I started a compost heap 12 months ago, its in a 200 Ltrs plastic container, however the compost of grass cuttings , garden waste etc. does not appear to be "breaking down", also the waste is cold.
It probably needs something to kick start it, suggestions I have had are LIME or URINE
Would any of the members agree with this or are there other alternatives

All help will be appreciated
