4 Definition According to the revised Waste Framework Directive, waste prevention embraces all the measures taken before a substance, material or product has become waste, that reduce the: the quantity of waste, the adverse impacts of the generated waste on environmental and human health, and the content of harmful substances in materials and products.
5 Background Limitation of unnecessary consumption Design of products that generate less waste Reuse, repair, refurbishment BEFORE they are discarded Actions of strict avoidance Forms of prevention through diversion of waste flows WASTE PREVENTION ATHENS 2014

9 The project
10 The project WASP-Tool application The Waste Prevention Decision Support Tool (WASP-Tool) is a web-based decision support tool designed to assist Local Authorities to select and implement the optimum waste prevention programmes for their local circumstances and prepare their Waste Prevention Strategies. The WASP-Tool utilises the information and analysis from the extensive State-of-the-Art review and is developed in Greek to reflect Greek and Cypriot waste data, context and waste prevention potential, with selected information material available in English (for example, recipes of Mediterranean cuisine utilising food leftovers). The tool is mainly developed by Harokopio University, using the input regarding current waste characteristics, management practices and local social, economic, and cultural conditions / habits from the other participating partners.
11 Design and Development of the WASP Tool The WASP-Tool is a web-based decision support tool designed to facilitate the selection and the implementation of the optimum waste prevention scheme for the participating LAs The WASP-Tool is developed in two stages: design and development of the WASP-Tool, and refinement of the WASP-Tool and update of the Waste Prevention Strategies-WPS) of the Project s Technical Part. The first stage is completed while the second is was started in June 2014.
12 Design and Development of the WASP Tool Architecture of WASP Tool To assist LA s to prepare and/or improve their waste prevention strategy
13 Design and Development of the WASP Tool WASP-Tool Indicators used in the WASP-Tool reduction of the produced waste quantity (tn/year) potential CO 2 reduction (kg/year) waste diverted from landfilling (tn/year) implementation cost (5-year in ) number of employment positions created implementation difficulty (scale 1-3) required citizen behavioural change (scale 1-3) appropriateness for application on a local level (scale 1-3) The target materials (biowaste, metal, plastic etc) for each waste prevention strategy are indicated
14 The WASP Tool Actions The knowledge base incorporated in WASP Tool stores data concerning the environmental impact of the following categories of waste prevention actions: Home composting Act against food waste generation Encouraging refillable and returnable packages Promoting reusable bags Reducing paper use in the office Reducing unwanted mail and advertising leaflets Promoting furniture repair Promoting WEEE prevention Donation/ repair of clothes and shoes
15 Design and Development of WASP Tool WASP-Tool WASP Tool is designed for non-expert users; for this reason, optimal values for each step of the process are predefined in the system.
16 The WASP-Tool in practice Biowaste Paper Metals Plastics Glass Other The sum of the categories should sum up to 100. The WASP-Tool is hosted in the project s website: wasptool.hua.gr Enter the name of the country, prefecture and municipality Enter the population and waste generation per capita The breakdown of waste is introduced Assignment of the relative weight for each indicator

21 Conclusions WASP-Tool is developed and implemented via identification and evaluation of different waste prevention activities using Life-Cycle thinking for municipalities. Testing the utilisation of a waste prevention support tool in two countries that share many similarities and characteristics of the Mediterranean space, but still posing many differences, is of particular interest. The toolkit can help produce or update a waste prevention strategy in other Mediterranean countries that face similar problems with their waste management.
