A Case Study in Approaches to Achieve Decarbonisation in the Manufacture of Pharmaceutical Products

Step 1: Set Carbon Reduction Goals and Measure Current Emissions

Reducing carbon emissions in the pharmaceutical sector starts with setting clear goals and accurately measuring where things stand. Without a proper baseline, it’s impossible to create effective strategies for decarbonization.

Define Specific Emission Reduction Targets

Begin by setting SMART goals - those that are Specific, Measurable, Achievable, Relevant, and Time-bound. Align these targets with established frameworks such as the Science Based Targets initiative (SBTi) and EPA guidelines.

For example:

• Aim for a 30% reduction in Scope 1 emissions by 2030, focusing on direct emissions from owned operations.

• Address Scope 2 emissions with quicker wins, like transitioning to renewable energy sources.

• Tackle Scope 3 emissions, targeting a 20% reduction over the same timeframe, despite the complexities of supply chain and logistics emissions [8][6].

The pharmaceutical industry faces unique hurdles here. Manufacturing processes must adhere to strict quality standards, and any significant process changes often require regulatory approval. These factors can extend timelines compared to other industries.

Once targets are in place, the next step is to measure emissions with precision.

Measure Your Complete Carbon Footprint

Accurate measurement is the foundation of any carbon reduction strategy. Employ systems that track energy use and emissions across all scopes - Scope 1, Scope 2, and the more challenging Scope 3.

• Energy management systems and IoT-enabled sensors can provide real-time data on electricity, gas, and steam usage in manufacturing facilities. This granular visibility helps identify emission hotspots.

• Cross-referencing this data with utility bills and process-level metering ensures reliability and accuracy.

Scope 3 emissions, however, present a tougher challenge. These emissions stem from supply chains, transportation, and waste management, making data collection inconsistent and complex. For instance, Lupin’s 2022 analysis of 14 APIs uncovered opportunities that led to a 61% reduction in solvent and reagent consumption and a 33% reduction in synthesis steps [6]. Such insights demonstrate the value of thorough data collection.

Using digital carbon tracking platforms aligned with standards like the Greenhouse Gas Protocol or ISO 14064 can improve measurement accuracy and ensure compliance. Reliable data not only shapes strategies but also builds trust and collaboration with stakeholders.

Get Stakeholder Support Early

Securing buy-in from both internal teams and external partners early on is essential for aligning sustainability goals and ensuring smooth implementation.

Internally, this means involving departments like operations, procurement, and compliance to integrate emission reduction goals into daily workflows. Externally, collaboration with suppliers is critical, as supply chains account for a significant portion of the industry’s carbon footprint. Sharing data, setting expectations, and working together on reduction initiatives can help overcome barriers like inconsistent data collection.

Partnering with sustainability experts, such as Council Fire, can further streamline strategic alignment and execution.

Step 2: Reduce Energy Waste and Improve Operations

Once you've set your carbon reduction targets and assessed your baseline emissions, the next step is to tackle energy waste. Improving operational efficiency not only reduces emissions but also enhances overall performance. For industries like pharmaceuticals, where energy-intensive processes are the norm, this step becomes even more critical.

The pharmaceutical and biotech sectors saw their share of global carbon emissions rise from 3.9% in 2021 to 5% in 2022, highlighting the pressing need for efficiency improvements [2]. Optimizing energy use not only cuts emissions but can also lead to considerable cost savings.

Install Heat Recovery and Reuse Systems

Heat recovery systems are a smart way to repurpose waste energy. These systems capture heat from operations like steam generation and water purification, redirecting it for other uses within the facility. Tools like condenser economizers and heat pumps can cut emissions by 5–10% and typically pay for themselves within five years [2] [6]. One example is a major pharmaceutical company that collaborated with ENGIE Impact to implement renewable-powered heat pumps and heat recovery systems. This initiative contributed to a 7% reduction in total cost of ownership and supported their goal of cutting Scope 1 and 2 emissions by 50% by 2030 [1].

Replace Old Equipment with Energy-Efficient Models

Outdated equipment can be a major drain on energy. Replacing older systems - such as chillers, boilers, HVAC units, and water treatment equipment - with energy-efficient models can significantly reduce both energy consumption and emissions. Prioritize equipment with strong energy ratings, such as those certified by ENERGY STAR, and ensure compliance with regulatory and operational standards. For instance, Lupin revamped its processes by integrating modern equipment and adopting green chemistry principles, achieving a 61% reduction in solvent and reagent use and cutting synthesis steps by 33% [6]. Similarly, Pfizer’s Puurs plant reduced CO₂ emissions by 60% in 2023 through digital upgrades and modernization efforts [8].

Perform Regular Energy Audits

Energy audits are a powerful tool for identifying inefficiencies and prioritizing improvements. Conduct annual audits to evaluate energy usage in critical systems like HVAC and production equipment. Using standardized processes, digital tools, and cross-functional teams can help ensure accurate results [2] [4]. Common issues uncovered during audits include excessive energy use in HVAC systems, outdated equipment, and poor insulation. These challenges can often be addressed through upgrades, process optimization, and heat recovery solutions.

While audits can face hurdles such as high upfront costs and regulatory complexities, these challenges can be managed by focusing on high-return projects, seeking external funding or incentives, and involving stakeholders early. Partnering with consultancies like Council Fire (https://councilfire.org) can provide strategic guidance to navigate these challenges. Additionally, digital energy management systems offer real-time monitoring, advanced analytics, and transparent energy consumption reporting, making it easier to implement and track improvements [4].

Step 3: Switch to Renewable Energy Sources

Once you've optimized energy efficiency, the next big move is transitioning from fossil fuels to renewable energy. This change not only cuts emissions significantly but also helps stabilize long-term energy costs. Recent data on emissions highlights just how urgent it is to embrace renewables.

For pharmaceutical manufacturers, renewable energy offers several practical options. You can generate clean energy onsite, buy it from external providers, or electrify heating and cooling systems to run on renewable electricity. Each approach has its own benefits, and combining them can lead to even greater results. Here are three key strategies to consider for making this transition:

Install Onsite Renewable Energy Systems

Onsite renewable systems, like solar panels, allow you to produce clean energy directly and reduce reliance on the grid. Solar photovoltaic systems are particularly effective, with installation costs ranging from $2 to $4 per watt. Federal and state incentives can help offset 20-30% of these upfront costs [2].

Wind turbines are another option for facilities in areas with strong wind resources, while geothermal systems can deliver both electricity and heating/cooling in regions with suitable conditions. These systems are designed to integrate seamlessly with U.S. grid standards and can be tailored to meet your facility's energy needs.

A great example of success in this area is Johnson & Johnson. The company has committed to using 100% renewable electricity worldwide, with its U.S. facilities powered by a mix of onsite solar installations and wind energy purchase agreements [2][4]. Their efforts show how renewable energy can support ambitious goals for reducing carbon emissions.

Before installing onsite systems, it's important to consider factors like available roof or land space, local zoning and permitting requirements, and how the system will connect to your current energy infrastructure. Compliance with FDA regulations for energy reliability and EPA environmental guidelines is also crucial. While the capital investment varies depending on the system size and technology, federal tax credits for solar and wind projects can significantly improve the financial outlook.

Purchase Renewable Energy from External Providers

If onsite systems aren't feasible, purchasing renewable energy from external sources is a practical alternative. Options like Power Purchase Agreements (PPAs), Renewable Energy Certificates (RECs), and green tariff programs provide efficient ways to reduce Scope 2 emissions without large upfront investments.

PPAs allow you to secure long-term renewable energy at fixed rates, offering both emissions reductions and cost stability. RECs help verify your renewable energy use and fulfill sustainability reporting requirements. For smaller facilities, utility green tariff programs provide an easy way to source renewable electricity without the need for complex contracts.

Pfizer has successfully used this approach by entering into wind energy PPAs while also incorporating geothermal heating and cooling at specific manufacturing sites. This dual strategy helps lower energy costs and emissions while maintaining operational flexibility [2][4].

External procurement options are ideal for reducing Scope 2 emissions quickly and with minimal initial capital. However, it's essential to carefully review contract terms, pricing, and the location of the renewable energy source to ensure you're achieving genuine environmental benefits. These methods align well with regulatory standards and cost-saving objectives, streamlining both environmental and operational goals.

Convert Heating and Cooling to Electric Systems

Switching your heating and cooling systems to electric options, such as electric boilers and heat pumps, eliminates fossil fuel use and directly reduces onsite emissions.

Heat pumps are becoming increasingly popular in pharmaceutical manufacturing, often paired with electric heater backups to ensure reliability during critical processes. While the upfront costs for electrification can be high, the long-term benefits include immediate emission reductions and a strong return on investment over time [2].

Planning is key for this transition, as system reliability is critical for manufacturing operations. Electrical infrastructure may need upgrades to handle the increased power demands, and backup systems are vital to ensure compliance with FDA requirements for uninterrupted production.

Step 4: Use Green Chemistry Methods

Revolutionize your manufacturing processes by adopting green chemistry principles. This strategy emphasizes redesigning chemical processes to reduce waste, minimize hazardous substances, and lower energy use - all while maintaining the high-quality standards expected in pharmaceutical production.

Green chemistry provides an effective path for pharmaceutical manufacturers to cut emissions by up to 30% through smarter, more efficient processes [6]. Beyond the environmental benefits, it often leads to cost savings by improving efficiency and reducing material use. Below, we’ll dive into specific methods that balance waste reduction, cost efficiency, and stringent quality requirements.

Recycle and Recover Solvents

One of the most impactful ways to embrace green chemistry is through solvent recovery. By installing technologies like distillation columns or membrane filtration systems, manufacturers can capture and purify used solvents for reuse. This not only reduces environmental impact but also slashes material costs.

Solvent recovery systems deliver quick returns on investment by saving on material purchases and cutting disposal fees. These systems can often be integrated into existing manufacturing setups with minimal disruption to production schedules.

A great example of this is Lupin, which implemented green chemistry improvements across 14 Active Pharmaceutical Ingredients (APIs) in 2022. Their efforts in solvent recovery and process redesign led to a 61% drop in solvent and reagent use and a 33% reduction in synthesis steps [6]. This shows how targeted solvent recovery can achieve both environmental and financial gains.

When adopting solvent recovery, consider the types of solvents your processes use, the volume of waste generated, and the purity levels required for reuse. Different technologies suit different solvents, so it’s essential to evaluate your current usage patterns before investing in equipment.

To measure success, track metrics such as the percentage of solvents recovered and reused, total solvent waste diverted, and cost savings from reduced material purchases and waste disposal fees.

Design Processes to Minimize Waste

Beyond solvent recovery, refining your synthesis processes can further reduce waste and improve efficiency. High-yield synthesis methods and techniques like continuous flow chemistry are particularly effective in lowering the Process Mass Intensity (PMI) - a key metric that reflects the total material used per unit of product manufactured.

Streamlining synthesis steps not only minimizes waste but also reduces energy use and processing time. Achieving this requires collaboration between R&D teams, process engineers, and production staff to identify and implement improvements.

Continuous flow chemistry is worth special attention. Unlike traditional batch processes, this method offers better control over reaction conditions, leading to higher yields and less waste. While the upfront investment in equipment can be substantial, the long-term benefits include increased safety, reduced environmental impact, and often lower operating costs.

Use PMI as your main metric for tracking waste reduction. A lower PMI indicates more efficient material use and less waste per unit of product. Regularly auditing your processes can uncover further opportunities to enhance efficiency and reduce waste.

Maintain Regulatory Compliance During Process Changes

While reducing emissions and waste is essential, it’s equally important to maintain compliance with regulatory standards. Any changes to manufacturing processes must align with the requirements set by the FDA and EPA to ensure product safety, efficacy, and environmental protection.

Engaging regulatory teams early in the process change cycle is crucial. This proactive approach helps identify potential compliance challenges before they escalate, ensuring that all modifications meet safety and quality standards. Risk assessments, validation studies, and robust quality management systems are essential for navigating these changes successfully.

Interestingly, many green chemistry improvements not only reduce environmental impact but also enhance process control and product quality. The key is to demonstrate these improvements through proper validation and regulatory submissions.
