NOVELTY - A sloping preventing agent is formed by mixing lightweight components, bond components and weight components. The lightweight components are formed by performing deodorizing drying of organic waste. The bond components contain tatami waste, wastepaper, wood chip and/or waste plastic. The weight components contain iron powder, carbon powder, coke breeze and/or fly ashes. Then, compression molding of the mixture is performed, to obtain the sloping preventing agent. The sloping preventing agent has specific gravity of 1.7 or more moisture content of 5% or less.    USE - Sloping preventing agent is used for converter for copper and steel.    ADVANTAGE - The sloping preventing agent is manufactured efficiently and economically.    DETAILED DESCRIPTION - A sloping preventing agent is formed by mixing lightweight components, bond components and weight components. The lightweight components are formed by performing deodorizing drying of organic waste. The bond components contain tatami waste, wastepaper, wood chip and/or waste plastic. The weight components contain iron powder, carbon powder, coke breeze and/or fly ashes. Then, compression molding of the mixture is performed, to obtain the sloping preventing agent. The sloping preventing agent has specific gravity of 1.7 or more moisture content of 5% or less. The organic waste contains surplus sludge, agricultural waste, fisheries waste material, agriculture-fisheries processed industrial waste material and food-stuff-industrial waste material. Soil microbes which inhabit sea, mountain and land are used for manufacturing sloping preventing agent. Soil microbes which inhabit mugwort, wild grass, medicinal herb, grass of beach, bamboo grass, ground of bamboo grove, ground of forest, fish, seaweed, fruit, pineapple, apple, orange, loquat and grapes, and used for rice bran and sawdust are used for manufacturing sloping preventing agent. The soil microbe contains enzyme selected from alcohol dehydrogenase, lactate dehydrogenase, glucose-6-phosphoric-acid dehydrogenase, aldehyde dehydrogenase, L-aspartate beta -semialdehyde, nicotinamide adenine dinucleotide phosphate oxide reductase, glutamic acid dehydrogenase, aspartic acid semialdehyde dehydrogenase, methylenetetrahydrofolate reductase cytochrome-C, reactase, glutathione dehydrogenase, trehalose phosphoric acid synthase, poly phosphate kinase, ethanolamine-phosphate cytidylyltransferase, trehalose phosphate, metal thio phospho glycerate phosphatase, inulase, beta -mannosidase, uridine nucleosidase, cytosine deaminase, methylcysteine synthetase, aspartic acid synthetase, succinic-acid dehydrogenase, aconitine acid hydrogenase, fumarate hydrogenase, malate dehydrogenase, citric acid synthetase, isocitric acid dehydrogenase, LSNADP oxidactase, monoamine oxidactase, histaminase, pyruvate decarboxylase, ATPase, nucleotide pyro phosphate, end poly phosphatase, adenosine triphosphate (ATP) phospho hydrolase and orotidine-5-phosphoric acid decarboxylase. An INDEPENDENT CLAIM is included for manufacture of sloping preventing agent.
