Abstract
A waste material improvement and reuse method involves identifying an available material having a crush resistance that does not meet a requirement for use as proppant, but which can be improved to meet the requirement, and modifying a surface of the available material to improve the crush resistance to meet the requirement by applying a binding agent and/or an encapsulating agent to the available material, forming clumps of particles of the available material and increasing crush resistance.
