Breakage Strength of Wood Sawdust Pellets: Measurements and Modelling. [PDF]

Materials (Basel), 2021
Wood pellets are an important source of renewable energy. Their mechanical strength is a crucial property. In this study, the tensile strength of pellets made from oak, pine, and birch sawdust with moisture contents of 8% and 20% compacted at 60 and 120 MPa was determined in a diametral compression test.

Preparation of Polyurethane Adhesives from Crude and Purified Liquefied Wood Sawdust. [PDF]

Polymers (Basel), 2021
Polyurethane (PU) adhesives were prepared with bio-polyols obtained via acid-catalyzed polyhydric alcohol liquefaction of wood sawdust and polymeric diphenylmethane diisocyanate (pMDI). Two polyols, i.e., crude and purified liquefied wood (CLW and PLW), were obtained from the liquefaction process with a high yield of 99.7%.

Torrefaction and Densification of Wood Sawdust for Bioenergy Applications [PDF]

Fuels, 2022
In this study, wood sawdust as waste residue from wood processing mills was pretreated using torrefaction to improve fuel properties and densified to facilitate transportation. Sawdust was torrefied in a fixed bed reactor using inside temperatures (IT) of 230, 260 and 290 °C for 15, 30 and 45 min, residence time.

The Effect of Alkali Concentration and Hydrolysis Time on the Production of Oxalic Acid from Wood Sawdust Waste by Alkali Hydrolysis Process

Chemical Engineering Transactions, 2023
Mahogany wood is a type of wood often found in sawmills because the wood grows faster than other types of wood, so a lot of mahogany sawdust is wasted and not utilized in a product that is discarded and has economic value.
