This chapter presents life cycle inventories (LCI) of stainless steel products (cold-rolled coils) with a focus on the challenges associated to the use of this material in the construction domain: roofs, façades, technical equipment, structural components. After an introduction describing recent applications of stainless steel in the construction domain, an overview of the challenges related to the use of this material is presented. In this section, a special attention paid to the Leadership in Environmental and Engineering Design (LEED) developed by the US Green Building Council (USGBC), that was one of the world’s first green building rating system (1990) and most widely used internationally. The most recognized European environmental assessment methods will also be mentioned. Several grades will then be described with regard to their mechanical (resistance and ductility) and physical properties (solar reflectance, thermal emittance) as well as surface finishes available for the construction domain. Afterwards, three grades in the form of cold-rolled coils (grades 304, 316 and 430) will be compared in terms of life-cycle inventory from cradle to gate including the end-of-life treatment. Indeed, since stainless steel is recycled to more than 90% at the end of its life and recyclable and indefinite number of times, the method that will be taken into account is referred as “allocation for scrap inputs and outputs using the closed material loop recycling methodology”. A short description of the reference method will also be provided. Last, depending on the recycling rate and thus net recycling content, several impacts such as the energy demand and CO2 emissions will be compared. The influence of the end-of-life credit method will be underlined and discussed. [less ▲]

This document gives an overview of the challenges and issues related to a sustainable use of steel in the construction sector. After an introduction that concerns the challenges associated to the use of steel as a sustainable material, the principles of a life-cycle analysis are presented. The paper then focuses on the life-cycle inventory data of several products: finished cold-rolled coil, electro-galvanized steel, section rolling and rebar. The data are presented for two (sometimes three) different recycling rates. Indeed, since steel is recycled to more than 85% at the end of its life and recyclable and indefinite number of times, the presented inventory includes allocation for scrap inputs and outputs using the closed material loop recycling methodology developed by the International Iron and Steel Institute (IISI). A description of the method principles is also provided. The influence of the end-of-life credit method will be discussed. Corrosion and subsequently maintenance of steel products will be treated afterwards and a brief comparison of the life-cycle inventory will be provided for electro-galvanized steel and finished steel.

In the context of global change understanding the interactions between plant ecology and plant physiology remains a crucial issue. In this study we aimed at analyzing the vascular characteristics involved in the ecological traits of woody species from the northern Congo Basin. We crosschecked three databases: the botanical inventories (857 spp.) and the database of life history traits (464 spp.) produced during the CoForChange project, and the anatomical database Inside Wood (761 spp. and genera for tropical Africa). A total of 211 shared species was obtained. We performed correspondence analyses between the tangential diameter of the vessel lumina (40-43), the number of vessels per mm² (46-50) and five life history traits: leaf phenology, light requirement, seed dispersal, tree size and wood density. Species were distributed along a gradient from species with numerous small vessels to species with few large vessels. This distribution was correlated to a gradient in leaf phenology and light requirement: from evergreen shade-tolerant species to deciduous non-pioneer and pioneer light-demanding species. Dispersal followed this distribution in a lesser extent: from zoochoria to autochoria via anemochoria. Finally, a gradient in size was observed, from small shrubs to tall trees, as well as a gradient in wood density, from dense to light woods. We conclude that the ecological traits of the African tropical woody species are closely related to their hydraulic functioning. The strategies adopted by plants regarding light and water availability can thus be deduced from their vascular characteristics. On this basis we anticipate that climate change will foster light-demanding tree species as better competitors than shade-tolerant species, especially as drought stress is concerned. Further research is needed to increase the input of wood anatomy in explaining the life history traits in African tropical species. [less ▲]

We lack a reliable scenario for the formation and evolution of stars and their planetary systems, involving key factors such as magnetic fields and turbulence. We present the case for a mission concept that will clarify these problems and give us a global view of the evolution of combined star and planetary systems. This will be achieved by simultaneously addressing the search for planetary transits in front of a large number of stars, including many nearby stars, the study of their internal structure and evolution via asteroseismology, and that of their magnetic activity, via UV monitoring.

Eradication by culling of infected animals is not economically sustainable in highly infected regions such as Argentina, US or Japan. Partition and confinement on BLV-infected cows is expensive due to duplication of facilities. Finally, several candidate vaccines based on recombinant viral proteins were unsuccessful to protect from challenge. Facing these failures, we propose a novel strategy based on the use of a live-attenuated BLV provirus. The rationale behind this strategy relies on the deletion of genes required to induce pathogenesis leaving those involved in infectivity, resulting in an attenuated mutant with impaired transmissibility. In a first set of experiments, we show that the mutant is infectious and elicits an efficient immune response in sheep (n=3) and in cows (n=9). Lack of spread to uninfected sentinels further supports the safety of the vaccine. Based on these promising results, a validation program in herd (n=105) is ongoing to evaluate the capacity of the candidate vaccine to protect from wild-type BLV infection. The following experiments are carried out: quantification of the proviral loads, assessment of immune response efficiency (antibody titers, CTL response and cytokine profiling), measure of viral expression in vivo (qRT-PCR) and ex vivo (expression of Tax and p24gag) and determination of provirus clonality during infection. This data will be instrumental for understanding the basic mechanisms undergoing during BLV infection and for elaborating of a novel vaccine. [less ▲]

Different control strategies have been implemented worldwide to control BLV infection or eradicate the disease with diverse success. Eradication by culling is not economically sustainable in highly infected regions such as Argentina, US or Japan. Segregation of BLV-infected cattle is expensive due to duplication of facilities. Finally, several candidate vaccines based on recombinant viral proteins were unsuccessful to protect from challenge. Therefore, here we propose a novel strategy aimed to decrease seroprevalence based on the employ of a life-attenuated BLV provirus as a candidate vaccine. The rationale behind this strategy is the deletion of genes required to induce pathogenesis leaving those involved in infectivity, resulting in an attenuated deletant with impaired transmissibility. Preliminary experiments showed that the deletant provirus is infectious and elicits an efficient immune response in sheep (n=3) and in the natural host, bovines (n=9). Lack of spread to sentinels further supports the safety of the vaccine. Based on these promissory results, an ongoing validation program is being performed to evaluate the capacity of the candidate vaccine to protect from wild-type BLV infection in herd conditions (n=105). Infection will be routinely monitored and proviral loads will be determined. The efficiency of the immune response will be evaluated by titration of specific antibodies, cytotoxic lysis efficiency and cytokine profile. Viral expression ex vivo and provirus clonality will be also evaluated. This data will be instrumental for understanding the basic mechanisms undergoing during BLV infection and for elaborating a novel vaccine. We do believe this practical and cost-effective vaccination strategy is the sole economically viable in countries with high prevalence. [less ▲]

The paper deals with the development of a tool used for the life cycle assessment of residential buildings located in three different European towns: Brussels (Belgium), Coimbra (Portugal) and Luleå (Sweden). The basic tool focuses on the structure and the materials of the buildings and permits the evaluation of the Embodied energy, Embodied carbon and yearly energy consumption. For that purpose, a different set of original data is taken into account for each location, in which the monthly temperatures, energy mix, heating and cooling systems are defined. The energy consumption, being for heating space or water, for cooling or for lighting is transformed into CO2 emissions to deduce the Operational carbon as well. The influence of the energy mix can therefore be assessed in the basic tool. As a matter of fact, the heating and cooling systems habitually used in the three countries are also of great importance. The District Heating system, is, for instance, incorporated in the basic tool. The presence of solar water heater or photovoltaic panels is also strongly influencing the operational carbon. After a short literature review on building LCA and the description of the basic tool, the software Pleiades+Comfie combined with Equer is used to achieve the complete LCA for one building using two different load bearing frames. The results of the calculations for Brussels climate are verified against these software results. The dependence of the results to parameters such as climate, energy mix and habits is then discussed in the companion paper. [less ▲]
