Best Practice Actions [See action tools, guidance, city reports]
A biomass combined heat and power system in the Silver Bay, MN Eco-Industrial Park is estimated to increase fuel efficiency in utility-sized coal-fired electric power plants from about 37% to about 75%. In using wood, net CO2 emissions are zero, displacing approximately 150,000 tons per year of CO2. A 2500-kilowatt pellet plant power and district heating system, firing about 10 tons per hour of biomass, is estimated to create 15 permanent pellet plant jobs and 6 logging jobs. Estimated savings from the district heating is $200,000 when compared to using natural gas.
Set within the Eco-Industrial Park is a Biofuel and Food Greenhouse Facility - Victus Farms -- that produces organic food and renewable fuel. The main inputs are fish feed, electricity, heat, and water, which are derived from locally-produced algae and biomass, and readily-available wind and rain. The main outputs are fish (about 12,000 pounds of tilapia per year), organic produce (starting with lettuce, basil, cilantro, parsley, sprouts, and mushrooms), and algae (oil extracted for biodiesel and remains fed back to fish).

Optional for category A, B and C cities
Category C cities that choose to implement this best practice are recognized upon completion of at least one action.
Category A and B cities that choose to implement this best practice are recognized upon completion of at least action 2, 3 or 4.
Fostering communication and networking among businesses, and clustering businesses, can optimize resource use and reduce economic and environmental business costs. Beginning with the observation that in nature, every waste is used by some other organism within an ecosystem, restorative development and eco-industrial business development aims to integrate and optimize energy, waste, water, food and transport systems such that they interface more benignly with the local natural ecosystem. Eco-industrial principles encompass a range of approaches a city can promote, ideally working with a local business association, and include:
connection to state Policy
While not State of MN policy, of note is a major University of Minnesota research network launched in 2015 to develop integrated urban infrastructure solutions for environmentally sustainable, healthy and livable cities. The Network's mission is to advance environmental sustainability, health, and livability in diverse cities across the world through infrastructure innovations in energy, water, transportation, green infrastructure, and food systems, linked with social, behavioral, and policy change.
