From Colin Grant, Bio-Logic Remediation Works

Caspar Henderson states that “all techniques for cleaning polluted soil are
more expensive than simply removing it” (“The other big issue”, 4 January, p
12). This statement is out of date and incorrect.
Bio-Logic Remediation Works uses ex situ bioremediation to clean
soils contaminated with hydrocarbons ranging from oils to tars rich in
polyaromatic hydrocarbons. Our treatment prices (usually £15 to £25
per tonne) on our numerous full-scale projects have always been cheaper than
local landfill costs (for more information see
http://www.biologic.demon.co.uk/bio-logic.html).
