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

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

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

A comparative assessment of alkali-activated stabilisers including waste materials, for the treatment of swelling-shrinking soils

(Corresponding) Mavroulidou M., Gray C., Gunn M.
Topic: 
Solid waste management
Swelling-shrinking soils (also known as expansive soils) experience very considerable volume changes upon changes in moisture content, thus causing major damages to lightweight structures, pavements, slopes and utilities. To counteract this problem chemical stabilisation of this type of soil with...Read more

Solid Waste Reuse in the Balkan-Mediterranean Region

(Corresponding) Angelis-Dimakis A., Arampatzis G., Alexopoulos A., Pantazopoulos A., Angelis V.
Topic: 
Circular economy and industrial symbiosis
The wide implementation of circular economy and industrial symbiosis in the Balkan and Mediterranean region lags behind most of the other European countries. The economic crisis has had a significant impact to the local businesses, eliminating new investments. Regarding specifically solid waste,...Read more

Design of Road-Side Barriers to Mitigate Air Pollution near Roads

(Corresponding) Huertas J., Aguirre J., Lopez O., Lopez C.
Topic: 
Air pollution
The effects of using solid barriers on the dispersion of air pollutants emitted from the traffic of vehicles on roads located over flat areas were quantified, aiming to identify the geometry that maximizes the mitigation effect of air pollution near the road at the lowest barrier cost. Toward that...Read more

The role of End of Waste Criteria in the Framework of Circular Economy Strategy

(Corresponding) Zorpas A.
Topic: 
General
More than 1.8 billion tonnes of waste are produced each year in Europe. This equals to 3.5 t per person and are mainly produced from commercial activities (e.g. shops, hospitals, restaurants), industry (e.g. clothes manufacturers, pharmaceutical companies), agriculture (e.g. slurry), construction...Read more

A Machine Learning Approach for the prediction of solid fuels consumption in Turkey

Celik N., (Corresponding) Konyalioglu A.
Topic: 
Environmental data analysis and modelling
Solid fuels are very crucial energy sources as most of industries use them for obtaining heat, electricity and light. Furthermore, since solid fuels are scarce sources in Turkey, it is very important to forecast the consumption in order to effectively manage the energy policies and to conduct an...Read more

Evaluation of solid sorbents for acid flue gas emissions treatment

(Corresponding) Ravina M., Cerutti A., Marotta E., Zanetti G., Panepinto D., Ruffino B., Zanetti M.
Topic: 
Air pollution
Removal of acid gases from exhaust emissions of industrial applications (SOx, HCl, HF) still represents a challenge for many sectors, in particular for waste to energy facilities. In dry absorption processes, the solid reagent (typically Ca(OH)2 or NaHCO3) is injected countercurrent to the gas in a...Read more
