Study of the Airflow Around the Occupants in a Virtual Chamber Equipped with Impingement Ventilation System

(Corresponding) Conceição E., Conceição M., Lúcio M., Gomes J., Ramos A., Awbi H.

Topic:

Environmental data analysis and modelling

The study of the airflow around the occupants in a virtual chamber equipped with impingement ventilation system is made.

Review of the IPCC landfill gas emissions model

(Corresponding) Hutton B.

Topic:

Climate change mitigation and adaptation

Almost all developed nations have agreed to report their annual greenhouse gas (GHG) emissions, under the UN Framework Climate Change Convention of 1997. But only a few directly measure their landfill gas emissions. Most use the Intergovernmental Panel on Climate Change (IPCC) landfill gas model...Read more

CO2 absorption into 4-diethylamino-2-butanol solution in a membrane contactor under wetting or non-wetting conditions

Li L., Pan Z., Baena-Moreno F., Borhani T., (Corresponding) Zhang Z.

Topic:

Gas emissions control and utilization

Natural gas produces a large amount of carbon emissions in the process of mining and processing, on the one hand from the energy use of processing facilities, on the other hand from the way that natural gas is extracted. The adoption of appropriate carbon capture technology is of urgency. The...Read more

AliCy as Extractant to Remove Iron from Copper-Free Extreme AMD for Further Extraction of Zinc

Nobahar A., Melka A., Neves L., Carlier J., (Corresponding) Costa M.

Topic:

Wastewater treatment

A previous work showed that copper can be specifically extracted from acid mine drainage (AMD) classified as high-acid and extreme-metals (pH 1.19, ~63 g/L Fe, ~6.5 g/L Al, ~5.3 g/L Cu, ~1.9 g/L Zn and ~0.1 g/L Mn), using 30% (v/v) Acorga M5640 in Shell GTL (a kerosene like solvent) as extractant...Read more

Advanced Screening Methodologies for the Comprehensive Monitoring of Intentionally & Non-Intentionally Added Substances in Next Generation Food Contact Materials

(Corresponding) Kanakaki C., Mermingi E., Nikolaos T.

Topic:

Bioplastics

The increasing importance of sustainability promotes the development of food contact materials (FCMs) that are safe for the consumers and environmentally friendly. The progressive replacement of ‘‘conventional’’ plastic materials with recycled plastics as well as bio-based and biodegradable...Read more

Air pollution assessment for regulatory purposes: a CFD approach design

(Corresponding) Antuña Yudego E., Fernández Pacheco V., Suárez López M., Álvarez Álvarez E., Carús Candás J.

Topic:

Air pollution

In a context of atmospheric pollution levels on the rise, there is a growing interest in the use of pollutant dispersion tools, especially for regulatory purposes involving industrial activities. Environmental organizations from different countries legislate and encourage the use of different types...Read more

Evaluation of atmospheric pollutants dispersion using CFD numerical models

Fernández Pacheco V., (Corresponding) Antuña Yudego E., Suárez López M., Carús Candás J., Álvarez Álvarez E.

Topic:

Air pollution

This paper describes the approach of studying air pollution by using Computational Fluid Dynamics (CFD) models. It also includes a report of a series of investigations performed in order to illustrate the potential of such models with the aim to give a solution to the dispersion to resolve the...Read more

Designing sustainable processes for the valorization of industrial and environmental waste streams towards industrializable polyhydroxyalkanoates

(Corresponding) Ntaikou I., Antonopoulou G., Kokkinopoulou I., Ladakis D., Tragoulias K., Zhang Y., Yan Q., Nan J., Pissaridi K., Spiliotis V., Ladikos D., Moutsatsou P., Koutinas A., Lyberatos G.

Topic:

Bioplastics

In the present study different environmental and industrial waste streams are assessed as feedstock for the production of bioplastics adequate to be used for food packaging applications or for the formation of fully biodegradable garbage bags. For the production of bioplastics i.e...Read more

Calculating Carbon Footprint in ports through a new Standard Tool: case study applications

Azarkamand S., Ferré G., (Corresponding) Darbra R.

Topic:

Environmental impact of maritime transport

One of the main environmental problems in ports is Climate Change and its consequences. Since 1979, many international organizations have been working to control Climate Change. A literature review and a practical research were carried out to set up the basis to create a tool. These studies showed...Read more

Topic:

Emerging pollutants

Per- and polyfluoroalkyl substances (PFAS) are a class of emerging substances that have proved to be persistent and highly bioaccumulative. They are widely used in industrial and consumer applications and are known for their long-distance migration and toxicity. In this study, 65 recent specimens...Read more
