A METHOD FOR CONTROLLING THE AEROBIC DECOMPOSITION OF AN ORGANIC MASS BY CONTROLLING THE ADMISSION OF AN OXYGEN CONTAINING GAS TO SAID MASS DURING THE DECOMPOSITION PROCESS CONSISTING OF THE STEPS OF: (A) INJECTING THE OXYGEN CONTAINING GAS INTO THE DECOMPOSING MASS AT A POINT REMOVED FROM A TEMPERATURE SENSING MEANS AND AN EXHAUST GAS ANALYZING MEANS; (B) CONTINUOUSLY ANALYZING, WITH A FIRST CONDITION RESPONSIVE MEANS, THE EXHAUST GAS FROM THE DECOMPOSING MASS AND AUTOMATICALLY CORRELATING THE RESULTS OF SAID GAS ANALYSIS WITH OXYGEN REQUIREMENT LIMITS WITHIN SAID DECOMPOSING MASS; (C) CONTINOUSLY MEASURING, WITH A SECOND CONDITION RESPONSIVE MEANS, THE TEMPERATURE WITHIN THE DECOMPOSING MASS SIMULTANEOUSLY WITH ANALYZING THE EXHAUST GASES, AND ATUOMATICALLY CORRELATING SAID TEMPERATURE MEASUREMENT WITH OXYGEN REQUIREMENT LIMITS WITHIN SAID DECOMPOSING MASS; AND (D) AUTOMATICALLY CONTROLLING THE INJECTION OF THE OXYGEN CONTAINING GAS INTO THE MASS IN RESPONSE TO THE OXYGEN REQUIREMENTS INDICATED BY ONE OF SAID CONDITION RESPONSIVE MEANS AND QUANTITATIVELY ADJUSTED IN RESPONSE TO THE OXYGEN REQUIREMENTS INDICATED BY THE OTHER CONDITION RESPONSIVE MEANS.
