TL;DR: The protection afforded by wood ash admixed at 30% by weight was of the same order as that provided by admixing pirimiphos-methyl at 8.8 ppm.

TL;DR: In this article, the improvement in the biodegradability of polypropylene (PP) was observed by blending it with small additions (5%) of wood sawdust and wheat flour.

TL;DR: In this article, the effects of the operation temperatures and sawdust feeding rate on the gas composition, cold gas efficiency, and carbon conversion rate of biomass were investigated in a 10 kWth interconnected fluidized bed reactor with Fe2O3/Al 2O3 as oxygen carriers (OC) and pine sawdust as fuel.
Abstract: Chemical looping gasification (CLG) was investigated in a 10 kWth interconnected fluidized bed reactor with Fe2O3/Al2O3 as oxygen carriers (OC) and pine sawdust as fuel. The effects of the operation temperatures and sawdust feeding rate on the gas composition, cold gas efficiency, and carbon conversion rate of biomass were investigated. The fresh and used oxygen carrier particles were characterized by means of XRD, SEM, and BET. The results indicated that the sawdust was partially oxidized to syngas by lattice oxygen from the oxygen carrier. The syngas yield, cold gas efficiency, and carbon conversion increased with increasing operating temperature. Also, the concentrations of CO, H2, and CH4 in the syngas increased at the elevated temperature, while the CO2 fraction decreased. The feeding rate of biomass has a significant impact on the syngas composition and cold gas efficiency. There was an optimal value of feeding rate at 2.24 kg/h corresponding to the maximum cold gas efficiency in the tested reactor ...

TL;DR: In this article, the authors examined the production of briquettes for household use from biomass in combination with plastic materials from different sources and found that the behavior in the combustion is steadier because of the increase of oxygen supply.
Abstract: This work examines the production of briquettes for household use from biomass in combination with plastic materials from different sources. Additionally, the combustion characteristics of the briquettes in a common open fireplace were studied. It is clear that the geometry of the briquettes has no influence on the smoke emissions. When the briquettes have a small amount of polyethylene terephthalate (PET), the behavior in the combustion is steadier because of the increase of oxygen supply. The smoke levels are between the 3rd and 4th grades of the smoke number scale. Measuring the carbon monoxide emission, it was observed that the burning of the plastic in the mixture with biomass increases the carbon monoxide emissions from 10% to 30% as compared to carbon monoxide emission from sawdust biomass emissions which was used as a reference.
