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

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

Citizens’ perceptions towards urban solid waste management system: Case Study of the Municipality of Kozani

(Corresponding) Adamidis T., Latinopoulos D.

Topic:

Waste strategies development

The aim of this study is to investigate, through a survey the perceptions and attitudes of citizens about urban solid waste management system in the Municipality of Kozani. The objective of this survey is to obtain information related to: the actual behavior of citizens, the determining factors...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
