DIRECT-MAT – developing best practice on recycling or safe disposal of road materials in Europe
© Wasteconsult International (6/2010)
The European road network has a total length of more than 5.8 million km (ERF 2007) and it is still growing. Obviously, various pavement layers exhibit different lifetimes which makes regular maintenance work necessary. As a result, several hundred million tons of road materials are excavated each year from a number of demolished pavement layers. According to European policy (EUROPEAN PARLIAMENT, 2006), these materials can be seen as wastes, viz. “substance or object which the holder discards or intends or is required to discard”. Nevertheless, in nearly all countries, part of these road construction wastes is reused or recycled back into road infrastructure and this part may reach 100 % depending on the type of road waste.

Alternatives to wheeled loaders: Tracked conveyors and program-controlled conveyor belts have advantages:
© Deutscher Fachverlag (DFV) (6/2010)
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.

Environmental tools in building construction industry – A state of the art review for LCA applications in building sector
© Aristotle University of Thessaloniki (6/2009)
The research work to be presented in this paper aims at the comparison of different environmental tools for improving environmental, social and economic indicators towards sustainability in the building construction sector. Moreover, this work reviews in detail the LCA concept and the tools applied in the building environment, as an effort to bring together research on life cycle assessment and practical application.

Low-Cost-Techniques of Intensive Biodegradation and Maturation
© Wasteconsult International (6/2009)
Techniques for mechanical-biological treatment of solid fraction of household waste taking their seats in the waste management business of many countries. MBT facilities working as a complement or as a low cost option for incineration facilities. Further on there is still a large demand for many MBT facilities to improve the aerobic biological treatment process, to reduce operation costs and to increase reliability. With the help of some examples the possibilities to improve existing facilities will be shown and technical solutions for planning and construction of new facilities will be discussed. Keywords: MBT, aerobic treatment, composting, maturation, optimization, operating cost 1 Introduction 1.1 MBT – Current status and perspectives 1.2 Optimising potential 2 Optimising potential in aerobic treatment 2.1 The biodegradation process – Everything under control 2.2 The input material – flexibility counts 2.3 The financials – Efficient application of technology 2.4 Practical experience - Examples 2.4.1 MBT Cröbern 2.4.2 MBT Rosenow 2.4.3 MBT Schwanebeck 2.4.4 Dynamic tunnel composting – a pilot scheme 3 Summary

The use of ground bark and wood chips from a short rotation plantation for on farm composting: effect of tree species on the micronutrient content
© European Compost Network ECN e.V. (10/2008)
The effect of tree species on the nutrient concentrations of composts is assessed in this study. In the first part of the study, micronutrient levels were assessed in bark and wood of several poplar and willow clones in a 3-year old plantation.
