The law of toxic substances dates back to Medieval England, but the present comprehensive federal regulatory scheme was developed over the past two decades. This article presents a brief overview of the federal law of air and water pollution, solid waste control, and the regulation of chemicals.

Water and wastewater management constitutes a practical problem for the food and beverage industry including the brewing industry. In spite of significant improvement over the last 20 years, water consumption and disposal remain critical from an environmental and economic standpoint. This paper gives an overview of the world beer market in order to highlight the heterogeneity in capacity of glo...

Biochar is the product of the pyrolysis of organic materials in a reduced state. In recent years, biochar has received attention due to its applicability to organic waste management, thereby leading to active research on biochar. However, there have been few studies using food waste. In particular, the most significant difference between food waste and other organic waste is the high salinity o...

conclusions experimental results showed that mcns is an excellent sorbent for removal of mercury ions from petrochemical waste water. in addition, highly complex matrix of this waste does not affect the adsorption capability of mcns. results an effective hg (ii) removal (99.8%) was obtained at ph 6, with 50 mg of mcns for an initial concentration of this ion in petrochemical waste water (5.63 m...

background fenton (fe2+ and h2o2) and modified fenton (fe3+ and h2o2) are two popular methods used in advanced oxidation processes (aop) and degradation of persistent organic pollutants (pops), such as dye compounds. in these processes, fe2+ and fe3+ as catalysts and h2o2 as the oxidizing agent are added to the reactor. objectives the aim of the current study is to assess the abovementioned met...

the long term effects of sewage water irrigation on soil properties and heavy metal concentrations at rohtak city, haryana (india) was investigated. at each location, soil samples were collected from the upper layer (0-10cm) for determination of various physico-chemical parameters. heavy metals (pb, cu, mn, zn, cd, ni, and fe) were also determined. the chemical analysis of sewage effluent showe...

water plays a vital and essential role in our ecosystem. this natural resource is becoming scarce, making its availability a major social and economic concern. use of a large variety of synthetic dyes in textile industries has raised an hazardous environmental alert. about 17 - 20% of freshwater pollution is caused by textile effluents. these effluents are recalcitrant to biodegradation and cau...

The most important necessity for life is water. Shortage of clean & fresh drinking water leads to suffering. This is mainly contributed by generation of sewage waste mixed with the water bodies, due to unplanned urbanization and has largely contributed to the causing severe water pollution. Pollutants discharged in waste waters can be toxic to aquatic life and cause natural waters to be unfit t...

Recent years have seen significant increases in the average heating values of wastes in Central Europe. Essentially, this can be attributed to recycling measures, separate recovery of waste streams, and treatment and processing procedures in modified waste management concepts. As a result of the above and due to the increasingly frequent application of energy recovery procedures for commercial ...

Vertical liquids addition systems have been used at municipal landfills as a leachate management method and to enhance biostabilization of waste. Drawbacks of these systems include a limitation on pressurized injection and the occurrence of seepage. A novel vertical well system that employed buried wells constructed below a lift of compacted waste was operated for 153 days at a landfill in Flor...
