We've had that over here for a while now...it works great. We have 3 bins, compost (which we never use coz we have an actual composter down the back of the garden), green bin and black bin. The green bin is collected every 2 weeks and is free, so we pile everything (recyclable) thing we can into the green bin, which means we don't have to put the black bin out as many times as we used to, which has saved us money *breathes*
