Abstract: The Earthginuity Composting System is an organic waste composting system. It consists of three steps/components. The first step is using a free-standing cylindrical tube that goes in the kitchen. Organic waste goes into the tube. The second step is the Phase 1 Bin. It is a square-shaped plastic bin that sits on raw earth, and it's about thirty three gallons in volume. It has drainage holes at the bottom and two pegs protruding from the front to serve as “anchors” for dumping. The final component is the two Earth Grids. They are three by three feet, sandbox-like squares with NO bottoms and liquid-tight lids. The lack of a bottom to the Earthgrids allows for sitting on raw earth to attract ground bugs/bacteria. The lids have rain holes. You can open, close, and empty the Earth Grids with a Shepherd's Staff (hooked pole).

Abstract: An hydrolysis stage of an anaerobic digestion (AD) process includes supercritical treatment in a reactor (R1). The treatment may use sub-stoichiometric oxygen so that there is not full oxidation. Effluent from the supercritical treatment may be used to pre-heat the organic matter in-feed to the supercritical treatment. There may be a second supercritical treatment in a second reactor (R2). This may have full stoichiometric oxygen, to oxidise the solids from the first reactor (R1) effluent. Furthermore, it provides heat for pre-heating its own in-feed and also that for the first reactor (R1). The output from the hydrolysis may be only clarified liquid, leading to particularly efficient downstream AD processes. The second supercritical treatment rector may oxidise also fed-back solids from the final stage of the AD.
