Improving the quality and quantity of source-separated household food waste in areas of different socio-economic characteristics: A case study from Lübeck, Germany

(Corresponding) Koerner I., Walk S., Deegener S., Wardle D.
Topic: 
Food waste
A method aiming at improving source-separation performance of household food waste (FW) was investigated in two areas with different socio-economic characteristics in Lübeck, Germany. This included the test of a new FW collection system including the distribution of small collection buckets to each...Read more

Preparation of carbon nanotubes from plastic solid wastes over magnetic nickel ferrite catalysts

Lopes J., Roman F., Santos Silva A., (Corresponding) Diaz de Tuesta J., Lenzi G., (Corresponding) Silva A., (Corresponding) Faria J., Gomes H.
Topic: 
Solid waste management
This work presents the development of magnetic carbon nanotubes (MCNTs) from plastic solid waste (PSW). For this purpose, diverse catalytic nanoparticles based on Fe, Ni and Al were prepared by impregnation of alumina or co-precipitation of Ni, Fe and Al nitrate salts with NH4OH, followed by...Read more

Application of carbon-based catalysts derived from compost on catalytic wet peroxide oxidation of leachate waters from mechanical and biological treatment plant units for municipal solid waste

Batista G., (Corresponding) Roman F., Diaz de Tuesta J., Mambrini R., Gomes H.
Topic: 
Advanced oxidation processes
This work aims at the valorization of compost from mechanical and biological treatment (MBT) units of municipal solid waste by their transformation into carbon-based catalysts for further application in the treatment of MBT leachate waters (chemical oxygen demand (COD) = 60.0 g L-1, total organic...Read more

The Lombard Dairy Industry in the Perspective of Circular Economy: Degree of Application and Improvement Potentials

(Corresponding) Mehner E., Fantin V., Pizzichini D., Vergalli S., Vaccari M.
Topic: 
Circular economy and industrial symbiosis
Circular Economy is an economic concept, aiming at increasing resource efficiency, recirculating resource streams and minimizing waste of an industrial process. Thereby, ideally, environmental impacts can be decreased while the profitability of the considered process is improved. This concept is...Read more

Production and characterization of microalgal biomass from dairy wastewater

Iliopoulou A., Zkeri E., Panara A., Dasenaki M., Aloupi M., Fountoulakis M., Thomaidis N., (Corresponding) Stasinakis A.
Topic: 
Environmental biotechnology and bioenergy
During the last decade, a large scientific effort has been directed towards the cultivation of microalgae in dairy wastewater. Among different microalgal species, Chlorella sorokiniana is a small, fast-growing, robust microalgae that can be grown under mixotrophic conditions. In the current study,...Read more

Increasing the recovery of automobile shredder residue (ASR) through assimilation to a solid recovered fuel (SRF): the results of a feasibility study

(Corresponding) Ruffino B., Minardi M., Guglielmino M., Bonino F., Zanetti M.
Topic: 
Energy technologies and sustainability
This study analyzes the possibility of assimilating some fractions extracted from the shredder light fraction (SLF) to a solid recovered fuel (SRF). Italian Ministerial Decree D.M. 22/2013 fixes the criteria for the assimilation in the compliance of three parameters (heating value and chlorine and...Read more

Biobased Lubricants within a Circular Economy Concept: Utilization of Spent Coffee Grounds as an Alternative Sustainable Feedstock

(Corresponding) Dodos G., Deligiannis A., Karonis D., Zannikos F.
Topic: 
Circular economy and industrial symbiosis
The economy is gradually transitioning to a circular model that extends resources, reduces waste and requires a great deal of creative thinking. Both established and emerging global economies view waste as a bioresource for our next generation energy, chemicals, or platform molecules and materials...Read more

Designing sustainable processes for the valorization of industrial and environmental waste streams towards industrializable polyhydroxyalkanoates

(Corresponding) Ntaikou I., Antonopoulou G., Kokkinopoulou I., Ladakis D., Tragoulias K., Zhang Y., Yan Q., Nan J., Pissaridi K., Spiliotis V., Ladikos D., Moutsatsou P., Koutinas A., Lyberatos G.
Topic: 
Bioplastics
In the present study different environmental and industrial waste streams are assessed as feedstock for the production of bioplastics adequate to be used for food packaging applications or for the formation of fully biodegradable garbage bags. For the production of bioplastics i.e...Read more
