Composting food waste reduces methane emissions from landfills. Food waste in landfills can produce 0.25 metric tons of methane per metric ton of food over 120 days, which has a warming effect equivalent to 6 metric tons of carbon dioxide. The document describes an experiment using worm composting to recycle food waste. Worm composting involves using worms and humus in a bin to break down food scraps into soil. Through this experiment, the author learned that composting is an easy, fun, and cost-effective way to recycle by turning food waste into usable soil rather than sending it to landfills.
