<\/figure><\/div>\n\n\n\nThe healthcare industry is successful in innovating new treatment paradigms ranging from small molecular to biological therapeutics to personalised medicines.1<\/sup>\u00a0Over the past quarter century, the industry has increasingly adopted green chemistry practices in a continuing effort to improve process efficiency and reduce its environmental footprint.2<\/sup>However, most of these efforts relating to catalysis,3<\/sup>\u00a0process waste metrics,4<\/sup>\u00a0lifecycle assessments,5<\/sup>\u00a0pharmaceuticals in the environment6<\/sup>\u00a0and the phase out of substances of concern7<\/sup>\u00a0mainly mitigate the consequences of pharmaceutical manufacturing. They do not address the underlying issue responsible for global warming, namely that almost all organic chemicals including plastics originate from fossil resources.8,9\u00a0<\/sup><\/p>\n\n\n\n Organic compounds are arguably the foundation of the pharmaceutical industry. All traditional small molecule pharmaceuticals include carbon building blocks \u2013 by definition, organic materials \u2013 which are then transformed via modern synthetic chemistry to assemble the complex and highly variable skeletons that the final target structures demand.10<\/sup> Diagnostics and biologics also heavily utilise carbon-based materials as constituting building blocks, processing aids, single-use reactors, or packaging materials. Currently, these organic compounds including plastics predominantly originate from fossil carbon derived from mineral oil, natural gas, or coal and are converted into carbon dioxide (CO2<\/sub>) and other decomposition products released into the atmosphere during production or at the end of life of the manufactured goods or auxiliaries.<\/p>\n\n\n\n The mitigation of global warming urgently calls for CO2<\/sub> neutrality, which can be reached if the carbon flux is closed. The transition to a closed carbon flux we call defossilisation. Organic materials have several routes through which defossilisation could be achieved:<\/p>\n\n\n\n Recycling is well established for standardised processes like solvent regeneration or polyethylene terephthalate (PET) recycling in commercial manufacturing and will continue to play a key role in the circular economy.11<\/sup>\u00a0Recycling also has great potential, but there are significant limitations due to the high quality requirements and regulatory barriers (eg, for unused medicines).12<\/sup>\u00a0In the vast majority of all cases, if ever, only thermally or chemically recycled materials can hence be used.13,14<\/sup>\u00a0Beyond the core theme of this article, it is worth mentioning that recycling is specifically crucial for inorganic catalysts (and other materials) so that further environmentally destructive mining and landfilling are avoided.15<\/sup><\/p>\n\n\n\n Organic chemicals from renewable resources (so-called defossilised organic chemicals) are increasingly the focus of the industry and there are promising alternatives like new solvents being marketed.16,17<\/sup> However, care must be taken to ensure that chemicals from biomass are not produced in competition with food production and do not have a negative impact on the environment or natural habitats. Consequently, byproducts of existing value chains or biotechnological methods with rather slim land use are the only methods to be used long-term.<\/p>\n\n\n\n CCU has considerable unexploited potential. It\u00a0starts with capturing gaseous oxidised carbon (CO2<\/sub>\u00a0or CO) ideally from concentrated point sources, eg, waste incineration, cement works or biogas power plants, and thus actively prevents it from entering the atmosphere. The captured carbon is then transformed into high-value organic chemicals that can then be used as feedstock for product manufacturing.18<\/sup>\u00a0CCU can hence be operated without any carbon derived from fossil fuels. This advantage comes however at the expense of considerable power or heat requirements for the production of chemical reduction equivalents (eg, hydrogen) required for recharging the CO2<\/sub>-derived carbon atom with electrons.<\/p>\n\n\n\n All the above-mentioned routes allow reduction of greenhouse gas emissions. In addition, defossilisation avoids the destruction of natural resources and habitats through the extraction of natural resources. At the same time, dependence on the volatile and unreliable fossil raw material markets and on raw material-based autocracies are reduced.<\/p>\n\n\n\n There are currently several challenges to be overcome to achieve large-scale provision of defossilised organic compounds\u201d<\/p>\n\n\n\n There are currently several challenges to be overcome to achieve large-scale provision of defossilised organic compounds. Sourcing of defossilised raw materials is currently made more difficult as standard databases and systems do not provide information about how much coal, crude oil or natural gas is used to produce a given organic chemical or plastic. Beyond this lack of transparency regarding the source of raw materials, comprehensive end-to-end information about the manufacturing process and energy sources must also be considered to prevent regrettable substitutions from a sustainability perspective and to avoid falling into the trap of greenwashed products.<\/p>\n\n\n\n Despite the fact that the origin of chemicals is already addressed in the Green Chemistry Principles devised by Anastas and Warner,19<\/sup> awareness of this topic throughout the chemical industry is still limited. Defossilisation of pharmaceutical supply chains has only recently been assessed for the first time.9 In particular, the option of CCU is not widely considered. As such, ccloop, a cross-industrial collaboration of Swiss companies and international information platform, was recently founded with the mission to increase awareness and initiate activities to drive CCU implementation.<\/p>\n\n\n\n While there has been significant progress in the field, CCU capacities are still small and organic chemicals from CO2<\/sub>are scarce. Large-scale manufacturing of defossilised chemicals like methanol could create a segue for a CCU industry and represent a first milestone. The advantages are that the basic technology and process for methanol refinement to more sophisticated commodity chemicals is in place and that methanol as such is used in many different fields. In addition, the emerging Power-to-X technologies (also known as PtX or P2X) are an important starting point for a broadening range of defossilised organic substances.20,21<\/sup><\/p>\n\n\n\n \u201cAs the contribution of costs of organic chemicals used as feedstock to the operating expenditures is small, the pharmaceutical companies can spearhead and guide the transition.\u201d<\/p>\n\n\n\n The economic models for the transition to defossilised chemistry still need elaboration. However, it is already clear that the investments will be gargantuan. In order to justify them, the future infrastructure and facilities must be written off over decades. Furthermore, entire value chains must be redesigned and the CO2<\/sub> emitters (especially point source emitters), chemical industry and power sector, downstream users, eg, healthcare industries and their customers, and healthcare providers need to be coordinated, informed, sensitised and must work out contractual frameworks to de-risk the investments. Therefore, costs for defossilised organic substances (including plastics) will initially be higher than for the conventional fossil-based counterparts but will come down in time once the virtuous cycle of increased demand stimulating scaling and innovation is started. As the contribution of costs of organic chemicals used as feedstock to the operating expenditures is small, the pharmaceutical companies can spearhead and guide the transition.<\/p>\n\n\n\n Another challenge is that the entire field of real-zero CO2<\/sub> chemicals is yet to be regulated in a favourable manner by legislation or incentivised by tax instruments. Certification systems designed to reduce the financial burden of buyers willing to pay a premium price for organic chemicals produced from sustainable carbon would accelerate the transition. Similarly, pragmatic technical solutions carefully considering means for integrating defossilised material streams into existing large\u2011scale facilities of the chemical industry are needed. In light of long due geoeconomic adjustments, one of the most important tasks of advocacy in the near future will be to draw the attention of policymakers and legislators to the challenges and opportunities ahead, and to call for a long-term strategy and close coordination of the energy and chemical sectors.<\/p>\n\n\n\n CCU has the potential to reduce dependence on feedstock produced offshore and also adds value to CO2<\/sub> as a starting material\u201d<\/p>\n\n\n\n When making near-term decisions, the long\u2011term strategic impact on the development of the European \u2013 and global \u2013 economic markets must also be considered. Importantly, CCU guides investments and emitted CO2<\/sub> into a productive path and holds the promise to close supply chains within economic areas. To this end, CCU has the potential to reduce dependence on feedstock produced offshore and also adds value to CO2<\/sub> as a starting material. While trusting in the innovative power of the energy sector for CO2<\/sub>-neutral electricity and heat production, implementation of CCU can potentially contribute to business continuity and maintenance of the European manufacturing base and provides an economic incentive to commercially exploit the inherent potential of CO2<\/sub> as a feedstock. The production of organic chemistry in the vicinity of geographically widespread point sources of CO2<\/sub>, eg, waste incineration plants or cement works, may also harbour structural policy opportunities. Production and value creation can be regionalised and decentralised, which could lead to a more resilient economic structure.<\/p>\n\n\n\n The lengthy validation of defossilised organic chemicals and plastics for the healthcare sector will take several years.<\/p>\n\n\n\n So, when could the goal of a net zero pharmaceutical industry be achieved? In the context of CO2<\/sub> neutrality, the years 2030 and 2050 are mentioned as crucial milestones. The year 2030 as a target date for any field is perhaps somewhat overambitious because the scale-up will last until the end of this decade and the lengthy validation of defossilised organic chemicals and plastics for the healthcare sector will take several years.<\/p>\n\n\n\n The year 2050, however, does not seem ambitious enough for an innovative and financially strong industry such as the healthcare industry. We believe that some industry pioneers, the best in class, could and should reach the real zero goal much sooner. It will be important that scaling and validation do not wait for each other, thus creating an unnecessary chicken-and-egg problem. <\/p>\n\n\n\n Martin Held<\/strong> graduated as a technical biologist from the University of Stuttgart and received his PhD for the development of a scaled biocatalytic process for the manufacturing of fine chemicals with whole cell biocatalysts from the Institute of Biotechnology of the Swiss Federal Institute of Technology (ETH).
