Organic waste, such as eggshells, fruits and vegetables, flowers and plants, dairy products, meat, poultry and seafood, paper products, milk cartons, tea bags, and coffee grounds can be degraded by microorganisms and other living organisms via composting or digestion. This breakdown of organic matter into carbon dioxide, water, methane, or other simple molecules results in things like fertilizers, soil, and even energy production. While landfills produce methane gas when organic waste is disposed there through anaerobic decomposition; this process is troublesome due to its capability to have a more than 25 times stronger impact on global warming than CO2.
What Is Composting
During the process of food waste composting, various types of organic materials, usually regarded as waste products, are broken down to produce a rich and nutrient-filled soil conditioner or compost. This compost can then be used in many ways, such as for gardening or landscaping purposes, horticulture, urban agriculture, or organic farming. Furthermore, compost is extremely beneficial for the land since it serves as a soil conditioner and fertilizer, adds vital humus or humic acids, and acts as a natural pesticide for soil; not only that but also helps with erosion control measures, land and stream reclamation projects, wetland construction, and landfill cover. The composting process typically takes months to complete and involves shredding the plant matter before adding water along with measured inputs of air, carbon-rich materials, and nitrogen-rich materials. In some cases, organisms like fungi, earthworms, or other detritivores help to accelerate the breaking down of the materials.
Composting Mainly Involves Four Components:
Organic Matter: Organic matter primarily comes from plant materials and animal manure. Creating the best compost involves combining brown organic material such as dead leaves, twigs, and manure to provide carbon with green organic material such as lawn clippings and fruit rinds to supply nitrogen in a 1:1 ratio. To accelerate the process, these items should be chopped or mowed into smaller pieces for better surface area.
As part of composting, moisture also plays an important role. If the compost pile is too dry, the compost will compel slower. The wetness of a wrung-out sponge should be similar to the compost. In case a large amount of brown organic material is used, water should be added intermittently. Although the pile of materials is too wet, it should be turned and mixed well. More dry brown materials could also be added.
In the composting process, Oxygen is necessary for bacteria to break down plant material. The pile should be regularly turned and mixed, bringing items from the outside to the center, to make sure oxygen is available. This action is critical for a successful composting process and to maintain its odor. We should wait at least two weeks before turning the pile, letting the middle get heated up during decomposition. Once cooled off again in the center, this will signify that decomposition has taken place. To enhance the speed of decomposition, we can turn the pile more often.
Bacteria and other microorganisms are key players in the composting process. To allow them to do their job, organic materials, water, and oxygen should be supplied. As a result of the bacteria breaking down the plant material, heat is produced which accumulates in the center of the compost pile. If one desires to accelerate this process, more layers of soil or finished compost can be added. Commercial starters may exist but are not a requirement due to having the right carbon-to-nitrogen ratio (e.g., 1-part green organic material to 1-part brown organic material). Aside from bacteria, many larger organisms – such as insects and earthworms – also help in decomposing the materials that make up the compost pile.
Organic Waste Composting Machine:
Organic Waste Converter Machines are designed to treat and recycle solid and liquid waste materials. These systems perform a variety of functions, among them pasteurization, composting, sterilization, grinding, and pulverization which makes the output unrecognizable and has applications across several industrial segments of society. As an environmentally friendly option over incineration, plasma arc, or landfill dumping, composting machines provide users with usable end products such as fuel, soil compost, or building material while also reducing pollution. They do have indirect competition with other means of waste disposal in the market.
