Cellulose nanocrystals (CNCs) have shown remarkable application prospects due to their outstanding chemical and physical properties. In this research, cellulose were isolated from grass waste using alkali, bleaching acid hydrolysis treatments further used as nanofiller in polyvinyl alcohol (PVA) films. The valorisation of the waste, an eco-friendly sustainable low-cost precursor yields ~23.3% C...

In this study, endoglucanase was produced from coffee pulp waste by Bacillus amyloliquefaciens MTCC610. The effects of the fermentation parameters such as pH, temperature, and the carbon source sucrose with different percentages (2% -10%) were used in coffee pulp substrate. The endoglucanase production was assayed using carboxymethyl cellulose (CMC) as the carbon source. B. amyloliquefaciens MT...

Anaerobic digestion (AD) is a widespread microbial technology used to treat organic waste and recover energy in the form of methane ("biogas"). While most AD systems have been designed to treat a single input, mixtures of digester sludge and solid organic waste are emerging as a means to improve efficiency and methane yield. We examined laboratory anaerobic cultures of AD sludge from two source...

The aim of this study is the comprehensive planning for integrated management of solid waste at the industrial parks. The share of each industrial group including food, metal, chemical, non-metallic minerals, textile, electrical and electronical, and cellulose industries were 48.2, 14.9, 6.7, 22, 0.9, 0.6, and 6.5 percent, respectively. The results showed that nearly half of total industrial wa...

Cellulose is the major component of plant biomass, which is readily available and does not compete with the food supply. Hydrolysis of cellulose as the entry point of biorefinery schemes is an important process for chemical and biochemical industries based on sugars, especially for fuel ethanol production. However, cellulose not only provides a renewable carbon source, but also offers challenge...

Cellulose wastes of a wood and paper factory were used to produce activated carbon. Several chemical agents under various conditions were used for production of activated carbon and hence their adsorption properties have been evaluated. In addition the effect of process parameters such as raw material, chemical agent concentration, impregnation ratio, carbonization temperature, carbonization ti...

One of the urgent tasks is development new thermal insulation materials to improve energy efficiency construction. In this work, composites were obtained based on previously unused cellulose-containing waste. The theoretical and experimental substantiation possibility increasing water resistance heat-insulating composite has scientific significance. features supramolecular structure cellulose a...
