Commercial composting is almost similar to regular composting in the garden, just on a larger scale. Unlike regular composting commercial composting facilities, the only difference encompasses several methods to deal with all kinds of organic waste, including meat and bones. Commercial composting facilities also require a higher degree of organization, especially in “pile” management and logistical coordination when collecting materials, alongside sensitivity to residents’ local environment and location—like regular, composting commercial composting facilities also require a range of inputs: green inputs such as nitrogen-rich food waste; brown inputs such as dry, carbon-rich yard trimmings; oxygen; and water.
They are the most useful to manage ever-increasing waste. This article will explain to you more about commercial composting facilities, their methods, and their problems.
Methods Of Commercial Composting Facilities
There three most popular and conventional methods in commercial composting facilities, which are as follows.
It involves piling the waste into long windrows between four and eight feet high and 14 to 16 feet wide. There is the periodical turning of waste to provide oxygen for decomposition. High temperatures generated by large piles can break down problematic materials.
This commercial composting facility is quite similar to the one that you use at home. Initially, there is loose piling of waste, then layering with bulking agents to allow oxygen to penetrate the pile. A larger-scale network of pipes will also blow air from the underside of the pile.
It involves the use of anaerobic reactions to break down waste, unlike the above two methods.
It involves placing the organic organics material in a large silo and providing a hermetic seal. The materials are subjected to periodical mixing.
Problems In Commercial Composting Facilities
Collecting the waste from residential areas safely and taking it up to commercial composting facilities is challenging due to the foul smell and risk of contamination.
Contaminated Waste Streams
The mixing of non-organic substances with organic is a major issue of commercial composting facilities. Some facilities are equipped with technology to get rid of harmful toxins, while in other cases, the harmful products may end up mixed with the final compost. In many places, the herbicide residues in compost are reported to kill garden plants.
Gasses And Leachate
Even the composting is considered circular; it still gives off harmful gasses (CO2 and methane) and leachate, polluting groundwater. It is still safer than at landfills.
Therefore commercial composting facilities are large-scale composting that is structured to handle a very high volume of organic waste instead of home composting, which handles organic waste from one household or area. They can be sold to farms and nurseries, applied to municipal landscaping, or sold to individuals. With the growing concern for the environment and sustainable living, commercial composting facilities are radically rising.
