The European Commission’s White Paper on transport (European Commission, 2011) seeks to achieve an efficient and sustainable balance between the various transport modes. Environmental impact studies on intermodality transport show that rail freight transport is the land-based transport that has a higher environmental performance compared to intermodal road-rail and all-road transport (Fries and Hellweg, 2014), especially when electrified railway is used (Spielmann and Scholz, 2005). Life Cycle Assessment (LCA) methodology allows us to model as best as possible the environmental impacts of several pollutants in numerous categories. For other categories such as accident damages, noise impact and land use, new developments have to be performed. For the environmental impact assessment, all life cycle phases of rail freight transport operation, rail infrastructure, and rail equipment are taken into account (Spielmann et al., 2007). [less ▲]

Many drivers exist to persuade EU businesses to embrace the opportunities of the circular economy. However, the challenges faced by companies, particularly among SME’s, in the drive for resource efficiency include access to funding, knowledge and capability, and ability to implement cost-effective technological solutions. It was these factors that inspired the creation of the ReNEW network. ReNEW, ‘Resource innovation Network for European Waste’, is a €5 million project funded by the Interreg IVB North West Europe scheme aiming to increase cooperation between research and business endeavours to create value from waste by optimising novel technologies for extracting materials from waste and their reuse in the supply chain. ReNEW also aims to inform local, national and European policy makers, and to share transnational best practice and improve specific support to meet the innovation needs of the waste sector. Within the frame of this project, several technologies are investigated by partners to improve the valorisation of organic wastes in chemicals such as the production of furfural (C5H4O2 - CAS 98-01-1) by the chemical hydrolysis of contaminated/hazardous woody biomass.

In its Regional Policy Statement for 2009-2014, the Walloon Government (Belgium) undertakes to make Wallonia a model of good governance. Applying this principle in the field of the environment needs to be based on a continuous, objective and strict evaluation of the evolution of the state of environmental components (air, water, soil, biodiversity, etc.), the pressures to which they are subjected, the resultant impacts and the measures taken to improve living conditions within our Region. Within this framework, the General Operational Direction of Agriculture, Natural Resources and Environment (DGARNE) realises reports on the state of the environment in Wallonia, in close collaboration with universities and research centres. A chapter is dedicated to the efficient use of water resources, including a life cycle assessment of anthropic water and rain water harvesting. [less ▲]

This paper focuses on transversal research of the role and influences of rail freight transport, as a part of intermodal transport in Belgium. A SWOT analysis of the current situation is conducted, starting from the actual weak usage of this mode of transport. Five different fields have been identified, impacting the economy and society. Each field indicates critical internal strengths and weaknesses for intermodal rail transportation in Belgium, and identifies possible future developments and setbacks. A Delphi-like approach is used, including a heterogeneous panel of experts, discussing and validating the SWOT results. To prioritize the characteristics, a survey on the different SWOT elements is performed, asking the experts to rate each statement on its influence and likelihood of happening, indicating the level of uncertainty.

This paper undertakes an environmental evaluation of bioethanol production, using wheat cultivated in Belgium. Cultivation steps are modelled using Belgian specific data. Wheat transformation in ethanol relies on industrial data. GHG emissions of the whole life cycle are calculated and compared with the default values given by the European Renewable Energy Directive. Belgian wheat bioethanol achieves a 5% higher GHG reduction than the one mentioned in the European directive but impact repartition is different with a higher importance of cultivation step in our case. Belgian wheat bioethanol complies with the current sustainability criteria but is also able to conform to further ones. Sensitivity analyses are performed on the importance of N fertilizers and associated emissions known as main important parameters. These analyses reveal non negligible variations and then a range of available GHG reduction when using wheat bioethanol. [less ▲]

Boom clay is studied as a potential host rock for underground nuclear waste storage. This experimental work analyzes its response under the convective drying conditions that may be applied in case of contact with the ambient atmosphere (during disposal drilling, for instance) or with gallery ventilation (because of damage in gallery lining). The drying kinetics is first established. In a second phase, the cracking and shrinkage onset and development are focused on, thanks to an X-ray microtomography device. The results show a phase of ideal shrinkage and a phase of shrinkage with desaturation, which are closely related to the kinetics. Cracking and shrinkage progressively develop from the drying surface, up to values representing about 3 and 12% of the cross section area, respectively. [less ▲]

Photocatalysis is a technique used for the purification and decolorization of water. In this work, the photocatalytic decolorization of aqueous solutions of Gentian Violet has been investigated. The photocatalysts used for the study are tin dioxide (SnO2) and zinc oxide (ZnO) doped with sodium and prepared by sol-gel process. Photocatalysts were synthesised by sol-gel process and characterized by several techniques such as X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Brunauer, Emmett and Teller (BET) method and UV-vis Spectroscopy. The results of photocatalytic activity of gentian violet degradation under ultraviolet irradiation, indicated that the synthesised photocatalyst exhibit good photocatalytic performance. [less ▲]
