we now only have a tiny bin in the kitchen (Like the kind you might out in your bathroom)and this only gets filled up twice a week...even less in the winter when the wood burner is on cos almost everything gets burnt...so much can be used ...BUT they eventually fall apart and then have to be thrown - i use the polystyrene meat trays for seed trays etc in the garden but they do get worse for wear after a while and these cant go in the recycling bin - anybody know if they can be used for anything else once they get really tacky?
