Sandy worked for 26 years with ICI, Unilever and then Diageo. Starting as an engineer, and later adding an MBA, he held senior roles in manufacturing, supply chain, and R&D, finally as Diageo’s global head of R&D. Having built a deep understanding of the industrial system, in 2009 Sandy changed direction to work on the systemic changes needed for businesses to use resources effectively. After a Masters in Environmental Systems Engineering, he established a portfolio career, with the theme of strategic leadership of systemic change – making change a practical proposition within and between businesses. His main focus has been on the emerging topic of the Circular Economy. Sandy spent 2 years with the Ellen MacArthur Foundation, the leading Circular Economy think tank. He led project MainStream, their collaboration with McKinsey and the World Economic Forum, and started the major project now known as the New Plastics Economy. Sandy is now leading an innovative Circular Economy programme with the Toilet Board Coalition, nominated as a World Changing Ideas finalist with the Fast Company magazine. This involves working with multinationals and with SMEs in Africa, to apply the Circular Economy model to sanitation. The latest findings were published on World Toilet Day in November 2017, and introduce the “Circular Sanitation Economy” as a game-changing approach to sanitation. This improves health and achieves economic and environmental gains, by building working biological and water cycles, in the process creating multiple business opportunities. Sandy is developing wider collaborations to help businesses transition to the Circular Economy. He is setting up an expert network called Expert Circular, has worked with Zero Waste Scotland, Nestlé, and the World Business Council for Sustainable Development, and has been speaking, chairing events and writing about the Circular Economy.
