Discussed progress with biogas presentation, contacts for additional information for presentation, steps toward drafting a biogas recommendation (i.e. multi-SWATeam meeting), timeline for presentation and recommendation completion. Also discussed the potential for the iWG to put forward this recommendation as opposed to SWATeam(s).

Projects Updates for Anaerobic Digester at Beef and Sheep Study
- Associated Project(s):
Discussed inter-SWATeam collaboration on future biogas recommendation, reviewed and edited presentation regarding biogas production and use. Shared data on dining hall food waste to biogas potential and routes to acquire life cycle cost analyses and additional data for biogas presentation (e.g. fertilizer potential of AD digestate).
David and I met on November 20, 2019 for our first meeting following his Biogas on Campus email on November 13th. David received an email from Doug Wolters from the College of ACES, and Doug said that he will discuss this project with his Dean. David had not heard from anyone else.
We discussed how to proceed with this project. I will try to get in touch with Lance Schideman to get his opinion on this subject. I introduced David to the SWATeam Clerk of the Transportation and Zero Waste SWATeam, Julija Sakutyte. I will talk to the Transportation SWATeam about a possible collaboration opportunity with the Energy SWATeam and Zero Waste SWATeam. David will also talk to the Energy SWATeam about this possible collaboration.
I have set up a biweekly meeting with David, and a monthly meeting with Meredith Moore for this project.
Following is an email sent by David Rivera-Kohr regarding Biogas on-campus to several faculty and staff at the U of I.
My name is David Rivera-Kohr and I’m a student member of the Energy SWATeam. I want to propose using biogas for energy on campus. Since burning biogas for energy is effectively carbon neutral, this would bring us closer to our iCAP goal of achieving net zero greenhouse gas emissions by 2050.
Biogas is a huge untapped resource for energy production at the U of I. Rather than utilize the methane from animal manure and carcasses and food waste, we allow much of it to escape into the atmosphere. The Sanitary District currently uses municipal waste, restaurant grease, industrial food processing waste and campus dining hall food waste as feedstocks for its own anaerobic digester to produce biogas which is burned to generate 25-30% of the facility's energy. However, the Sanitary District does not want to dedicate digestion capacity to manure due to the need to accommodate growth of the local area (i.e. anticipated growth of student population). Furthermore, the Sanitary District is not a UIUC facility, therefore its use of biogas does not alleviate campus energy demand or contribute to our net-zero emissions objective.
I have a few ideas for biogas production on campus I would like feedback on:
1. Add a biogas siphoning system to the manure storage tanks at the Beef & Sheep Farm.
2. Conduct a study to determine which UIUC facility produces the most methane from animal waste and construct an anaerobic digester there. The 2014 Anaerobic Digester Feasibility Study indicated the Swine Farms collectively had the highest methane output; Miles Redden told me the Beef & Sheep farm is the highest manure-producing farcilty, though ionophore feeding of beef cattle decreases methane output. It may be worthwhile to determine which single facility has the highest methane output in 2019-2020.
Additionally, there are a few options in consideration for how to best use the biogas:
1. Burn it on-site in existing natural gas furnaces to meet facility heat demands. This could be used in conjunction with the deep direct-use (DDU) geothermal system that is being studied for the ACES Legacy corridor—the brine solution from the DDU system will bring the facility's hot water to ~110 degrees F and the biogas furnace could increase that temperature to 130 degrees. There would likely be a considerable excess of biogas, which could either be burned on-site to generate electricity for distribution to the local grid (which is less efficient than combined heat & power), transported to nearby facilities to burn in their furnaces, or...
2. Upgrade the biogas (all or only the excess from idea #1) to pipeline-quality methane and inject it into the pipeline for use at Abbott Power Plant. There is a supply pipeline that runs through the ACES corridor where this methane could be injected.
3. Use upgraded biogas for compressed natural gas (CNG) to power F&S vehicle fleets.
The 2014 Feasibility Study also discussed constructing a pressurized pipeline to deliver waste from multiple facilities to the site of the anaerobic digester. This may be worthwhile if the biogas is to be used on a larger scale i.e. at Abbott Power Plant or some combination of the previous ideas.
Life-cycle cost analysis of the above options should be studied to determine the most cost-effective and, more importantly, the lowest emissions option. If you can, please let me know which of these options for biogas production and use sound most feasible, or if better ideas come to mind.
Finally, we need the support and expertise of faculty and staff to advance this proposal. If you are interested in backing or contributing to this proposal, or you know someone else who may be, please let me know. Thank you for your time, and I look forward to hearing from you!

Cary Adams met with Morgan White to discuss options for a PSM internship this summer. He is going to complete an update to the plans for campus to consider an anaerobic digester in ACES facilities, specifically for the Dairy Farm relocation that is shown in the Master Plan.
Anaerobic digestion (AD) is one of the most established technologies for processing waste organics. This study investigated the feasibility of installing an Anaerobic Digester to produce renewable energy from available streams of organic waste (feedstock) within the University of Illinois Urbana-Champaign campus. This study assumed that one on-site digester would be installed in the University’s South Farms. The best digester and energy conversion options were explored while considering UIUC’s existing resources and operations, as well as the goals stated in the Illinois Climate Action Plan (iCAP).Attached Files:
