agricultural waste biomass generated from agricultural production and food processing industry are abundant, such as durian  peel, mango peel, corn straw, rice bran, corn shell, potato peel and many more. due to low commercial value, these wastes are disposed in landfill, which if not managed properly may cause environmental problems. currently, environmental laws and regulations pertaining to ...

abstract background: dyes are visible materials and are considered as one of the hazardous components that make up the industrial waste. dye compounds in natural water, even in very low concentrations, will lead to environmental problems. azo dyes are compounds with one or more –n=n– groups and are used in textile industry. because of its low price, solubility, and stability, azo dyes are widel...

An experiment was conducted as randomized complete block design with three replications and 14 fertilizer treatments in year 2014. The treatments were including the control, application of chemical fertilizers according the soil analysis, application of 15, 30 and 45 tons of municipal  waste compost per ha as simple and with 25, 50 and 75% of chemical fertilizers. The results revealed that the ...

A preliminary study, which establishes the treatment methodology of liquid waste containing sludge and uranium in the lagoon of the conversion facility has been performed. Properties of the liquid waste such as initial water content, density and radiochemical composition were obtained by analyzing the samples taken from the lagoon. In order to minimize the secondary waste resulting from treatme...

Environmental policies at the European and global level support the diversion of wastes from landfills for their treatment in different facilities. Organic waste is mainly treated or valorized through composting, anaerobic digestion or a combination of both treatments. Thus, there are an increasing number of waste treatment plants using this type of biological treatment. During waste handling a...

On the basis of key ways of oily waste treatment in Russia which has been described in the article and on the example of oil-contaminated soil (OCS) treatment there can be considered two most widespread technologies: bioremediation and thermal recovery. We developed the process flow sheet of the equipment (UT-2S) for industrial oily wastes treatment on the basis of high temperature air tight de...

To guarantee sustainable and dynamic waste management, the dynamic waste management approach (DWM) suggests an evolutionary new approach that maintains a constant flow towards the most favourable waste treatment processes (facilities) within a system. To that end, DWM is based on the law of conservation of energy, which allows the balancing of a network, while considering the constraints of inc...
