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

Quantification of feedstocks and outputs for a regional Bioeconomy using the AD Biorefinery concept.

(Corresponding) Curry R., Blaine L.
Topic: 
Circular economy and industrial symbiosis
Greenhouse gas emissions (GHG’s) from agriculture in Northern Ireland account for over 27% of regional emissions, as opposed to 7% for the UK overall, leaving the region with challenges in meeting climate abatement targets. The development of a sustainable regional Bioeconomy has been identified as...Read more

Can the seasonal variability affect the BMP of fruit and vegetable waste?

(Corresponding) Scotto di Perta E., Lamboglia R., Cesaro A., Frunzo L., Esposito G., Papirio S.
Topic: 
Food waste
Fruit and vegetable waste (FVW), largely produced in open markets, is characterized by highly putrescible materials, thus being a proper substrate for anaerobic digestion. This study investigated the effect of the seasonal variation of FVW, on the biochemical methane potential (BMP). To this end,...Read more

Anaerobic Digestion of Municipal Wastewater (MWW) in a Periodic Anaerobic Baffled Reactor (PABR)

Zarkaliou A., Kougias C., (Corresponding) Papadopoulou K., Lyberatos G.
Topic: 
Wastewater treatment
The scope of this work is to study the treatment of municipal wastewater in a Periodic Anaerobic Baffled Reactor (PABR). PABR is an innovative, high-rate bioreactor, designed to operate under high organic loadings. Apart from the Hydraulic Retention Time (HRT) an important operational parameter is...Read more

Nutrients recovery from anaerobic digestion effluent for the production of microalgae biomass

(Corresponding) Psachoulia P., Schortsianiti S., Dergiade I., Chatzidoukas C., Samaras P.
Topic: 
Wastewater treatment
The efficient management of anaerobic digestion effluents (ADEs) from biogas plants has raised increasing environmental concerns, as a result of their high content in nutrients, mostly in the form of NH4- and PO4-. Their discharge to farmlands is restricted due to irrigation guidelines, while...Read more

Use of Biochemical Methane Potential (BMP) Assays for predicting biogas production from co-digestion of food waste and compostable bags

Kattamis S., (Corresponding) Maragkaki A., Papastefanakis N., Sampathianakis I., Lolos T., Tsobanidis C., Velonia K., Manios T.
Topic: 
Solid waste management
Biodegradable plastics have been introduced to the market to substitute petro-based plastics to alleviate plastic pollution. Biochemical methane potential tests were carried out on food wastes (FW), with or without pre-treatment, compostable bag and a mixture of food waste and compostable bag (CB)...Read more

Biogas upgrade via ex-situ technologies

Spyridonidis A., Vasiliadou I., (Corresponding) Stamatelatou K.
Topic: 
Environmental biotechnology and bioenergy
The biological upgrade of biogas to biomethane (CH4 > 90%) is a popular emerging technology, since the produced CO2 is not removed but is converted to biomethane using hydrogen (H2). The initial aim of the present study is the acclimatization of a microbial population derived from a typical...Read more

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

APOC technology as an eco-innovative decentralized sanitation system for wastewater treatment and reuse facilities in the rural locality of Bent Saidane-NE Tunisia

(Corresponding) Chaabane S., Ghattassi A., Mensi K., M'hiri F., Plakas K.
Topic: 
Water and wastewater reuse
Decentralized wastewater treatment systems (DEWATS) in rural areas can be a smart alternative that helps communities to strengthen rural sanitation in improving clean water and sanitation management. To address these challenges, AquaCycle project, funded by the European Union under the ENI CBC MED...Read more

The effect of HRT in the successful bioaugmentation of CSTRs working under ammonia toxicity

Tzenos C., Christou M., Kalamaras S., (Corresponding) Kotsopoulos T.
Topic: 
Environmental biotechnology and bioenergy
High levels of ammonia is a common inhibitory factor in anaerobic digestion (AD) resulting in low methane production and unbalance of the process. In the present study, the adjustment of the hydraulic retention time (HRT) and the bioaugmentation process (BP) are investigated to counter the negative...Read more
