IMPROVING INNOVATION CAPACITIES OF PRIVATE AND PUBLIC ACTORS FOR SUSTAINABLE AND PROFITABLE RECYCLING OF LIVESTOCK WASTE
(Corresponding) Antoniou M., Kallikazarou N., Koutsokeras L., Constantinides G., Constantinide E.
Topic:
Water and wastewater reuse
The Mediterranean region is known for its intensive livestock farming, especially for the breeding of pigs and cattle. These activities result in vast amounts of waste that necessitate proper treatment. Inadequate manure treatment can cause eutrophication of surface waters, enrichment of nitrates...Read more
Municipal solid waste management in island communities: existing experience and implementation possibilities for South Aegean Islands
Xanthopoulos P., (Corresponding) Papapostolou C., Kondili E., Stylianopoulou K.
Topic:
Solid waste management
Solid waste management in island communities is triggered by the limitation in the availability of resources, which in combination to the small amounts of wastes produced, renders the selection and sizing of the appropriate methods and infrastructures very challenging. Certain complexity to the...Read more

A detailed characterisation of household food waste and the implications of sorting behaviour on potentials for anaerobic digestion and nutrient recovery
(Corresponding) Walk S., Hausbeck G., Körner I.
Topic:
Food waste
This study investigates household food waste (HH FW) generation in two socio-economically different areas in Lübeck, Germany. The applied waste characterisation protocol provided a detailed insight into the generation and separation behavior of FW collected in the municipal collection system. In...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
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
Keywords:
plastic solid waste, chemical vapour deposition, nanostructured carbons, magnetic nanoparticles, valorization
Removal of gaseous ammonia released from odorous composting leachate employing carbonaceous adsorbents prepared from agro-industrial wastes
PERDIGÃO-LIMA T., Feliciano M., Pereira Wilken A., Gomes H., Shinibekova A., Kalmakhanova M., Massalimova B., (Corresponding) Diaz de Tuesta J.
Topic:
Environmental odour, monitoring and control
Biological and composting processes used in the treatment of municipal solid waste typically are sources of odour pollution (gaseous pollutants include SO2, NH3, H2S and other toxic air pollutants). In this work, the removal of NH3 present in odorous composting leachate was assessed for the first...Read more
Valorisation of polyolefins into magnetic carbon nanotubes: application as catalysts in wet peroxide oxidation of paracetamol
Sanches L., (Corresponding) dos Santos Silva A., Fontana Roman F., Diaz de Tuesta Triviño J., Alves da Silva F., Gomes H.
Topic:
Advanced oxidation processes
This work deals with the application of magnetic carbon nanotubes (MCNTs) in the catalytic wet peroxide oxidation (CWPO) of paracetamol (PCM), a pharmaceutical compound selected as model contaminant of emerging concern (CEC). MCNTs were synthetized by catalytic chemical vapor deposition (CCVD) at...Read more
Transferring the Carbonation of Biomass Bottom Ash from Batch to Continuous Operation
(Corresponding) Schnabel K., Brück F., Pohl S., Weigand H.
Topic:
Mineral carbonation of alkaline waste materials
Biomass incineration residues may be used for CO2 capture and storage by carbonation of waste-borne metal hydroxides. Moist carbonation of these ashes can be performed under mild conditions (ambient pressure and temperature) and accelerated by using a CO2-rich gas. The process requires the wetting...Read more

Carbon nanotubes synthesized from LDPE for application in wet peroxide oxidation of paracetamol
(Corresponding) Roman F., Marim Lopes J., Diaz de Tuesta J., Lenzi G., Tavares da Silva A., Faria J., Gomes H.
Topic:
Advanced oxidation processes
Carbon nanotubes (CNTs) were produced by chemical vapor deposition (CVD) considering low-density polyethylene (LDPE) as a carbon source and as an alternative to upcycle plastic solid waste. The CNTs were synthesized over bimetallic catalysts (Ni and Fe) supported on Al2O3 and purified with H2SO4 to...Read more
Effective separation of waste printed circuit boards using microwave-assisted organic swelling.
Monteiro B., Martelo L., Sousa P., Bastos M., (Corresponding) Soares H.
Topic:
Electric and electronic waste
Nowadays, our lifestyle demands more electronics products, and this rapid development generated an increase in the amount of electronic waste (e-waste). Waste printed circuit boards (WPCBs) are components in all electronic devices and responsible for a high percentage of the total weight of the...Read more
