Economic growth inevitably influences the food chain. Growing demand with changes in lifestyle and health consciousness encourage use of packaged and pre-prepared foods. The needs of environmental protection from waste generated are largely overlooked, and a lack of knowledge about the impact on the environment and its health effects constitute food security/safety problems. Food production and...

Taking LandSat TM/ETM+ images as information source, this paper used the Normalized Difference Water Index (NDWI) to extract mining subsidence-resulted surface water body information in Yanzhou coal mining area. It was found that the extracted water body information would be mixed with solid-waste dumps. Taking DN 40 in band 5 as threshold value, the water bodies and solid-waste dumps were iden...

Organic pollution is the term used when large quantities of organic compounds are found in waste water. It originates from domestic sewage, urban run-off; industrial effluents and agriculture wastewater. Water shortage and water quality are the main issues in the global water crisis. As the population increases, there is ever growing demand on water resources. Wastewater with organic pollutants...

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 ...

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...
