open windrow composting

waste management

Quick Summary

Open windrow composting is a method of treating municipal solid waste by allowing the organic portion to decompose in long, low mounds. These windrows are turned regularly to provide air for microbes that break down the waste, reducing its volume by up to 50 percent. This process, which can take five to eight weeks, generates heat that kills pathogens. While requiring significant land, it's a biological recycling process for garbage and sludge, producing compost that can be used as a soil conditioner.1
