Hi there I am Florie, a horticulturist/Permaculturist, I've had my bin for almost 3 years the first time I got some compost from it, it was very very smelly because it was wet and anaerobic. Reason being I put liquid in there, now I drain every thing before I add it to the bin. I put in dry leaves paper or chopped up twigs and dealt with the smelly stuff by adding masses of dry leaves that I mixed with mown grass. This is nice rich carbon I mixed in with the sludgy mess and created a very nice rich balanced compost the best I have ever had but you have to keep mixing every day the smell disappears as it turns aerobic. My bin is over a hundred in heat at the moment recently I got some compost from it, it was still a bit wet but it did not smell bad.
