Food scraps make my bin smell, how can I reduce the odour?

Food scraps will smell in any bin regardless (it is the nature of that type of material). To help reduce the odour you can freeze potentially smelly scraps in the freezer until your green organics collection day. Placing green organic material, such as leaves, shredded paper and lawn clippings on top of food in the green organics bin can also decrease odour, as can leaving your lid open occasionally to let air into your bin to reduce the (extra) smelly bacteria that likes to chomp on your organics. Another handy tip is wrapping all food in newspaper or using compostable bags/caddy liners.
