Best Practice Action 2

Document that at least one business/building uses waste heat or water discharge from another business or conducts materials exchange activities with another organization.

  • The Minnesota Materials Exchange is a free service that links organizations that have reusable goods they no longer need to those who can use them, at no or low cost. This business reuse network helps prevent usable materials from becoming waste and saves users money. 
  • Minaqua Fisheries Co-op (Renville, Minn.) uses heated water from waste water generated by the nearby Southern Minnesota Beet Sugar Cooperative to raise tilapia fish.
  • Eco-Industrial Development: Concepts and Applications (MPCA: 2012) includes a several slides summarizing resource cascading, by-product synergies, by-product exchanges, and eco-industrial networking.
  • See also GreenStep action 25.2 business assistance resources.
1 star 1 or more organizations registered as users of the MN Materials Exchange; energy/water reuse includes: reuse of non-contact industrial cooling water; reuse of hot water from a laundromat by a nearby greenhouse; use of waste heat from a crematory to heat a nearby recreation center and its pool; using waste heat from a data center. Record projects under best practice action 20.6 where a city wastewater plant sells reclaimed water for non-potable ag-processing, irrigation, cooling or power plant uses, or when the plant co-generates electricity and heat and sells it to businesses.
2 star Describe how the city facilitated at least one such energy/water/materials reuse project.
3 star Report how the city is, on an ongoing basis, helping businesses complete these reuse projects and how many completed projects exist.

The City coordinated efforts for joint powers agreement with the City of Savage and Kramer Quarry to use water that had been pumped from the quarry for dewatering to allow for limestone collection and to re-use the water for municipal drinking water supply.
Reuse projects are possible because of the cities designation of a PUD zoning district that allows the necessary land uses and zoning clearances. Another reuse project is in operation between Waste Management and the City of Burnsville.

Grand Rapids - 2 star
Date action report first entered:
Date of last report update:
Year action initially completed: 2010
Implementation details:
In January 2012 the City of Grand Rapids began using waste hot water from paper production at the Blandin Paper Mill to heat the Grand Rapids Public Library. This was accomplished by construction a new building to house a wide-gap plate heat exchanger which transfers the heat from the waste water to the glycol which circulates through the library. This project has allowed us to reduce our natural gas consumption by nearly 70%. The new building also has a living roof. Half of the new building also will house and education center which will be able to be monitored by anyone with access to the internet. One can view the flow through the heat exchange from an adjoining viewing room. Those viewing the internet will be able to monitor the entire library heating system and actually see how the system works. Internet users will also have access to the k-12 curriculum which will pose a question and answer specific to each grade. Solar and wind project will also be monitored in educational portion of this project.
Outcome measures/metrics/money saved:
70% natural gas reduction. Educational portion of project available for all to view via internet.
