The Circularity Edge With Ken Alston
The WRITE Thing in Bogota, Colombia

The WRITE Thing in Bogota, Colombia

October 30, 2019

Today's episode tells the story of a humble pencil - Lapiz Grun.


It's an entrepreneurial venture to benefit vulnerable people in Colombia financially while simultaneously creating a closed loop cycle - for a sustainable circular economy - in graphite and in paper.

I am indebted to Juan David Pinzon, Jeffrey Jimenez and Ian Carlo Jimenez for contributing to this episode with their creativity and passion for making a difference in Bogota, In Colombia and the world.




Ken Alston with Jeffrey Jimenez at the CEID 12th Annual International Environmental Conference in Bogota, Colombia October 22, 2019.

Their project is an INSPIRATION and forms a model for what anyone can do anywhere.

How many materials you we imagine taking out of the waste stream and reconverting them to valuable goods and services.

Individually, initiatives like these seem small, but collectively they are HUGE.

Economic, social and environmental creativity and innovation - that's the heartbeat of a sustainable circular economy.

Technical & Biological Cycles in a Sustainable Circular Economy

Technical & Biological Cycles in a Sustainable Circular Economy

August 20, 2019

In this episode of The Circularity Edge, Ken Alston discusses the principles of Circular Design and the need to design into safe technical and/or biological cycles. The need to design for multiple sustainability outcomes is reviewed along with examples of solar and wind turbines which are moving energy to non-renewable forms but are not currently designed for the circular economy.

The so-called "Butterfly diagram" from the Ellen MacArthur foundation is derived from the Technical and Biological cycles from the book "Cradle to Cradle - Remaking the Way We Make Things", by William McDonough & Michael Braungart, North Point Press, 2002.

Note: In reality the technical cycle is in the biological cycle as we are all on the Earth and are part of its biological cycle.

Introduction to Sustainability and the Circular Economy

Introduction to Sustainability and the Circular Economy

August 18, 2019

In this podcast I'll discuss the beginnings of the Industrial Revolution and where the concept of Sustainable Development came from. I'll talk about how for 32 years we've struggled to achieve "sustainability" and why the business response for over 27 years of "Eco-efficiency" is insufficient to the task. I'll introduce the concept of "Circular Economy" and begin to explain what it is.
