Environmental Technologies

Technologies, such as water recycling, energy reduction, environmental remediation, carbon recovery, and waste conversion are needed to minimise ecosystem contamination. These reports describe the Waste 2 Gold programme and include waste water treatment/remediation and adding value to solid waste.

    Genetically Modified Forests: From Stone Age to Modern Biotechnology

    Rowland D. Burdon and William J. Libby
    This report traces the history of tree improvement, helping the reader to understand tree genetics, as well as real and imagined concerns of genetic engineering. Dr Rowland Burdon has been a researcher with Scion since 1964.
