Abstract
A method and apparatus for comminuting and decontaminating discrete batches of waste material to reduce the volume, to render it unrecognizable and to render it safe for subsequent handling. The minimum volume of decontaminant fluid to be added to each batch is determined by its weight. Batches of differing weights are fed consecutively to the comminuting apparatus either manually or by a conveyor. A batch weigh scale is employed to preset a timer which controls the duration of operation of a device feeding decontaminant fluid to the batch. The feeding means can be made operable to withdraw reactive agents from separate storage means, to mix them to produce the decontaminant fluid and to feed the reacted mixture into the comminuting apparatus.
