Dynamic heat map as a part of the regional energy transition

Wern B., (Corresponding) Noll F., (Corresponding) Baur F.
Topic: 
Spatial environmental planning
Heat maps show the heat and cold demand of residential, commercial and industrial buildings as well as the waste heat from industry. They combine these two aspects in order to plan new heating/cooling grids. By planning the thermal energy supply in a central way, the efficiency of the energy...Read more

Fine dust impact by wood energy of a structured oil heating replacement in Luxembourg – Possibilities, pathways and impacts

(Corresponding) Wern B., Noll F., Zheng Y.
Topic: 
Energy technologies and sustainability
Heating and cooling needed in 2015 the half of final energy consumption in EU and is the biggest energy sector in EU 28. Often, the energy supply is provided by petroleum products and has to be transformed into low greenhouse gas supply according the agreements of the Paris follow-up-process. This...Read more

UV/H2O2 coupled with adsorption in the decolorization and phytotoxicity effects of dye mixtures

Ortega Tapia A., Alvarez Marroquin C., Cardona Rendón L., Arroyave Quiceno C., (Corresponding) Aristizábal Castrillón A.
Topic: 
Advanced oxidation processes
UV/H2O2 is an effective process for the decolorization of dyes in water; However, after treatment if complete mineralization is not achieved the toxicity of the wastewater usually increases due to the generation of intermediated more toxic than the dye. Thus, a subsequent process to reduce toxicity...Read more

Evaluation phytotoxic effects and decolorization of simulated and real textile wastewaters by UV/H2O2

Quiceno Gómez L., Hernández Gallo M., Cardona Rendón L., Arroyave Quiceno C., (Corresponding) Aristizábal Castrillón A.
Topic: 
Advanced oxidation processes
The discharge of dyes in aquatic ecosystems is of environmental concern due to intense coloration that decrease photosynthetic activity and the possible toxic effects (Hao et al., 2000). Therefore, the development and understanding of processes for the removal of textile dyes in wastewaters, like...Read more

Phase Diagram Modelling of a Multi-component Aqueous Solution of Katwe Salt Lake, Uganda

(Corresponding) Lwanyaga J., Kasedde H., Kirabira B.
Topic: 
Desalination
A methodology is developed to compute the phase diagram of a hexary system and to determine the mineral precipitation sequence upon removal of water. The methodology is applied to construct the phase diagram and precipitation sequence of the system (〖Na〗^+,K^+)(〖Cl〗^-,〖SO〗_4^(2-),〖CO〗_3^(2-)...Read more

Neuro-, geno- and cytotoxicity responses in mussels Anodonta cygnea after six metals mixture treatment

(Corresponding) Butrimavičienė L.
Topic: 
Heavy metals in the environment
Concerning toxicity, bioaccumulation and persistence in the aquatic environment, six metals such as Zn, Cu, Ni, Cr, Pb and Cd are attributed to priority hazardous substances in many countries throughout the world (Water Framework Directive 2008/105/EC; US EPA 2009). In this study, time-dependent...Read more

One-step Synthesis of TiO2/ZnO Nanocomposites by Refluxing Methods for Photochemical Degradation of Humic Acid

(Corresponding) Fadillah G., HIdayat R., (Corresponding) Wahyuningsih S.
Topic: 
Nanomaterials in the environmnents applications and effects
Synthesis of TiO2/ZnO nanocomposites (TZN) through one-step refluxing method for photochemical degradation of humic acid (HA) in aqueous solution has been studied. Titanium isopropoxide (TTIP) and ZnSO4.7H2O were used as a starting material under base solution at 120 oC for 24 hours. TZN materials...Read more

Do Environment-related technologies strengthen the competitiveness of local systems?

De Noni I., Ganzaroli A., (Corresponding) Orsi L.
Topic: 
Enviornmental data analysis and modelling
Environmental innovation is considered one of the key drivers of sustainable development and economic growth. However, we still know very little about the organizational factors underling the development of this category of innovations and their relative competitive effect. In this paper, we focus...Read more
