A novel pigment and a method to create the novel pigment are described. A raw material, such as municipal sewage sludge, municipal compost, food waste, agricultural waste, forestry waste, agroforestry waste, biomass, and/or livestock waste, are screened, cleaned, and/or prepared. The raw material is digested by microorganisms to create methane and a biosolid. The biosolid is dried and then carbonized to create a biochar. The biochar is ground into a powder pigment until a predetermined particle size is reached. The powder pigment having the predetermined particle size is applied to a media to create at least one product, such as an ink, a paint, a stain, a colored material, and/or a dye.

The present invention relates to [1] a process for producing a pigment water dispersion, including step 1 of mixing a water dispersion (A) formed by dispersing a pigment (I) with a water-dispersible polymer and a water dispersion (B) of a self-dispersible pigment (II) to obtain a water dispersion (C); and step 2 of subjecting the water dispersion (C) obtained in the step 1 to heat treatment at a temperature of not lower than 40 C. to obtain the pigment water dispersion, and [2] a pigment water dispersion containing a pigment (I) dispersed with a water-dispersible polymer and a self-dispersible pigment (II), in which the water-dispersible polymer is adsorbed onto the pigment (I) and the self-dispersible pigment (II).
