Backyard Composting

Choosing between a composter and digester

  • Would you consider yourself a gardener?
  • Do you need soil for your garden?
  • Are you willing to perform regular yard maintenance?
  • Are you able to dig a hole at least three feet deep?
  • Do you want to compost all your leaf and yard waste?
  • Do you want to compost your pet manure?
  • Are you concerned about attracting animals and pests?

If you answered yes to four or more of these questions, a composter is the way to go. You will have access to your own personal soil, full of nutrients and easily accessible.

If you answered no to four or more of these questions, a digester is what you need. You can dispose of nearly all of your organic waste including leaf and yard waste, pet manure, meat, fish and bones. This route requires little-to-no maintenance and will create a leachate packed with nutrients for your backyard environment.

Why Use a Backyard Composter?

  • keeps up to 30% of your household waste out of landfills
  • easy to use, can be used year round
  • helps the environment
  • compost will help your garden keep moisture in the soil after rain or watering
  • you will have less of a need for chemical fertilizers
  • cost free and chemical free soil enricher
  • provides plants with nutrients such as nitrogen, potassium and phosphorous

Backyard digesters

Visit our Items for Sale page to learn how you can purchase a backyard digester.

Backyard digesters are low maintenance and easy to use units that reduce the amount of food waste you produce, and provide a nutrient rich liquid fertilizer.

A Digester is a large tub sized container with a cap that is set approximately one metre deep into the soil. Digesters use heat from the sun, along with microbial activity to develop a rapid decomposition process. This process produces a nutrient-rich leachate that is absorbed into the soil.  Leachate helps in the break down of heavy soils and helps sandy soils hold more water. The nutrients created through the digestion process are easy for plants to absorb, and less likely to wash away in the rain.

Backyard Digesters can break down food waste, pet waste and small quantities of yard waste. Our digesters do not produce finished compost and do not require harvesting. The use of the Backyard Digester speeds up the decomposition of organic materials such as kitchen and yard wastes, and creates a valuable source of nutrients to your backyard plants while promoting waste diversion.

Why choose a digester?

  • keeps up to 30% of your household waste out of landfills
  • your waste is primarily reduced to water since it is digested, not composted
  • no additional water is necessary; the water enters the soil under the base of the unit
  • does not require additional soil
  • very little residue is produced and no air (anaerobic) or mixing is required
  • works well in small backyards where the goal is waste diversion as opposed to soil building

  • bread, rice and grains
  • fish, meat and poultry including bones
  • fruits and vegetables including peels
  • cooked foods
  • coffee grounds and tea bags
  • dairy products
  • eggs and shells
  • hair and fur
  • paper towels, napkins and tissues
  • soiled newspaper (shredded)
  • sawdust and wood ash (untreated)
  • animal excrement

  • metal
  • wood
  • plastic
  • glass
  • paper
  • straw
  • bulk oil
  • disinfectant, bleach
  • grass cuttings, hedge clippings
  • large amounts of course vegetable matter
  • large amounts of yard waste

  1. Pick a spot that is well drained with as much exposure to the sun as possible, but also convenient and accessible throughout the entire year. Make sure there are no cables, pipes or tree roots present where your hole will be.
  2. Dig a hole 90 cm (35") wide and 30 to 40 cm (12 to 16") deep in well-drained soil. If the area is comprised of heavy clay dig a hole 100 cm (40") wide and 40 to 50 cm (16 to 20") deep. To test the drainage of the area, pour a bucket of water into the hole. If the water disappears in 10 to 15 minutes your area is well drained. If it persists for longer than 15 minutes you may want to try a different spot. 
  3. Mix some soil from the hole with some stones or gravel and/or compost and use this at the bottom of the hole, as well as for backfill once the tub is in place.
  4. Ensure the bottom of the digester is below ground. 
  5. After installation is complete, begin adding kitchen waste, but limit the amount of meat, bones and fish added for the first 4 to 6 weeks. The materials added to the digester should be comprised of 98% kitchen waste, and no more than 2% yard waste (dry yard clippings, dry leaves and plants, dry sticks, hair and fur).
  6. You may choose to sprinkle some Compost Accelerator on your food waste for the first 5 to 6 times before placing it into the digester. This will help build up a healthy amount of bacteria.
  7. The waste should be covered in a blue/gray fur which should start to build up over the first 10 to 14 days. Don't be alarmed, this is normal. Compost Accelerator is not necessary when the fur is present.
  8. No regular maintenance is required. If you notice your digester is getting full and the waste is not breaking down you can try cutting your waste into small pieces, using the Compost Accelerator to speed up the breakdown or move your digester to a new location.
  9. The digester is designed to stay in one place and break down wastes quickly. You should never have to move it, but if you would like to access any finished compost that may be created, this would only be possible after a few years, and would require the digester to be dug up and relocated.

My waste isn't breaking down

You may find your waste is not breaking down fast enough; this could be due to the wrong materials being added (such as too much yard waste) or not enough volume of waste. Try cutting the food waste into smaller pieces for more efficient digestion. There may not be enough micro-organisms present; in this event you may chose to add some Compost Accelerator. Make sure you have a good load of waste to start the process.

My digester smells bad

You may notice that there is a strong odour present when you open your digester.  This is due to the anaerobic breakdown occurring (lacking oxygen), which is a normal process.  Keeping the lid on the digester at all times ensures no smell escapes and no oxygen penetrates the digester.

My digester is attracting animals and pests

In order to deter animals or rodents, you can use strong smelling spices (cayenne, paprika, etc.) surrounding the outside of the digester. If you live in an area where bears frequent, it is a good idea to avoid adding meat, fish, dairy, fruit, or grease during periods of high bear activity. They are also attracted to garbage cans, dirty BBQ grills, bird feeders, pet food, and citronella candles.  You may also choose to add soil or small amounts of pet waste on top of smelly food being added.

Should I avoid certain areas

If you choose to add large amounts of pet waste, meats, and dairy, avoid placing your digester close to your vegetable garden. These materials may contain different products that are unhealthy for human consumption.
