Torrefaction pretreatment is a mild form of pyrolysis that has the potential to produce high-quality raw material for making biofuel serves as replacement coal in bioenergy industry. Microwave-assisted torrefaction was conducted on white spruce sawdust (WSS) at temperatures 200 °C, 250 and 300 °C retention times 5 min, 7 9 min an inert environment. The process produces solid carbon, commonly kn...

The effects of ash and commercial fertilizers on the foliar nutrient concentrations and stand growth of Scots pine were studied in four fi eld experiments established on former cultivated peat soils. The aims were to compare ash types (wood, peat and coal ash), study the effects of ash treatment (pelletization), compare ash fertilization with commercial fertilizers, and to study the interaction...

This study aimed to develop an eco-friendly, lightweight, and synthetic aggregate (SLA) based on clay suitable for use in structural lightweight concrete. The researchers utilized the cold-bonded pelletization process agglomerate pozzolanic materials, specifically attapulgite extracted from a quarry, crushed into fine filler. appropriate calcination temperature manufacturing this as material is...

The aim of this study was to develop a pH responsive enteric coated extended release multiparticulate dosage form containing a model drug ketoprofen, a nonsteroidal anti-inflammatory drug used for rheumatoid arthritis. The drug loaded pellets in matrix form were prepared by using extrusion/spheronization method. The optimized pelletization method revealed that extrusion using 1 mm sieve plate a...

When applied in agriculture, the solid carbonaceous residue of anoxic thermochemical conversion of biomass (biochar) has variable effects on soil, crop yields, and climate mitigation. Biochar can be added to soil as powder or as pellets. While powdered forms have demonstrated effects on crop yields, they may release coarse and fine particulate that can be transported into the atmosphere during ...

Guayule (Parthenium argentatum A. Gray) is a desert-dwelling crop that can produce hard rubber for tires and has the potential to help meet water conservation needs of arid regions such as Southwest U.S. Previous work quantified cost environmental impact from guayule production. However, establishing economic viability domestic industry requires identifying value-added products residual non-rub...

BACKGROUND AND THE PURPOSE OF THE STUDY Olanzapine is an antipsychotic used in treatment of schizophrenia. This research was carried out to design oral controlled release matrix pellets of water insoluble drug Olanzapine (OZ), using blend of Sodium Alginate (SA) and Glyceryl Palmito-Stearate (GPS) as matrix polymers, micro crystalline cellulose (MCC) as spheronizer enhancer and Sodium Lauryl Su...
