• Forty-seven acre site with 4,670 feet of fence.
• Closest residence 1,600 feet from the site.
• Craig Coker, Coker Composting and Consulting, provided valuable assistance with design, equipment decisions, operational time budgets, and recipe formulations.
• After much deliberation and many demonstrations, Komptech equipment was selected. Windrows turned once every three days.
• Process to Further Reduce Pathogens (PFRP) is considered achieved once temperatures meet or exceed 131 degrees Fahrenheit for 14 consecutive days within the windrows.
• When necessary, the windrow turner can apply water to the windrows.

• The SMSC Organics Recycling Facility is rooted in tribal cultural values.
• Historically the Dakota did not throw anything away when it came to harvesting animals for meat. Everything was used (meat, hide, bones, tendons, organs, etc), and anything left over was repurposed.
• Part of Shakopee Mdewakanton Sioux Community environmental commitment to land stewardship.
• Part of overall waste reduction program which includes recycling efforts: office paper, boxes, newspapers, cans, bottles, electronics, plastics, and more.
• SMSC uses several tons of compost a year on various sites on the reservation including Mdewakanton Wozupi (certified organic garden), landscaping, and prairie restoration areas.
• Uses best practices in the design and management of the facility in keeping with tribal values.

• Composting is a biological process in which microorganisms convert organic materials into a soil amendment called compost. 
• It is the same process that occurs naturally in forests and other natural communities. 
• Compost is a soil conditioner that adds organic matter, improves soil structure, reduces the need for synthetic fertilizers, adds water-holding capacity to soils, and reduces potential erosion.
• Commercial scale composting, at sites like the SMSC Organics Recycling Facility, simply manage the conditions by creating a favorable climate for microorganisms that speed up the composting process.
• In commercial-scale composting, temperatures reach 140-160 degrees for weeks at a time, and this process takes approximately 12 weeks to kill pathogens and weed seeds. 
• Raw materials go into a compost pile where they are exposed to water, heat, and carbon dioxide.
  • Organic matter (including carbon, chemical energy, protein, and nitrogen)
  • Minerals (including nitrogen and other nutrients)
  • Water
  • Microorganisms
• The result is finished compost which is organic matter (including carbon, chemical energy, nitrogen, protein, and humus) minerals, water, and microorganisms.
• Humus refers to any organic matter that has reached a point of stability, where it will break down no further.
• More appropriate than landfilling organic debris because composting occurs with oxygen and produces carbon dioxide whereas landfilling occurs without oxygen and generates methane is 23 times more powerful as a greenhouse gas compared to carbon dioxide.  Thus composting significantly reduces greenhouse gas emissions.

• Customers use the all weather road to enter the site at the Scale House where their materials are inspected and weighed.
• They are directed to a Tipping Area to dump their materials.
• Tipping Areas are identified by numbers.
• Tipping is completed on an impervious pad.
• Customers exiting the site are weighed again, and a tipping fee is paid based on weight dumped.
• Materials, also known as feedstocks, are ground and shredded using a KompTech Crambo 5000 Slow Speed Grinder.
• Feedstocks are mixed with other materials using a recipe to achieve optimal carbon-nitrogen-moisture balance and formed into windrows.
• For the first 15 days, the windrow is maintained on impervious pad as part of the Process to Further Reduce Pathogens (PFRP).
• Windows routinely achieve temperatures of 130-160 degrees Fahrenheit for weeks at a time.
• Microbes within composting materials generate the heat in composting. 
• Each windrow is turned about 30 times over a 12-week period using a KompTech Top Turn X6.
• Finished compost is screened to 3/8 inch using a KompTech Multistar L3, tested, and available for sale.

Feedstocks

• Animal manure
• Compostable plastics
• Any paper products such as soiled napkins, towels, carry out boxes, milk containers

• Brush and branches
• Grass
• Leaves
• Logs and stumps
• Clean wood (chips, sawdust, lumber)

Receiving Waste From

• Residential
• Commercial
• Institutional (e.g., schools/colleges, hospitals, prisons)
• Industrial (e.g., food processors)
• Agriculture

Description

• All transactions are done by weight.
• Food waste loads are priced by several factors including level of contaminates, processing difficulty, odor, and beneficial feedstock.
• Staff regularly collect samples of incoming material for analysis by an outside laboratory.
• All incoming materials are tipped into concrete bunkers on an asphalt surface.
• It is then processed and kept on an asphalt pad using a recipe mixture until all Minnesota Pollution Control Agency standards are met or exceeded.
• Then they are moved to the windrowing area and fully composted.
• The process takes approximately twelve weeks.
• Final products are screened to a 3/8ths of an inch size.
• A variety of organic blends are available for uses such as gardening, rain gardens, soil correction, and roadway projects.
• Composted manure blends are available for use on organic gardens.
• Compost is not currently packaged for resale but is available in bulk.

• Rocks, painted or treated wood, metals, any plastics, trash, ashes, pet and human wastes, hazardous wastes, infectious wastes, medical wastes, or any other non-organic materials are unacceptable.
• Every load is inspected on the tipping floor to insure that all materials are acceptable.
• Unacceptable materials are the customer’s responsibility to collect and remove.
• If necessary, customers will be charged a $100 fee to reload unacceptable materials back into their vehicle.
• Unacceptable material also includes chemically-treated organic waste such as herbicide-treated lawn clippings when collection of clippings is inconsistent with the product label.
• Brush and leaves from counties infested with the Emerald Ash Borer (such as Hennepin County) are unacceptable unless they are ground very finely to prevent the spread of this invasive species.
• SMSC will randomly test incoming materials for trace chemical content.
• SMSC will work with the hauler on a case-by-case basis in the event of a positive test; consequences could include future load rejection.

• Less greenhouse gas emissions. When organic materials decompose in conditions that lack oxygen, methane gas (CH4) is an output, and methane is 23 times more powerful as a greenhouse gas compared with carbon dioxide.
• Reduction of volume by at least half.
• Pathogen and weed seeds are eliminated due to prolonged high temperatures.
• Produces compost to amend tired, eroded soils.
• Some pure, organic wastes with pH levels that are too high for some uses can be composted at the SMSC Organics Recycling Facility. Example: remnants from pickle production.
• Mud from agricultural products can be dried and processed into a black dirt product. Example: from potato factory.

• September 6, 2011, Dick’s Sanitation delivered first load ever from the Prior Lake Savage School System.
• All Prior Lake Savage Schools recycle paper, plastic, and aluminum as in past years but in school year 2011-2012 they added organics to their recycling efforts.
• Recycling organics includes not only food scraps, coffee grounds, lunch trays, and milk cartons, but it extends beyond the lunch room to items like facial tissue, paper towels, pizza boxes, brown bags, pencil shavings, untreated wood, and cloth scraps.
• With this addition, the school system hopes to divert at least 80 percent of their trash from landfills.
• Adding organics to the district’s recycling efforts fits with the district’s mission to be responsible stewards of finances and natural resources.
• Diverting organics to a composting facility will eventually reduce school costs by about two-thirds versus sending that same material to the landfill.
• Glendale Elementary typically had seven bags of lunch trash each day before the organics recycling program began. With only a couple of days of practice, the students at Glendale demonstrated the success of the program by producing only half-a-bag of trash from lunch waste. The rest of the lunch waste was diverted to recycling containers – a pretty impressive feat considering that half-a-bag of trash represented about 600 students.
• Historically Prior Lake High School students and staff recycled half of their school’s waste. Now with the new organics recycling program they are able to further reduce waste.
• Organics recycling for the schools would not be economically feasible without the partnerships with the Shakopee Mdewakanton Sioux Community and Dick’s Sanitation.
• All organic material is hauled to the Organics Recycling Facility on SMSC trust land in Prior Lake.

From September 6, 2011, through January 1, 2012, the following tonnage was processed from our neighboring cities at no charge, saving them a total of $8,427.

• Compost from the Organics Recycling Facility was used to make substrate for the dance area at the SMSC Pow Wow Grounds when it was reconstructed in the fall of 2011. Northwest Asphalt, the contractor on the project, liked it so much that they’ve committed to use it for various projects.
• Compost is suitable for rain gardens.
• Materials unsuitable for hog feeding operations such as coffee grounds and grease can go to composting.
• Pizza boxes cannot be recycled but they can be composted at the SMSC ORF.
• Cardboard boxes from meat for restaurants cannot be recycled because they have wax on them and have been exposed to food so they have to be landfilled. However, they can be composted at the ORF.
• Recipe of roughly three parts brown to one part greens.
• Browns provide carbons, such as straw, leaves, wood, pizza boxes.
• Greens provide nitrogen such as food and green grass.
• Microbes show up naturally because they are ubiquitous in the environment.
• Bulk density fluffs it up to allow space for air; microbes need air to breathe, water, and food.
• Byproduct of microbes is heat, which kills weed seeds and pathogens when sustained over time.
• We turn the windrows and keep moisture and air levels adequate for the microbes to fulfill their function of breaking down the feedstocks into compost.
• Windrows are also known as “piles” or simply “rows.”
• The temperature indicates that the microbes have what they need and are doing their job breaking down the feedstocks into compost.
• Windrows are 20 feet wide by 10 feet tall.
• The windrow turner works like a snowblower as it turns and fluffs the materials.
• Optimal moisture content is 65%.
