I have two black bins from City of Mesa for composting, but get almost no useable compost. I add all my household useable waste and garden stuff (both dry and green), egg cartons and some torn up paper and cardboard bits. The bins are full. Recently I began leaving them open and watering them occasionally. They are sitting underneath huge pine trees so they get some sun, but not all day. The lizards, roaches and beetles love them. But I'm lazy and don't want to have to chop up the kitchen waste - or use electricity/gas for a chipper-shredder just to make compost, but what I'm doing is obviously not working very well. Help please?!
