Any time organic materials (like food scraps) decompose, they can be expected to produce methane and carbon dioxide. Depending on the setup, pulling the pan out without spilling its contents can be challenging, even impossible. Aerobic composting is the principle at work in aboveground composting environments whether it takes place in a freestanding pile or in a container that provides air circulation, such as a bin with open sides or a tumbler with aeration holes. However, because oxygen is required for biological life to thrive in soil, these organisms are absent (or in substantially lower numbers) in anaerobic soil. In aerobic composting, aerobic organisms use a significant amount of oxygen in decomposing organic matter to a relatively stable humus in suitable conditions. Make sure that the additions dont overwhelm the anaerobic process. Sunshine helps raise the bin temperature and keep the microbes happy. (Whereas aerobic methods tend to work better with more bulk), The by-products of anaerobes are different from aerobic organisms. The resulting parasitoids kill the pupa by consuming it. It changes the soil makeup, allowing better aeration and water retention. Make sure the material is wet; moisten it if necessary. Its only 1/20th as harmful. Composting and digestion are both proven methods of processing organic materials, particularly wastes, into value-added products using biological conversion methods. Another unfortunate by-product is the additional methane gas produced. Digesters produce large amounts of liquid which needs to drain away. Thus, once the bin is 3/4 full, you should simply be patient and let the acidic environment do its thing. These include wood shavings, wood chips, cardboard, sawdust, and dry leaves. If you have only heavy, clay soils, build a mound of dirt incorporating plenty of pebbles and situate your digester on top. Unfortunately, this type of composting also produces more methane, a potent greenhouse gas. In sandy soil, holes will probably suffice.
