A review of technologies for closing the P loop in agriculture runoff: contributing to the transition towards a circular economy
(2022-04)
Article
Accés obertPhosphorus (P) scarcity and the environmental hazards posed by P discharges have triggered the development of technologies for P sequestration and removal from waste streams. Agriculture runoff usually has P concentrations ... -
A robust multicriteria analysis for the post-treatment of digestate from low-tech digesters. Boosting the circular bioeconomy of small-scale farms in Colombia
(2022-09)
Article
Accés obertLow-tech digesters are sustainable technologies to produce a clean fuel (biogas), which can be used for cooking and heating. Moreover, the degradation of organic waste in the digester also produces a liquid effluent ... -
Accumulation of polyhydroxybutyrate in Synechocystis sp. isolated from wastewaters: effect of salinity, light, and P content in the biomass
(Elsevier, 2022-06)
Article
Accés restringit per política de l'editorialCyanobacteria are of particular interest as they can produce Polyhydroxybutyrate (PHB), which is a promising alternative to oil-based plastics, using only inorganic carbon and solar light. However, new strategies should ... -
Adaptación de biodigestores tubulares de plástico a climas fríos
(2009)
Article
Accés obertFarmers in the Andean Plateau strongly demand for household biodigesters due to the lack of clean fuels and agricultural fertilizers, and the abundance of livestock residues. The diffusion of rural biodigesters in cold ... -
Advanced biokinetic and hydrodynamic modelling to support and optimize the design of full-scale high rate algal ponds
(Elsevier, 2022-01)
Article
Accés obertHigh rate algal ponds (HRAP) are known for their suitability to treat wastewater and to produce microalgal biomass, which can be converted into bioproducts. However, full-scale application of HRAP is still limited to few ... -
Advances in clog state monitoring for use in automated reed bed installations
(2014-01)
Article
Accés obertConstructed wetlands are a popular form of waste-water treatment that have proliferated across Europe and the rest of the world in recent years as an environmentally conscious form of waste water treatment. The ability to ... -
