Anaerobic digestion is a process through which bacteria break down organic mattersuch as animal manure, wastewater biosolids, and food wastesin the absence of oxygen. This one is real hard. Some of the benefits are: Faster composting process (as fast as 6 weeks!) like shredded cardboard to create more air pockets. Drainage is crucial to ensure the correct moisture level. Then, we will present a few different types of anaerobic composting. One of the most critical advantages of composting is its ability to trap methane gas, one of the most harmful greenhouse gases. anaerobic processes produce fewer nutrients. That's all some people need to hear; they're instant converts. Composting may be divided into two categories by the nature of the decomposition process. Anaerobic composting could be considered one of those methods since the gardener doesnt need to do much work. 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. This method is slower than aerobic composting. Composting requires the input of quite large energy inputs to fuel and operate the equipment needed to aerate and turn the compost piles. Before we get into the benefits, as well as how to actually do anaerobic composting, lets talk a bit about the basic principles of this method. Anaerobic microorganisms predominate and produce intermediate compounds like hydrogen sulfide, organic acids, and methane, among others. This helps stabilize and innoculate the compost before using it on plants (thanks to the access to air and beneficial soil microbes). Last but not least, if you dont have as much time and you want to have the fermentation process done within a couple of weeks go for Bokashi. .

It will be exposed to oxygen and beneficial microorganisms before use. These include wood shavings, wood chips, cardboard, sawdust, and dry leaves. During aerobic composting, the only byproducts are water, heat, and a trace quantity of carbon dioxide. You can use 50 to 95% moisture in the container.

Actually, the stomach still holds the prize for acidic environments. For this reason, its best to limit how often you add scraps to the bin. than aerobic decomposition, leaving you with compost with a lower nutritional value.
