DIRECT-MAT â€“ 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. â€śsubstance or object which the holder discards or intends or is required to discardâ€ť. 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.
Low-Cost-Techniques of Intensive Biodegradation and Maturation

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.
