In Lethbridge, about half of the residential waste going to the landfill are organics, mainly food and lawn cuttings. Once disposed of in the landfill, organics contribute to methane emissions (a potent greenhouse gas) and the accumulation of toxic fluids in the landfill called leachate. But even worse is that the food you throw away also wastes valuable resources, beginning in the sea or on the farm until it reaches your belly.
About one-fifth of the food you buy at the grocery store ends up in the trash. This costs you about $1,700 each year, but it also costs our environment: wasting agricultural land to grow the food that ends up being thrown out; using fresh water to grow the food; over-use of fertilizers that end up in the rivers creating huge aquatic dead zones worldwide; herbicides and pesticides that disrupt soil ecosystems as well as negatively affecting insects, birds and animals; and waste of the energy used to package, transport and refrigerate the food before it arrives in your home.
It is roughly seven times better for the environment to use all the food you buy than composting the food you do throw away. But composting is the next best thing, as there are portions of the food you buy that simply cannot be used. Backyard composting is good, but municipal collection and industrial composting can compost many things that are not suitable for backyard technologies. Reduce first, compost as a last resort.
There are a number of things you can to do reduce food waste in your home. For those who have shopped while hungry, you will know that planning your meals and buying only what you need for those meals is a good start. You can improve by planning to use what you already have in the refrigerator. Use more of the plant, from root to stem. And all of those scraps you generate can be saved to make soup stock for another meal.
Organize your fridge so that you can see the food that will spoil more quickly. Freeze food that you may not use right away or, when you have an abundance, you can preserve or dehydrate food to be used later. “Best before” and expiry dates are general suggestions from the food manufacturer – do a sniff test, as it may still be good to use. If you are going to use a product right away, help your grocery store by buying the items on the shelf closer to the “best before” date. Encourage your grocer to discount food that would otherwise be thrown away. If you have purchased or grown too much food, consider donating it to a food charity while it is still good.
Most people are pretty good at eating what they buy, but it is amazing how much goes to the trash anyway. For a lot of good tips, tools, and resources, visit wasteless.ca (a project of Environment Lethbridge).
