various industrial processes with a huge variety of products, materials and compounds create different kinds of pollution for human beings, so that the identification of environmental pollutants resulting from industrial units’ activities, especially in water resources seems necessary. the aim of this paper is to estimate the role of industrial units in contaminating water resources, through us...
This study aims to contribute to environmental justice research by examining how Native Hawaiians and Pacific Islanders (NHPIs), a relatively small minority group, are disproportionately impacted by environmental toxins. Proximity to three different environmental hazards is considered: toxic waste, industrial air pollution, and freeways. 2010 U.S. Census, Superfund, Toxic Release Inventory, and...
Industrial ecology (IE) promotes the development of industrial systems based on recycling of matter and cascading of energy through cooperation. In this paper, the local/regional industrial ecosystem approach is reflected in two examples from Finland. The local forest industry system is based on renewable resources, waste materials and energy utilisation between forestry companies, a saw-mill, ...
In the present study, media composition for high production of pectinase by Enterobacter sp. PSTB-1 in submerged fermentation was optimized using response surface methodology (RSM). Mango fruit processing industrial waste (MIW) was used as substrate (carbon source) as it contains high amount of pectin. Enterobacter sp. PSTB-1 used in present study has given pectin clear zone (PCZ) of 34 mm is h...
"study of the biological treatment of industrial waste water by the activated sludge unit"
the activated sludge process simply involves bringing together wastewater and a mixed culture of microorganisms under aerobic conditions. the system usually includes a secondary treatment given to the settled sewage, and requires an environment in which active microorganisms are maintained in intimate contact with wastewater in the presence of sufficient oxygen. in this study, the treatment of ...
Nowadays, industrial symbiosis is a key concept of industrial ecology, which studies material and energy exchange flows in the local industrial systems to reduce the costs, e.g., the wastes treatment cost, and to reduce the pollution, e.g., greenhouse gas emissions. An industrial park is a set of manufacturing businesses producing different products and by-products located at the same place (ci...
The report by the National Academy of Science Committee on Institutional Considerations in Reducing the Generation of Hazardous Industrial Waste examines key institutional, or nontechnical, factors that affect the generation of hazardous waste by industry. It provides a framework for evaluating public policies, both regulatory and nonregulatory, to reduce the generation of hazardous waste. The ...
Efficient treatment of pharmaceutical waste is a big challenge because of the enormous quantity, complexity and hazardous nature. Lack of implementation of effective treatment technology aggravates the situations further in the countries facing the challenges of rising population, increasing urbanisation and industrialization generating enormous quantities of industrial wastes. This paper criti...
The concept of industrial ecology have been applied to local and regional sustainability goals and policies in many countries. To promote the growth of green industry and the formation of a “recycle-oriented society,” the Taiwanese government also launched an ecoindustrial parks project in 2002. This research examines stakeholder perceptions of the environmental science and technology park (EST...
