Throwing away (or composting) food should be your last resort if you can't eat it or preserve it first. When food lands in a landfill, it's out of sight, out of mind. So what's the big deal? Well, food and lawn waste makes up 25% of all waste in landfills, which are so densely packed that oxygen isn't readily available. When oxygen is lacking during the decomposition process, the food emits methane gas, which is 20 times more toxic than carbon dioxide. All this methane is bad for the environment, and the inhospitable conditions of landfills make it difficult if not impossible for natural materials like food to break down properly. Each ton of organic matter we can divert from a landfill can save 1/3 of a ton of greenhouse gases from being emitted into the environment. Plus, composting can provide you with your very own "black gold" for free, allowing you to condition and enrich your soil, saving money and turning your food into nutritious fertilizer that will nourish future plants.
If you can’t think of a way to utilize extra foods and food scraps, composting is a better alternative than the trash. Think of it as a way to save the nutrients you’ve paid for by transferring them into new foods as you garden! Many foods can be composted, and it's a lot easier and sanitary than you might think. Check out SparkPeople's Composting Guide for Beginners to get started.
Overall, reducing food waste requires you to become more aware of what you’re tossing and come up with creative ways to utilize the scraps—or prevent them entirely. Becoming a leftover king or queen, being a savvy shopper, and serving up proper sizes will all help you become a more efficient user of food, saving you money and helping preserve our natural resources.
