Our societies generate increasing volumes of organic wastes. Considering that we also need alternatives to oil, an opportunity exists to extract liquid fuels or even industrial solvents from these abundant wastes. Anaerobic undefined mixed cultures can handle the complexity and variability of organic wastes, which produces carboxylates that can be efficiently converted to useful bioproducts. Ho...

Today we are witnessing a global energy crisis due to huge energy demands and limited resources. Non-renewable energy sources are depleting and renewable energy sources are not properly utilized. There is an immediate need for search of alternate routes for energy generation. Microbial fuel cell (MFC) technology, which uses microorganisms to transform chemical energy of organic compounds into e...

The increasing awareness that there are limits to the availability of nonrenewable resources, as well as that there are limits to the biosphere’s ability to absorb wastes, are at the basis of the growing interest about Microbial Fuel Cells (MFCs) technology, with particular regards to their application to wastes treatment. MFCs, in fact, couple the direct electric power production to the degrad...

background: recently, the rapid increase in quantity and type of waste has resulted to environmental pollution and health hazards which serve as a major challenge to humans. the level of this waste can be so high that dangerous chemicals and biological contaminants can be found in ordinary household waste. major sources of waste in every city are mostly from care/health centers. hence, this stu...

Wastes produced during fermentation and distillation of crude sugarcane juice in rum factories were evaluated as a new source of waxes. The chemical composition of the crude wax extracted from adsorbat of the wastes on fuller's earth was studied by GC-mass spectrometry. Series of linear alkanes (C19-C33), and wax esters constitute the main components. In addition, phytosterols, triterpene methy...

As do many industries, colleges and universities encounter thorny problems in dealing with hazardous wastes. Industry and academia alike are saddled with the rising cost of waste management and face perpetual liability for costs of waste cleanup. Unlike many industries, however, colleges and universities generate small amounts of waste, most, but by no means all of which is generated in laborat...

Problem statement: An Anaerobic Digestion (AD) process, traditionally applied to wastewater and sewage sludge treatment, has a great potential in the valorization of foodprocessing industry wastes. Approach: This study is focused on the evaluation of the theoretical biogas and methane production of some food wastes, coming out from rice, hazelnut and wine processing, on the grounds of their phy...

This study examines investor reactions to the repeated public disclosure of environmental information about firms in the chemical industry and the effectiveness of this information as a decentralized mechanism for deterring their pollution. It shows that these firms incur statistically significant negative stock market returns during the one day period following the disclosure of the Toxics Rel...

Every year, a huge quantity of fishery wastes and by-products are generated by fish processing industries. These wastes are either underutilized to produce low market value products or dumped leading to environmental issues. Complete utilization of fishery wastes for recovering value added products would be beneficial to the society and individual. The fish protein hydrolysates and derived pept...
