Circular Economy through Berry Pomace Valorization

(Corresponding) Ispiryan A., Butu A., Jariene E.
Topic: 
2. CIRCULAR ECONOMY AND BIOECONOMY
This investigation delineates the economic aspects associated with the valorization of pomace derived from ten distinct berry varieties within the context of the circular bioeconomy paradigm. Through the implementation of a comprehensive marketing costs and returns (MCR) analysis, this research...Read more

Comparison between different agri-food residual streams as direct source of biosurfactants

(Corresponding) Cruz J., Russo-Martínez N., Vecino X., (Corresponding) Moldes A.
Topic: 
2. CIRCULAR ECONOMY AND BIOECONOMY
In this work various residues were evaluated as direct source of biosurfactants, observing that those coming from the wine, cider, and potato chip industries exhib-ited limited potential as direct sources of biosurfac-tants. Consequently, it should be recommended to evaluate their use as...Read more

Pulp mill sludge-based organomineral fertilizer: performance evaluation on the early growth of Eucalyptus globulus

(Corresponding) Ribeiro H., Carvalho R., Martins T., Fontes L., Carreiro P., Costa e Silva F.
Topic: 
2. CIRCULAR ECONOMY AND BIOECONOMY
This study aimed to evaluate the performance of an innovative pulp mill sludge-based organomineral fertilizer (OrgM) in comparison with a conventional mineral fertilizer (Min). We also assessed its combination with a controlled-release fertilizer (CRF) and potassium sulfate (K). A greenhouse trial...Read more

Low-value production residues from the cork industry: potential raw materials for the growing-media industry?

(Corresponding) Freitas D., Gominho J., Ribeiro H.
Topic: 
2. CIRCULAR ECONOMY AND BIOECONOMY
The cork industry produces several low-value production residues unsuitable for high-end applications due to properties like high density and mineral contamination. This study explores the potential use of two residues: high-density cork granulates (CG) and cork inner bark (CI) as components in...Read more

Industrial Urban Symbiosis: A Solution to Transform Waste into Resources

(Corresponding) Papadopoulou K., Kora E., Antonopoulou G., Ntaikou I., Didachos M., Syriopoulos G., Lyberatos G.
Topic: 
2. CIRCULAR ECONOMY AND BIOECONOMY
The Greek EcoSite, located in Western Achaia, exemplifies the benefits of industrial-urban symbiosis (I-US) through its innovative waste treatment processes and integrated approach. By promoting collaboration between industries and urban areas, the EcoSite optimizes resource use and minimizes waste...Read more
