The LIFE project EnBa has made a considerable contribution to improving management of demolition waste in the long-term. It has significantly improved understanding of demolition waste streams and paved the way for new approaches, technologies and legislation to improve re-use of waste emerging from this stream. At the end of the project, EnBa has produced an impact on deposited (24%) as well as on recycled (76%) waste streams.The project started by conducting literature research, interviews, workshops and round-table discussions with major stakeholders to explore the current understanding of construction waste streams. It then followed the demolition of six buildings, taking samples from walls, windows, ceilings etc. from the buildings, as well as mixed waste samples after demolition. A total of 258 samples were sent for laboratory analysis of key components.The project developed a methodology for characterising the composition of buildings from the samples taken, measuring overall substance flows and extrapolating this information to the national level using data on existing buildings and expected demolitions. It also created a database of hazardous and recoverable substances to facilitate easy recognition on a building site.The team assessed current practices and emerging trends in the demolition cycle. This included an assessment of modern ‘Design for Recycling’ approaches and likely future demolition waste composition, as well as a detailed analysis of current processes and technologies in building waste management in Austria. The project examined the gap between the existing legislative requirements for waste management and current implementation.The second half of the project focussed on bridging the gap between the now increased understanding of demolition waste generation and the operators in the demolition cycle, including public authorities granting demolition permits, and construction, demolition and waste handling companies. It promoted awareness of the life-cycle of building materials, examined different approaches for exploiting demolition waste, established recycling standards and promoted the concepts of ‘producer liability’ and a ‘building ID card’.Learning from the project’s work included that the potential to extract valuable materials – such as copper – from construction waste is extremely limited and that asbestos was unexpectedly found in old floor tiles. It is very difficult to separate waste materials into re-usable/recyclable components if they have been glued/mixed together during construction. Improved life-cycle planning is essential at the construction phase for improved construction waste management.However, perhaps the major achievement of EnBa came about through being well timed to input into important legislative changes, including a new legal definition of the end-of-waste stage in Austria and a new national five-year waste management plan. Both of these include the EnBa concepts of requiring an evaluation of hazardous substances and a waste treatment plan before demolition. The EnBa project has contributed crucial information on potential standards for re-use of recovered wastes as raw material.Further information on the project can be found in the projects layman report and After-LIFE Communication Plan (see "Read more" section).
