Mulch, compost and backyard composter giveaways
Free pick-up! From spring to fall or until the first snowfall and while quantities last, Waterloo Region residents can pick up free compost and mulch at our transfer stations in Waterloo, Gate #2 or Cambridge.
Both the Waterloo Gate #2 and Cambridge transfer stations have compost and mulch available, while supplies last.
What you need to know:
- Maximum 5 bushels per vehicle
- Bring your own shovel and containers
- Wear closed toed shoes
We do our best to keep bunkers stocked but we can't guarantee that material will be available for pick-up. The mulch we produce can work well as an underdressing to suppress weeds and retain moisture. It is not decorative.
Free pick-up of backyard composters! Currently, we have a limited number of backyard composters to give away on a first come, first served basis to Waterloo Region residents at the Household Hazardous Waste area of the Cambridge transfer station location only. There are no longer any backyard composters available at the Waterloo transfer station. One backyard composter per household. Some assembly of backyard composters is required.
Backyard composting |
| Using a backyard composter is a great way to manage your waste at home.
Benefits of composting:
To learn how to set up and use a backyard composter visit the Compost Council of Canada's website. Can people in multi-unit buildings compost? Yes! First, check your lease/agreement and any by-laws for your building/condominium corporation. If you are in a townhouse unit with your own yard, consider having a backyard composter. If you are in an apartment, consider worm composting (vermicomposting): Worm Composting Canada. |
Yard waste composting process |
| Yard waste collected curbside and from our transfer stations is taken to our Cambridge transfer station. We receive approximately 20,000 metric tonnes of yard waste each year.
Brush and Christmas trees from our seasonal collection program are shredded into mulch. The mulch we produce can work well as an underdressing to suppress weeds and retain moisture. The remaining yard waste is brought to the outdoor compost pad area and put into long piles called windrows. Windrows are monitored weekly and turned occasionally to help maintain the temperature, moisture and oxygen levels. After 12 months the compost is screened; any organics that have not fully composted and any other material are removed. The compost is tested to make sure it meets Provincial standards and then we give it away to Waterloo Region residents! Watch the green bin and yard waste composting processes video. |
Green bin composting process |
| Green bin material collected curbside is brought the Waterloo transfer station and is temporarily housed in bunkers. A large portion of the organics are then loaded into large trucks and shipped to the City of Guelph's indoor Organic Waste Processing facility. Some quantities of organics are also sent to All Treat Farms in Arthur for processing.
In Guelph, unaccepted material is removed then the organics are shredded and mixed with some existing compost. Material is scooped and placed inside a series of tunnels. In the tunnels the temperature is controlled and turned up. Moisture in the form of mist is occasionally added to the material. After six to eight weeks the compost is tested to meet Provincial standards and is then sold to farmers and landscapers in the area. Watch the green bin to compost process video. |
