URBAN RECYCLABILITY: A CREATIVE APPROACH BASED ON FUZZY ASSESSMENT
Abstract
Cities are facing to a new environmental threat, namely the growing quantity and the complexity of waste. Waste generation rates have increased rapidly due to urbanization and industrialization. Per capita waste generation rates in many developing countries have nowadays exceeded one kilogram per day. In most OECD (The Organization for Economic Co-operation and Development) countries, municipal solid waste generation rates are slightly above one-kilogram per capita. Moreover, the population growth and urbanization in developing countries is very high in comparison to OECD countries. Industrial waste generation rates are also very high as most of the industries are primary industries producing raw materials for industrial production. Furthermore, due to improved living standards, improved healthcare and due to globalization, a number of new waste streams have emerged, especially e-waste and hazardous waste. The paper presents a method to assess urban recyclability based on fuzzy logic approach. The basic indicators coming from the technological and economic aspects of the recycling process, quality of recycled materials and environmental of waste are computed into a fuzzy system in order to measure recyclability.
