While traditional composting is undoubtedly a highly effective way to recycle nutrients into a garden, several factors limit its usefulness in some situations. Primarily, those are the high volume of food waste that goes into a pile, the space require to contain such a volume, and the relatively long breakdown time of large pieces of food. A compost shredder addresses these issues, since smaller food scraps allow you to compost higher quantities in a smaller area. The higher surface area of shredded waste also improves contact with soil microbes and accelerates the composting process.
My shredder is more or less bare bones. It did not come with a handle at the time, and there was no lip around the top to prevent food from spilling over the sides. Additionally, a family of four produces a lot of compost, and using the shredder has become a frustrating time-sink. A stop at my local makerspace hooked me up with some components for automating the system.
