and the alternatives that would best suit UNH; they also possess detailed blueprints for potential windrow and ASP system operations. Before selecting a food waste management strategy, decision makers should convene with Aber and Smith to discuss these alternatives.
