Batteiger, Alexander ; Rotter, Vera Susanne (2018-02-07)

“Universal access to electricity” is proclaimed as the seventh sustainable development goal (SDG 7) of the United Nations (UN) Sustainable Development Goals list. The achievement of this goal will result in a rapid diffusion of energy technologies that would in turn increase materials stocks, subsequently increase the raw material demand as well as the arising waste flows. This study describes ...

Designing Away Waste: A Comparative Analysis of Urban Reuse and Remanufacture Initiatives

Ordóñez, Isabel ; Rexfelt, Oskar ; Hagy, Shea ; Unkrig, Luisa (2019-04-03)

In order to transform the economy into one that is circular, that recovers most materials through reuse, remanufacturing and recycling, these activities need to grow significantly. Waste management has substantially incorporated recycling as an end-of-life treatment but has still largely failed to incorporate remanufacturing and reuse as possible material recovery routes. This article aims to p...

Marques, Érika Tavares ; Gunkel, Günter ; Sobral, Maria Carmo (2019-06-04)

Due to global warming, a reduction in available water will occur in many watersheds and conflicts concerning water use will take place. This situation is already typical in semi-arid areas, where many reservoirs have been constructed for water storage. Increased energy demands and climate change have led to severe and increasing pressure on aquatic systems. Today, the environmental policies of ...

Data for Fish Stock Assessment Obtained from the CMSY Algorithm for all Global FAO Datasets

Hélias, Arnaud (2019-05-24)

Assessing the state of fish stocks requires the determination of descriptors. They correspond to the absolute and relative (to the carrying capacity of the habitat) fish biomasses in the ecosystem, and the absolute and relative (to the intrinsic growth rate of the population) fishing mortality resulting from catches. This allows, among other things, to compare the catch with the maximum sustain...
