“…For the environmental assessment, the paper uses the concept of Material Footprint Indicators: The raw material use is measured by the Material Footprint [5]. The Material Footprint is an indicator based on the concept Material Input per Service Unit (MIPS), also known as Ecological Backpack.…”

The circular economy approach implies significant different potentials, hurdles and barriers according to different industries and products -so far without systematically taking into account differences between sectors. This paper takes the example of the carpet industry that due to its so far low material recycling rates and resource intensity is highly interesting with regard to further promote and strengthen circular economy activities and outlining barriers as well as approaches for overcoming these. Focussing on the EU market, it analyses current material flows including end-of-life (EoL) treatment patterns as well as existing policy frameworks. In this paper three scenarios of carpet production are compared with regard to the material footprints: a nylon carpet with 100% virgin fibres, another nylon carpet with 50% virgin and 50% recycled fibres and a third carpet made from 100% recycled fibres. Considering the economic and environmental potentials of circular alternatives, the paper argues that focussing on increased recycling rates alone will not be beneficial but could rather lead to higher environmental burdens, if no significant design changes take place. Such changes need furthermore be accompanied by altered policy frameworks in order to make a circular carpet industry a viable option. These conclusions are based on analyses of the regulatory framework and treatment patterns and an environmental impact analysis of primary and secondary carpets.

“…For material footprint the material-input-per-service (MIPS) is chosen (see also [29,[34][35][36]). The necessary impact factors (raw material extraction and unused extraction from nature) are mostly based on Wiesen et al (2014) [37].…”

“…Functioning as a proxy for a much more complex issue, both impact categories are strongly linked to the EEIs. A more detailed description of advantages and limitations of material flow accounting (MFA) and similar methods (e.g., primary energy demand) can be found in the literature [29][30][31][32].…”

Abstract:The long-term transition towards a low-carbon transport sector is a key strategy in Europe. This includes the replacement of fossil fuels, modal shifts towards public transport as well as higher energy efficiency in the transport sector overall. While these energy savings are likely to reduce the direct greenhouse gas emissions of transport, they also require the production of new and different vehicles. This study analyses in detail whether final energy savings in the transport sector also induce savings for material resources from nature if the production of future vehicles is considered. The results for 28 member states in 2030 indicate that energy efficiency in the transport sector leads to lower carbon emissions as well as resource use savings. However, energy-efficient transport sectors can have a significant impact on the demand for metals in Europe. An additional annual demand for 28.4 Mt of metal ores was calculated from the personal transport sector in 2030 alone. The additional metal ores from semiprecious metals (e.g., copper) amount to 12.0 Mt, from precious metals (e.g., gold) to 9.1 Mt and from other metals (e.g., lithium) to 11.7 Mt, with small savings for ferrous metal ores (−4.6 Mt).

“…Within a context of growing global consumption of goods and services, the current level of resource extraction is unsustainable [1,2]. As physical bounds of the planet are finite, the increasing need for resources leads to environmental and social concerns such as climate change, human health, land use, pollution and water scarcity.…”

Prospective Analysis of Life-Cycle Indicators through Endogenous Integration into a National Power Generation Model

et al. 2016

Abstract:Given the increasing importance of sustainability aspects in national energy plans, this article deals with the prospective analysis of life-cycle indicators of the power generation sector through the case study of Spain. A technology-rich, optimisation-based model for power generation in Spain is developed and provided with endogenous life-cycle indicators (climate change, resources, and human health) to assess their evolution to 2050. Prospective performance indicators are analysed under two energy scenarios: a business-as-usual one, and an alternative scenario favouring the role of carbon dioxide capture in the electricity production mix by 2050. Life-cycle impacts are found to decrease substantially when existing fossil technologies disappear in the mix (especially coal thermal power plants). In the long term, the relatively high presence of natural gas arises as the main source of impact. When the installation of new fossil options without CO 2 capture is forbidden by 2030, both renewable technologies and-to a lesser extent-fossil technologies with CO 2 capture are found to increase their contribution to electricity production. The endogenous integration of life-cycle indicators into energy models proves to boost the usefulness of both life cycle assessment and energy systems modelling in order to support decision-and policy-making.
