Organics won't smell any more than your garbage does. You are simply moving the organics from the garbage cart to the organics cart.
Help prevent odors by using a collection container with a vented lid. Food waste decomposes and creates odors more quickly when access to oxygen is cut off. You can purchase a pre-made kitchen pail with a vented lid (with or without a carbon filter), or you can make one using an ice cream pail or other container.
Consider collecting your "wet" organics (food scraps, meat trimmings, etc.) in a large yogurt or cottage cheese container or ice cream pail and keep the container in your refrigerator or freezer. Dump the wet organics into a compostable bag and place the bag in the organics cart the night before your collection day.
