there are enormous quantities of unknown composition of hazardous wastes in tehran without any control, safe disposal and treatment. this study was done to identify hazardous wastes and to control this wastes by establishing a treatment, storage and disposal facility. according to available statistics there are 4461 different industries in tehran, out of which sample were chosen each having ove...

Dr. Ghosh has presented a novel technique for the con­ version of Municipal Waste (MSW) to methane rich gas. Prior work has either permitted fermentation to proceed naturally (landfill gas extraction) or used conventional stirred reactors (DOE Ref COM facility). Proposed is to recycle leachate through a mass of solid waste to achieve volatile acids and then to convert the acids to methane in a ...

healthcare waste is a by-product of healthcare. poor management of these wastes exposes the community to infections, toxic effects and injuries. the purpose of this study was to investigation the qualities and quantities characteristics of infectious and domestic wastes of dehgolan clinics in kurdistan province. for this purpose health care centers was identify including hospitals, clinics, inf...

Supercritical CO2 fluid leaching (SFL) method using supercritical CO2 fluid containing a complex of HNO3 tri-n-butyl phosphate (TBP) was applied to removal of uranium from radioactive solid wastes. Sea sands, incineration ashes and porous alumina bricks were employed as matrixes of simulated solid wastes. Real radioactive incineration ash wastes and firebrick wastes were also subjected to the S...

Large amount of wastes is generated every year from the industrial processing of agricultural raw materials. Most of these wastes are used as animal feed or burned as alternative for elimination. However, such wastes usually have a composition rich in sugars, minerals and proteins, and therefore, they should not be considered “wastes” but raw materials for other industrial processes. The presen...

The co-production of bio-char and upgraded bio-oil by fast pyrolysis raw sulfuric-acid pretreated agro-industrial wastes (corn cob, sugarcane bagasse sunflower seed hull) was investigated to valorize as sources value-added products (VAPs) following the circular bio-economy system. To this end, proximate elemental analyses were performed, adsorption properties determined in products. Bio-char yi...

Lignocellulolytic enzymes play an important role in various industrial applications as well the sustainable valorisation of lignocellulosic materials. Enzyme production using fungi has shown great advantages such high enzyme diversity, efficiency, and availability solid waste raw Agricultural waste, abundant non-food competitive feedstock, can be used to produce fungal lignocellulolytic enzymes...

Recently, the states of Gulf Cooperation Council especially Saudi Arabia have a significant increasing urbanization, developing and population that created huge amount of household solid waste (HSW). These wastes have a considerable impact on both human health and the environment. The HSW in Jeddah City was dominated by organics, paper, plastics and other small components. Generally, the produc...
