In the fourth and final session of the brand new SLL LightBytes Online series, our three speakers will be joined by guests, Emilio Hernandez and Mark Ridler for a round table discussion on a circular economy approach for the lighting industry and beyond.

Emilio is a Lighting Designer and Chair of the GreenLight Alliance, a new organisation with a mission to move towards a more circular economy.

Find out more about the GreenLight Alliance in this recent article by Emilio, featured in Arc Magazine.

In his role as Head of Lighting for BDP, Mark Ridler decided that 2020 would be the year of the circular economy for his design team. Following a period of research, discussions with stakeholders, they set about developing and changing their design process and specification to make some concrete contributions.

You can find out more about what this process involved and the work that went into it by reading Mark's article for SLL Light Lines.

Chaired by the Society's President, Bob Bohannon FSLL, this session will aim to generate debate and to provide somewhat of an overview of the current activity around circular economy and developing more sustainable practices for the lighting industry and beyond. It will reference current development of the new SLL Circular Economy Assessment Method (CEAM) and Technical Memorandum.

As with the previous three sessions, there will be an interactive Q&A, where the audience are invited to ask questions.

This session is part of a 4 part, peer reviewed, CPD series.
