The potential of oil & gas exporters to contribute to global decarbonization is vastly underappreciated. In the article linked below, I summarize our recent peer-reviewed paper showing how Norway (as an energy exporter) can help Germany (as an energy importer) to decarbonize rapidly, practically, and economically while maintaining attractive profit margins. The key is to develop a local CCS industry (basically just oil & gas extraction in reverse) using the vast pool of relevant local expertise, and export a diversified mix of decarbonized energy products. Electricity and hydrogen can be exported to neighbouring countries, and a wide range of other easily tradeable and storable industrial products (exemplified by steel in our study) can access global markets, reducing risks from uneconomical green technology-forcing policies in neighbouring countries.
Lehigh Technologies has won the Young Global Leaders Award for Circular Economy SME (small to medium-sized enterprise) for The Circulars 2019, the 5th iteration of the award, in Davos at the World Economic Forum on 21 January 2019. Lehigh was recognized for upcycling end-of-life tyre materials into Micronized Rubber Powder (MRP), a sustainable, lower-cost, high performing and customizable feedstock for industrial and consumer markets. MRP is used as an additive in a wide range of consumer and industrial products, like tyres. By improving performance and cost, Lehigh’s business model is said to be closing the loop on tyre production, ensuring sustainability and stability in manufacturing costs for the tyre industry and reducing dependence on oil-based chemicals. According to the company, tyres made with Lehigh’s MRP have better vehicle fuel economy compared to tyres made of less technological rubber powder and have saved a total of over 20 million passenger car tyre equivalents from landfills in more than 10 years. To date, Lehigh’s products have been used to manufacture over 500 million tyres using a circular model. “Consumers, employees, stakeholders and policymakers alike expect companies to lead with purpose around sustainability and are holding them accountable. Inaction or idleness can severely harm competitiveness, with a drop in stakeholder trust costing businesses globally $180 billion in potential revenues,” said Peter Lacy, Senior managing director, Accenture Strategy. “Moving to a circular economy delivers the disruptive change needed to secure a sustainable future, while enabling businesses to unlock innovation and growth. We are proud to recognize the individuals and organizations that are leading the circular movement, creating a thriving global economy.”

Entropy, life-cycle accounting and the circular economy are terms and concepts indicative of how society looks at the world differently than previous generations. As the global population pushes toward 10 billion by the end of this century, thoughtful approaches to sustainability will become ever more essential to policymakers. Yet a coherent narrative remains elusive.
Industrialized countries continue to operate very far from a circular economy. Instead, they rely heavily on a linear economy, where the make-use-dispose product life cycle dominates. A circular economy, by contrast, encourages product reuse and longevity, not disposability and planned obsolescence. Efforts by communities and policymakers to develop circular economies and maintain the viability of natural ecosystems in the United States and other countries take many forms. Several cities around the U.S., including San Antonio, have made it a priority to implement policies aimed at long-term sustainability. For example, in August 2016, the city of San Antonio adopted its SA Tomorrow Sustainability Plan intended to prepare the city for smart, sustainable growth in light of the prospect of an additional million residents by 2040. The plan is a fuller elaboration of past efforts such as Mission Verde and SA2020. For 14 months, the city of San Antonio engaged a broad range of stakeholders in a variety of venues to solicit input and develop the plan. Focus areas include energy, food systems, green buildings, infrastructure, land use, transportation, natural resources, public health and solid waste resources. Cross-cutting themes include air quality, economic vitality, equity, resilience and water resources. On a global basis, some of the most systematic research dealing with sustainability comes from the Stockholm Resilience Centre, which examines planetary boundaries affected by our waste outputs and attempts to gauge those most at risk. The boundaries include stratospheric ozone depletion, which filters out ultraviolet radiation; loss of biosphere integrity, which is necessary for biodiversity; chemical pollution; climate change; ocean acidification; the freshwater cycle; land system change, when forests, grasslands wetlands, coastal fisheries, savannas and other habitats that recycle are converted to municipal, industrial or agricultural use; the nitrogen-phosphorous cycle, or fertilizer runoff; and atmospheric aerosol loading.

Circular economy has gained attention as a key solution for mitigating the increasing generation of solid waste and resource scarcity. As opposed to the linear economy, the concept describes how to develop closed-loop technical and biological cycles by either recycling materials indefinitely with no degradation of their properties (the technical cycle) or returning materials to the natural ecosystem with no harm to the environment (the biological cycle) [1]. Although circular economy practices (such as material recycling) are widely embraced as a sustainability strategy, it is important to consistently assess their net environmental benefits and possible drawbacks [2] and develop methods and indicators that are suitable for assessing circular economy concepts [3]. The term “circular economy” is frequently applied to suggest increased sustainability. However, it tends to focus on an increased quantity of reused and recycled resources and overlook the quality of resource flows re-entering to the product cycle [4]. This can pose a risk of augmenting unwanted recirculation of micro-pollutants [5,6,7,8], if disregarding the material quality, particularly in the transition period from linear to circular systems. In 2015, 241 million tonnes of municipal solid waste were generated in the EU [9]. Of this waste, 40–60% was organic waste [10], representing a great challenge in terms of its management. However, at the same time, organic waste also constitutes a valuable resource as a component in the circular bioeconomy [11,12]. Biowaste-based biorefineries, producing high value products such as enzymes, bioplastic and biofertilizer from the organic fraction of municipal solid waste, is an emerging technology field whose environmental performance should be addressed to ensure a beneficial implementation [12]. This study refers to such circular economy systems related to management of municipal biowaste as circular biowaste management systems (CBWMS). Several decision support tools (DSTs) based on life cycle assessment (LCA) are currently available to assess the sustainability of waste management systems (WMS). These WMS-DSTs are specifically developed to analyse the performance of integrated WMSs from collection, treatment and final disposal. Winkler and Bilitewski [13] and Jain et al. [14] showed large discrepancies in the results obtained when modelling specific scenarios across different WMS-DSTs. Gentil et al. [15] analysed the technical assumptions that caused the difference in the results obtained with various WMS-DST; e.g., time horizon for landfill emissions and calculation of long-term carbon balance when applying biowaste derived compost on soil [15].

VTT Technical Research Centre of Finland has developed what it describes as “an efficient synthetic biology toolbox for industry and research organisations.” The toolbox enables, in an unprecedented way, engineering of a diverse range of yeasts and fungi, says the group. VTT says it comprises DNA parts which can be easily combined to create new biological systems.
The SES (Synthetic Expression System) toolbox seemingly enables expression of genes in yeasts and fungi considerably more efficiently and with better control than has been possible with previous methods. The toolbox is based on DNA components with well-defined functions and the components can be combined “as if they were Lego bricks.” In this way, molecular machines can be built, for example, for improved control of yeast cell performance in industrial bioprocesses for production of polymer precursors, fuels and medical compounds. Because the components of the SES toolbox operate the same way in different species, they can be used to engineer species that have attractive properties, but which have due to lack of engineering tools not been studied or used in biotechnology applications in the past. The SES toolbox is expected to enable development of numerous novel microbial production processes for valorization of various waste materials to higher value compounds. In doing so, the SES toolbox provides important solutions for bio- and circular economy challenges. VTT has written an article about the opportunities opened up by the toolbox, which you can read here. You can also read an article recently published in Nucleic Acids Research here.
