Abstract
A system and method for long term storage of waste can include a comminuted material having a high surface area. The comminuted material can include particles of processed hydrocarbonaceous materials from which hydrocarbon products have been derived. The comminuted material can be contacted with a flowable waste material so that the flowable waste material is retained in the comminuted material. This flowable waste material is some material other than hydrocarbon products that have been derived from the hydrocarbonaceous materials. An encapsulation barrier can envelope the comminuted material and provide a secondary means of preventing escape of the flowable waste material.
