Waste disposal strategy for better quality of life: Asia and Europe in search of solutions for controlled waste management
[1. Juni 2010, Britta Rollert]
The largely unregulated waste management poses grave problems in many Asian cities. The need to organize waste management systematically and communicate this to people requires a lot of awareness training, good networking, a clear focus on results and a great deal of patience. Key individuals on all levels must be involved in order to increase acceptance among the population. The Technologie-Transfer-Zentrum, ttz (Technology Transfer Centre, ttz) in Bremerhaven, Germany, is aiming to develop and locally implement a realizable model with 21 partners from Europe and Asia, within the EU project ISSOWAMA (Integrated Sustainable Solid Waste Management in Asia). The project was officially launched in Bangkok on February 11 and 12.  || mehr...

Hydrofluoric acid neutralised: Disposal bottleneck for uiquicl special waste elimination
[1. Juni 2010, Jörg Mueller]
A state-of-the-art plant for neutralising (highly) toxic liquid production residues, which was also planned according to the latest safety standards, started operation near Leipzig (East Germany) last year after taking just six months to build. This especially alleviates a bottleneck in the disposal of hydrofluoric acid caused by increasing demand for products in various industries.  || mehr...

Low-energy lamps create problem waste: The fate of the light bulb is sealed in Europe
[1. Juni 2010, Heinz-Wilhelm Simon, Martin Boeckh]
After 130 years, Europe bids farewell to the incandescent light bulb. Conventional bulbs are too inefficient, too expensive, and too harmful to the climate. But the switch to low-energy lamps is not without consequences for the environment -- not, at least, as long as there is no adequate disposal system for the mercury contained in the new lamps. All low-energy lamps, most of which are manufactured in Asia, contain the poisonous heavy metal mercury.  || mehr...

Landfill sites as a source of pests: Waste disposal often leads to problems with pests at the landfill site
[1. Juni 2010, Ingrid Körber]
In Germany, tipping untreated household waste has been banned since 2005. But the country still has numerous landfill sites, collection points and intermediate storage areas. Here, one specific problem has not been resolved it has only been relocated: vermin and pest infestation. However, pest control has to be limited to containing the problem. This article describes pest control methods that could be used throughout the world.  || mehr...

Fine-tuning the fire: Plant controls improve waste incinerator economics
[1. Juni 2010, Andreas Voigt]
Thermal waste incineration plants are generally characterized by strong fluctuations in fuel characteristics, such as calorific value and water content. To keep emissions low, furnace controls have to meet stringent design, parameter and ease-of-use requirements. For large-scale furnaces, it makes sense to use model-based control systems, such as those commonly used for years in oil refineries. The result is a reduction in operating costs and lower quantities of flue gas.  || mehr...

Low point of the recession now overcome: The steel sector is recovering
[1. Juni 2010, Martin Boeckh, Bernhard Schaaf]
The Chinese steel sector is recovering from the recession, at least for the time being. Since hitting rock bottom in mid-November 2008, prices have significantly recovered, the warehouses have reduced their excess stock, and companies are hoping that the government’s infrastructure programme will help them overcome the crisis, reports the ‘Asien Kurier’ in its March edition. The steel recycling sector will also benefit from the upswing.  || mehr...

The long arm of the East: China keen to get hold of German electronic scrap
[1. Juni 2010, Dr. Dipl.-Chem. Beate Kummer]
In future, energy and resource efficiency, as well as principles of closed loop recycling management will set the political agenda more than short-term economic growth. Germany is more than just a role model -- it will also be attractive as a supplier of raw materials for the Middle Kingdom.  || mehr...

Complete utilisation of plastics: A study looks at the consumption and utilisation of plastics in Germany
[1. Juni 2010, Martin Boeckh]
Consumption of plastic in Germany continues to increase. The issue of waste utilisation in Germany has been clarified: more than 96 per cent of plastic waste is now utilised. Consequently, plastics are an important resource even after their first usage phase.  || mehr...

Paper export with opportunities and risks: The financial crisis leads to market adjustment in the paper industry
[1. Juni 2010, Martin Boeckh]
The global financial crisis has also reached the German recycling industry. But as opposed to the banking and automotive industries, the recycling industry has not responded with panic or predictions of Armageddon. Admittedly, there are some problems with exporting wastepaper to China, but in Germany the industry sees more opportunities than risks. In any case, there will be some form of market adjustment. An important representative of the German disposal industry and an expert in the area of wastepaper expresses his views on the situation in the global market. Lutz Siewek is Managing Director of Nehlsen GmbH & CO. KG in Bremen (Germany), where he is also responsible for the company's entire raw materials business.  || mehr...

Hard work for the microbes: Soil remediation in a tank farm
[1. Juni 2010, Dr. Thomas Caro, Dr. Thomas Berger]
In a tank farm in Belém (Brazil) the soil was found to be highly contaminated. With the help of a biological process this soil is remediated by microbes and then reused at the site. Because the process was originally developed in Germany, it had to be adapted to suit the local climate. The entire operating crew are subject to the tank farm's technical safety regulations, which comply with international standards and are strictly implemented.  || mehr...

Nature to the rescue: Natural processes can reduce pollutants in groundwater
[1. Juni 2010, Hans Joachim Schmitz]
When contaminated sites are being remediated authorities and the companies concerned focus on contaminant loads in the groundwater. So-called natural attenuation processes have been increasingly monitored and used over the last few years. A collaborative research project, which has been working for more than six years in Germany, has now developed the scientific fundamentals to better understand the natural degradation processes. As part of the project, 24 contaminated sites were examined in detail.  || mehr...

Investigations of Site-Contaminations in China: Initial Site-Contamination-Investigation and -Remediation in China
[1. Juni 2010, Boris Jacoby]
Currently in China there is proceeding a serious intensification of the environmental law relating to future critical limit values and the obligation of accompanying measures. Also in China the assessment of possible financial relevant features of sites like hazardous waste contaminations and groundwater pollution is becoming more important. Nowerdays, the investigation concerning contaminations of sites in China is becoming necessary and interesting for German investors. Meanwhile, in the course of all-embracing Due-Diligence-examinations for site assessments in China for a German investor the R&H Umwelt GmbH from Nuremberg/Germany (R&H) already has performed several initial site-contamination-investigations including the initial investigation of the building-substance on industrial sites.  || mehr...

Merciless physics: Drivers and loaders are both responsible for load securing
[1. Juni 2010, Diplom-Verwaltungswirt (FH) Alfred Lampen]
Over the last few years, the subject of load securing has become very important. However, in spite of all the efforts some basic mistakes are still being made, meaning that many loads are not adequately secured. This results in major accidents with serious injuries and high levels of material damage – especially in domestic goods transport.  || mehr...

Alternatives to wheeled loaders: Tracked conveyors and program-controlled conveyor belts have advantages:
[1. Juni 2010, Rüdiger Christophel]
Wheeled loaders are still indispensable working machines in many companies – also in construction material recycling plants. They are used because of the long operating hours they are capable of. In addition to the final loading, in many cases intermediate stockpiles are created, although these can result in considerable costs and risks.  || mehr...
