Abstract
919,955. Fertilizers. BINNS, J. Nov. 1, 1961, No. 39067/61. Class 111. A process for making compost from domestic refuse comprises wetting the waste, partially fermenting it by static exposure to air, and after removing metals, grinding and screening, completing fermentation under controlled temperatures and moisture conditions. Prior to fermentation, the wetted waste, which may be supplemented by sewage sludge, may be reduced in size by suitable milling. In a preferred form of the invention, Fig. 1, refuse is placed in a pot 4, sprayed with water from an overhead spray (not shown) and transferred to fermentation cells 6 which may contain voidforming elements to aid aeration. After about 3 days, when the temperature rises to about 150‹F., compressed air is blown on to maintain this temperature for a further 3 days. The partially fermented mass is then transferred to hoppers 12 whence the material is conveyed by belts 13 past magnetic separators 14 and 15 and non-ferrous metal extractors 16, to rotating screen 17. Larger sized material e.g. # in. mesh or more, is conveyed to hammer mills 19, below the outlets of which are vibrating screens 20, from which oversized material is passed back for regrinding. The fine-ground material is then carried by bucket conveyer (not shown) to to the top of fermentation cells 22 to which air and water may be admitted as required to maintain the temperature at 150‹F. The quality .of the material may be enhanced by addition, either before or during fermentation, of aqueous solutions of nitrogen-containing compounds. The waste, before fermentation, suitably contains 45% to 65% by weight of water.
