A conventional, affordable method of producing compost is the open-air aerobic fermentation composting plant, and its manufacturing procedure is basically as follows:
1. Preparation of raw materials: The factory accepts garbage such as food scraps and biodegradable organic material. To ensure there are no foreign objects or significant contaminants (such as plastic, glass, metal, etc.) mixed in with the rubbish, it should first be sorted, cleansed, and shredded.
2. Combining the raw materials and adjusting the proportions: Combine the treated trash with the proper quantity of microorganisms, carbon sources, and inert materials (such as sawdust, straw, etc.). By raising the bacteria’ biomass, this step hopes to boost fermentation’s effectiveness and speed.
3. Moisture adjustment: To encourage the activity of microorganisms and prevent excessive oxidation, increase the mixture’s humidity to a reasonable level, typically between 40% and 60%.
4. Composting site: The mixture is delivered to the composting site, which is typically an open field. To prevent sewage from penetrating the soil, the ground is typically covered with an impermeable membrane.
5. Stacking: To help ensure that the mixture’s temperature is distributed evenly across the pile, the mixture is stacked into piles of modest size that are typically rectangular.
6. Aerobic fermentation: Following stacking, the compost goes through a natural process of aerobic fermentation. Microorganisms produce heat when breaking down organic matter in aerobic environments. The surface and top of the compost pile allow air to enter, which reacts with microorganisms to produce carbon dioxide and water vapor while removing heat and hazardous pollutants.
7. Turning: Composting must be turned during the aerobic fermentation stage to improve air circulation and encourage microorganisms that break down organic materials. To ensure even fermentation across the entire compost heap, the compost is often turned every few days and the components at the bottom and top of the heap are mixed.
8. Stabilization: The compost pile’s organic material is converted into inorganic material after a period of aerobic fermentation, and humus is created concurrently, providing a dark, organic fertilizer. Typically, this process takes weeks to months.
9. Screening and packaging: To prepare the stabilized compost for sale and use, it must be screened and packaged. Compost is typically screened into three particle sizes—large, medium, and small—and then packed and sold separately. After sieving, the remaining material will be compacted and landfilled.
Water Treatment and Air Emissions: Through specialized equipment, air (mostly carbon dioxide) and water vapor created during the composting fermentation are released into the atmosphere. A chemical or biological treatment apparatus is used to treat wastewater.
It should be noted that environmental factors like temperature, humidity, oxygen, and others significantly impact the open-air aerobic fermentation composting factory’s production process. As a result, it’s important to monitor and manage environmental factors during the production process to guarantee the quality and safety of composting sex. An open-air aerobic fermentation composting facility has a cheap production cost but also takes up a lot of space and is susceptible to environmental conditions. Therefore, when choosing the location of the plant and developing the production process, these aspects must be taken into account.
