This study aimed to produce bacterial cellulose from paper waste sludge (PWS) as a method of utilizing the source remaining pulp in material. Initially, PWS was hydrolyzed by sulfuric acid create an enriched-reducing sugar hydrolysate. One-factor experiments were conducted with fixed amount (5 g) investigate influence hydrolysis conditions, including water, addition, temperature, and retention ...

In recent years, concerns about environmental waste caused by petroleum-derived chemicals as well as the consumer's demand for high quality food products, have prompted people to pay more attention to developing biodegradable food packaging materials using natural resources such as cellulose fibers and chitin derivatives. In this study, chitin whiskers have been successfully generated by hydrol...

Abstract The membranes can be synthesized from organic and inorganic materials. One of the based materials used was a cellulose acetate membrane banana peel. Banana peel comprised 65% cellulose, therefore it had potential to processed into membrane. Cellulose are using mixture skin with 55% acetone 27% dimethylformamide phase inversion technique. SEM results pictured porous pore size about 5 μm...

This paper investigates the ability of insulation cellulose fiber powder (CFP) to be pelletized for its valorization as biomass fuel. CFP is a waste originating from manufacturing that lacks any method because boron salts content. A sugar byproduct and lignosulfonate (LS) were considered binders pellet process. Physical tests carried out characterize pellets’ performance. Chemical combustion st...

Environmental preservation is one of the key strategies addressing sustainable development. An awareness of environmental problems and potential hazards caused by industrial waste waters has prompted many countries to limit the discharge of toxic effluents. Mycoremediation play important role in the treatment of pulp and paper mill effluents containing numerous toxic substances like hydrocarbon...

Protease enzyme has lot of commercial applications, so the cost-effective production of protease using sunflower oil seed waste was carried out from Oerskovia xanthineolyitca NCIM 2839. The maximum protease production was after 24 h of incubation with 2.5 % oil seed waste concentration. O. xanthineolytica was found to produce two proteases-P1 and P2. The proteases were purified using 60 % cold ...

BACKGROUND Lignocellulosic biomass is a viable source of renewable energy for bioethanol production. For the efficient conversion of biomass into bioethanol, it is essential that sugars from both the cellulose and hemicellulose fractions of lignocellulose be utilised. RESULTS We describe the development of a recombinant yeast system for the fermentation of cellulose and xylose, the most abund...

The production of textile materials has undergone dramatic changes in the last century. Man-made cellulose fibres have played an important role for more than 70 years. Today, the man-made cellulose fibre industry is the worldwide second largest biorefinery (next to the paper industry). In the last few years, the interest in man-made cellulose fibres has grown as a consequence of increased envir...

The problem of degradation of agricultural residues from palm oil industry is increasing due to its expansion. Lignocelloulosic waste from these industry represent large amount of unutilized resources, this is due to their high lignin content. Since white rot fungi are capable of degrading lignin, its potential for the degradation of lignocelloulosic waste from palm oil industry was accessed. T...
