New greenhouse in Minnesota uses bio-diesel from algae, and nutrient waste from aquaculture
July 16, 2012 By Treena Hein
A greenhouse integrating food production, algae production for bio-diesel, and aquaculture has just opened in Minnesota, as part of the Silver Bay Eco-Industrial Business Park. The University of Minnesota is a project partner.
“The bio-diesel generated from algae [is a] renewable energy source for not only the greenhouse, but the entire park,” states the Silver Bay municipal website. The greenhouses will generate produce and fish year around for local consumption by citizens, schools, restaurants, and other sources.
“The purpose of the Eco-Industrial Business Park is to network businesses to work with each other and the Silver Bay Community in order to create and diversify living wage employment by improving resource productivity, eliminating pollution and expanding markets through renewable, sustainable energy development.”
CHP system also part of Park
A keystone of the Park is the development of the Combined Heat and Power plant which will use biomass as its raw material. “The Pellet Facility would be one of the largest main users of both the heat and the power that would be generated from the CHP plant. The Pellet Facility would create pellets for the retail market. Currently we are identifying additional funding resources to help with permitting and design.
Because of the innovation of the Silver Bay Eco-Industrial Business Park, unique opportunities to expand our local educational opportunities exist. We are working with local secondary, post-secondary, and specialized educational organizations to identify specific courses that will help with workforce development training and research and development for the future.
Although our focus is on the top three clusters, the other identified clusters are either existing or are considered ancillary businesses that would be created once the larger clusters become more developed.”
Goals of the Eco-Industrial Park (from the park brochure):
1.Create an Eco-Industrial Business Park that is self sustainable using heat and power generated from renewable energy production systems that are locally owned.
2. Create economic development clusters that network businesses and industries so that one business’ waste is another industry’s feedstock.
3. Create opportunities that utilize existing natural resources within a 50 mile radius of Silver Bay while maintaining the integrity of our Northshore environment.
4. Create living wage jobs.
5. Diversify the employment base while increasing the tax base.
6. Support sustainable forest management and create opportunities to help retain the local logging industry.
7. Create a long-term revenue resource for future economic growth and community development.
Timeline for project
