Process of treating organic waste
Abstract
Abstract CONVERSION OF ORGANIC WASTE INTO ORGANIC PLANT FOOD IS CARRIED OUT BY SUBJECTING THE WASTE TO HEAT SUFFICIENT TO STERILIZE, DEODORIZE, AND DE-WATER THE WASTE, THE HEAT BEING GENERATED BY THE CHEMICAL REACTION OF MIXTURE PRINCIPALLY OF MAGNESIUM OXIDE AND SULFURIC ACID. ALTHOUGH COMMERCIAL MAGNESIUM OXIDE MAY BE USED, A PREFERABLE SOURCE IS FINELY GROUND OLIVINE, A LESS HIGHLY REFINED AND LESS EXPENSIVE MATERIAL CONTAINING A LARGE PERCENTAGE OF MAGNESIUM OXIDE. OLIVINE IS A MINERAL COMPOSED ESSENTIALLY OF THE OXIDES OF MAGNESIUM AND IRON BUT ALSO CONTAINING ALUMINUM, NICKEL, AND OTHER TRACE ELEMENTS. WHEN THE OLIVINE IS MIXED WITH CONCENTRATED SULFURIC ACID, A PASTE IS FORMED WHICH IS THEN MIXED WITH THE WASTE. THE EXOTHERMIC REACTION WHICH TAKES PLACE PRODUCES A COMPOST-LIKE MATERIAL WHICH IS VALUABLE AS A PLANT FOOD.
