Abstract
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, is 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 medium to create at least one product, such as an ink, a paint, a stain, a colored material, and/or a dye.

A method to create a pigment from a raw material, the method comprising the steps of:
- obtaining a dry biosolid from the raw material,
- wherein the raw material consists of municipal sewage sludge;
- carbonizing the dry biosolid using a heat source to heat a container containing the dry biosolid to create a biochar,
- wherein the carbonization of the dry biosolid to create the biochar occurs via pyrolysis;
- and
- reducing the size of the biochar until a predetermined particle size is reached to form a powder pigment.
A method to create a pigment from a raw material, the method comprising the steps of:
- obtaining a dry biosolid from the raw material,
- wherein the raw material consists of municipal sewage sludge;
- carbonizing the dry biosolid using a heat source to heat a container containing the dry biosolid to create a biochar,
- wherein the carbonization of the dry biosolid to create the biochar occurs at a temperature of 800° C. or less and an atmosphere under inert conditions;
- and
- reducing the size of the biochar until a predetermined particle size is reached to form a powder pigment.
A method to create a pigment from a raw material, the method comprising the steps of:
- obtaining a dry biosolid from the raw material,
- wherein the raw material consists of municipal sewage sludge;
- carbonizing the dry biosolid using a heat source to heat a reaction vessel containing the dry biosolid to create a biochar,
- wherein the carbonization of the dry biosolid to create the biochar occurs at a temperature sufficient to cause thermochemical decomposition of the dry biosolid in a controlled oxygen environment;
- and
- reducing the size of the biochar until a predetermined particle size is reached to form a powder pigment.
