Background:
Since the dawn of modern dairy farming, two problems have plagued the industry: excess manure, and lack of energy. A dairy of 800 cows can produce something close to 48 tons of manure per day, and without having a farm attached to the dairy, that manure has nowhere to go. That same dairy requires close to $80,000 worth of energy to process milk from those same cows. This invention is a design for a reactor that uses a new method of hydrothermal carbonization (HTC) to make fuel that can be completed in under five minutes, unlike the current conversion method (Anaerobic Digestion) which can take twenty to sixty days and requires a huge footprint.

Technology:

The conversion of biomass to fuel involves treating the wet waste in hot, compressed water. This is accomplished with the invented reactor, which consists of a feed chamber, a high-pressure pump, a reaction chamber, a cooling chamber, and finally, a receiving tank. The reactor size and slurry feed allow for control of reaction time and temperature.

Advantages:

  • This method is on average 10,000 times faster than anaerobic digestion which means a smaller reactor.
  • Wastewater and manure are handled together for flexible operation.
  • Thermochemical operation means robust operation and sterile effluent.
  • This makes it cheap to covert dairy manure to energy, saving dairy farmers money
