Waste & Resources Action Programme’s publication explains how compost can be incorporated

The Waste & Resources Action Programme has published a guide to using compost in green roof systems.

Called Quality Compost in Green Roof Construction, it details the benefits of green roofs and how BSI PAS 100 compost can be incorporated into their substrates.

BSI PAS 100 specifies the minimum quality of a recycled organic compost made from materials including grass clippings, tree prunings and leaves.
