By the time you open the first bin, all pathogens will be dead and the composted material will be ready to use. Packing tightly and ensuring that no oxygen is flowing through will allow the microbes to feed and ferment the organic matter. Aerobic composting involves using oxygen-dependent bacteria to complete the decomposition of organic matter. Only 1-2 turns are required, possibly even 0! It will also slow down the decomposition process significantly. Composting is an organic process driven by naturally occurring microbes that thrive in the moisture present around the organic waste. Just remember that when you remove them, they will be too acidic for plants or their roots. This can happen in certain seasons, such as during the spring and summer, when you have an abundance of grass clippings. Any time organic materials (like food scraps) decompose, they can be expected to produce methane and carbon dioxide. But anaerobic composting takes place in enclosed containers which shouldnt smell. (This is useful on an industrial scale for making biogas fuel, but at a home composting level, this means you will produce more harmful greenhouse gases). It is mostly produced in a closed system, perhaps in a plastic bag or a sealed bin or sometimes even in open exposed piles. This is a labor-intensive undertaking.
