Which type of waste commonly found in landfills can decompose under specific environmental conditions?

Putrescible waste is organic material that can decompose through the action of microorganisms, particularly under aerobic (with oxygen) and anaerobic (without oxygen) conditions existing in landfills. This type of waste typically includes food scraps, yard waste, and other biodegradable materials.

The decomposition of putrescible waste can lead to the production of gases such as methane and carbon dioxide, which are by-products of the breakdown process. When managed properly, this decomposition can be harnessed in landfill operations through processes like landfill gas collection and utilization. This is in contrast to the other types of waste listed, which do not decompose in the same way. Durable goods, for example, are generally long-lasting materials that do not decompose readily, while electronic waste and construction debris are composed of non-biodegradable materials that can persist in the environment and do not contribute to decomposition processes like putrescible waste does.
