Document Summary

An introduction to sustainability: environmental, social and personal perspectives (m. mulligan). Developed nations: waste-> resource: since 1990s: new focus on promoting of resource recovery instead of waste disposal, key principle: shift from linear to circular flows. Industrial ecology: study of material and energy flows through industrial systems. >approach to more environmentally efficient use of resources. >notion of ecological flows: three different waste streams, municipal waste, construction waste, hazardous waste. Reality: reduction in production will eventually be needed to reduce volume of global waste streams. Increasing global resource use: problems, depletion of finite resources, deforestation (wood, agricultural production, climate change (energy intensive production processes, local environmental effects, waste (often lack of well-functioning waste collection and treatment systems ) Circular economy smarter product use and manufacture: refuse, rethink, reduce. Extend lifespan of product and its part: reuse, repair, refurbish, remanufacture, repurpose useful applications of materials, recycle, recover.
