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

Performance of metal-free carbonaceous catalysts in the removal of paracetamol by catalytic wet peroxide oxidation

(Corresponding) Santos Silva A., Henrique A., Steldinger H., Diaz de Tuesta J., Gläsel J., Correia Silva J., Etzold B., Gomes H.
Topic: 
Advanced oxidation processes
The performance of metal-free carbonaceous catalysts was evaluated in the removal of paracetamol, chosen as model pharmaceutical micropollutant, by catalytic wet peroxide oxidation (CWPO). The carbon materials were prepared from pentaerythritol tetraacrylate and divinylbenzene copolymer with bis(2-...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

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

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

Exploitation of Crowdsourcing Tools and Earth Observation data: A Systematic Literature Review

(Corresponding) Tsiakou D., Tsimiklis G., Tsiakos V., Karagiannopoulou K., Amditis A.
Topic: 
Environmental data analysis and modelling
Crowdsourcing is a method gaining ever wider use in practice and leverages human intelligence to solve problems in a considerable number of study fields. Howe (Howe 2006) coined the concept defining: “Crowdsourcing represents the act of a company or institution taking a function once performed by...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

Optimum technical operating conditions and treatments for the production of high-purity struvite fertilizer from livestock wastewater.

Kallikazarou N., Koutsokeras L., Constantinide E., Constantinides G., (Corresponding) Antoniou M.
Topic: 
Biowaste
Inadequate treatment of nutrient-rich waste streams originating from human activities such as agriculture, animal breeding, urbanization, and industrialization causes an array of environmental problems. Among them are eutrophication of surface water, nutrients and pathogens leaching into...Read more

Coupling Pb and Zn bioaccessibility with sequential and HNO3 extraction in soil from the industrial area of Volos, Greece

(Corresponding) Kelepertzis E., Botsou F., Sungur A., Sigala E., Daferera O., Kypritidou Z., CHRASTNÝ V., Argyraki A., Komarek M., Skordas K.
Topic: 
Heavy metals in the environment
The urban environment is a complicated system where various anthropogenic sources contribute to the accumulation of metals in soil, leading to potential negative environmental effects. Within this context, we performed single and sequential extractions in contaminated soil from the industrial area...Read more

Nutrient Removal from Stormwater using Australian Native Plants in Constructed Floating Wetland

(Corresponding) Nuruzzaman M., Anwar A., Sarukkalige R.
Topic: 
Water treatment
Stormwater pollution causes excessive nutrient influx to rivers and lakes, which can trigger algal bloom and subsequent damages to the freshwater ecosystem. Constructed Floating Wetland (CFW), a cost-effective technology, uses aquatic plants in a hydroponic system to strip nutrients from stormwater...Read more
