IWRA is pleased to inform also the release of another new report on “Developing a Global Compendium on Water Quality Guidelines” in collaboration with the World Water Council. This report collects and examines examples of existing recommendations for influent water quality, as applied to various human and ecosystem uses. It provides examples and analysis of existing water quality guidelines. Building on these case studies, the report explores new perspectives, and raises pertinent questions… Mostrar más

IWRA is pleased to inform also the release of another new report on “Developing a Global Compendium on Water Quality Guidelines” in collaboration with the World Water Council. This report collects and examines examples of existing recommendations for influent water quality, as applied to various human and ecosystem uses. It provides examples and analysis of existing water quality guidelines. Building on these case studies, the report explores new perspectives, and raises pertinent questions for future work on the topic, including what an online compendium of such guidelines might look like.

There has been a recent resurgence in research investigating bioenergy production from algal biomass due to the potential environmental benefits in comparison to conventional bioenergy crops and conventional fossil fuels. This life cycle assessment (LCA) considered the energy return and environmental impacts of the cultivation and processing of macroalgae (seaweed) to bioethanol and biogas with a particular focus on specific species (Gracilaria chilensis and Macrocystis pyrifera) and… Mostrar más

There has been a recent resurgence in research investigating bioenergy production from algal biomass due to the potential environmental benefits in comparison to conventional bioenergy crops and conventional fossil fuels. This life cycle assessment (LCA) considered the energy return and environmental impacts of the cultivation and processing of macroalgae (seaweed) to bioethanol and biogas with a particular focus on specific species (Gracilaria chilensis and Macrocystis pyrifera) and cultivation methods (bottom planting and long-line cultivation). The study was based mainly upon data obtained from research conducted in Chile but the results can be applied to other locations where similar cultivation is feasible. Speculative data were also included to test promising data obtained from research. The results suggested that using base case conditions the production of both bioethanol and biogas from bottom planted Gracilaria chilensis was the most sustainable option due to the low input method of cultivation. Using new advances in cultivation and processing methods of long-line cultivated Macrocystis pyrifera however resulted in a much more sustainable source of bioenergy. If these methods can be proven on a large scale, the generation of bioenergy from macroalgae could be highly competitive in of its sustainability compared to alternative feedstocks. Future research should bear in mind that the results of this study should however be considered highly optimistic given the early stage of research. Mostrar menos
