Greenhouse gases generated from food rotting in landfills could be reduced to help mitigate climate change. According the U.S Environmental Protection Agency, in the United States, food is the single largest category of material placed in municipal landfills, where it emits methane, a powerful greenhouse gas.
Does food in landfills release methane?
Food waste that decomposes in landfills releases methane, a greenhouse gas that is at least 28 times more potent than carbon dioxide. Wasted food that is composted can be used as a fertilizer on cropland, improving soil health and productivity.
How much methane does food waste produce in landfills?
Every 100 pounds of food waste in our landfills sends 8.3 pounds of methane into the atmosphere. Over 20 years, methane has 86 times the global warming effect of carbon dioxide.
Why food in landfills is bad?
Reduce Methane from Landfills – When food goes to the landfill, it’s similar to tying food in a plastic bag. The nutrients in the food never return to the soil. The wasted food rots and produces methane gas.
Who is the biggest contributor to food waste?
Vegetables are the major contributors to the economic cost of food lost and wasted (23% of total cost), followed by meat (21 %), fruits (19 %) and cereals (18 %). Meat’s contribution to the total cost of food wastage is clearly driven by its high producer cost per kilogram.
