The pharmaceutical industry is subject to numerous standards, laws and guidelines. Process plants and other operational infrastructure form a functional whole. An understanding of these parameters is necessary in order to develop, and implement, an overarching, tailored decarbonization concept. For the pharmaceutical industry, production is the essential core element. Therefore, following a process-focused project management approach, in which the production process is at the center of consideration, allows a company to scrutinize existing standards and define potentials for energy optimization. There are numerous possibilities to achieve the goal of optimizing energy consumption of bioprocessing plants and such control models can often be created with little physical effort. The decisive factor is that the corresponding requirements are already defined in the preliminary planning of a project. Finding a strategic and structured approach to energy optimization and decarbonization is a major challenge for companies - it needs to be ambitious, but, at the same time, realistic. The goal is to align an external perspective with an internal perspective of the company. The result is a structured cost-benefit analysis showing how much CO2 is saved by each measure and the incumbent costs. This provides a clear picture of which reduction potentials are possible.
