Non Technical Summary
The historical land balance model between the acreage needed to grow the feed to support a dairy cow and the area required to safely utilize the nutrients in the manure produced by a cow is no longer valid for many American dairies. Production specializations, advances in crop/animal science and the expansion of dairy herds, has created critical situations in which excess nutrients from surplus manure has contributed to air and water quality problems. The only viable solution is to have raw manure converted into a value-added product that allows it to be transported out of agriculturally intensive watersheds. These manure management costs have to be recouped from sales of the value added product (RTS proposes vermicompost) thus allowing excess nutrients from dairy operations to be handled in an economically and environmentally sustainable manor. Vermicomposting of animal manures is an emerging waste management technology with many technical and potential economic benefits over traditional composting systems. This project will evaluate the true viability of integrating a large-scale vermicomposting facility with a working 1,000 head dairy operation to produce a consistent quality vermicompost product year round in a temperate humid climate. A state of the art vermicomposting facility will be a win-win-win scenario for the animal producer (dairy), vermicomposting facility owner, and the consumers of the earthworm soil conditioner/fertilizer products.

Goals / Objectives
A true agricultural-production scale, hybrid-earthworm composting system (10 tons per day), will be constructed and fully commissioned to evaluate the technical, operational, and economic feasibility of vermicomposting as a dairy waste management alternative for the temperate regions of the United States. Continuous operating data, finished vermicompost product evaluation, weekly system production, and related economical parameters of a working vermicomposting facility will be collected, in order to determine the commercial potential for integrating large-scale vermicomposting systems into existing dairy operations. RT Solutions LLC (RTS) will perform this evaluation through the collection and analysis of real-time data from the Company's new, state-of-the-art vermicomposting facility recently integrated into a 1,000 head dairy operation located in the Finger Lakes Region of New York State. Specific technical objectives for the project include: 1. Evaluation of RTS's newly installed dairy manure separation system and integration into the Coyne Family Dairy operation. 2. Develop operational methods to link thermophillic composting parameters (physical, chemical, and biological) to earthworm dynamics inside the vermicomposting digester. RTS's hybrid system requires proper composting to maintain high worm population and overall system productivity. An operational model will be developed (dynamic balance) that has to account for the varying properties of initial feedstocks (separated dairy solids and off-specification dairy feed silage) and seasonal climatic conditions; 3. Facility engineering. Improvements to the processing / vermicomposting phase with an emphasis on economic/labor inputs needed for the physical environmental controls necessary to sustain the high-density worm population. Worm population is key to meeting the required financial targets based on facility product production rates (volume of product to sell). 4. A redesign and fabrication of the flow-through digester feeding systems based upon the physical characteristics of pre-composted materials. 5. Unit cost and operational evaluation of increased production and related economic data from installing a fourth, flow-through digester; 6. Develop a product marketing program thru determining the qualitative and quantitative results from a dedicated market study and sales effort to assess the actual market size and per ton value for various finished vermicompost products; 7. Obtaining U.S. Compost Council's Seal of Testing Approval (STA) for product and becoming organically certified through the Organics Materials Review Institute (OMRI) through extensive material sampling and analysis will be required to obtain both testing approval and organic certification.
Project Methods
In order to satisfy the above technical objectives, research will be conducted by RTS employees, and select consultants at RTS new and fully functional integrated dairy / vermicomposting pilot facility located in Avon, New York. A significant level of testing, data collection and operational experiments will be conducted at each point of the process throughout the vermicomposting pilot facility. It is also essential that the research approach (all operational experiments, testing, and data collection) include the analysis of seasonal effects and climatic changes, experienced in the Northeast, have on the processing and environmental controls of the facility. This will be a key point in evaluating the true analysis of the systems viability with respect to geography and climate.

Outputs
As proposed by RT Solutions, LLC (RTS), the anticipated results of the Phase II SBIR project included: a detailed technical and scientific evaluation on the feasibility of a hybrid vermicomposting operation as a viable manure management technology for dairies in temperate regions of the United States. RTS is utilizing their fully operational pilot scale vermicomposting facility (as completed under the Phase I portion of the project) in order to accomplish this objective. As outlined in the Phase II proposal, RTS identified the following five tasks as the necessary technical objectives required to assist them in determining the feasibility of vermicomposting as a manure management technology: 1. Evaluation of an Integrated Manure Separation System and Commercial Vermicomposting System Into an Existing Dairy; 2. Evaluation of the Composting/Conditioning Phase; 3. Evaluation of the Vermicomposting/Processing Phase; 4. Market Study and Development of Marketing Programs; and 5. Vermicomposting Material Analysis and Organic Certification. Having completed the commissioning of one of the largest vermicomposting facilities in the United States, RTS continues to monitor real time operational and production data collected under varying working and seasonal conditions. To-date, much effort has been devoted to the monitoring of actual material processing rates (total incoming raw feedstock materials related to total quantity of finished vermicompost products produced) with respect to the effects of seasonal changes as well as variability of material properties. This data has allowed RTS to develop a model to determine accurate material processing rates as well as determine true measurements of mass balance and nutrient balance from the beginning to the end of the process. RTS can now use the model to establish true long-term, large-scale system processing rates (with ability to pro-rate to larger facilities for increased economy of scales). In conjunction with the above, economic spreadsheets have been developed to assist in determining an overall unit cost on a per-ton basis (received and finished). Collected data includes actual initial capital costs, actual monthly operational costs, actual monthly finished product production rates, and sales projections. Progress has also been made in analyzing, engineering and implementing the physical environmental controls necessary to maximize a sustaining and self regulating worm population. In response to this, RTS has engineered and built the following; an automated misting system for each worm digester, a digester covering system to assist in regulating suitable moisture and temperature conditions, active automated aeration systems for each worm digester, and on-site design changes to the vermicomposting feeder system. With regards to product certification, RTS Worm Power vermicompost products have been approved for use in organic production by the Organic Materials Review Institute (OMRI). From a marketing standpoint, RTS is currently developing a company/product marketing program for target marketing sectors.

Impacts
Federal nutrient management regulations have recently been enacted that will greatly alter current manure management practices for a large segment of animal agriculture. One result of these regulations is that many mid- to large-sized animal operations will be forced to undergo significant changes in the methods and costs associated with manure handling. In order to offset these additional manure processing and transportation costs (thus allowing excess nutrients from dairy operations to be moved out of agriculturally intensive watersheds) animal producers are searching for a technology that will allow them to process their excess manure/nutrients into an alternative value-added product. To produce this value-added product RTS proposes a hybrid of traditional composting and an innovative vermicomposting process. Vermicomposting/Composting transforms the undesirable physical characteristics of raw manure into a value-added consumer friendly product that has a value capable of offsetting nutrient transport costs. RT Solution's (RTS) proposes an innovative process-controlled technology, known as vermicomposting that employs earthworms to accelerate and improve upon the traditional composting process. The findings of the project will demonstrate that a state of the art vermicomposting facility can be a win-win-win scenario for the animal producer (dairy), small-business vermicomposting facility (owner), and the consumers of the value-added organic earthworm soil conditioner/fertilizer products.
