Torrefaction is the process of upgrading biomass for energy generation processes. The process involves breaking down biomass in the presence of nitrogen, atmospheric pressure, or heat (200-300 °C). However, the torrefaction process takes time, depending on the type of biomass being broken down.

The end product of torrefaction is a solid biofuel, which can withstand milling and combustion. Still, finding a torrefaction technology consultant is necessary to guide the process. By the end of the consultation, you’ll decide if torrefaction is suitable for your industry.

Advantages of Torrefaction

A torrefied product is easier to handle because of its improved characteristics. The torrefaction process is responsible for improving biomass’ physical characteristics. As a result, it becomes more economical to use torrefied biomass to produce energy.

The application is excellent, particularly for large-scale use. Moreover, torrefied products are homogenous solid fuels with higher energy and low moisture content.

For a better understanding, below are the benefits of torrefaction:

  1. Torrefaction Makes Biomass Easy to Disintegrate

The grinding process becomes harder with biomass that is difficult to break down. Here is where torrefaction comes in. The process makes biomass less difficult to grind.

As a result, about 80-90% less energy is used in the grinding or milling process. That means you save more energy and money in the process.

  1. The Torrefaction Process Makes Biomass Hydrophobic

Keeping biomass moisture-free is a process on its own. Moisture affects biomass in many ways, making it unusable. In fact, moisture contributes greatly to the degradation of biomass.

Torrefaction makes biomass hydrophobic (repellent to water). As a result, the following processes become easier:

  • Transportation: There is no room to worry about how to transport biomass. Without torrefaction, you need to think critically about transportation to prevent any moisture-based damage to the biomass. However, torrefaction makes the process cheaper and easier.
  • Storage: Since the biomass is water repellent, outdoor storage is a welcome option. Before torrefaction, you would have to look for indoor storage, meaning more money spent.
  • Preserved Energy: Without torrefaction, biomass re-absorbs a lot of moisture. Unfortunately, most of this energy goes off during combustion. Torrefaction allows for conversion into pellets, the best way to conserve energy.


  1. Prolonged Shelf Life

Biomass undergoes biological activities since it is susceptible to attack by mold. Luckily, the torrefaction process dehydrates microalgae, proteins, and carbohydrates. Therefore, attack by mold is impossible. In addition, the hydrophobic nature of torrefied products prevents decomposition.

  1. Removal of Smoke Producing Compounds

Industries that use biomass to fire their production processes need to reduce the amount of smoke produced. This reduction is crucial both for health and environmental conservation purposes.

Therefore, a torrefaction technology consultant is vital to advise on the best way to carry out torrefaction for this purpose. Industries should find professionals to make the process more efficient.

  1. Production of Mixed Biomass

The torrefaction process ensures a homogenous output from mixed biomass. Thus, you can source different types of biomasses, such as woody biomass. Afterward, you can pelletize this into one device. Moreover, torrefied pellets are stronger. 

More benefits of combining biomass are:

  • Improved fuel availability
  • Reduced cost of fuel
  • Reliable supply of biomass

Torrefaction has major benefits, including easier transportation, storage, and handling. Besides, the economics of torrefied products makes much sense. In addition, the surety of fuel availability makes torrefaction an important process of biomass conversion.
