Farming produces a huge amount of crop waste, including straw, husks, and stalks every growing season. Unfortunately, common disposal methods—burning, plowing the waste back into the fields, using it as animal feed, and even composting—release greenhouse gases (GHG) such as methane (CH4), nitrous oxide (N2O), and carbon dioxide (CO2), contributing to climate change and long-term risks to food security.
