In Sweden, moisture measurement technology developer Mantex AB has announced that it is installing a new generation Biomass Analyzer for Waggeryd Cell at its pulp mill in Vaggeryd.
According to a statement, the installation follows a Letter of Intent (LoI) signed between the two companies in February 2025, regarding measurement services with the next-generation Biomass Analyzer.
The new machine will initially be trained on-site at Waggeryd Cell to accurately measure content and ash content in biomass such as wood shavings, pulp chips, and bark, before transitioning to a commercial agreement.
Mantex and Waggeryd Cell have a multi-year collaboration behind them. Since 2022, Waggeryd Cell has been using the first-generation Mantex Biomass Analyzer for measuring moisture content in pulp chips from sawmills.
Reputation for innovation
The chips are purchased by the mill from sawmills and used as feedstock for BCTMP pulp production. Waggeryd Cell has a good reputation in the industry.
Through innovative thinking, continuous process improvements, and high automation, the mill has increased annual pulp production tenfold, from 20,000 tonnes to 200,000 tonnes.
With the Mantex Biomass Analyzer, the mill has developed an unmanned feedstock reception control, operational around the clock. The moisture analysis of delivered sawmill chips is carried out quickly and easily by the truck drivers themselves.
Measure additional parameters
On February 17, 2025, Mantex and Waggeryd Cell signed a Letter of Intent (LoI) regarding a measurement service based on the next-generation Biomass Analyzer, which has been developed to measure additional parameters in a wider range of woody biomass material.
With the expanded functionality of the upgraded equipment, Waggeryd Cell also intends to streamline reception and quality control of other purchased assortments used as biomass fuel.
We have so far significantly streamlined both reception and arrival control of purchased raw material with the Biomass Analyzer. Now we look forward to taking the next step to gain better control of our purchased biofuel as well, said Johan Krohn at Waggeryd Cell.
The updated analysis equipment was installed on May 20, 2026, and is being tuned to measure both moisture and ash in shavings, pulp chips, bark, and log chips. When the machine measures correctly on bark and log chips, the tuning and test period can be converted into a commercial agreement.
The agreement will be adapted to the functions and fuel range we add to the measurement service after the tuning period. Waggeryd Cell is a leading-edge mill and an important partner for us. Here, our technology contributes both to increased profitability and better resource utilization. The fact that we are now expanding the collaboration feels very gratifying, commented Gustav Melin, CEO at Mantex.
