Abstract

The prerequisite for this multi-step method was to separate food waste and scraps into different groups: A) vegetables and fruits, as cellulose carbohydrates containing fructose sugar; B) expired protein foods such as fish, meat, sausage, and eggs; and C) bread and coffee waste. Then they were processed in the following steps:

Step 1: After the packaging materials were separated, the pure materials were crushed in a mixer.Step 2: Organic residue soaking: The crushed pure materials were exposed to a temperature of 70°C in the first tank to destroy pathogenic bacteria such as salmonella. Then they were mixed with mesophilic and thermophilic bacteria using a circulation axis to be pasteurized. Step 3: The author designed the second tank, in which the temperature dropped by 20°C. This temperature is optimal for cellulase activity. As a result, cellulase activity in this tank desalinated organic fertilizer at this stage. The resulting material emerged from the reactor as a brown powder. Step 4: The resulting material was left outside the reactor for three weeks to mature in the tank. Step 5: After three weeks, organic fertilizers with different functions were produced. The first type of organic fertilizer, which is regarded as a germination miracle, was created by combining reactor powder with coffee waste at a 1:15 ratio and then adding ten mg of glucagon per liter to this mixture. The second type of organic fertilizer was made by mixing reactor powder with coffee residue and nettles at a 2:15 ratio and then adding 15 mg/l of cortisol. This hormone stimulates superoxide dismutase and improves growth index and seedling length‎.
