There has been very little investigation into the soil microbial community on green roofs, yet this below ground habitat is vital for ecosystem functioning. Green roofs are often harsh environments that would greatly benefit from having a healthy microbial system, allowing efficient nutrient cycling and a degree of drought tolerance in dry summer months. To… Read more »

We characterised four recycled materials that have been manufactured into useful substrates for use on extensive green roofs. These were a crushed red brick (the U.K. industry standard substrate base and therefore used as a control) and three alternative pellets made from: clay and sewage sludge (waste clay from excavations, fly ash and sewage sludge),… Read more »
PhD research conducted at Royal Holloway University of London 2006 – 2009 has shown that recycled aggregates made from waste materials, often sent to landfill, can be manufactured into effective green roof growing media (substrates).
Green roof research If you’ve ever peered down from a planet the vast expanse of grey, dull rooftops, or walked along a busy street and glanced up at the high-rises, you might agree that cities severely lack greenery. Cities are rapidly losing natural habitats and city ecologists are running out of space at ground level…. Read more »
