Briquettes versus Pellets

Briquettes versus Pellets

Considering whether you should chose briquettes or pellets? Here are some arguments to why briquettes are an attractive alternative to pellets – because each has its advantages.

vs.

  • The main advantage of chosing briquettes is the tolerance and variety of raw materials that can be used.
  • Another advantage of briquetting is the lower investment and operation costs, which are normally significantly lower.
  • Usually briquette plants start from capacities of 250kg per hour and up, while industrial pellet plants start from 2000kg pr. hour.
  • The fuel values or calorific values for briquettes and pellets are similar.

For a quick overview, look at the following table:

Our claim is that you can supply your densified biomass to the energy plants at a lower price by making briquettes instead of pellets.
