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.

Buildings notably contribute to global environmental negative impacts due to consumption of both embodied energy and natural resources as well as various emissions during their whole life cycle. It is therefore necessary to develop practices to reduce these impacts, mainly by reducing the part of non-renewable resource in material as well as by ensuring the lowest energy consumption possible during their lifetime. New developments in natural fibres and their use in insulating materials can lead to significant improvement in building environmental impact. For this purpose, assessment of environmental performance is needed to support both the design and the production of (new) fibre based insulation solutions. In this context, the Life Cycle in Practice (LCiP) project helps SMEs to reduce the environmental impacts of their products and services across the entire life cycle. Within the frame of this project, Isohemp (BE) hemp concrete block impact is evaluated in a cradle-to-gate LCA. Functional unit is a pallet of hemp concrete blocks ready for shipping. It represents about 1.3 m³ of blocks. Hemp blocks are made by pressing a mix of hemp shives, hydraulic and hydrated limes, and water. Long term carbon storage due to lime carbonation induces a large benefit in Climate Change (CC) category. The balance of the CC indicator for hemp cultivation is also favorable due to carbon dioxide uptake by the photosynthesis occurring during the plant growth. Life Cycle Assessment of hemp concrete blocks ready to ship has also highlights some improvements that can easily be made at the packaging level in order to lower the global environmental impact and increase the sustainability of this insulation material. Data are processed in SimaPro 8 software, with Ecoinvent 3 and ELCD 3 databases, and analyzed with the CML IA method. This method is compliant with the indicators required by EN15804 standard in order to communicate on the environmental performance of Isohemp blocks. [less ▲]

This paper undertakes an environmental evaluation of hybrid vehicles recycling, using industrial data from Comet Traitement SA in Belgium. Three business lines have been modelled and analysed. The first one is relative to the business as usual with a dismantling to recover batteries and engines followed by shredding and post shredding treatments. The second one considers, in addition, the removal of electronic control units (ECU) before shredding followed by same steps than in the first line and the last one is relative to the additional removal of big plastic parts before shredding and business as usual post shredding treatments. Results show non-significant environmental benefits when ECU or large parts of plastics are recovered before shredding. Improvements in terms of environmental benefits are lower than the uncertainty of the results. Indeed, the performing usual process for end-of-life vehicles (ELV) treatment reaches 97% of the ELV which is valorised in terms of metal and energy recoveries. Post shredding treatment units include metals, plastics and energy recovery of residues. Comet business as usual route for ELV valorisation is in accordance with the requirements of the European directive and recommendations for further improvement with dismantling of other parts (ECU or plastics) before shredding are non-relevant in this case.

Buildings notably contribute to global environmental negative impacts due to con-sumption of both embodied energy and natural resources as well as various emissions during their whole life cycle. It is therefore necessary to develop practices to reduce these impacts, mainly by reducing the part of non-renewable resource in material as well as by ensuring the lowest energy consumption possible during their lifetime. For instance, the use of recycled raw materials can lead to significant improvement in building environmental impact. In this context, the Life Cycle in Practice (LCiP) project helps SMEs to reduce the environmental impacts of their products and services across the entire life cycle. Within the frame of this project, Pan-Terre (BE) Acoustix panel impact is evaluated in a cradle-to-gate life cycle assessment (LCA). Evaluation of environmental performance is needed to support both the design and the production of waste based insulation solutions. Manufactured for the last twenty past years, the Acoustix Pan-Terre panel is designed for airborne sound insulation in walls and or floors. This product can only be obtained by mixing in a sensible way two raw materials from cellulose origin, recycled paper and broken shives of flax. Functional unit is 1 m² of panel ready for shipping. Acoustix panels are made by pressing a mix of cellulose from waste paper, flax shives and water. Scraps materials are entirely recycled in the process. Flax cultivation has a favourable impact on the climate change indicator due to carbon dioxide uptake for the photosynthesis occurring during the plant growth. But the drying of the panels is largely contributing to fossil fuel depletion and climate change due to natural gas burners. Life Cycle Assessment of Acoustix sound insulating panels ready to ship highlights some improvements that can be made by optimisation of the drying technology and the (partial) replacement of natural gas burners by alternative fuel burners (such as waste paper and scrap materials). Data are processed in SimaPro 8.1 software, with Ecoinvent 3 and ELCD 3 databases, and analyzed with the CML IA method. This method is compliant with the indicators required by EN15804 standard in order to communicate on the environmental performance of Acoustix panels. [less ▲]

Green Building movement has grown in Jordan for the last 10 year for environmental and financial reasons directly related to energy consumption and cost. Despite the few success stories, green design and green buildings are not yet the norm in the building sector in the country. One main concern for design engineers as well as investors and building owners is the extra cost green building will bring compared to traditional one. This assumption is wrong since a building cost should be analyzed through its life cycle, which not only include design and construction but also operation and maintenance costs as well. Since issuing the Renewable Energy and Energy Efficiency Law No. 13 of 2012, Jordan opened a new era in the RE and EE, a changing point directly related to this law is the ability to sell electricity production to electricity companies and not only being consumers. The building sector is a direct winner if designers and engineers make right decisions. An ambitious but possible goal is to design and build Net Zero Buildings, which are buildings that produce energy as much as they consume. The aim of this paper is to provide real life cost-effective building strategies and design scenarios that will lead to a successful near Zero Energy Building in Jordan. The paper will use a representative residential apartment in the city of Amman (135- 155 m2) as the base case for the study. The design will be upgraded to include main green building strategies recommended for the climatic zone, provide loads for required systems, and test them all against performance and cost. Design scenarios will be tested and refined tell reach the best design formula that will be both functional and cost effective. The paper will provide a list of recommendations for best economically feasible design solutions and system selections that can lead to a near Zero Energy Building in Jordan for residential apartments.

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.
