Strategies for the improvement of VFAs recovery in the nanofiltration process within the circular economy framework
Pervez M., Uwineza C., Sapmaz T., Mahboubi A., Hasan ., Cai Y., Zarra T., Belgiorno V., Taherzadeh ., (Corresponding) Naddeo V.
Topic:
Food waste
Over the past decades, the anaerobic digestion (AD) process has been employed as a potential medium to produce valuable resources from the waste-based feedstock. Moreover, the use of AD technology can generate not only resources, but it also creates an avenue for useful chemicals recovery to...Read more
An overview of pressure-driven membrane technologies for a sustainable recovery of volatile fatty acids (VFAs)
Pervez M., Mahboubi A., Hasan S., Cai Y., Zarra T., Belgiorno V., Taherzadeh M., (Corresponding) Naddeo V.
Topic:
Food waste
Currently, petroleum-based volatile fatty acids (VFAs) sources are not acceptable towards sustainable development goals (SDG); therefore, biobased-derived VFAs are of interest. Anaerobic digestion has been identified as a useful technology for the production of biobased VFAs from organic waste...Read more
Optimized use of biogenic waste streams through the combined production of bio-based products and bio-hydrogen
(Corresponding) Küppers M., Brunstermann R., Widmann R.
Topic:
Biowaste
Since 2015, there has been a legal obligation in Germany for the districts and cities to collect biowastes separately, which are then treated in a composting plant or fermentation plant. However, in both aerobic and anaerobic biowaste treatment, a large part of the carbon contained in the waste is...Read more
Hydrogen and organic acids production from mesophilic and thermophilic dark fermentation of sugarcane vinasse without buffers
(Corresponding) Ribeiro J., Mota T., Oliveira V., Zaiat M.
Topic:
Wastewater treatment
The main objective of this study was to evaluate the valorization of vinasse dark fermentation (DF) through bioH2 and value-added metabolites production without buffers in two similar Upflow Anaerobic Sludge Blanket (UASB) reactors under mesophilic (U30) and thermophilic (U55) conditions. An...Read more

Enrichment of mesophilic syngas-converting consortia for methane production
García S., Muñoz R., (Corresponding) Lebrero R.
Topic:
Environmental biotechnology and bioenergy
The use of waste biomass as raw material for syngas production has emerged as a sustainable and cost-effective alternative to the conventional gasifiable feedstock. In addition, syngas bioconversion into value-added compounds could be an interesting approach for carbon fixation and syngas...Read more
Valorization of poultry manure extract enriched with sodium acetate in mixotrophic cultivation of Auxenochlorella protothecoides
Langousi I., Markou G., (Corresponding) Arapoglou D.
Topic:
Recycling of materials to new products
Poultry manure (PM) is byproduct of intensive agricultural production and can be used as a low-cost microalgae growth substrate due to its nutrient and protein-rich content. Microalgae are capable to grow rapidly and thrive in different substrates, thus serving as a valuable source of biomass. In...Read more
Cometabolic removal of ibuprofen, diclofenac and ciprofloxacin driven by glycerol fermentation in an acidogenic biofilm reactor
(Corresponding) Carneiro R., Gomes G., Zaiat M., Santos-Neto Á.
Topic:
Emerging pollutants
The presence of pharmaceuticals in wastewater has increasingly become a public health issue globally due to the potential impacts it can cause on the environment and public health. In this study, we sought to analyze the cometabolic effect of glycerol fermentation on the removal of ibuprofen (IBU...Read more
The effects of plant biostimulant and mycorrhiza applications on industrial hemp (Cannabis sativa L.) growth and phytoremediation performance
Karaviti T., Kotoula D., Georgiou P., (Corresponding) Papazoglou E.
Topic:
Soil and groundwater contamination and remediation
Industrial hemp (Cannabis sativa L.) is a fast-growing lignocellulosic crop suitable for the phytoremediation of heavy metals, radionuclides, and organic contaminants on polluted marginal lands. The objective of this study was to evaluate the effects of plant biostimulant and mycorrhiza...Read more
