Conventional biomass pellets

ANDRITZ supplies complete plant solution as well as manufactures key process island such as grinding, pelleting and drying solution for converting wood, wood processing and forest residues, as well as agri residues and energy crops, into uniform, densified fuel pellets for large-scale power and heat generation, residential heating, and use as raw material for further downstream processing

Biomass pelleting solution

With 40 years of experience in biomass processing and over 180 years in pelleting technologies, ANDRITZ delivering state-of-the-art biomass processing solutions and key equipment. Our technologies power sustainability by minimizing total cost of ownership and maximizing energy efficiency. Take a look at our numerous solutions for pelleting solid biofuels.

Advanced solid biofuels

Advanced solid biofuels represent a significant evolution in the field of renewable energy, designed to further increase the efficiency and sustainability of biomass as a fuel source. These biofuels are engineered to enhance the advantages offered by conventional wood pellets, making them a superior alternative for decarbonizing energy production.

They are a type of biomass fuel that undergoes additional processing and refinement to increase their energy density, fixed carbon content, durability, and overall performance.

Torrefaction

Used in the steel and cement industry, where higher fixed carbon content is important. Take a closer look at our torrefaction systems.

Steam explosion

Drop-in fuel for coal-fired heat and power plants, especially useful because of high grindability and water resistance as well as pre-treatment for gasification. Take a look at our solutions.
