Full Circle Feed in Syracuse makes healthy, environmentally-sustainable dog treats with unused meats, vegetables, fruits, and breads from restaurant buffets that were prepared but not served. It recently won the grand prize of $10,000 in Green America’s Fall 2016 People & Planet contest in the category of sustainable products and services for pets and animals. “Full Circle Feed will use the funds to set up a more environmentally friendly production process and drying method,” says founder Michael Amadori. “In particular, instead of electricity or natural gas, we plan to use waste heat and biogas generated from anaerobic digestion to bake our dog biscuits. This will greatly reduce our ecological footprint and give us the most sustainable dog treats on the market!”
Full Circle Feed has constructed a pilot-scale digester at the Central New York Biotech Accelerator in Syracuse, a 60,000 square foot LEED Silver-certified facility offering lab space, services, mentorship and education to companies involved in the commercialization of biotech innovation. Wastewater from the company’s manufacturing process will be anaerobically digested in the unit.
Sacramento, California: Dairy Digester Grant Availability Announcement In February
An estimated $45 million in competitive grant funding will be awarded under the California Department of Food and Agriculture’s (CDFA) Dairy Digester Research and Development Program (DDRDP) to provide financial assistance for implementation of dairy digesters and other manure management practices that result in methane greenhouse gas emissions reductions. According to a CDFA tentative timeline, its “Notice of Funding availability” is scheduled to be released in February 2017. CDFA was appropriated $50 million from California’s Greenhouse Gas Reduction Fund, authorized by the Budget Act of 2016, to provide financial assistance for “early and extra methane emissions reductions.” The DDRDP is guided by the California-Federal Dairy Digester Working Group, which is a partnership of state, federal and local agencies with the common goal of identifying and removing barriers to the wide adoption of dairy digester systems in California, according to a news item in the U.S. EPA AgSTAR December newsletter.
Greensburg, Indiana: Kroger Breaks Ground On Second AD System
Kroger Foods, which has an anaerobic digestion (AD) system at its food distribution center in Compton, California, has broken ground on another AD system at its K.B. Specialty Foods processing plant in Greensburg. The project developer is ADI Systems, Inc. which will design, build and commission a 2.7 MG ADI-BVF® reactor system, followed by a 380,000 gallon sequencing batch reactor (ADI-SBR) system for aerobic polishing. The digester reactor is a low-rate anaerobic process that has a lower volumetric loading than high-rate anaerobic processes, thus offers a longer hydraulic retention time and greater biomass inventory, according to ADI.
Biogas will be scrubbed to remove hydrogen sulfide, and then utilized in a genset equipped with dynamic natural gas blending. Power generated will be sent to the plant’s electrical grid, and heat will be supplied to the recycle line of the ADI-BVF® reactor and/or the boiler room. Substantial completion of work is expected sometime in 2017.
Leysin, Switzerland: Standardization Of Biomethane Potential Testing
A workshop held in June 2015 in Leysin with over 40 attendees from 30 laboratories around the world, focused on the possibility for defining a protocol for the determination of the methane potential of a given organic waste. Biomethane potential (BMP) tests of substrates are often used in technical and economic feasibility studies carried out prior to construction of an anaerobic digestion (AD) plant to shed light on such factors as energy income and sizing of the digesters. While several programs exist to standardize BMP tests, such as DIN38414 TL8 (1985), ASTM D5210 (1992), ASTM D5511 (1994), ISO11734 (1995), ISO14853 (1998), and ISO15985 (2004), their formulation of important parameters is often imprecise. This leaves too much freedom for interpretation and ultimately leads to the use of quite different test protocols in different laboratories.
The workshop participants reviewed several interlaboratory testing results and found that the Relative Standard Deviation (RSD) between test duplicates and triplicates varied from 20 to 25 percent, with an average of 14 percent, meaning a substrate with a BMP of 3,000 cfm/ton (cubic feet/ minute) might have an actual BMP of 2,250 to 3,750 cfm/ton. The workshop outcome was a consensus guideline divided into two parts. Part I describes actions and criteria considered compulsory in order to accept and validate a BMP test result; Part II presents recommendations concerning the inoculum, substrate, test setup, and data analysis and reporting in order to obtain test results that can be validated and reproduced. These guidelines were published in the September 2016 issue of Water Science & Technology.
Madison, Wisconsin: Governor Requests AD To Address Water Quality
Gov. Scott Walker has requested the Wisconsin Public Service Commission (PSC), Department of Agriculture, Trade, and Consumer Protection (DATCP), and the Department of Natural Resources (DNR) to coordinate resources and draft a Request for Proposal that aligns digester technology to all sizes of dairy farms in environmentally sensitive areas of Wisconsin. The goal is to alleviate water quality concerns, stated Walker, who made the announcement at the Heritage Farm Site in Kewaunee to address nutrient management and water quality challenges in Kewaunee County. A study released last year found 34 percent of wells tested in the county had unsafe levels of nitrates and bacteria. About 2 percent of tested wells were contaminated with E.coli. The county is home to 16 Concentrated Animal Feeding Operations. The PSC, DATCP, and DNR will make recommendations that propose a tangible private sector response linking the application of digester technology to environmentally sensitive areas of Wisconsin, specifically areas with high concentrations of dairy cattle. A Request for Proposal laying the groundwork for actionable items was scheduled for released in January (see BioCycle.net).
