Chitosan as an Environmentally Friendly Corrosion Inhibitor—A Review Open
Corrosion poses a significant challenge for industries such as automotive, marine, construction, and oil and gas, as it impacts the production of high-quality goods while keeping maintenance costs low. Corrosion reactions, including oxidat…
Micromorphology and native extractive behaviour of wood powder Open
The transition to a bioeconomy is attracting the use of wood powders for developing bio-based chemicals, fuels, and products to replace fossil-based products. Wood powder-based products depend on the properties and quality of wood powders.…
Combining behavioural TOPSIS and six multi-criteria weighting methods to rank biomass fuel pellets for energy use in Sweden Open
EU energy and climate policies continue to drive interest in biomass fuel pellets which can be produced from a wide variety of feedstock. The use of multi-criteria decision analysis (MCDA) to support feedstock selection has the potential f…
Forecasting Future Procurement Potential of Swedish Forest Biomass Using Forest Inventory Data Open
In the last 20 years the use of forest biomass for energy production and sawlog and pulpwood production has increased by 68%, 11% and 31% in Sweden. As Sweden is trying to achieve net zero greenhouse gas emissions by 2045, the high demand …
Wood powder characteristics of green milling with the multi-blade shaft mill Open
The quality of wood powders depends on the size reduction technology used to produce them. The pre-drying, chipping, and conventional (impact and attritional) size reduction steps, commonly employed in industry, act to degrade wood and dim…
The CO2 cutting cost of biogas from humanure and livestock manure Open
The European Union is accelerating its rollout of sustainable energy production and promotion of a circular economy. Electricity from biogas has synergy with energy-policy and rural-development goals yet its economic value is often convolu…
Investigating the influence of work piece geometry on the specific energy use in size reduction with a multi-blade shaft mill Open
This study investigated the specific milling energy of rectangular pine (Pinus sylvestris L.) boards using a new size reduction technology, which can produce fine wood powders in a single-step operation. Multilinear regression (MLR) analys…
Pelleting torrefied biomass at pilot-scale – Quality and implications for co-firing Open
The co-firing of solid biofuels in coal plants is an attractive and fast-track means of cutting emissions but its potential is linked to biomass densification. For torrefied materials this topic is under-represented in literature. This pil…

Raw natural rubber latex-based bio-adhesive for the production of particleboard: formulation and optimization of process parameters Open
In this study, bio-adhesives from natural rubber latex (NRL) were combined with starch and formic acid to fabricate jute stick-based particleboards (JSPs).
Using macromolecular composition to predict optimal process settings in ring-die biomass pellet production Open
This study was performed to investigate if the process settings that give high pellet durability can be modelled from the biomass’ macromolecular composition. Process and chemical analysis data was obtained from a previous pilot-scale stud…
Multi-blade milling from log to powder in one step – Experimental design and results Open
This study investigated a new technique for obtaining wood powders from whole logs (Pinus sylvestris L.) in a single-step operation. The performance of a prototype multi-blade shaft mill (MBSM) was evaluated using a designed series of expe…
Using the macromolecular composition to predict process settings that give high pellet durability in ring-die biomass pellet production Open
This study was performed to investigate if the process settings that give high pellet durability can be modelled from the biomass' macromolecular composition. Process and chemical analysis data was obtained from a previous pilot-scale stud…
