Hi Thurman,
A recurring topic that’s come up in our zero waste conversations has been the desire to track and display more metrics under the zero waste theme on the iCAP Portal. Grind2Energy data was one metric that was brainstormed, as it relates closely to our Zero Waste Objective 5.5, “Plan for organic waste.” Since Dining already tracks that data, it would be easy for us to get it up on the portal. Would this be something that you’d be in favor of us doing? If so, any input on how the data is displayed (by month, or annually)?
Thank you,
Daphne
Hi Daphne,
Fate has it that I will be seeing the Grind2Energy people tomorrow at the National Restaurant Association show in Chicago. I would like to see if this is something that can by automatically updated from our system. They may have some functionality for this and if not, it may be some thing they could create and would be a selling point for them. I will find out the possibilities. I would rather that this be auotmatic so that the data is always current and nobody can "drop the ball" along the way.

There are a few examples of clean thermal energy in use on campus at this time. These include:
We could expand these types of energy systems...
Another option for clean thermal energy is biogas, which UIUC contributes to locally through the Grind2Energy system, which takes food waste from the dining halls to the Urbana-Champaign Sanitary District (UCSD). UCSD puts it through their anaerobic digester which captures the methane (a very strong greenhouse gas). Currently, that captured methane is used to run an electrical generator, which provides power to the UCSD facility. An alternative would be to upgrade the methane to pipeline quality and use the biogas a Abbott Power Plant on campus. This is an expensive option that would require a lot of coordination and funding.
Another strong option is a micronuclear reactor, which is being studies by the Grainger College of Engineering faculty and researchers. This system could be integrated with the existing steam distribution system and provide ghg-free energy to campus.
On January 30th, the Zero Waste iCAP team met to discuss final thoughts on the finished tailgate recycling recommendation, the feasibility of a large scale composting program on campus, and current work with the Student Athlete Advisory Committee (SAAC).
Meeting minutes are attached.

Ehab Kamarah and Madhu Khanna approved $135,000 of funding from the Carbon Credit Sales Fund for the Grind2Energy system.
"This project will install the Grind2Energy system for food waste at the Lincoln Avenue
Dining Hall on campus... Housing has successfully installed the Grind2Enery system as a sustainable solution for dining hall pre-consumer and post-consumer food waste in four of the five dining halls. This funding would allow them to complete the final installation before the student body returns in fall 2022." -Morgan White (12/14/2021)
An email of approval is attached below.
The following message was sent to Morgan White to share with Carbon Credit Fund Administrators by Thurman Etchison, the Assistant Director of Dining - Facilities and Equipment, on November 18, 2021. The email & attachments contain important information regarding the potential installation of a Grind2Energy system at LAR:
Carbon Credit Fund Administrators,
Housing Dining Services is seeking funds to add a Grind 2 Energy system to our Lincoln Avenue Dining Hall. Grind 2 Energy is a system that allows us to put our food waste into a pumpable slurry so that it may be taken to an anerobic digester at the Urbana-Champaign Sanitary District. These systems replace the aerobic digesters we previously had in our dining units. The aerobic digesters had issues with the effluent not meeting EPA standards.
This system would be our fifth and likely final system as we would have one at every residential dining location. These are operational at Ikenberry, PAR, FAR and ISR. Currently, University Housing does not have resources to fund this project due to the impact of COVID on our budget. We would reach out to the Student Sustainability Committee for funding but for us to do the infrastructure work and have the unit installed prior to the next school year, we need to start before the next round of submissions.
The use of Grind 2 Energy has been a very successful program for us. It meets our needs, keeps us in compliance with regulatory bodies, is comparable in costs to other methods of disposal. It is very sustainable in terms of the environment. To date, we have diverted 289 tons of food waste even though there was limited use until this school year.
The amount we are requesting is $133,538.00. A simple breakdown of our expected costs is below. As our tradespeople have installed the 4 previous units, we believe this number to be very accurate. Our last unit came in within $1000 of our estimate.
LAR Grind 2 Energy – Preliminary Budget Cost
I would like to add that these units are highly visible on campus and it is our intention to start highlighting the metrics in our dining units via electronic messaging. This may include digital displays, The Housing Insider and social media platforms. There is also great deal of interest in biogas impact from these units. I have met with 2 groups of students from the CEE 190 class about these units in the past month.
In short, this program reduces carbon emissions, produces fertilizer and creates energy. The systems are highly reliable and have had almost no issues to date. Please see the attachments for additional info.
Thank you for your consideration,

To combat the issue of food waste, U of I Housing collaborated with F&S Utilities & Energy Services, Operations, Maintenance & Alterations, and environmental compliance. The committee researched various food waste options, including composting, pulpers, and grinder systems used for anaerobic digestion -- including Grind2Energy systems.
These operate similarly to an industrial garbage disposal. However, it uses significantly less water than the digester system, up to 90-95 percent less. Additionally, it does not send the waste directly to the sanitary sewer. The food waste is pumped into a 5000-6000 gallon tank located on the outside of the building it serves. A tanker truck empties the waste and takes it to the local sanitary district. The industrial-strength waste is processed in an anaerobic digester, where it undergoes treatment without oxygen. The methane produced is collected and used to generate electricity at the treatment plant.

Grind2Energy: Turning Campus Food Waste into Fuel
The 49,000 students educated at the University of Illinois can generate a lot of food waste. Most of it winds up in a landfill. But for students with a dining hall plan, food waste is ultimately turned into energy, helping the campus reduce its carbon footprint.
With the "Grind2Energy" system, food scraps are ground down and ultimately run through an anaerobic digester at the Urbana-Champaign Sanitary District, producing methane that is used for fuel to power the plant. The system was installed at Florida Avenue Residence Halls last fall, and others are in the works.
"Hopefully this small piece will be part of a bigger system down the road," said Thurman Etchison, Assistant Director of Housing Dining Services for Equipment and Facilities.
In 2018, all 6 Enviropures were decommissioned. At the beginning of the 2019-2020 school year, Dining began the installation of the first Grind2Energy system. See the Grind2Energy project page for more details.
On November 12, 2018, Sarthak Prasad from Illinois Sustainable Technology Center (ISTC) presented a Food Waste Management study to compare the current mode of food waste management (EnviroPure) with 7 other food waste management equipment.
He recommended the Housing at UofI switched from the EnviroPure systems to InSinkerator's Grind2Energy systems as food waste processing system, before sending the processed food waste (in slurry form) to the Urbana-Champaign Sanitary District (UCSD) in Urbana, IL. UCSD's Wastewater Treatment Plant (WWTP) has existing anaerobic digesters that can convert food waste into valuable biogas for electricity generation.
