Session 3: How the Circular Economy Improves Sustainability

← Back to Schedule

Rather than produce, use, and discard products, today’s economy must save resources by producing, using, reprocessing, and reusing resources, then creating new products in a Circular Economy.

Anica Landreneau, Director of Sustainable Design, HOK Architects, will briefly define the term “Circular Economy,” so that we may apply the term clearly to various sectors and businesses during the panel.

Panelists in specific sectors of the Circular Economy will then describe how this resource-conserving model applies to (1) the food recycling industry, as set forth by Walker Lunn, Founder of EnviRelation, a hotel food waste composting company, and a serial entrepreneur, (2) the battery recycling industry, as told by Eric Lundgren of Big Battery, (3) the renewable energy industry, exposited by renewable energy lawyer Carolyn Elefant, then (4) back to Anica Landreneau for the Circular dimensions of the construction and real estate industries. There will be lively discussion among the panelists from the different sectors, which will utilize the fact patterns of different industries and companies to refine and advance the meaning of “Circular Economy” in theory and practice.
