What is compost?

  • Composting is a natural process that breaks down kitchen, lawn, and garden materials into a dark, earthy, soil-like material called “compost.”
  • This end product is made up of organic matter, microbes and nutrients that can be used to condition and fertilize your soil.

Why compost?

  • When food and yard waste biodegrade in a landfill where there is little oxygen, they generate greenhouse gases comprised of roughly half carbon dioxide and half methane.
  • Composting is one solution to reducing the greenhouse gases produced by our landfills.

Benefits of composting


  • Easy and fun way to be environmentally friendly
  • Cuts your weekly garbage almost in half

    • Compost can also remove heavy metals, solids, oil, and grease from stormwater runoff
  • Saves landfill space.
    • The amount of waste you send to the landfill will be reduced by 1/3 to 1/2

Now sure of your composting style? The SK Waste Reduction Council (SWRC) spent a year testing out different types of compost bins in Saskatchewan to determine the best bins for our climate and different lifestyles. They have a pretty cool infographic that summarizes the results, and an online quiz to help you figure out what method will work best for you!
