Renewable replacements for carbon black in composites and methods of making and using thereof
First Claim
1. A master batch for the production of composites, the master batch comprising a blend of carbonized biomass and a carrier resin, wherein the carbonized biomass has a particle size lower than about 100 microns, and wherein the concentration of the carbonized biomass in the master batch is from about 25% wt. to about 75% wt., and the concentration of the carrier resin in the master batch is from about 25% wt. to about 75% wt.

Abstract
Biocarbon is presented as an alternative to synthetic carbon black. Master batches having biocarbon for usage in raw plastics and/or the production of composites. Biocarbon is mainly derived from plant biomass, but other sources can be used. A method of producing the master batch: (a) pyrolyzing processed biomass in an oxygen-starved environment to produced biocarbon; (b) comminuting the biocarbon in a reduced oxygen atmosphere; (c) cooling the comminuted biocarbon; (d) mixing the cooled comminuted biocarbon with a carrier resin, thereby producing the master batch.
