Pulping byproducts
Energy and Electricity
Byproducts that are used to generate power or heat
Electricity: Surplus electricity generated during mill operations, often from black liquor combustion or cogeneration processes.
Energy: Thermal energy generated by burning black liquor, biomass, or other residues, used for mill operations or external applications.
District Heating: Heat energy supplied from the mill to nearby communities through district heating systems.
Biogas: Methane-rich gas produced by anaerobic digestion of organic mill waste, used as a renewable energy source.
Bioethanol: A renewable biofuel produced from the fermentation of lignocellulosic biomass, such as wood residues from pulp production. Used as a fuel additive or for energy generation.
Tall Oil Derivatives
Byproducts derived from tall oil, a byproduct of the Kraft pulping process
Tall Oil: A mixture of fatty acids and resin acids extracted during pulping, used in soaps, lubricants, and biofuels.
TOR (Tall Oil Rosin): Used in adhesives, inks, and coatings for its tackiness and durability.
TOFA (Tall Oil Fatty Acid): A raw material for surfactants, alkyd resins, and lubricants.
DTO (Distilled Tall Oil): A refined tall oil product for biofuels and chemical manufacturing.
LTO (Light Tall Oil): A lighter fraction of tall oil, used in surfactants and lubricants.
Chemical Byproducts
Specialized chemicals produced during pulping
Turpentine: A volatile byproduct from softwood pulping, used in solvents, fragrances, and resins.
Lignin: A complex polymer extracted from wood, used as a raw material in adhesives, binders, carbon black, and potentially biofuels.
Functional Chemicals: Includes various wood-derived chemicals such as lignin-based products, carbon black, and specialty additives for industrial use.
