City Power Case Study

  • Toledo Oregon

Residents of Toledo City Oregon, a small city of 4,000 residents,  are considering the use of SREUS technology to solve their city problems. The city buys power for its customers from regional suppliers. Toledo city provides full utility services. They have costs for drinking water, sewer treatment costs, and landfill costs which are complicated by a full garbage landfill.

They process about 500 thousand gallons of sewer water a day with about 6,000 lbs. of sewage solids. Sewage sludge is currently being dumped on local Indian tribal land because the city landfill is full and the cost for acquiring more land is prohibitively high. This case study suggests that between garbage and sewage sludge they could produce all the power and water the city needs, reducing both maintenance costs and the price of power to their citizens. Reduced power costs and decreased need for landfills could allow money for infrastructure updates. Power production could exceed needs and offer additional revenue by selling back power to the grid. In many cases city municipalities can apply for government money or pass bonds which make installation of this type of equipment possible.

FUEL

One man’s trash is another man’s treasure. Well, in this instance, perhaps your trash could be your treasure… When it comes to producing power and clean water using the SREUS system, there are many fuels that can power it: 

Single layer and multi-layer cardboard can be used.
Typically from food plants, cut-off ends, peelings, seeds, pits, damaged or rotting food, and anything that goes down a garbage disposal can be recycled as SREUS fuel.
Grass clippings, tree trimmings, leaves, old hay, straw, weeds, and invasive plant species are great fuel options.
Paper fiber, newspaper, mail, and adds are all viable fuel options.
Plastic garbage or recycling rejects, polyethylene, polypropylene, milk jugs, plastic bottles, grocery bags, and even baby diapers can act as non-toxic fuel for a SREUS unit.
Yes, even post-flush waste can be used.
Sewer gas is methane that comes off of decomposing sewage water. Captured sewer gas could also be used as fuel.
Sawdust, wood fibers, sticks, twigs, and shredded stumps are great SREUS fuels.
