Net-Zero Pledge: CDMOs Go Greener

Contract Pharma, 19 July 2023

In the year 2021, when COP26 was held in Glasgow, Sterling Pharma Solutions came out announcing an ambitious target: to reduce the CDMO’s overall emissions by 50% by 2025 and by doing so, joining the international community’s fight against climate change.

The CDMO Recipharm expanded its pressurized metered dose inhalers (pMDI) product development the following year to accommodate the switch to new propellants, which have 90% to 99.9% lower global warming potential than HFA134a.

In the same year, WuXi STA won top scores from EcoVadis, a provider of business sustainability ratings, for their API and formulations factories located in China.

Again, in January, Samsung Biologics was awarded the 2022 Sustainable Markets Initiative’s Terra Carta Seal in recognition of its commitment to achieving net zero greenhouse gas emissions across its direct operations and supply chain by 2050 or earlier.

Similarly, Cytiva says its goal is to eliminate polystyrene from the company’s packaging materials and supply chain by 2025.

These are just a few examples of a growing trend.

A number of CDMOs are accelerating their environmental drive setting themselves far more ambitious targets than these as sustainability goals are now becoming one of the most urgent business strategies facing pharma companies.

Presently, analysts say that there is a move away from sustainability being seen as something that is nice to have, to something more fundamentally important to businesses.

"Sustainability commitments are no longer just desirable," says Jon Peers, director of sustainability at Hovione. "They are becoming mandatory, both directly by our regulatory authorities and indirectly by the regulatory and financial requirements faced by our customers."

Hovione, a leader in spray drying and particle engineering, became a Certified B Corp in 2017 integrating an innovative community of companies that use the power of business to solve social and environmental problems.

Pharma’s outsized impact

Medicine making leaves an environmental impact which is quite massive. Estimates show that the pharmaceutical sector is accountable for as much as 4.4% of worldwide emissions—and if no action is taken—its carbon dioxide, a greenhouse gas (GHG), emissions are predicted to triple by 2050.

Not only manufacturing but the distributing and transporting of medicines from the factory to the patient also carries a substantial environmental footprint.

According to the Sustainable Markets Initiative’s (SMI) “Decarbonizing Healthcare Supply Chains” whitepaper, the biopharma industry is responsible for 4–5% of global GHG emissions, with most of its carbon footprint coming from supply chain, manufacturing, retail, and logistics.

Having felt the heat, many leading pharma companies are already ahead of the curve on the path to net-zero carbon emissions. They have made carbon neutrality and net-zero pledges, some for as early as the next decade.

Sustainability metrics: High on the agenda

CDMOs demonstrate a strong determination to reduce their carbon emissions as environmental performance is being added to the list of demands by their clientele.

Industry reports show that full waste recycling, green power percentage and green chemistries currently play a crucial role during negotiations between pharmaceutical companies and the CDMOs.

These “sustainability metrics” are becoming increasingly important even as technology, track record, capacity, and cost are still the most important criteria for selecting CMOs/CDMOs.

"Recognizing our commitment and progress made towards our sustainability targets, clients will seek out not only providers of CDMO services but also those companies with the competence to execute these services in harmony with the client’s respective sustainability goals," says Paul Zuechner, director, sustainability and reliability engineering, pharma services, Thermo Fisher Scientific.

Thermo Fisher, which offers end-to-end solutions to small molecules as well as biologics, announced an acceleration of the target to reduce scope 1 and 2 GHG emissions to more than 50% by 2030.

Zuechner maintains that the increasing focus on sustainability, resource and decarbonization quantifications is now elevating sustainability towards an equal project deliverable on par with cost, quality, and timelines.

The sustainability initiatives by CDMOs are not only driven by customer preference but also by regulatory requirements, according to Peers of Hovione. Regulated and standardized reporting is there. The European Corporate Sustainability Reporting Directive (CSRD) together with the European Sustainability Reporting Standards (ESRS) is significantly raising the required levels of compliance.

On top of this, businesses must meet their stakeholder’s requirements to provide material information that stands up to scrutiny.

Headquartered in Loures-Portugal, Hovione believes that it is simply not possible to meet the challenging goals that have been set by the companies themselves on sustainability without further innovation, particularly through process intensification and the greening of pharmaceutical intermediate and API manufacturing.

Safety via process efficiency

Without question, manufacturers are aggressively pursuing various strategies to enhance processes as it becomes a business imperative for the service providers.

"Olon tries to optimize plants' performances, in order to reduce the amount of energy, materials and natural resources they need,'' says Giorgio Bertolini, senior vice president of R&D, Olon Group, a global leader in the development and production of APIs, headquartered in Milan, Italy.

Olon is working on cutting-edge R&D processes applied both to chemistry, in terms of flow chemistry, photochemistry, and electrochemistry, and to biotechnologies. Investing in and developing technological advances allows the organization to combine well-established practices with new ones, to guarantee efficient and successful manufacturing processes, at the same time ensuring safe, fast and cost-effective commercial processes.

"We consider climate protection and the related reduction of GHG emissions to be a top priority," emphasizes Bertolini. To increase efficiency and reduce the energy required for production, especially in the functioning of reactors, Olon is implementing several continuous manufacturing processes, investigating both the flow chemistry approach and the continuous stirred tank reactors (CSTR)

These approaches entail leaving no batch reactors with loading and unloading phases but keeping constantly active production units—either microreactors or small classical reactors. The outcome is that, at the same levels of production, continuous manufacturing processes can reduce the footprint of the manufacturing process in comparison with standard methods.

This innovative production technique, he explains, enables a double positive impact in terms of sustainability. Indeed, it allows for the use of smaller amounts of material for the unit time, therefore resulting in increased local temperature control and in the possibility to avoid extreme temperatures, making the manufacturing process less energy intensive. It also provides greater safety for operators.

The industry is now facing a change of paradigm, avers Bertolini, in which there is a continuous exchange of knowledge and information between the chemical and engineering sectors, which eventually results in the creation of new specific know-how and business synergies.

Olon started constructing a new facility at its Rodano site (Milan, Italy) dedicated to ultra-potent compounds, used for antibody-drug conjugates (ADCs).

Circular business models that combine a responsible use of natural resources and raw materials with a responsible waste management approach are what Olon strives to promote, according to Bertolini.

Greening the supply chain

To reduce effluents and design safer alternatives to hazardous processes organizations extensively explore the use of safer and more sustainable chemicals.

This green chemistry approach can minimize the risk of impact on the environment to a great extent.

Olon, for instance, is focusing on green chemistry projects for the replacement of chlorinated solvents and the reduction of critical substances which could be particularly toxic, especially in new manufacturing processes.

Not only in manufacturing, quite a few companies are investing in greener biofuels (rather than diesel) for vehicles. As mentioned, distributing and transporting medicines from the factory to the patient also leaves a large carbon footprint. Temperature-sensitive products are loaded onto refrigerated vehicles to maintain cold-chain which require a considerable amount of energy to power.

Environmental credentials are now integral to all supply chain decisions. There is almost a universal consensus on this approach, shows the CPHI sustainability sentiment index.

In data released ahead of CPHI Frankfurt 2022, 95% of industry executives suggest it is either “important” or “extremely important” (52%) to have visibility on supply chain partners.

Scope 3 emissions: Key challenge

In comparison to the scope 3 tally that falls not within the organization's boundary, scopes 1 and 2 emissions are relatively minor. However, within these scopes, electrical energy consumption in manufacturing and the fugitive emissions from hydrofluorocarbons (HFC) released during pMDIs product lab testing are the highest.

pMDIs and anesthetic gases can be particularly serious for global warming. The UK and several countries in the EU block including Belgium, and the Netherlands are now promoting dry powder inhalers in prescription guidelines. Meanwhile, the common general anesthetic desflurane is being replaced by lower-carbon alternatives in countries like Sweden.

Scope 3 emissions, however, make up the majority of the pharma sector’s carbon footprint. Even though many CDMOs have set ambitious targets like striving for carbon neutrality across the entire value chain already by 2030, many are still simply focusing on scope 1 and 2 emissions.

Observers say that this is largely because the need for sustainability in the pharmaceutical industry has become more apparent only in recent years.

Another concern is the cost factor.

According to Peers of Hovione, decarbonization costs in particular can be very expensive and require strategic planning and commitment from senior management to meet associated capital and operational costs.

The sustainability challenge, he says, needs to be considered throughout the drug development life cycle, starting from simple assessments against sustainability principles and metrics early on and growing in detail and robustness as the drug progresses through the cycle.

Shift in focus

Experts, however, see a shift across the industry. Discussions about sustainability are taking place at the highest levels. An increasing number of pharmaceutical companies are prioritizing it when discussing projects with their CDMO partners.

"Be it the fulfillment of new technical capabilities, increased production capacities, advancing regulatory compliance and now sustainability target introductions—it’s natural for us to solve for and achieve our customers’ product development, manufacturing, and corporate goals in partnership,” says Zuechner of Waltham, Massachusetts-headquartered Thermo Fisher.

It will be essential for drug makers and their CDMO partners to work together on questions of sustainability, and to be ready with a sustainability agenda before starting to work on the project, in the coming years.

It is important for CDMOs, says Peers, that their clients and suppliers share the same vision of a more sustainable industry as collaboration across the value chain is key to leveraging knowledge and driving change.

Inhalation CDMO Market Growth Analysis & Forecast 2025 to 2035

Jun 25, 2025

Pharmaceutical innovators face many challenges when developing new products; as such, getting them to market in a timely, safe and cost-effective way is critical. The use of continuous manufacturing technologies can help to overcome some of the most pressing early-stage obstacles Improving production methods for generic drugs or extending the lifecycle of existing oral solid dosage (OSD) forms is an integral part of the day-to-day operations of many global pharmaceutical companies. At the same time, when formulating new molecular entities, issues such as reducing the cost-per-tablet, increasing patient safety and optimising the price/performance balance of a new drug are common daily concerns. During the early stages of research and development (R&D), however, the availability of the active pharmaceutical ingredient (API) is limited. As such, there is an absolute requirement for process equipment that can produce just a few hundred grams of finished product to fast-track novel formulations.  The changing perspectives of regulatory bodies such as the US FDA and EMA now mean that there’s a better way to improve both supply chain efficiency and product throughput. It’s the 21st century, the pharmaceutical industry is less risk-averse these days, and it’s well-known that continuous manufacturing (CM) solutions can accelerate product development, reduce costs, improve operational economics and make production more agile. CM can accelerate the development of innovative products and increase the quality assurance of existing ones by driving process excellence. It’s a more efficient and flexible technology, offering more consistent and reliable tablet production with the reduced use (and loss) of resources such as precious APIs and raw materials. Additional benefits include less downtime and minimal manual intervention.   Introducing ConsiGma® The ConsiGma® portfolio from GEA Pharma & Healthcare is a multipurpose platform that has been designed to transfer powder into coated tablets in development, pilot, clinical and production volumes in a single compact unit. The system can perform the dosing and mixing of raw materials, wet or dry granulation, drying, tableting and quality control, all in one line. And, as it can produce granules continuously, there is no waste during start-up and shutdown and the batch size is determined simply by how long you run the machine. Quality is measured throughout the process and, as such, drastically reduces the cost-per-tablet. The ConsiGma® concept combines Quality by Design (QbD) principles with Design of Experiments (DoE) to explore and optimise a wide range of process parameters with less product in a shorter time frame.  Dr James (Jim) Holman, Senior Director of Technology Management, Pharma Solids, at GEA, takes up the story: “Our stance with CM is consistent in terms of how we approach both commercial-scale and early development work. We’ve created a range of unit operations or submodules, for example, that are ideal for process or product optimisation studies. For wet granulation, for instance, we have the ConsiGma®-1. You can use the same granulator that you would for a larger-scale machine but simply connect it to a single cell of a six-cell fluid bed system.” He adds: “Our approach to R&D is that we try to scale-out rather than scale-up. Our equipment is specifically designed so that you can process a plug or product key in a very controlled way to limit material usage.”  Jim can cite a litany of Big Pharma organisations that have “developed molecules on our systems in R&D, subsequently transferred them to production and have now had them approved for sale and use.” He acknowledges that, compared with a traditional production-scale system, there are advantages and disadvantages to consider. But he emphasises: “To support our thinking and what we’ve done, there are a lot of commercial products on the market that were made using GEA CM systems.”   The ConsiGma®-1: an integrated R&D solution Developed as a mobile, plug-and-play laboratory-scale version of the GEA’s continuous tableting platform, the ConsiGma®-1 can convert powders into dry granules and is ideal for small-scale research and development applications. It’s specifically designed for maximum flexibility and simplicity in early formulation development work. And, because of its rapid processing times and ability to run batches of a few hundred grams up to 5 kg or more, it’s ideal for developing formula and process parameters using DoE — which can then be scaled-out to the full-size ConsiGma® wet granulation system. “With ConsiGma®, we can help companies all over the world to maximise their R&D efforts and capitalise on the very worthwhile expenditure by getting first-rate products to market quicker,” notes Jim. When equipped with the optional fluid bed dryer segment, drying parameters for batch sizes of 500–1500 g can be determined on the ConsiGma®-1. And, because these granulation details can be directly scaled-out to a production model (such as the ConsiGma®-25), which benefits from the same design, there is no scale-up.  Furthermore, as the retention time of the product in the system is minimal, any change in these parameters is almost immediately visible. This allows for very fast and easy exploration of the design space. The result is a better understanding of both operational capabilities and critical process parameters (CPPs), which ultimately contribute to higher levels of quality assurance and patient safety.  The ConsiGma®-1 is designed for rapid deployment, will fit into the most compact of laboratories and can be transported easily to wherever it’s needed. Installation only requires electricity and standard utilities such as water and compressed air. The system is conceived to be a “plug-and-play” installation. To enhance the R&D flexibility even further, the ConsiGma®-1 can also be configured for hot melt granulation and/or upgraded for contained processing. To cite an example, a ConsiGma®-1 unit was recently used to expedite the development process for a new product during in-house trials. Everything was running smoothly during scale-out to a commercial-size line, until one of the raw material sources had to be changed. Anticipating granulation issues due to the changed specifications of the raw material, and with a pending deadline — and not wishing to revert to the ConsiGma®-1 for redevelopment (or to clean another piece of equipment) — it was decided to tackle the issue using the production-scale CM line. Owing to the inherent flexibility of continuous processing and the transferable compatibility of the critical parameters, the correct settings were found in just a few hours using only a limited amount of product. Full production mode could be quickly reinstated with minimal disruption. The ConsiGma® DC for continuous direct compression is the most recent expansion of GEA's portfolio of cost-effective, compact and high-yield manufacturing systems. By integrating four key technologies — accurate loss-in-weight feeding, continuous blending, tablet compression technology and the online measurement of CQAs (Critical Quality Attributes), it offers a robust and flexible production method for a wide range of products in a small footprint. Of note here is that standalone plant is often used to separately test and optimise the critical unit operations before the entire line is constructed, thereby accelerating the process. This means that each manufacturing step can be enhanced without first having to run or invest in a complete process chain. One company that has benefited from this approach is Hovione, a specialist contract development and manufacturing organisation. Using a combination of standalone laboratory scale units coupled with process analytical technology (PAT) tools, computational models and powder characterisation equipment, Hovione is developing processes at the R&D scale with minimal material consumption and resources. The standalone dosing and blending unit is equipped with feeders and blenders that are identical to those used in GEA’s GMP Continuous Direct Compression (CDC) lines. Powder characterisation and the use of compaction simulations “close the circle” in terms of connecting the unit operations and allow operators to fully define the process parameters that are used in a digital twin version of the line. João Henriques, R&D Director – Oral Drug Product Development comments: “This integrated platform accelerates process development, helps to optimise formulation and product parameters and improves operational performance. It also enables the seamless scale-out of continuous tableting processes to a GMP line with reduced risk and low API consumption. This methodology has been used to successfully develop and scale-out multiple processes to CDC lines.”   Coating covered Not only does GEA have what Jim calls “grouped unit operations” for applications such as wet granulation —wherein a twin-screw granulator is combined with a single cell fluid bed — standalone systems such as dosing and blending rigs, an independent feeder and/or continuous coaters are also available. In addition, plant for direct compression can also be supplied. The ConsiGma® DC-LB Lines integrate continuous dry blending using linear blenders and tablet compression into one efficient continuous production system. Being able to accommodate differently sized blenders makes it a fully configurable setup. From an operational perspective, adds Jim, the advantage of the GEA Coater during R&D is that you don’t have to run a full-scale trial with all the associated losses of startup, shutdown, etc. All you need is a 1.5 kg plug and then, to scale-out your production, you just repeat the process. It's the same with wet granulation. Doing so gives you the certainty that you can basically repeat the same operation — or just run it for longer — to achieve commercial levels of production. Jim suggests that a well-known top-tier pharmaceutical company has recently invested in two ConsiGma®-1 units and coaters and is in the process of replacing their existing batch coating equipment with GEA machinery. “It’s now their default choice of coating technology for R&D,” he says. “With the three sizes of coating pans we offer, you have the option of using 1.5, 3.0 or 6.0 kg samples simply scaling that out.”   In conclusion Shining the spotlight on wet granulation as an example application, many of the most well-known names in the pharmaceutical sector have products on the market that were initially tested on a ConsiGma®-1 unit, subsequently transferred to a larger development and launch rig (DLR) and were then put into commercial production. Reaping the benefits of grouped unit operations during R&D enables GEA customers to expedite product development, eliminate scale-up and rapidly transfer the manufacturing process to an integrated line. Plus, by producing tablets continuously, “batch sizes” are simply determined by how long you run the machine.  It’s also helping the pharmaceutical industry to produce higher quality products, enhance drug safety, reduce its industrial footprint and decrease waste, which provides significant advantages to governments, companies and patients alike. Continuous processing is the future of pharmaceutical manufacturing. As Jim will attest, the majority of the top ten pharmaceutical companies have now confirmed that their strategy is to develop both new chemical entities (NCEs) and, when economically and technically viable, also manufacture legacy ethical and generic products using continuous technologies.   Read the full article on ManufacturingChemist.com
