Abstract:

The growing request of energy by the global population, related to the improvement of life quality, has generated an increase of environmental pollution due to the massive use of fossil fuels. In this context, the development of new technologies may implement the use of biomass as a renewable source of energy and to generate value-added products. Particular interest has been dedicated to the lignocellulosic biomass. Coffee is one of the most popular beverages in the world and the second commodity traded after petroleum. One of his most abundant by-products is the spent coffee grounds (SCG), wh

Cellulose nanocrystals (CNCs) and cellulose nanofibers (CNFs) are of great interest as reinforcing phases for polymer matrix composites; however, CNCs and CNFs prepared by the sulfuric acid hydrolysis and TEMPO process, respectively, have been reported to lack the thermal stability necessary for incorporation in many polymer systems. We have compared the thermal stability of CNCs and CNFs prepared by the sulfuric acid hydrolysis, TEMPO, and AVAP® processes and the corresponding starting materials by thermogravimetric analysis (TGA).

The initial pressure inside the reactor was 8.0MPa for all the formation experiments. Three bed sizes were employed in order to observe the effects of the silica sand bed size on the rate of methane consumption (formation) and release (decomposition).

Abstract:

The accumulation of huge amounts of food wastes every year has led to environmental degradation and especially to significant loss of valuable material. Steady consumption of beer results in a steady output of residues. Brewer’s spent grain (BSG) is the most abundant by-product generated in the beer-brewing process. BSG consists of the barley grain husks together with parts of the pericarp and seed coat layer that is obtained as solid residue after the production of beer wort. Despite the wide range of possible applications, its main use is limited to animal feed or simply deposition to landf
