The intention of this portfolio is to provide an overview of potential areas for collaboration.

Naturally, the experiences below have been co-creations by many people. I am grateful that I could be part of the following teams and projects:

Design and innovation tools

Tailored innovation tools and processes in companies

As a consultant, I supported a visionary family-owned business in its creation of a circular innovation tool, bringing in learnings from the creation of the Circular Design Guide, examples of other tools and best practices in the circular design ecosystem. We developed creative prompts and tips for the innovation teams during the concept creation and development stages. The tool is now being used by the whole innovation team in the creation of new products and services, as well as the re-design of the current product range.

Circular Design Guide

As a project manager at the Ellen MacArthur Foundation, I have helped co-create the Circular Design Guide in collaboration with IDEO. This tool combines design thinking with circular economy principles and has been accessed by 500,000 people from 150 countries since its launch in 2017.

You can freely access the methods and resources on the Circular Design Guide.

Circularity roadmap

Together with Sarra Ganouchi from Reform, I supported an international business in its creation of a 2030 roadmap to achieve its ambitious circular economy commitments. Through shared working sessions, we
  • reviewed the building blocks of successful circular transformations and assessed the business across key dimensions using our Circular Economy Assessment framework
  • looked at best practices across these building blocks, connected the client with pioneers for exchange and shared a compilation of practical resources
  • discussed the necessary set-up for radical and incremental innovation to reach 2030 goals
  • defined six steps on the 2030 journey and key elements of the leadership narrative and programme

The strategy project was followed by capability-building sessions for the innovation teams.

Circular strategy workshops and cards

Building on the development of the Circular Design Guide, the Circular Strategy Cards and workshop packages support organisations in redesigning their products and business models for a circular economy.

You can download the circular strategies workshop here.

Strategy projects

As a consultant at McKinsey & Company, I supported clients in Switzerland, Germany and the Middle East across various strategy projects between 2012 and 2014.

Ecosystem building

Swiss Circular Design Ecosystem

Sarra Ganouchi and I are passionate about contributing to the ecosystem and practice of circular design. Currently, we focus on
  • supporting Pro Helvetia on circular design, such as on the Circular Design Workshop for young talents
  • collaborating with Design Prize Switzerland as nominators and on their DPS Retreat on circular design
  • hosting activities for the open community of the Circular Design Circle at the Impact Hub

Circular Design Leaders Forum, Ellen MacArthur Foundation

As a freelance consultant, I have helped build the Circular Design Leaders forum together with the team at the Ellen MacArthur Foundation. The forum is a pre-competitive space for leading companies to discuss challenges, exchange best practices, and develop circular design resources. The intention is to catalyse the circular design practice across organisations and support teams in their innovation processes.

One of our milestones in 2022 was a 3-day design sprint on the topic: How does a circular-ready organisation of the future look like? Here is a quick video summary.

As a co-founder, I have helped build the student organisation together with Kai, Stella and Pierre to facilitate volunteering for students in the education sector.

We prototyped a first project with a school and established a student organisation to support others on the journey. Since then, many generations have led and evolved P.I.E.C.E.S enabling new volunteering projects every year.


System change initiatives

Circular Design Programme, Ellen MacArthur Foundation

As Creative Lead, I have helped shape the circular design narrative and thinking at the Ellen MacArthur Foundation 2017-2021. Circular design embeds circular economy principles in the innovation process and helps us meet customer needs decoupled from ‘linear’ material flows. Thereby it addresses systemic challenges such as climate change, biodiversity loss and pollution at the root and provides us with a fresh innovation lens.

As part of this, I have been involved in collaborations with other organisations:

New Plastics Economy: Rethinking the Future of Plastics

As a project manager, I have helped envision, research and write a report by the Ellen MacArthur Foundation and McKinsey & Company that was launched at the World Economic Forum 2016.

It outlined a circular economy vision for the plastics industry and was the starting point for the 10-year systemic change initiative: ‘The New Plastics Economy Initiative’. The initiative today unites hundreds of global organisations behind a common vision and targets for a circular economy for plastic.

You can find the report here.
