Elimination of organic waste from water
November 07, 2005University of Navarra researcher, Xabier Sevillano, recently defended his PhD thesis on a novel procedure for the elimination of organic waste from water. The chemist's work involved studying how one of the most noxious substances, phenol, could be eliminated. National and European legislations limit the dumping of this product. Nevertheless, many companies generate this toxic product in such a way that contamination of water by phenol is frequent.
To fight this contamination, Xabier Sevillano developed a bioreactor-a polymer capable of retaining the organic contaminants. On the surface of this polymer there arises a series of micro-organisms that destroy the phenol, removing the toxin from the flow of water which thus recovers its healthy state.
A clean, low-cost system
Apart from being a method whereby no noxious by-products are produced, the bioreactor developed in this research is a low-cost one and takes up little space - two very important factors for the companies involved. Also, the product has been tested in various conditions of water volume or flow, contaminant concentration and treatment time and has proved its utility in different situations. Thus, this novel technique adapts to industries with a variable generation of waste products, and which are obliged to treat them while not having other biological systems to do so.
The PhD results give hope to the introduction of clean, economic and highly effective purification processes.

Quicker microwave meals that use less energy may soon be possible with new ceramic microwave dishes and, according to the material scientists responsible, this same material could help with organic waste remediation.
Sulfur in marine archaeological shipwrecks -- the 'hull story' gives a sour aftertaste
Advanced chemical analyses reveal that, with the help of smart scavenging bacteria, sulfur and iron compounds accumulated in the timbers of the Swedish warship Vasa during her 333 years on the seabed of the Stockholm harbour.
Life at the jolt
Researchers at the Biodesign Institute are using the tiniest organisms on the planet 'bacteria' as a viable option to make electricity. In a new study featured in the journal Biotechnology and Bioengineering, lead author Andrew Kato Marcus and colleagues Cesar Torres and Bruce Rittmann have gained critical insights that may lead to commercialization of a promising microbial fuel cell (MFC) technology.
Engineered eggshells to help make hydrogen fuel
Engineers at Ohio State University have found a way to turn discarded chicken eggshells into an alternative energy resource. The patented process uses eggshells to soak up carbon dioxide from a reaction that produces hydrogen fuel. It also includes a unique method for peeling the collagen-containing membrane from the inside of the shells, so that the collagen can be used commercially.
Landfills, chemical weapon debris possibly a good match, computer model suggests
Putting building debris contaminated by chemical weapons into municipal landfills likely would pose only a minimal risk to nearby communities and the surrounding environment, according to a study scheduled for publication in the July 1 issue of the American Chemical Society journal Environmental Science & Technology.
More biogas, less sludge
Germany has more than 10,000 sewage plants, using costly processes to treat household, industrial and restaurant waste water. The treated water is discharged back into river and lake systems. What remains is an organic / inorganic mixture of sludge. The issue is how to dispose of this residue. Up to now, sewage sludge has been used as an agricultural fertilizer, burned to produce energy or dumped on landfill sites. However, legislation prohibiting the use of landfill sites for the disposal of organic waste is to be introduced in Germany in 2005.

Innovative Biotechnology Projects Secure Share Of £1m DTI Funding Stream
New cost effective and environmentally friendly ways of treating wastewater in the paper and textiles industries are among five projects to share almost £1 million in government funding, Science Minister Lord Sainsbury announced today. The projects are part of the Department of Trade and Industry's BIO-WISE Programme, which encourages UK manufacturing and service companies to drive up productivity by realising the economic and environmental benefits of biotechnology. Details of the five new projects are: · Thomas Chadwick and Sons in Dewsbury, West Yorkshire will receive a DTI grant of £354,879 to demonstrate how micro-organisms, lik
Fuel From Sawdust
Russia owns enormous reserves of coil, oil, and gas. However, such unconventional raw material in energy industry as biomass is of great importance. Its share amounts to 4 per cent now and, probably, will be increasing. Biomass, i.e. organic waste of wood industry and agriculture, trees of quick growth, is considered to be recoverable energy sources. Their reserves are recovered quicker in comparison with mineral resources. That is why in Russia and all over the world the technologies of processing biomass for energy industry have been developed for a long time. At the end of May, 2001 Head of All-Russian Scientific Research Institute of Electrification in Agriculture Professor Dmitrii Streb
Turning cakes and ale into fertilizer
Many companies, by nature of their business, produce waste material, and what to do with that waste can often cause problems, in terms of both cost and damage to the environment. Now, a Newcastle University research centre has been set up specifically to provide assistance to companies which produce waste materials that have the potential to be recycled for use on the land, as fertilizers, soil conditioners and contamination amerliorants. The Recycling to Land Research and Advisory Centre, based in the Department of Agricultural and Environmental Science at Newcastle University, and at the University's Cockle Park Farm, is a centre of excellence for the scientific evaluation of the suitabili
