Episode guide
1:20 – An introduction to Riley and Samsara.
3:25 – The approach has always been with a view to handling a mixed bale of plastic.
4:04 – Enzymatic depolymerisation explained, and its genesis in a discovery in Japan. “The enzyme is like a little Pac-Man.
5:48 - Displacing fossil fuels by harvesting monomers from waste plastic.
7:10 – Enzymes that are designed by computer and new to nature. They can currently handle five types of plastic.
8:58 – How it addresses some of the challenges in scaling up.
10:03 – The only waste that comes out of the process.
11:05 – The low carbon footprint of the process and why this is commercially beneficial.
12:38 – The enzymes like to operate in a temperature range of 45 - 55 degree range and can produce monomers in an hour.
13:20 – The plastic is never melted, which is “fundamentally different” to other recycling approaches.
14:28 – How the enzymes are designed, developed and grown.
15:35 – The timing of their Series A raise and the downturn in venture investment.
16:55 – Why circular plastics hubs are needed and who would be involved.
18:55 – Australia lacks polymer processing capacity, and this presents “enormous sovereign risk.”
20:06 – Innovation and what it means at Samsara.
23:30 – One company is only one part of the solution. Things like redesigning are very important.
25:20 – Why we need to reverse the long-term offshoring trend.
