Ottawa, Ontario, Canada has a green bin program for composting. Kitchen scraps, tissue paper, yard waste, meat, dairy and other permitted materials go in the bin. Every week or two weeks in the winter (see the pick-up schedule here) you put your bin out at the curb beside your recycling bins and garbage for pick-up. The waste gets composted and sold to farmers as fertilizer for their crops.
I do worm composting in the summer but when the temperatures get below freezing I switch to using the green bin for the winter.
You can put a liner of some sort in the bin to keep the waste from coming into contact with the bin and for soaking up moisture. This is so that the bin itself doesn't start to smell and so that nothing sticks to the bin in winter. Paper bag liners are available for purchase but their use seems ridiculous to me, given that we're doing this to benefit the environment. Even though the bags are made of recycled material and get composted, recycling is just one step better than garbage and there are better options. After all, the bags do have to go through the recycling, manufacturing and distribution processes. I take newspapers or advertising flyers from other people's recycling bins and make my own liner as shown below. The liner gets taken away along with the waste material. If you don't put a liner you can just occasionally clean your bin with a hose.
Another approach instead of using a liner is to accumulate your waste in old newspaper in the kitchen until it's time to put it in the bin. At that time the waste is already in a liner, the paper it's wrapped in, so no additional liner is needed.
Even though the bin has a locking cover to close it tightly, I still put something over the waste to hold in any odors. When I put more waste in, I just lift some of the cover material and drop the waste underneath.
