System and method for making cement and cement derived therefrom

Abstract

Integrated cement production systems and methods implementing the systems are disclosed, where the integrated cement production systems include a burnable fuel supply subsystem, a cement raw material supply subsystem, a kiln subsystem and a cement clinker composition storage subsystem. The burnable fuel supply subsystem is adapted to receive one or a plurality of used and/or unused healthcare materials. The burnable fuel supply subsystem can feed the materials directly into the kiln subsystem, can convert the materials into different form and feed the different form to the kiln subsystem or feed a combination of the materials, different forms and optionally conventional fuels to the kiln subsystem.
