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

Cynara cardunculus as a sustainable solution for phytoremediation of antimony contaminated areas.

Tseliou E., (Corresponding) Mystrioti C., Xenidis A., Papassiopi N.

Topic:

7. ENVIRONMENTAL POLLUTION

Cynara cardunculus (cardoon) is a promising bioenergy crop, well-adapted to the Mediterranean climate. Recent studies suggest its potential for phytoremediation of soils contaminated with heavy metals such as Cd, Ni, and As. This study explores the potential of cardoon for remediating soils...Read more
