Compostables are materials that will naturally decompose quickly and can be used for enhancing and conditioning soil.

These include food scraps, coffee grounds and teabags, food-soiled or waxed cardboard, compostable containers, paper, plant materials, natural fabrics, and animal waste.

Before you would start a compost facility the best thing to do would be to speak to our partners, and to learn from their experiences.  This will help guide you on what to do and not to do before you start. The link below will take you to a list of partners, scroll to the bottom of the page to become a partner today!

The best way to go about starting a green bin/ organic waste pick up would be to discuss the topic and your ideas with your local city waste management officers.  If you do not know how to contact them then first reach out to your garbage man, then your local government representative for public works.

To have a compost pile you will need at least a 3 x 3 foot area to work with.  You will also need at least a cubic yard of organic waste to start composting.

There are many types of worm bins such as the Traditional Worm Bin, Flow Through Worm Bin, Stacked Worm Bin and Worm Trays which are discussed at the link below:

For home composting we would suggest a Flow Through Worm Bin due to its ease of use and simple construction.  They are also readily available for purchase from many vendors.

Traditional Worm Bins are probably the easiest to set up, consisting of a box or tub with holes made in it.  Although creating these types of bins is simple, maintaining and harvesting compost from them is more involved and can be messy.  There are many different designs some of which can be found on the following websites:

Flow Through Worm bins are more involved to create but are easier to harvest and maintain.  There are two main designs – one using boxes the other using fabric bags.  Designs can be found on the following sites:
