In Switzerland, infrastructure construction is frequently discussed in regional sustainable development because it causes extensive movements of materials. But construction itself is of decreasing importance in industrial countries, as we expect a down-slow in growth of the built environment. Hence, the focus of research on sustainability is shifting to management of the existing building stock...

Swiss Legislation requires for all types of radioactive waste the safe and permanent disposal in deep geological repositories within Switzerland by stipulating a step-by-step procedure for site selection and licensing of the disposal facilities. Each step requires safety considerations or safety analyses which are reviewed by the Swiss Federal Nuclear Safety Inspectorate. The principle steps of...

In order to avoid the potentially devastating consequences of global warming and climate change, the carbon dioxide “CO2” emissions caused due to anthropogenic activities must be reduced considerably. This paper presents the first study examining the feasibility of carbon sequestration in construction and demolition “C&D” waste. Experiments were carried out in a self fabricated Batch Reactor at...

Metallurgical slag, including ferrochrome slag is internationally recognized as suitable material for use in road construction and as aggregate for concrete (Rossouw et al. 1981, Lind et al. 2001). Contrary to international practice, metallurgical slag – including ferrochrome slagis classified as hazardous waste that must be de-listed before use in other applications (DWAF 1998). Having adopted...

The ferroalloys industry has generated historically substantial solid waste. The accumulated waste causes serious problems to the environment. However, it is possible to transform the solid waste into an environment-friendly resource to serve the human being. Consequently, the construction of plants that are “environment-friendly” and that accommodate “recycling” has become a target of most fer...

In recent years demolished concrete waste handling and management is the new primary challenging issue faced by the countries all over the world. It is very challenging and hectic problem that has to be tackled in an indigenous manner, it is desirable to completely recycle demolished concrete waste in order to protect natural resources and reduce environmental pollution. In this research paper ...
