A durable watertight plastic bin in the solar chamber has enough capacity for 4-6 persons in daily use. Easy access to the compost bin simplifies emptying at 6-12 month intervals, depending on loading. Built on a 4'X8' platform and weighing 300 pounds, the completed S.C.A.T. can be transported by pickup truck, trailer, or barge. Alternatively, the use of screw fasteners allows prefabrication of panels for simple onsite assembly. Passive solar heat enhances evaporation to dewater the compost pile.
Ventilation is provided by convection currents through a storm-proof ventilator.
By-products are heat, water vapor and carbon dioxide. Screened vents exclude insects. Pathogens are removed by heat and aging. Construction materials are durable and easily cleaned. Modular design simplifies damage repair.
