TL;DR: In this paper, the effect of reducing mineral matter naturally present in sawdust from untreated poplar (Populus deltoide) wood and giant reed (Arundo donax) canes on pyrolysis kinetics was examined from comparative non-isothermal thermogravimetric measurements in the range 20-900°C, using raw and previously demineralized samples.
Abstract: The effect of reducing mineral matter naturally present in sawdust from untreated poplar (Populus deltoide) wood and giant reed (Arundo donax) canes on pyrolysis kinetics was examined from comparative non-isothermal thermogravimetric measurements in the range 20–900°C, using raw and previously demineralized samples. Estimated kinetic parameters reflected changes caused by demineralization, especially in the low temperature range (up to ≈450°C), likely due to catalytic effects of the minerals. Pyrolysis of the demineralized biomasses also induced an enhanced development in pore structure of the resulting charcoal, favoring its potential use in adsorption applications and/or as an improved intermediate product for further conversion into activated carbons.

TL;DR: In this article, the physical and mechanical properties of WPC from Sengon sawdust in accordance with ASTM D7031 were investigated and the withdrawal test showed that sheet metal screw type has the highest withdrawal strength compared to cut thread wood, and fine thread drywall screw.

TL;DR: In this article, aqueous ammonia soaking (AAS) has been used as a pretreatment method for the anaerobic digestion of three lignocellulosic biomasses of different origin: one agricultural residue: sunflower straw, one perennial crop: grass and a hardwood: poplar sawdust.
Abstract: In the present study aqueous ammonia soaking (AAS) has been tested as a pretreatment method for the anaerobic digestion of three lignocellulosic biomasses of different origin: one agricultural residue: sunflower straw, one perennial crop: grass and a hardwood: poplar sawdust. The methane production yield was evaluated in batch ex- periments at different organic loadings, in order to assess any inhibitory effects due to the pretreatment. The ex- periments showed that the increase of organic loading did not affect the final methane yield of either raw or AAS pretreated biomasses. Among the three biomasses tested, poplar sawdust exhibited the lowest methane yield, due to its high lignin content. AAS treatment led to an increase of the ultimate methane yields of all biomasses, with the in- crease in the case of poplar, sunflower straw and grass being 148.7, 37.7 and 26.2 %, respectively. AAS resulted in solubilization of hemicellulose and partial removal of cellulose for all biomasses. Higher cellulose degradation was observed in grass biomass, in which a different mor- phology than the other AAS treated samples, was shown in SEM images. No toxic compounds such as furaldehydes, were produced during AAS pretreatment.
