Since 2004, Teesside University scientists (United Kingdom) under the BioReGen (Biomass, Remediation, re-Generation) project, have been researching on plants which can be suitably cultivated in brownfield sites (abandoned land areas which have been previously used for industrial purposes, most often contaminated by hazardous wastes). They have recently reported that reed canary grass was suitable, "because it grows well on poor soils and contaminated industrial sites". It could also be used as "an excellent fuel for biomass power stations and, on a smaller scale, boilers in buildings like schools". The grass, which can be processed into fuel pellets or fuel bricks, reportedly burns well, and does not add to greenhouse gases. More importantly, "reed canary grass produces a good, clean fuel without picking-up contamination from the soil", according to Dr. Richard Lord, leader in Environmental Geochemistry and Sustainability. The other test plants included willow trees, miscanthus, and switchgrass..
