Abstract Considered the issues of environmental protection with simultaneous use for neutralization and disposal urban waste containing substances organic origin, due to solar energy atmospheric precipitation. At present, in Russian Federation, makes up 90–98% all extracted natural resources, that is, industry works mainly production waste. Already 8 billion m 3 industrial municipal has accumul...

The article presents the results of research on influence lead production slag environment and ecology city. Due to open storage slags, an excess maximum permissible levels (MPL) was established: near plant, concentration in soil exceeds 3000 mg/kg, while MPL is 3.2 mg/kg. data analyzes obtained by methods scanning electron microscopy X-ray microanalysis, performed a microscope (SEM), as well f...

Presently in India, about 960 million tonnes of solid waste is being generated annually as by-products during industrial, mining, municipal, agricultural and other processes. Of this 350 million tonnes are organic wastes from agricultural sources; 290 million tonnes are inorganic waste of industrial and mining sectors and 4.5 million tonnes are hazardous in nature. Advances in solid waste manag...

The black cotton soil is a type of problematic expansive soil which causes many problems in the construction of structures founded on them. It is having a swelling and impervious nature with poor geotechnical subgrade characteristics. In this research an approach is made towards the way of improvement in the various geotechnical properties of black cotton soil such as index properties, swelling...

The microbial electrochemical cell (MEC) is a promising waste treatment technology to accomplish simultaneous alternative energy production and degradation of organic matters. Potato pulp waste (PPW) from a potato processing plant contains a large amount of carbohydrates that need be degradated before discharge into the environment. Here, we describe electricity generation in singlechamber micr...

Coal ash is the main waste from power plant. It is estimated that the consumption of the coal for power plant will increase to 240 million tons each year and the coal ash wastes will produce more than 2 million tons per year. Although the utilization of coal fly ash can be reached 74.1%, large amount of coal fly ash and bottom ash still cannot be utilized. The purpose of this research is to dev...

Production of biogas through anaerobic digestion (AD) from the organic fraction of municipal solid waste (OFMSW) was compared to incineration of the waste. At the moment, almost all of the OFMSW in Singapore is incinerated. Three different scales of biogas plants were compared to incineration: one large-scale biogas plant that can treat half of all OFMSW in Singapore; one medium-scale biogas pl...

Filtrates from feedlot waste were incubated under aerobic conditions to evaluate the availability of nutrients for cell production and to assess the capacity of indigenous flora to produce stabilized effluents. Incubation was carried out in 9-liter aerated jar fermentors. Three-fourths of the organic material and one-third of the nitrogen were taken up in 4 days; 90% utilization of organic mate...

As manufacturing industries become more cognizant of the ecological effects that their firms have on the surrounding environment, their waste streams are increasingly becoming viewed not as materials in need of disposal, but rather as resources that can be reused, recycled, or reprocessed into valuable products. Within the food processing sector there are many examples of value-added use of pro...
