Performance Evaluation of Seven on-farm Digesters in NYS: Part 1
Performance Evaluation of Seven on-farm Digesters in NYS: Part 2
Overview: Conceived, developed, and implemented a methodology to evaluate the performance of five on-farm, manure-based anaerobic digester systems in New York State for Phase I of the project. Subsequently, four of the same digesters and one new digester system was monitored for one year following the Association of State Energy Research and Technology Transfer Institutions (ASERTTI) performance evaluation protocol. At each farm, the performance evaluation of the anaerobic digester system included three main areas: 1) the conversion of biomass to biogas, 2) the conversion of biogas to useful energy, and 3) system economics.
Overview: A feasibility feasibility study was conducted through funding provided by Senator Joseph Griffo of the 47th District in New York State to assess the multiple biomass-related components including: resource assessments, sampling and laboratory analyses (biochemical methane potential and nutrient concentration investigation), methane production estimations and trucking analyses. The scope of work also included biogas to energy conversion quantifications, digester site option investigations, and economic profitability analyses.
NYSERDA Agreement No. 7536: Transferring Technology from NYSERDA Agricultural Innovation Manure Projects - 1/1/2003 to 3/31/2010
Overview: NYSERDA commissioned several waste-to-energy projects in New York State and this project was to analyze and report on the data collected from these project by others, and develop and deliver extension/outreach materials to farmers and their advisors. Most of the case studies, fact sheets and posters on this website were developed under this project.
NYSERDA Agreement No. 9446, Task 2: Evaluation of Anaerobic Digesters Located at Emerling Farm and Sunny Knoll Farm Following the ASERTTI Protocol - 3/1/2007 to 6/30/2011
Overview: Two New York State on-farm dairy manure-based anaerobic digester systems were monitored for one year following the Association of State Energy Research and Technology Transfer Institutions (ASERTTI) performance evaluation protocol. At each farm, the performance evaluation of the anaerobic digester system included three main areas: 1) the conversion of biomass to biogas, 2) the conversion of biogas to useful energy, and 3) system economics.
NYSERDA Agreement No. 7248: Feasibility of Anaerobic Digestion of Sand-Laden Dairy Manure – 12/23/2007 to 3/1/2007
Overview: Sand is widely used for bedding dairy free stalls due to its superior ability to provide a comfortable surface for cows to lie on and also due to is non-organic composition. Anaerobic digestion is a prudent method to treat manure providing requisite odor control for many dairy farms that have long-term manure storages. However, the co-existence of sand bedding and anaerobic digestion on the same farm is not been possible do to challenges in handling sand-laden dairy manure. This project looked at the possibility of separating bedding sand pre- and post-digestion.
NYSERDA Agreement No. 6249C: Treating and Handling Manure on Dairy Farms to Protect the Environment - 4/1/2000 to 7/30/2004
Overview: This project
consisted of developing a conceptual design, designing, constructing, and
operating two innovative dairy manure treatment systems, one a biodrying
system and the second a fixed-film anaerobic digester system. Subsequent to
project commissioning, each was extensively evaluated to determine the
efficacy of treatment manure and also for their economics.
