Background Prevention of waste has the highest priority under the EU s framework directive on waste The construction and demolition sector is often the largest single sector waste producer with a generation of 30 % to 50 % of the total waste produced. Many successful initiatives on increased recycling; hence recycling rates up 90-95% not many initiatives to prevent waste from the C&D sector while there has been some focus on hazardous substances in buildings. 6 15 jun 2011 Waste seminar
Aim of study The present study has the aim of identifying and prioritising initiatives that lead to waste prevention in the construction and demolition (C&D) sector. The aim of the project is to: Produce a catalogue with best practices and background information Analyse existing prevention initiatives Dessiminate new ideas and concepts throughout the sector Inspire and engage all actors within the sector 7 15 jun 2011 Assessment of initiatives to prevent waste from building sectors
Definition of waste prevention The waste framework directive (2008/98/EC) defines waste prevention as: Prevention means measures taken before a substance, material or product has become waste that reduces: a) the quantity of waste, including through the re-use of products or the extension of the life span of products b) the adverse impacts of the generated waste on the environment and human health; or c) the content of harmful substances in materials and products 8 15 jun 2011 Assessment of initiatives to prevent waste from building sectors

Initiatives investigated Seven prioritised initiatives were assessed Each description of the initiative is supplemented by a case study. 32 Initiatives were identified and grouped into: 1. Reuse of building materials 2. Information campaigns 3. Waste prevention guidelines 4. Voluntary agreements 5. Identification of hazardous substances 6. Tool for registration of non-hazardous building materials 7. Certification schemes 11 15 jun 2011 Waste seminar
1. Reuse of building materials 5 European examples direct reuse / "second life" easy to implement Domain Contribution Legend Waste amounts ++ Waste impacts 0 Hazardous waste amounts 0 Costs for implementation ++ Costs for construction sector + Bureaucracy + ++ very positive + positive 0 neutral - negative -- very negative Employment ++ Transferability to other geographical areas + 12 15 jun 2011 Waste seminar
2. Information campaigns Low cost, many targets effect difficult to evaluate a need for more targeted and specific information (often to general) Domain Contribution Legend Waste amounts + Waste impacts 0 Hazardous waste amounts 0 Costs for authorities 0 Costs for construction sector ++ Bureaucracy ++ ++ very positive + positive 0 neutral - negative -- very negative Employment 0 Transferability to other geographical areas + 13 15 jun 2011 Waste seminar
3. Waste prevention guidelines provide realistic and practical, usually stepwise steps to minimise waste focus mainly on the design and construction phase of buildings rather than maintenance and disposal Domain Contribution Legend Waste amounts + Waste impacts 0 Hazardous waste amounts + Costs for implementation 0 Costs for construction sector ++ Bureaucracy 0 ++ very positive + positive 0 neutral - negative -- very negative Employment 0 Transferability to other geographical areas ++ 14 15 jun 2011 Waste seminar
4. Voluntary agreements often between public and private with specific targets (benchmarking for waste) success depends on participating stakeholders Domain Contribution Legend Waste amounts + Waste impacts ++ Hazardous waste amounts + Costs for implementation - Costs for construction sector -/+ Bureaucracy - ++ very positive + positive 0 neutral - negative -- very negative Employment 0 Transferability to other geographical areas + 15 15 jun 2011 Waste seminar
5. Identification of hazardous substances identification of hazardous substances in buildings that are to be demolished => for correct disposal huge potential for the reduction of hazardous waste Domain Contribution Legend Waste amounts 0 Waste impacts + Hazardous waste amounts + Costs for authorities - Costs for construction sector - Bureaucracy/Administration - ++ very positive + positive 0 neutral - negative -- very negative Employment + Transferability to other geographical areas ++ 16 15 jun 2011 Waste seminar
6. Tools for registration of nonhazardous building materials tools for the registration of materials without hazardous substances is to promote sustainable products in the building and construction sector ecolabelling aim of ensuring a safe environmental and indoor climate Domain Contribution Legend Waste amounts 0 Waste impacts + Hazardous waste amounts ++ Costs for authorities 0 Costs for construction sector 0 Bureaucracy/Administration - ++ very positive + positive 0 neutral - negative -- very negative Employment 0 Transferability to other geographical areas ++ 17 15 jun 2011 Waste seminar
7. Certification schemes standardising the high quality of a building s construction during its construction, use and disposal often focus on material use/efficiency and environmentally friendly disposal of building components (rather than prevention) Becoming more used why this could have high importance Domain Contribution Legend Waste amounts + Waste impacts + Hazardous waste amounts + Costs for authorities -- Costs for construction sector + Bureaucracy 0 ++ very positive + positive 0 neutral - negative -- very negative 18 15 jun 2011 Waste seminar Employment + Transferability to other geographical areas ++

Targets for waste prevention Most initiatives have not been evaluated and measured. The three most commonly used indicators on construction and demolition waste in the EU are: Construction and demolition waste landfilled, Recycling of construction and demolition waste and Total generation of construction and demolition waste. 20 15 jun 2011 Waste seminar
Setting targets The study proposed, based on the data availability and consideration about the best available and best wanted indicators, to include three core elements. Domestic extraction and import/export of construction materials (DE), Construction and demolition waste generated and (CDWG) Physical activity in the construction sector (PA). 21 15 jun 2011 Waste seminar
Setting targets Gross domestic product (GDP) Output of the construction sector (OUT) Area of new construction (PA) Proposed combinations Domestic extraction 19 (DE) C&D waste generated (CDWG) C&D waste landfilled (CDWL) DE/GDP CDWG/GDP CDWL/GDP DE/OUT CDWG/OUT CDWL/OUT DE/PA CDWG/PA CDWL/PA (DE+CDWG)/GDP (DE+CDWG)/PA (DE+CDWL)/GDP (DE+CDWL)/PA Source: Bio Intelligence 2009 22 15 jun 2011 Waste seminar
Challenges in setting targets Availability of suitable data on waste generation from the building and construction sector. Data from the countries varies from 68 kg to 4700 kg per citizen The effects of the different initiatives are very uncertain and rarely quantified in respect to waste generation waste generation from the sector is produced many years after construction and consumption of materials 23 15 jun 2011 Waste seminar
