End-of-Waste Criteria for Construction & Demolition Waste

image of End-of-Waste Criteria for Construction & Demolition Waste

This report presents the situation within the Nordic countries with respect to production and recycling of construction and demolition waste, in particular crushed concrete, in the form of aggregates, and discusses the conditions and requirements relating to environmental impacts for a possible application of the End-of-Waste option in the Waste Framework Directive. If this option is applied, the material may become a product and it will no longer be regulated by waste legislation. Regulation of crushed concrete under product legislation presents a number of challenges, particularly with respect to environmental protection. The report presents and proposes a methodology for the setting of leaching and risk-based criteria to be fulfilled by crushed concrete (and other waste aggregates) in order to obtain End-of-Waste status. It is further recommended to set impact-reducing conditions on the use of materials obtaining End-of-Waste criteria, and not to allow free use. It should be noted that the work described in this report was carried out during the period from 2010 to 2012.

Management of C&D waste in Sweden

Today, about 100 million tonnes of aggregate material are used annually in Sweden. The road construction industry is responsible for about half of this. Natural gravel and rock material of good quality is easily accessible in Sweden and there is a long tradition for road construction with unbound materials. However, as in other sectors, sustainable management of resources has commenced. This has resulted in the introduction of alternative aggregate materials, such as recycled aggregates or various industrial residues. Alternative techniques such as the use of bound layers and stabilisation are also making progress in order to achieve cost-effective and resource saving constructions. The background to this is a number of political objectives and control instruments together with administrative and technical measures. The overall idea is that it should be a matter of course to use alternatives when possible and thus decrease landfill and reduce extraction from gravel pits and rock quarries. In this way, the use of alternative materials prolongs the life of existing landfills and reduces the need for new pits and quarries. The Swedish environmental protection procedures are illustrated in Figure 9.
