AbstractThe abundant availability of solid agroindustrial waste, sugarcane bagasse from sugar mills and juice extraction units, can bepotentially beneficial for the production of fermentation based biochemicals, paper boards and power. However, its role incausing bagassosis, an acute respiratory disease among the personnel handling large dry deposits has also been detected. Disposal of liquid waste whey from dairy industries poses a formidable threat to the aquatic ecosystem due to high BOD and ...

High contents of colloidal and organic materials in municipal wastewater sludge cause problems in the process of dewatering. The filtering efficiency can be improved by chemical conditioning, but the effectiveness of mechanical dewatering is limited because flocculated sludge is highly compressible. Physical conditioners such as bagasse can be used to facilitate mechanical dewatering. This paper describes the use of bagasse pith (cane sugar waste fiber) to improve the dewatering process of mu...

Availability of alternate fuels for cogeneration helps to limit the amount of bagasse as fuel at sugar plants and make them available for other uses such as paper manufacture or ethanol production. Due to the increased awareness on the adverse effects of carbon dioxide emission on the environment, power plant operators are compelled to reduce emissions of pollutants during cogeneration. Selection of low pollutant fuels, tapping of renewable energy and use of efficient operating policies can help...

The utilization of agro-industrial waste as a potential substrate for producing enzymes may serve a dual purpose of reducing the environmental pollution along with producing a high value commercial product. Twelve different agro-industrial wastes were evaluated for extracellular BGL (β-glucosidase) production by a mutant of Bacillus subtilis on solid state fermentations (SSF). The Citrus sinensis bagasse was found to be the most suitable substrate with highest BGL titer (35 U/gds). Optimum ...

The aim of present study was the effective utilization of waste apple for high yield of ethanol using immobilized cells of Saccharomyces cerevisiae S-3S through fed-batch fermentation. Low cost biomaterial was also developed for immobilization. Immobilization was carried out on different inert supports (agar-agar, k-carrageenan, Ca-alginate, sugar cane bagasse and apple bagasse). The results revealed that immobilized cells of S. cerevisiae S-3S gave high yield of ethanol as compared to free c...

Considering world energy demand and its security, much attention has been focused on identifying promising lignocellulosic substrates to generate a variety of downstream fuels and chemicals. In response, a recent key research area has centered on hydrolysis of cell wall polysaccharides by various physical, chemical and biological means. Due to their complex chemical and molecular structure, there is a substantial knowledge gap in understanding of biomass recalcitrance and its relationship wit...

Inorganic thermal insulators are commonly used to improve energy efficiency. However, environmental and health aspects of their production until the end of life have been increasingly concerned. Agricultural wastes including rice straw, rice husk and corn cobs are abundant in Thailand and converted into value-added products such as thermal insulation materials offers a viable recycling opportunity as the ecological burden of a product has now become a widely-discussed issue. In this paper, gl...

The textile industry has been contributing to the generation of wastewater containing dyes during the dyeing process. In this sector, Reactive Blue BB is a dye used on a large scale. One method widely applied to dyes wastewater treatment is adsorption. This technique is inexpensive since it can apply industrial by-products as adsorbents. In this work, the adsorption of Reactive Blue BB dye by the sugarcane bagasse, a by-product from the sugar and alcohol industry, was evaluated in batch syste...
