Article
Marine algae are considered promising resources both at present and in the near future. Their availability, together with their molecular structure and properties, increases their applicability in various sectors: food and feed, cosmetics, pharmaceuticals and bioenergy. However, the "bio" qualification does not always imply a lower impact compared...

Proper waste management is a key element in the transition to a sustainable bioeconomy. Population growth and the demand for food and services have led to an ever-increasing production of biotic waste whose disposal in landfills is no longer considered a sustainable option. For this reason, efforts are being made to find an appropriate management s...

Anaerobic treatment of domestic wastewater has been recognized as a feasible technology to reduce energy demand from the valorization of streams with high-organic load. However, there are many factors that influence the environmental and economic profiles of the process, such as the effluent pollutant load, operating temperature and methane emissio...
Chapter
The main challenge in wastewater treatment is changing the perception of wastewater as a waste product to be treated or disposed of, and instead seeing it as a source of energy and other valuable byproducts. This approach is in line with the basic principles of a circular economy, which replaces the ‘end-of-life’ concept with reducing, reusing, rec...
