The trees are taken to a local facility – the same place where garden waste goes (brown bin waste). The trees are loaded into large outdoor heaps called Open Windrows and turned regularly. They take eight to ten weeks to break down into compost. The compost is then screened for any contaminates such as plastics and metals and will be graded. Oversized materials are removed and will be put back through the process until they have composted down. This is then sold to local farmers to be spread on farmland.
