Cross-border trade: certification schemes for recycling derived organic fertiliser (RDF)
(Corresponding) Bur A., Laub K., Weiler K., Wern B.
Topic:
Agroforestry, forest and agricultural sustainability
The project ReNu2Farm (Nutrient Recycling – from pilot production to farms and fields, funded by the EU Interreg North-West Europe Program) focuses on closing nutrient cycles to substitute mineral fertiliser and to contribute to a sustainable agriculture by supporting demand-oriented application of...Read more

The Circular Economy Shift for Business Models: Creating value from waste in the Peach Canning industry
(Corresponding) Paraskevopoulou C., Vlachos D.
Topic:
Circular economy and industrial symbiosis
With the Circular Economy (CE) concept emerging, the reorganization of the supply chain (SC) and the reengineering of its processes is highlighted. In Greece, industrialized agriculture and more specifically the peach canning industry can be an important factor for the economy within and outside...Read more
Circular Economy and Green Economy: a network analysis
(Corresponding) Sulich A., (Corresponding) Ferasso M., (Corresponding) Sołoducho-Pelc L.
Topic:
Circular economy and industrial symbiosis
Circular Economy and Green Economy are very popular concepts in modern scientific business management literature. Several papers already addressed both concepts as synonymous while others distinguish them differently. Based on this conceptual gap, this paper aims to shed a light on these topics by...Read more

Material flow analysis applied to a waste treatment plant in Lombardy (Italy)
(Corresponding) Castro F., Fabbri M., Vaccari M., Cutaia L.
Topic:
Solid waste management
Material flow analysis (MFA) allows to quantify inputs, outputs and stocks of a system and to communicate results visually. It can be used for calculating process effectiveness, losses and for identifying critical points within a system, being useful for strategically intervening in a corporative...Read more
Novel hybrid technology for the sustainable development of the circular economy in urban agriculture
(Corresponding) Giaquinto D., Senatore V., Oliva G., Nesticò A., Hasan S., Zarra T., Belgiorno V., Naddeo V.
Topic:
Environmental biotechnology and bioenergy
Climate change and environmental pollution are just some of the main challenges to be addressed. A number of actions have been taken, in particular the circular economy has proved to be among the most effective in overcoming the traditional approach of the linear economy. Circular economy means not...Read more
Shipyards and Ship breaking: Opportunities for utilization of steel under the prism of Circular Economy
(Corresponding) Pournara A., Sakkas V.
Topic:
Circular economy and industrial symbiosis
Among the activities that constitute the process of dismantling a ship is the obligation of proper management of hazardous materials. As almost the entire ship can be recycled, reused or even resold, the ship dismantling industry can also be considered a "green" industry. The steel used...Read more
Studies on the CO2 adsorption mechanism of Na-X and Na-Ca-X coal fly ash zeolites
(Corresponding) Boycheva S., Lazarova H., Zgureva D., Popova M.
Topic:
Climate change mitigation and adaptation
Coal fly ash zeolites (CFAZ) of Na-X and Na-Ca-X types were synthesized using as raw materials fly ashes generated by the combustion of lignite from various deposits with low and medium limestone content. It has been found that CFAZs with higher calcium content superior those containing less...Read more
Bioleaching of valuable elements from red mud using autochthonous biomass
(Corresponding) Cozzolino A., Cappai G., Cara S., Milia S., Carucci A.
Topic:
Circular economy and industrial symbiosis
Red mud (RM) is the main residue produced by the alkaline extraction of aluminum from bauxite, and it contains valuable metals (e.g., iron, aluminum, titanium, silicon). Aim of this research was to investigate the biologically induced leaching of valuable elements from RM using autochthonous...Read more

Development of Advanced Electrokinetic Separation for Sulfur-Containing Hot Spring Discharge with High Acidity
Lin Y., Tseng P., Fan C., (Corresponding) Pan S.
Topic:
Water and wastewater reuse
Hot springs at the Beituo district, Taiwan are well-known for containing a significant amount of white or blue sulphur. With strong acidity and high conductivity, the used hot springs water did not meet the effluent water quality standards of the sewerage system. Discharging without appropriate...Read more

CIRC4FooD: An urban food production system inspired by the circular economy
(Corresponding) Tsatsou A., Ioannides C., Noutsopoulos C., Tsimiklis G., Chrisomallos G., Tsiropoulos Z., Mamais D., Malamis S.
Topic:
Spatial environmental planning
The environmental footprint of the current, linear food system is a key challenge that must be faced for a global transition to sustainability. Agricultural practices are drivers of polluting food production, while cities form critical hubs of wasteful food consumption. In this context, urban...Read more
