When you take your empty containers to a Redemption Centre you're going to receive a full refund on each refillable container. So if you paid a 10 ¢ deposit, you're going to get 10 ¢ back (except for refillable beer bottles, where the refund is $1.20 per dozen.)
When you return recyclable containers, you get a 50% refund. That means if you paid a 10 ¢ deposit, you get 5 ¢ back.
As noted before, some of the money, 2.5 ¢ to be exact, is used by the beverage industry to help pay for the cost of the recycling process. This involves sorting and transporting the containers, and processing them (ie. crushing metal or glass, shredding plastic).
The other 2.5 ¢ goes to the Government's Environmental Trust Fund, which supports environmental education, conservation, and protection through both community and governmental projects.
The money that the Environmental Trust Fund receives from the Beverage Containers Program is set aside for specific use in promoting programs that reduce waste.
