WHAT YOU NEED
You don’t really need a bin to start composting, however most people prefer to keep their composting materials confined and in some cases covered as well. You can simply create a compost heap in your back yard, however if you choose a compost bin, you will need to think about how much waste you generate and how much space you have available for composting . There are lots of options ranging from commercially available molded plastic bins to large multi-bin systems that you can build yourself. Check out our compost bin options section for ideas and plans for building your own compost bin. If you live in an apartment or don’t have a backyard, you should check vermicomposting indoors using Red Wriggler worms.
If you are composting outdoors in your backyard, the ideal location for your bin is on grass or soil, in a sunny (or partly sunny) spot. Choose a location that is convenient to access all year-round.
WHAT YOU can put in your bin
There are two main types of organics that can be put into your compost bin, “greens and browns.” Greens are wet materials rich in nitrogen while “browns” and generally dry and rich in carbon. You need both of these materials to make compost. The following chart provides information on what you can and what you cannot compost.
|Do Not Compost
|Vegetable and fruit scraps (fresh, cooked, or canned), coffee grounds/filters, tea leaves/bags, garden waste, fresh weeds without seeds, fresh grass clippings
|Dry leaves, straw, dry hay, sawdust, woodchips from untreated wood, twigs, dried grass clippings, dried weeds without seeds, shredded paper napkins, tissue paper
|Eggshells, wood ash (small amounts), plain rice, plain pasta, bread, hair, wool, cotton
|Meat, fish, eggs, dairy products, oily foods, bones, pet waste, weeds with mature seeds, plants infected with disease, plastic/petroleum products, metals, synthetic materials
Meat, fish, eggs, bones etc. can be composted using a food waste digester such as the Green Cone but should never be placed in your backyard compost bin.
A few other things that you need to know about the food you feed your compost:
- Start your pile with a generous layer of browns on the bottom.
- Alternate the layers of greens and browns.
- You should use 2 to 3 times as much browns as greens.
- The smaller the material the faster it will break down
- If you don’t have leaves you can use sawdust, straw, or even shredded newspaper for browns.
- Woody debris and larger material takes a long time to compost.
You do not have to distribute the layers evenly over the pile, however you should always cover the “greens” with a generous layer of “browns” to prevent odours and avoid attracting unwanted pests.
To make sure you always have some browns available, store some leaves in the fall for use the rest of the year round. You won’t really need them to compost all winter as the greens you add will be frozen anyway, but come spring you will need them.
You can also add soil at any stage of the layering process. A shovel-full of soil will introduce many soil organisms into your pile and acts as an accelerator. A thin layer of soil added on the top of your pile also helps to discourage pests and odours.

Other Things to Consider
Water and air affects the efficiency of the composting process. However, if you are not concerned about how quickly your compost is ready for use, then there is little else you need to do. Just feed your pile the right foods in the right proportions.
Your compost pile is full of living micro-organisms and if they are in a healthy environment, their population and activity will increase, which in turn increases the heat in your compost pile. The hotter your pile, the faster you get finished compost!
The micro-organisms in your compost pile need moisture in order to survive, however not too much or they won’t be able to breathe. Ideally your compost pile should have a moisture content of approximately 50%. You can easily check the moisture content by simply taking a handful of the compost and squeezing it in your hand. It should leave your hand moist and not drip more than a few drops when squeezed tightly. Remember that the “green” materials will be adding moisture content, however you may still have to add water. If your compost pile does not have a lid, you may want to cover it during heavy rains if it already has sufficient moisture.
The micro-organisms in your compost pile also need air. Aerating your compost is not a necessity, but it helps to speed up the decomposition process. If you do not aerate your pile it could cause the pile to begin to compost anaerobically, producing an unpleasant odour. If you want your compost quickly, you can stir you pile as often as every 3 to 5 days, however experience would show that stirring every 2 to 3 weeks will produce mature compost in about 6 months. In most cases that would allow you to harvest compost in the fall every year. Aerating will not only avoid this unpleasant odour problem, but it makes a significant difference in how quickly your compost matures.
You can aerate by turning the pile using a pitchfork or shovel or use an aerating tool to poke holes and make air channels throughout the pile. If you have a large compost pile, be sure to aerate all the way into the center so that the whole pile gets the air it requires.
Is it finished yet?
The composting process can take anywhere from a few months to a few years to complete. The length of time depends on balancing the right mix of materials, moisture content, and air. There are many different compost bins, and the specific type you have will have an effect on exactly how you harvest your finished compost.
Generally the compost is ready to use when it is dark brown, smells like earth, and crumbles in your hand. For more information on harvesting and using your compost, check our harvesting compost page.
Now that you know a little about composting, you’ll really enjoy or video. With the help of a couple of young filmmakers and some funding from Assiniboine Credit Union, we were able to produce this fun video on the basics of composting. Enjoy!
