1 Circular Economy keep it smart and close the loops Talke Schaffrannek, Director Applied Sustainability, BASF Company logo

2 Circular Economy Decouple growth from resource consumption LINEAR ECONOMY RECYCLING ECONOMY CIRCULAR ECONOMY KEEP IT SMART Increase efficiency of processes and enhance effectiveness of products and solutions CLOSE THE LOOPS Turn waste into resources, use natural loops 2

3 Our Purpose We create chemistry for a sustainable future 3

4 How can we steer our portfolio towards a more circular economy? How can we measure progress?? 4

We implement active sustainable portfolio steering 27,3% Accelerator:

8 How are we affected by circular economy and how can we contribute to a more circular economy?? 8

9 Circular economy transforms value chains Decoupling growth and resource consumption External factors driving the shift towards circularity Technology shifts e.g. electric vehicles Consumption changes e.g. car sharing Linear Model Disposal of molecules at end-of-life Increasingly bent models Partially renewable feedstock Some level of product recycling Start of partnering approaches New regulations e.g. EU Circular Economy package, insulation standards Circular Model (total recovery) Full re-use of molecules or carbon Design to re-use for end products

10 Our contribution to Circular Economy KEEP IT SMART Increase efficiency of processes and enhance effectiveness of products and solutions CLOSE THE LOOPS Turn waste into resources, use natural loops Our contribution combines the idea of smart business models with circular resource use
