Green chemistry tools to influence a medicinal chemistry and research chemistry based organisation

Influencing and improving the environmental performance of a large multi-national pharmaceutical company can be achieved with the help of electronic education tools, backed up by site champions and strong site teams. This paper describes the development of two of those education tools.

A deeper shade of green: inspiring sustainable drug manufacturing

Green and sustainable drug manufacturing go hand in hand with forward-looking visions seeking to balance the long-term sustainability of business, society, and the environment. However, a lack of harmonization among available metrics has inhibited opportunities for green chemistry in industry. Moreover, inconsistent starting points for analysis and neglected complexities for diverse manufacturing processes have made developing objective goals a challenge. Herein we put forward a practical strategy to overcome these barriers using data from in-depth analysis of 46 drug manufacturing processes from nine large pharmaceutical firms, and propose the Green Aspiration Level as metric of choice to enable the critically needed consistency in smart green manufacturing goals. In addition, we quantify the importance of green chemistry in the often overlooked, yet enormously impactful, outsourced portion of the supply chain, and introduce the Green Scorecard as a value added sustainability communication tool.

Inspiring process innovation via an improved green manufacturing metric: iGAL

Following our goal to devise a unified green chemistry metric that inspires innovation in sustainable drug manufacturing across the pharmaceutical industry, we herein disclose joint efforts by IQ, the ACS GCI PR and academia, leading to the significantly improved ‘innovation Green Aspiration Level’ (iGAL) methodology. Backed by the statistical analysis of 64 drug manufacturing processes encompassing 703 steps across 12 companies, we find that iGAL affords an excellent proxy for molecular complexity and presents a valuable molecular weight-based ‘fixed’ goal. iGAL thereby accurately captures the impact of green process inventiveness and improvements, making it a useful innovation-driven green metric. We conclude by introducing the comprehensive, yet easy-to-use and readily adaptable Green Chemistry Innovation Scorecard web calculator, whose graphical output clearly and effectively illustrates the impact of innovation on waste reduction during drug manufacture.
