Sustainable treatment of air pollutants by moving bed biofilm reactor (MBBR) coupled with algae photobioreactor (APBR)

Pahunang R., (Corresponding) Zarra T., Oliva G., Senatore V., Belgiorno V., Ballesteros F., (Corresponding) Naddeo V.

Topic:

Environmental odour, monitoring and control

The presence of high concentrations of VOCs in the atmosphere can lead to negative consequences for humans and the environment. The treatment of these compounds is thus necessary before their release into the atmosphere. In the study, an advanced moving bed biofilm reactor (MBBR) coupled with an...Read more

DETERMINATION OF GREENHOUSE GASES EMISSIONS FROM PMDI PRODUCTS IN GREECE

(Corresponding) Glytsos T., Mammi-Galani E., Chalvatzaki E., Korkontzelou A., Letsios V., Alexandrakis S., Lazaridis M.

Topic:

Climate change mitigation and adaptation

The focus of the current study is on the estimation of greenhouse gases (GHG) emissions from pressurized Metered Dose Inhalers (pMDIs) products in Greece. The emissions are expressed as carbon dioxide equivalent (CO2eq). The total emissions of the pMDIs were estimated at 47.53 kt CO2eq and they...Read more

Water Losses Assessments to support decision making in WSS management

(Corresponding) Pietrucha-Urbanik K., Tchórzewska-Cieślak B.

Topic:

Water policy, management and society

In order to reduce costs related to water supply service, modernization measures should be carried out to water losses. The paper presents an analysis and assessment of water losses carried out based on data provided by a water utility company. The basic indicators of water loss according to the...Read more

(Corresponding) Anani O., John O.

Topic:

Biodibersity conservation

The crab species africanus is a very notable detritivore, feeding on dead organic materials. It makes use of energy from the food and transfers it into the food chain trophic level, contributing to the gross ecosystem efficiency. However, their threat to human consumption and activities is...Read more
