Planar Mixing Tool for Enhanced Performance of Covered Anaerobic Pond Systems
(Corresponding) Brück F., Velten H., Pingsmann M., Meyer D., Weigand H., Linnenberg C., Theilen U.
Topic:
New solutions for a better and sustainable agriculture
Pond systems are the simplest and most widespread technology for the treatment of high-strength wastewater containing biodegradable suspended solids. When covered, they offer significant advantages such as odour control, intensification of the decomposition process, and the potential to capture...Read more
The role of biomass and biowaste in the green energy transition of islands and an introduction to the μgas-to-grid concept
(Corresponding) Vakalis S., Fountoulakis M.
Topic:
Energy technologies and sustainability
The green transition of the energy sector in islands has always been a challenging task. The connectivity of islands with the (mainland) central grid can be problematic, especially when the distance is significant. In such cases, isolated electrical grids need to be developed on the islands, and...Read more

A review on the potential use of flammable gases from sewage systems as a source of energy
(Corresponding) Ghaffari M., Paurine A., Ali S., Mavroulidou M.
Topic:
Energy technologies and sustainability
The demand for natural resources has increased exponentially due to the consistent growth of the global population and urbanization. This has resulted to considerable environmental challenges that are potentially affecting the global sustainable development goals. Therefore, it is important to...Read more
Feasibility of coupling hydrogen and methane production during sewage sludge digestion
Ellacuriaga M., Aguilar-Pesantes A., (Corresponding) Gómez X.
Topic:
Energy technologies and sustainability
Anaerobic digestion is a technology widely used for the stabilisation of sewage sludge in wastewater treatment plants (WWTP). This technology presents several advantages such as the production of energy and the use of this energy to cover the demand of the treatment plant. However, sludge digestion...Read more

Impact of Fatty Waste on Anaerobic Digestion of Sewage Sludge at a Municipal Wastewater Treatment Plant - A Case Study
(Corresponding) Umiejewska K., Retman M., Lech P.
Topic:
Waste-to-energy
Anaerobic digestion is a common method for utilization of sewage sludge at large-scale wastewater treatment plants. This process generates biogas, which is a source of renewable energy. Intensification of biogas production can be achieved, for example, through co-digestion, with fatty waste...Read more

Investigating the Performance of Anaerobic Co-Digestion of Primary Sludge and Acid Whey Using a Twin Pilot Scale System
(Corresponding) Gkoumas F., Tzivelou E., Gravanis Z., Mamais D., Malamis S., Noutsopoulos C.
Topic:
Waste-to-energy
Anaerobic Digestion (AD) has proven to be an effective method for transforming organic waste into biogas, a renewable energy source that can play a crucial role in reducing our dependence on finite fossil fuels. Despite its widespread use, mono-digestion, where a single substrate is utilized, is...Read more
Biogas Desulfurization by Pelletized Biomass Ash in a Fixed Bed Arrangement
(Corresponding) Lapp F., Brück F., Liebich T., Lang M., Theilen U., Weigand H.
Topic:
Gas emissions control and utilization
The removal of H2S is a prerequisite to the energetic valorization of biogas in combined heat and power (CHP) plants. Conventionally, the final step in desul-furization involves filtration over granular activated carbon (GAC). Rising market prices for GAC have fostered research on alternative...Read more
Direct upgrading of biogas produced by anaerobic digestion: preliminary results at laboratory scale
Bonaccorsi L., Fazzino F., Fotia A., Malara A., Pedullà A., (Corresponding) Calabrò P.
Topic:
Environmental biotechnology and bioenergy
The present study investigated, at laboratory scale, the possibility of achieving biogas upgrading with a single step of treatment, namely without involving any pre- or post-treatment or multiple stage recirculation. In this respect, three commercial molecular sieves (i.e., Honeywell 13X, 4A, and...Read more
