In Search of Perfect Biomass Pellets: KSLA Award to Bio4Energy Researcher for Tackling ‘Critical Pitfalls’ in Production Process
- Written by Anna Strom
Just as the European Union institutions are nearing a crescendo in their debate about the use of forest biomass for energy, the Royal Swedish Academy of Agriculture and Forestry (KSLA) seems to send a message in support for smart bioenergy in its 2018 Award for Best PhD Thesis.
Characterisation and Densification of Carbonised Lignocellulosic Biomass, published in 2016 by the Swedish University of Agricultural Sciences at Umeå, is about just that. It investigates whether biomass from forestry residues or willow that has been pre-treated by various degrees of roasting, or torrefaction, can be turned into qualitative pellets.
However, he told Bio4Energy Communications, the process requires greater fine-tuning compared with pellet making based on untreated sawdust, which is usually the basis for making so-called white pellets.
“We have seen that it works, yes. The next step is the creation of a market for torrefied pellets. The problems related to the pelletisation process itself can be solved”, Rudolfsson said.
