Co-Processing
Co-processing is a relatively economic and applicable approach to incorporate biogenic carbon into transportation fuels. Co-processing of biomass and fossil fuels can be commercially realized through co-combustion, co-gasification, and co-pyrolysis pathways. Co-processing of biomass-derived oils and petroleum intermediates has been …

Journey of the Growth of Co-processing in India | SpringerLink
Co-processing is defined as a technology of utilizing wastes as resources in different resource intensive industries (RII). Although wastes can be utilized in some resource-intensive industries such as cement, power, steel, lime, glass, and refractories, the use of wastes in cement manufacture dominates the RII sector.

Concrete | MIT Climate Portal
Cement begins as crushed minerals that are heated in a kiln to make what is called "clinker." Clinker is ground into a powder, mixed with a few additives, and then blended with some other minerals to create cement. This process creates CO 2 in two main ways. The first is the chemical reaction that occurs as clinker forms.
