From Solid Waste to Energy: A New Vision For Gainesville-Alachua County

Cross Creek Initiative, Inc CCI, a non-profit corporation Mission: to assist the public and private
sectors in developing new concepts for defining the success of their operations.
Projects: green construction, sustainability planning and leadership, biofuels
Biofuels from MSW Methane Solid biofuels
Composting costs too much? Rapid City SD: “The Cocompost Facility will extend the
life of the landfill for approximately 30+ years and reduce the reliance on land needed to farm biosolids (which will relieve the city of having to buy an additional 1,110 acres of land). Selling the product offsets the cost of operating the facility –the facility uses no taxes to maintain operation.”
Composting costs too much?
Tipping fees of $47 were lowered to $45 after the lower figure proved sufficient to sustain the facility’s budget needs.
Composting costs too much? A current tipping fee of $45/ton (at 135,000 tons/year), which, in
conjunction with revenues from the sale of recyclables and finished compost, supports the city’s entire waste management operation, including capital outlay and debt service. (Projected revenues included $150,000-200,000 from the sale of recyclables, $75,000 from the sale of compost, and a $13.26 monthly average residential garbage fee.)

Landfill vs. compost-biofuel Landfill pays three times to throw away money.

Compost-biofuel makes money on material you are paid to take. Local gov controls own destiny. Waste reduction, carbon-neutral operation is the
responsible, leadership approach.
A new vision for Gainesville-Alachua County? Hedge against uncertainty in landfill costs, flow
control, and operating costs. Be ahead of rising energy prices, climate change
pressures. Shift from a solid waste mindset to a green
energy mindset. Keep talking, bring community, staff, expertise
together to explore emerging concepts, vision. Become a global leader.
