Energy recovery from urea in decentralised wastewater streams
Asiain-Mira R., Zamora P., Rogalla F., Monsalvo V., (Corresponding) Torrente-Murciano L.
Topic:
Water, energy and/or food nexus
This work presents the design of a new process that enables energy recovery from wastewater, based on the selective adsorption of urea from urine and its subsequent decomposition into hydrogen.
Removal of nitrogen compounds is at the core of wastewater treatment, as their uncontrolled discharge...Read more

An overview of the plastic waste and recycling status in Qatar
(Corresponding) Hahladakis (Chachladakis) J.
Topic:
Solid waste management
The State of Qatar has recently launched its national vision (QNV2030) underlining, therein, its full commitment to retain harmony between the main three pillars of sustainable development: economic growth, social development and environmental management. However, rapid development and "mega...Read more
Exploring the effects of static magnetic fields for the enhanced valorization of sewage sludge by anaerobic digestion
(Corresponding) Di Costanzo N., Cesaro A., Di Capua F., Mascolo M., Esposito G.
Topic:
Waste management
Anaerobic digestion (AD) is an interesting and sustainable option to handle sewage sludge (SS), as it generates a methane-rich biogas and a digestate with potential fertilizing properties. Several strategies have been proposed to enhance AD performances and the valorization of SS. Among these, the...Read more

Improving the homogeneity of a sewage sludge-based phosphorus fertilizer by Monte Carlo simulation of the production chain
Vogt S., (Corresponding) Brueck F., Schnabel K., Weigand H.
Topic:
Solid waste management
Sewage sludge mono-incineration with subsequent phosphorus (P) recovery from the ash is becoming increasingly important in many European countries. Plant operators are facing the challenge to produce a homogeneous P output which needs to conform to fertilizer standards (including trace elements...Read more
Nutrients recovery from liquid anaerobic digestate by combining nanofiltration and struvite precipitation - The case of dairy effluents valorization
Tsaridou C., (Corresponding) Karanasiou A., Sioutopoulos D., Plakas K., Tzioumaklis C., Patsikas N., Gliaos P., Karabelas A.
Topic:
Sustainable supply of raw materials
Results are reported herein of a study aiming to develop an integrated process for valorizing liquid digestate (LD) from an industrial anaerobic digestion (AD) plant treating dairy-processing effluents. The investigated approach involves LD treatment by nanofiltration (NF) membranes, at pilot-scale...Read more
Oxic-Settling-Anaerobic under intermittent aeration: effect on system performance, sludge minimization and greenhouse gas emissions
Dı Trapanı D., Cosenza A., (Corresponding) Bosco Mofatto P., Mannina G.
Topic:
Wastewater treatment
The paper presents the results of an experimental study carried out on a pilot scale activated sludge system operated under intermittent aeration and fed with real wastewater at the Water Resource Recovery Facility of Palermo University (Italy). The experimental campaign was divided into two...Read more
Coffee ground biosorbent for nitrite and nitrate recovery and soil nutrient
Ying T., (Corresponding) Sethupathi S., Hon L.
Topic:
Recycling of materials to new products
Nitrate (NO3-) and nitrite (NO2-) are two forms of nitrogen that contribute to the occurrence of eutrophication if found in excess concentrations. Conversely, nitrogen is one of the major macronutrients required for healthy plant growth. The purpose of this work is to evaluate the recovery of NO3-...Read more
Low molecular weight polymers in aquatic environments as pollutants of emerging concerns: recovery, quantification and microstructure
(Corresponding) Giannattasio A., Iuliano ., Oliva G., Giaquinto D., Capacchione C., Korshin G., Barcelo D., Naddeo V., Belgiorno V., Buonerba A., Grassi A.
Topic:
Citizen Science in Environmental Monitoring
Microplastics and, more in general, synthetic polymer debrides of anthropic origin are accumulating in the environment, in particular in marine water and sediments, with risks associated for aquatic organisms and humans not well wholly understood. In this contribution it is reported a new method...Read more
