This invention relates to a method of producing a drum and paddle assembly for
the accelerated remediation of a contaminated material. The method comprises providing
at least one paddle which is connectable to, and extendable outwardly from the
periphery of, an elongate cylindrical drum. The drum has a longitudinal axis and
generates an air stream at a velocity sufficient for entraining the contaminated
material therein. Also, it is employed for microenfractionating the contaminated
material so that the contaminated material is treated with at least one chemical
amendment prior to, and/or during, and/or subsequent to, microenfractionating the
contaminated material. Each of the paddles comprises a body having a first planar
portion having a leading edge and a second planar portion connected at a first
angle to the first paddle portion. The second planar portion is oriented so as
to generate a first material-entraining air stream when the drum is rotated, and
a base portion connected to the body for mounting the paddle onto the drum. At
least one the paddle is mounted onto the drum.
