This volume presents a selection of papers from the WASTES 2015 conference, a platform for scientists and industries from the waste management and recycling sectors from around the world, who shared experiences and knowledge at the meeting. Covering discussions regarding the balance between economic, environmental and social outcomes, the development of innovative techniques, tools and strategies on how wastes can be transformed into good ideas. Improving both the overall environmental performance and the understanding of the industry impact on the environment, as well as the options analysis for its improvement were key objectives of this conference. With this publication it is expected to take the scope of this event beyond the limits of its physical occurrence by providing both scientists, professionals and the general public with an instrument that is the materialization of the main contributions to WASTES 2015.
