Anything from a 5-gallon food bin to tumblers works well for aerobic composting. Once or twice a week is best. Aerobic composting involves using oxygen-dependent bacteria to complete the decomposition of organic matter. But anaerobic composting takes place in enclosed containers which shouldnt smell. Anaerobic decomposers get right to work, with no need for fresh O2. Environmental Benefits. Advantages of aeration can be reduced odor, nitrification of ammonia to nitrate (thus potentially reducing ammonia emissions and also having a nitrogen form that is readily crop-available but also more prone to leaching), and reduction of greenhouse gases (especially methane) compared to anaerobic treatment. However, when it comes to anaerobic methods, you are much better off with a digester bin or finding a non-toxic trash bin that is small/large scale depending on what your intentions are. Since its best to limit the number of times that the bin gets opened, youll need a pail to collect several days worth of kitchen wastes.

That will allow oxygen to enter the compost more efficiently and enhance its overall aeration. Most folks who compost rely on aerobic, aboveground decomposition. anaerobic processes produce fewer nutrients. Anaerobic activity generates less heat than air-loving aerobic microbes. This is one of the most significant advantages of this method. Oxygen is necessary to support the beneficial microbes responsible for decomposition. These are perhaps the primary reasons why most experienced gardeners recommend sticking with aerobic methods. The following examples of anaerobic methods might be worth investigating: Anaerobic composting is putrefaction or fermentation. The simple act of turning aerates the organic waste materials and allows air and oxygen into the mix.

This is why you eventually need to put the lid on an aerobic system and walk away. What Happens When Compost Becomes Anaerobic? Home-built systems can be either large-scale or small-scale. Even after the material has been left to decompose, its advisable to spread out anaerobic compost and rake it into the soil surface before use. The idea is that, over the course of a couple of months, the green and brown matter decomposes and ferments while keeping almost the same physical volume. This is essential for keeping the microbes alive and busy. Basically, you dig a hole, fill it with organic matter, and seal it with a layer of soil. Lastly, you will want to keep the trash bin about 3/4 full. The process of composting if done right has minimal effects, if any, to the environment. In an anaerobic system, you dont have to mix them with other materials or spread them out so that they wont turn into green slimy mush. Anaerobic composting, also known as anaerobic digestion, is piling organic waste and allowing it to decompose without using oxygen.

You will be able to source all of the essential elements in order to build a great compost pile without having to look too far! Basically, anaerobic composting of green/brown matter is similar to pickling fresh food. One of the most critical advantages of composting is its ability to trap methane gas, one of the most harmful greenhouse gases. You fill an enormous container with organic material, making rotation possible and regulating the humidity, airflow, and temperature. The anaerobic composting process slows down decomposition and has a highly unpleasant, pungent smell. . But what exactly is anaerobic compost, and is it a good idea? For an above-ground digester, start by drilling holes in the bottom of your bin or barrel. Good for you But have you ever considered combining the two things?
