What Is Straw and How Is It Used
Straw is the dried stalk of cereal plants such as wheat, barley, and oats, left after the grain is harvested. It is commonly used for animal bedding, mulch, thatching, and crafts.
How Straw Naturally Degrades
When left in fields or stored outdoors, straw breaks down through microbial action and exposure to moisture and sunlight. Over months, it becomes brittle, loses structural integrity, and eventually fragments into small fibers that decompose into the soil.
Final Disposal and Recycling Options
Used straw can be composted, baled for animal bedding, or processed into bioenergy and paper products. Some facilities collect straw for biomass burning or recycling into packaging materials, extending its useful life before final disposal.
