And the Winner is… Both vermicomposting and traditional composting will allow you to turn organic material into nutrient-rich soil. Maintaining of aerobic conditions in composting prevent the anaerobic products which can be harmful for plant growth and generate foul smells not appreciated by residents surrounding the facilties. Is Recycling Good Or Bad For The Environment? Humans, Animals, The Environment, The Economy & Space. Aerobic fermentation is the decomposition of organic material in presence of air. While traditional composting can easily handle large amounts of organic wastes, vermicomposting cannot handle large volumes. Disadvantages of Composting.

Aerobic digestion of wastes using naturally produced heat reduces unpleasant odor and increases pathogen die-off. Disadvantages of Anaerobic Composting Putrification of organic materials can lead to very unpleasant odors, due to release of sulfur-containing compounds such as hydrogen sulfide Process requires a lot more time to produce usable compost compared to aerobic composting Windrow and aerated static pile processes have the flexibility to handle changing feed characteristics and peak loads, require relatively simple mechanical equipment, and are simple to operate. The method overcomes many of the disadvantages of the Indore method (below), such as the problem of heap protection from adverse weather, nutrient losses from high winds and strong sun, frequent turning requirements, and fly nuisance.

This can be a rotary drum or a large stainless steel lined container. Composting with decomposers that need air (oxygen) is the fastest way to make high quality compost without any foul odors. You still need general waste and recycling collection for plastic, rubber, glass etc. Ambient temperatures and weather conditions influence windrow and aerated static pile composting. Aerobic process, also called Composting, is a natural process that rot or decompose organic matter by microorganisms under some controlled conditions. The anaerobic process, which is essentially putrefaction (sorr… In-vessel reactors have limited flexibility to handle changing conditions and are maintenance intensive. (i) Windrow method—The windrow method involves the arrangement of compost mix in long, narrow piles or windrows (fig. Every hot compost pile needs some materials high in nitrogen (called “green materials”) and some materials high in carbon (called “brown materials”). Despite these disadvantages, anaerobic composting is the best way to go in some situations: You’re looking to dispose of a one-time load of wet, potentially smelly, or pest-attracting kitchen waste, such as you’d accumulate after a day spent canning fruits or vegetables, cleaning freshly caught fish, or organizing a big social gathering that generates food scraps.
