TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The acidic liquid comprises at least one nutrient, where the at least one nutrient is absorbed from the biological waste present in the acidic liquid. The nutrient is at least one of nitrogen, phosphor, potassium, iron, and copper.    TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The filtering unit is one of a gravity settling unit and a centrifuging unit. The thermal cracking unit comprises: a closed chamber for holding the organic slurry; and a heat source for heating the organic slurry held in the closed chamber. Preferred Method: The organic slurry is thermally cracked in a closed chamber, which comprises a venting pipe for releasing the ammonia gas and the flue gas in response to the thermal cracking of the organic slurry.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Method: The mixing of the biological waste with the dilute sulfuric acid comprises stirring the mixture for a predefined duration, where the predefined duration is at least half an hour. The elevated temperature is 900 degrees C. The method further comprises: washing the organic slurry with water in response to the filtering the mixture of the biological waste and the dilute sulfuric acid; passing the ammonia gas through the acidic liquid and at least one of an organic slurry washing liquid, a char and ash washing liquid, and a suspension liquid, where the organic slurry washing liquid is obtained by washing the organic slurry with water, the char and ash washing liquid are obtained by washing the char and ash with a washing liquid, and the suspension liquid comprises water and lime; mixing the acidic liquid and at least one of the organic slurry washing liquid, the char and ash washing liquid, and the suspension liquid; adjusting an acidity level of the mixture of the acidic liquid and at least one of the organic slurry washing liquid, the char and ash washing liquid, and the suspension liquid to a predefined pH level; drying the mixture of the acidic liquid and at least one of the organic slurry washing liquid, the char and ash washing liquid, and the suspension liquid to obtain a powder, where the powder is used as a fertilizer; mixing the acidic liquid with raw biological waste for a predetermined number of times, where the predetermined number of times is based on an amount of the at least one nutrient absorbed from the raw biological waste by the acidic liquid; washing the char and ash with a washing liquid, where the washing liquid comprises water and sulfuric acid; adjusting an acidity level of the char and ash to a predefined pH level; and drying the char and ash to obtain a soil conditioner. ACTIVITY - Fertilizer.    MECHANISM OF ACTION - None given.
