Energy Use in the Pharmaceutical Industry: Attaining Net Zero

The pharmaceutical industry plays a crucial role in improving global healthcare, but it also has a significant impact on energy consumption and environmental sustainability. As the demand for pharmaceutical products continues to rise, it is essential for the industry to focus on reducing its energy use and adopting sustainable practices. In this blog post, we will explore the various aspects of energy use in the pharmaceutical industry and discuss the measures that can be taken to promote a more sustainable approach.

Energy Consumption in Manufacturing

The manufacturing process in the pharmaceutical industry requires significant energy inputs. Whether it is synthesis of active pharmaceutical ingredients (APIs) or formulation and packaging of drugs, all steps involve energy-intensive processes. More than two thirds of the energy used in buildings is used for heating, ventilation, and air conditioning, while the rest is used for equipment and machinery operation.  A small proportion of this heat is in the form of very hot water or steam, for sterilization of equipment.

Renewable Energy Integration

To address the environmental impact of energy consumption, pharmaceutical companies are increasingly adopting renewable energy sources. Solar power systems are being installed on manufacturing facilities, while wind turbines are being utilized to generate electricity. By harnessing renewable electricity, the industry can reduce its reliance on fossil fuels and decrease greenhouse gas emissions.

We believe that geothermal is another renewable energy that has been underutilized by the pharmaceutical industry so far. When combined with modern industrial heat pumps, geothermal resources can be used to supply higher temperature thermal energy (including steam) from low temperature heat in the earth beneath the facility. Geothermal resources can also be used as a long term energy store, saving heat from waste and solar sources for when demand is highest.

Energy-Efficient Technologies

In addition to renewable energy integration, the pharmaceutical industry is investing in energy-efficient technologies to optimize energy consumption. Heat pump systems that integrate cooling and heating loads attain much higher efficiencies than heaters and chillers working in isolation. Advanced manufacturing processes, such as continuous manufacturing and process analytical technology, are being implemented to improve energy efficiency and reduce waste. Furthermore, energy management systems and smart sensors are being employed to monitor and optimize energy use in real-time.

Supply Chain Sustainability

Energy consumption goes beyond the manufacturing process; it extends to the entire pharmaceutical supply chain. From raw material sourcing to distribution and storage, energy is required at each stage. To promote sustainability, pharmaceutical companies are working closely with suppliers and logistics providers to implement energy-efficient practices. This includes optimizing transportation routes, utilizing energy-efficient packaging, and exploring alternative modes of transportation, such as electric vehicles.

Regulatory Compliance and Certifications

Government regulations and certifications are playing a crucial role in driving energy-efficient practices in the pharmaceutical industry. Many countries have implemented energy-saving initiatives and introduced stringent environmental regulations. In addition, certifications such as ISO 50001 (Energy Management System) and LEED (Leadership in Energy and Environmental Design) are being pursued by pharmaceutical companies to demonstrate their commitment to sustainable energy use.

Conclusion

As the pharmaceutical industry continues to expand, the importance of sustainable energy use becomes even more critical. By adopting renewable energy sources, leveraging energy-efficient technologies, and promoting sustainability throughout the supply chain, pharmaceutical companies can reduce their carbon footprint and contribute to a greener future. It is through collective efforts and industry-wide collaboration that we can ensure a sustainable and energy-efficient pharmaceutical sector that aligns with global environmental goals.
