“…This concept aims to protect products and materials at their highest effective utility while minimising negative impacts (Akanbi et al, 2018). In a sustainable society, the recovery of materials and energy by following circular economy is a challenging task (Kirchherr et al, 2017), (Hoogmartens et al, 2018).…”

The rapid utilization of carbon fibre reinforced composite (CFRC) and glass fibre reinforced composite (GFRC) in main sectors, such as automobile, aerospace, wind turbines, boats and sport parts, has gained much attention because of its high strength, light weight and impressive mechanical properties. Currently, the increasing amount and handling of composite waste at their end-of-life (EoL) has a negative impact on resources conservation and the environment. Pyrolysis, a two-step process, appeared as most viable process to recover not only valuable materials but also produce fuel and chemicals. However, the testing facilities and optimized operation of composite waste in pyrolysis processes to produce materials with low energy consumption and acceptable mechanical properties are still under development and discussion before commercialization. The aim of this article is to review the studies on CFRC/GFRC recycling via pyrolysis processes and highlight their technical challenges and re-use possibilities in high performance composites. The forthcoming commercialization challenges and respective market potential to recyclates using the pyrolysis process will be addressed. This study will also introduce the strong connection between recycling and re-usability of fibres which would help to explain the concept of circular economy and cradle-to-cradle approach. Finally, based on updated studies and critical analysis, research gaps in the recycling treatments of fibrous composite waste using pyrolysis processes are discussed with recommendations.

“…In France in 2020, Citeo (agency organizing REP for packaging industries) fixes a baseline level for eco-contributions of 16,53 ct€/kg for paper and cardboard, and 28,88 ct€/kg for light PET (colourless). 20 Note that almost 80% of these amounts are redistributed for the recycling sector (collecting, sorting and resource production), thus covering the subsidy part of our monetary transfers (Citeo, 2019).…”

“…Perfect substitution is a strong hypothesis here used in several models tackling recycling [4][19] [20]. However it is known that for some raw materials, recycling lowers its quality, sometimes because different materials are mixed in the collecting process, producing a hybrid material with lower properties.…”

We study the recycling opportunity of an industrial sector constrained by climate, resource and waste capacities. A final good is produced from virgin and recycled materials, and its consumption releases both waste and GHG emissions. We identify the optimal trajectories of resources use, mainly depending on the emission rates of each resource and on the relative scarcity of their stocks. Recycling is sometimes an opportunity to reduce the impact of consumption on primary resources and waste but can still affect the environment. We characterize the optimal recycling strategy and we show that, in some cases, the time pace of the recycling rate is inverted U-shaped. Last, we discuss the policy implications of our model by identifying and analyzing the set of optimal tax-subsidy schemes.

“…The interactions between economic growth and material extraction have been explored from a variety of perspectives in the recent literature, including the concepts of eco-efficiency (Zabalza Bribián et al 2011;Yu et al 2018), exergy (Dai et al 2014;Carmona et al 2021), net primary productivity (Du et al 2021), and in applications of Hotelling's model in the circular economy (Hoogmartens et al 2018). All these approaches rely on one principle: economic growth has persistently been driven by an increasing and unsustainable pressure on natural material resources that needs to be considered in modelling applications.…”

Environmental adjustment of the EU27 GDP: an econometric quantitative model

et al. 2022

The use of natural resources as an input to economic growth and the interactions between economic and ecological systems have resulted in an accumulation of environmental externalities. This accumulation can negatively affect future levels of welfare and economic growth. In this paper, such dynamics are assessed and quantified by introducing explicit environmental externality variables in a production function. This is performed in an endogenous growth model where cumulative environmental externalities interact with economic growth. Using efficiency analysis, a dynamic econometric model is estimated showing the significance of a negative influence of past levels of use of natural resources on GDP over a broad range of stochastic frontier analysis estimations. The results are applied to propose an alternative specification to the production function of a modelling tool used by the European Commission for the assessment of climate policies in the European Union. The findings show that observed GDP is overestimated when environmental externalities are not considered.
