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

Strategies for the improvement of VFAs recovery in the nanofiltration process within the circular economy framework

Pervez M., Uwineza C., Sapmaz T., Mahboubi A., Hasan ., Cai Y., Zarra T., Belgiorno V., Taherzadeh ., (Corresponding) Naddeo V.
Topic: 
Food waste
Over the past decades, the anaerobic digestion (AD) process has been employed as a potential medium to produce valuable resources from the waste-based feedstock. Moreover, the use of AD technology can generate not only resources, but it also creates an avenue for useful chemicals recovery to...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

Prior electro-mechanical separation to improve metal recovery from ceramic-rich electronic waste using bioleaching

(Corresponding) Baniasadi M., Ray D., Graves J., Bolton R., Renshaw D., (Corresponding) Farnaud S.
Topic: 
Solid waste management
PCBs, as one of the most valuable streams of e-waste, are a considerable source of precious metals, but also contain considerable amounts of plastic and ceramic. These non-metallic fractions interfere with and can inhibit the efficiency of metal recovery, particularly for precious and rare earth...Read more

Condensate originating from household food waste as a substrate for Microbial Fuel Cells

Kamperidis T., Pandis P., Vlachaki E., (Corresponding) Tremouli A., Lyberatos G.
Topic: 
Environmental biotechnology and bioenergy
A microbial fuel cell (MFC) is a bioreactor that converts the chemical energy of the bonds of organic compounds to electrical energy, through the catalytic reactions of microorganisms. Under anaerobic conditions various substrates have been examined using MFC technology. This study examines the...Read more

Can the seasonal variability affect the BMP of fruit and vegetable waste?

(Corresponding) Scotto di Perta E., Lamboglia R., Cesaro A., Frunzo L., Esposito G., Papirio S.
Topic: 
Food waste
Fruit and vegetable waste (FVW), largely produced in open markets, is characterized by highly putrescible materials, thus being a proper substrate for anaerobic digestion. This study investigated the effect of the seasonal variation of FVW, on the biochemical methane potential (BMP). To this end,...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 study of alkali activated slag cement concretes with carbonate and silicate activators.

Sanam I., (Corresponding) Mavroulidou M.
Topic: 
Environmental management and policies
Alkali-activated cements are increasingly gaining interest as viable alternatives to Portland cement, because they are considerably reducing CO2 emissions compared to traditional Portland cements while maintaining or exceeding performance requirements commonly specified for construction...Read more
