“…Several LCA studies have investigated potential reduction in emissions by using alternative fuels including SRF, for instance Georgiopoulou et al (2018), Khan et al (2020), Vermeulen et al (2009), Bourtsalas et al (2018) and Malijonyte et al (2016). However, SRF is typically comprised of a complex mixture of materials, of which, for example, 68% (wt ar) are of biogenic origin such as paper, cardboard, wood and natural textiles (Séverin et al, 2010).…”

“…As the fuel used in cement kilns is commonly fossil oil or coal (lignite), almost any other fuel source is likely to result in at least a small reduction in carbon emissions due to fugitive emissions of methane and high energy used in coal extraction. Several LCA studies have investigated potential reduction in emissions by using alternative fuels including SRF, for instance Georgiopoulou et al (2018) , Khan et al (2020) , Vermeulen et al (2009) , Bourtsalas et al (2018) and Malijonyte et al (2016) .

Scaling up resource recovery of plastics in the emergent circular economy to prevent plastic pollution: Assessment of risks to health and safety in the Global South

Over the coming decades, a large additional mass of plastic waste will become available for recycling, as efforts increase to reduce plastic pollution and facilitate a circular economy. New infrastructure will need to be developed, yet the processes and systems chosen should not result in adverse effects on human health and the environment. Here, we present a rapid review and critical semi-quantitative assessment of the potential risks posed by eight approaches to recovering value during the resource recovery phase from post-consumer plastic packaging waste collected and separated with the purported intention of recycling. The focus is on the Global South, where there are more chances that high risk processes could be run below standards of safe operation. Results indicate that under non-idealised operational conditions, mechanical reprocessing is the least impactful on the environment and therefore most appropriate for implementation in developing countries. Processes known as ‘chemical recycling’ are hard to assess due to lack of real-world process data. Given their lack of maturity and potential for risk to human health and the environment (handling of potentially hazardous substances under pressure and heat), it is unlikely they will make a useful addition to the circular economy in the Global South in the near future. Inevitably, increasing circular economy activity will require expansion towards targeting flexible, multi-material and multilayer products, for which mechanical recycling has well-established limitations. Our comparative risk overview indicates major barriers to changing resource recovery mode from the already dominant mechanical recycling mode towards other nascent or energetic recovery approaches.

“…In general, in most LCA studies, it is assumed that more thorough recycling of end-of-life tires, which will lead to the recovery of more and more individual tire components such as rubber, carbon black, steel, and textiles, will result in a minimum carbon footprint (Dong et al, 2021;Fiksel et al, 2011;Li et al, 2014;Malijonyte et al, 2016). Furthermore, Fig.…”

“…The economic parameters that can potentially be included in the sustainability calculation of the metabolic flux set are, for example, media compound costs, market price of product components, and waste management costs (or negative price of the produced components) [30] , [31] . Environmental impacts can be assessed according to the well-established LCA methodology [32] and media compounds and product components can be characterized by their aquatic acidification potential, aquatic eutrophication potential, aquatic ecotoxicity potential, terrestrial eco-toxicity potential, terrestrial acidification/nutrification potential, abiotic depletion potential, and global warming potential [33] , [34] calculated based on the data available in such databases as Ecoinvent or GaBi and others [35] . The LCA impact categories or other relevant approaches [36] can be used to also assess the societal sustainability via e.g., the human health impacts of the media compounds and product components by their human toxicity potential, ozone depletion potential, photochemical oxidant creation potential, as well as impacts of urban, agricultural, natural land occupation potential, public opinion and social acceptance, and jobs created.…”

Industrial biotechnology represents one of the most innovating and labour-productive industries with an estimated stable economic growth, thus giving space for improvement of the existing and setting up new value chains. In addition, biotechnology has clear environmental advantages over the chemical industry. Still, biotechnology’s environmental contribution is sometimes valued with controversy and societal aspects are frequently ignored. Environmental, economic and societal sustainability of various bioprocesses becomes increasingly important due to the growing understanding about complex and interlinked consequences of different human activities. Neglecting the sustainability issues in the development process of novel solutions may lead to sub-optimal biotechnological production, causing adverse environmental and societal problems proportional to the production volumes. In the paper, sustainable metabolic engineering (SME) concept is proposed to assess and optimize the sustainability of biotechnological production that can be derived from the features of metabolism of the exploited organism. The SME concept is optimization of metabolism where economic, environmental and societal sustainability parameters of all incoming and outgoing fluxes and produced biomass of the applied organisms are considered. The extension of characterising features of strains designed by metabolic engineering methods with sustainability estimation enables ab initio improvement of the biotechnological production design.
