    Use Clean Thermal Energy
    Solar Thermal at ARC
    Biomass Boiler at the Energy Farm
    Geothermal on Campus
    Grind2Energy

    There are a few examples of clean thermal energy in use on campus at this time. These include:

    • the solar thermal panels on the Activities Rec Center, heating the three swimming pools
    • the biomass boiler at the Energy Farm, heating the two story greenhouse on south Race Street
    • geothermal installations providing heating and cooling at the Fruit Farm Admin Building, the RIPE greenhouse, the Campus Instructional Facility, a few buildings at Allerton Park, the solar decathlon Gable Home at the Energy Farm, and a few rooms in the Hydrosystems Building
    • a wood-fired stove heating some maintenance buildings at Allerton Park

    We could expand these types of energy systems...

    • Additional geothermal installations are being planned for various places around campus, including a geothermal battery system at the Energy Farm.  The other geothermal locations in planning discussions now include the South Campus Center for Interdisciplinary Learning, a future greenhouse for CABBI, and the Doris Christopher Kelley Illinois Extension Building in the Arboretum.
    • The biomass boiler at the Energy Farm was designed with the anticipation of future expansion.
    • Solar thermal is a great option for our area of the planet, but it is not easy to integrate it in our existing energy enterprise.

    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.

    Carbon Credit Purchasing Program with Second Nature

    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

    • LAR Grind 2 Energy System (equipment and labor)…..................................................................... $86,000
      • (Rigging fees)........................................................................................................................... $4,650
    • Concrete Slab Work (existing planter modifications site work & new concrete slab)….................... $23,100
    • New Wall at Table (Demolition, floor work, ceiling work, MEP & new wall)…................................... $19,788
    • TOTAL:                                                                                                                                              $133,538

     

    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,

  5. Article Highlights Conversion of Food Waste Into Energy

    Associated Project(s): 
    Enviropures
    Plan for Organic Waste
    Reduce Foodwaste
    Grind2Energy

    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-horizontal.jpgGrind2Energy: 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.

    Reduce Foodwaste

    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.

    See attached the presentation in PDF form and the detailed cost analysis.
