Fish waste valorization route: production of biohydrogen and volatile fatty acids under different process conditions

(Corresponding) Arhin S., Esposito G., Cesaro A.

Topic:

2. CIRCULAR ECONOMY AND BIOECONOMY

Acidogenic fermentation with anaerobic microbial consortia is an attractive route for fish waste (FW) valorization towards high-value products, including volatile fatty acids (VFAs) and biohydrogen (H2). Nonetheless, literature on the influence of operational parameters on VFAs and H2 production...Read more

Electrospun microbial protein and cellulose acetate nanocomposite fibers for heavy metals-contaminated water remediation

(Corresponding) Marra S., Venezia V., Maraviglia C., Luciani G., Matassa S., Cesaro A., Silvestri B.

Topic:

2. CIRCULAR ECONOMY AND BIOECONOMY

Heavy metal pollution is a major environmental issue, with industrial and agricultural activities increasing metal concentrations in water. Effective treatment methods are crucial, and adsorption is one of the most efficient techniques. This study combines microbial proteins (MPs) from waste...Read more

Valorization of organic biosolids at New York City Water Resource Recovery Facilities

(Corresponding) Ramalingam K., Fillos J., (Corresponding) Halim D., Tam T., (Corresponding) Hoffman J.

Topic:

2. CIRCULAR ECONOMY AND BIOECONOMY

New York City’s 14 Water Resource Recovery Facilities (WRRFs) treat 1.3 billion gallons of wastewater daily, producing 1,400 tons of biosolids. Historically landfilled, these biosolids present an opportunity for resource recovery within a biorefinery framework. This study explores three pathways: (...Read more

Volcanic ash recovery and valorization

(Corresponding) Roccaro P., Vagliasindi F.

Topic:

2. CIRCULAR ECONOMY AND BIOECONOMY

Volcanic ash (VA) from Mt. Etna, frequently deposited in surrounding urban areas due to intense eruptive activity, poses significant environmental, infrastructural, and economic challenges, especially related to cleanup operations and air traffic disruption. Traditionally treated as waste and...Read more

Properties of Thermo-Mechanically and Steam-Treated Recycled Wood Fibers from Post-Consumer Waste and Processing Residues

(Corresponding) Xu C., Alao P., Adamopoulos S.

Topic:

2. CIRCULAR ECONOMY AND BIOECONOMY

Engineered wood products like medium-density fiberboard (MDF) are widely used in furniture and construction due to their low cost and ease of processing, with production steadily increasing along with the waste. This research investigates the characteristics of recycled fibers and compares them to...Read more

Environmental and economic assessment of the reuse of expanded polystyrene (EPS) waste as an aggregate substitute in cement mortar

(Corresponding) Alexopoulos N., Vasileiou E., Lazaridou I., Metaxa Z., Prokopiou V., Filippidis A., Zeimpekis V.

Topic:

2. CIRCULAR ECONOMY AND BIOECONOMY

This study investigates the feasibility of using expanded polystyrene (EPS) waste collected in coastal areas as a partial substitute for sand in cement mortars, without the need for pre-treatment. Two scenarios were evaluated: (i) direct collection from polluted coastlines and (ii) recovery from...Read more

From Necessity to Conscious Choice: Second-Hand Clothing and the Environmental Impact of the Fashion Industry

Avdullahi A., (Corresponding) Ademi V.

Topic:

2. CIRCULAR ECONOMY AND BIOECONOMY

This paper takes a closer look at how our clothing choices impact the planet—and how a growing number of people are rethinking those choices. Once seen primarily as a last resort for those with limited means, second-hand clothing is now gaining recognition as a smart, sustainable, and even stylish...Read more
