Rich Riley—Co-CEO, Origin Materials

Jill Wagner

Welcome to Cheddar’s Opening Bell. The fight against climate change has reached the highest levels of our national conversation, but it’s going to need more than just talking about the issue to actually fix the problem. The solution takes action and resources.

To that end, the company Origin Materials is working to facilitate the economic change to a more sustainable model; the company also on a verge of going public via a SPAC. And joining us to discuss is Origin Materials co-CEO, Rich Riley. Rich, great to have you on. Tell us a bit more about the philosophy behind Origin Materials and what your company is trying to accomplish.

Rich Riley

Yes. Thanks for having me, Jill. We’ve spent 12 years developing a disruptive one of a kind technology that converts sustainable plant-based feedstocks into a wide range of materials, including plastics. And the game changer is really that the materials are carbon negative, cost competitive with petroleum products, and fully recyclable. So, we’re trying to help companies meet their net zero carbon pledges.

Jill Wagner

So, what prompted your decision to go public? And why did you decide to do it via a SPAC instead of a traditional IPO?

Rich Riley

So, we’ve had a lot of investors tell us that this is the kind of deal that a SPAC was meant for, a proven disruptive technology, incredible customer demand, and a need for a relatively large amount of capital to build the facilities to satisfy that demand. And so, the SPAC process let’s us raise about $900 million very quickly and get to market and help our customers meet their net zero goals.

Jill Wagner

So, how does it work? Do specific companies like toymakers, I know that your material can be used--it’s pretty diverse. It could be used for things like toys. Do they come to you and ask for the technology? What is your relationship with consumer producers—consumer product producers?

Rich Riley

Yes. So, we have a wide range of relationships with companies around the world who are seeking to transition their supply chains from fossil-based materials to sustainable materials and reduce their carbon footprints. And so, we work with companies like Nestle, Danone, and Pepsi, who have extensively tested our materials and are investors in the company, and are having conversations with a wide range of companies from automotive to toys to textiles. It’s a trillion dollars of materials that need to make this transition, and we’re working with a lot of companies to make that happen.

Jill Wagner

It feels like every day we’re reporting on another company saying that they want to go carbon neutral, but the years that the goal is really vary. It’s anything from 2027, some say by 2050. Do you think that private companies are doing enough? And do you think that the government really needs to be behind this?

Rich Riley

So, we’ve seen a lot of action from governments. The Paris Climate Accord is a big one that calls for removing over 40 gigatons of annual CO2 emissions. So, governments around the world have acknowledged this and are taking action. There’s been a tsunami of corporate net zero pledges, as you mentioned.

And as they go on that net zero journey, they quickly realize that renewable power and transportation are only about half of the emissions, and the other half is from products that are made and materials. And that’s where companies like us come in to help them decarbonize their supply chain, which is critical to help them meet those goals.

Jill Wagner

Origin Materials of course tackling this enormous problem of carbon in our modern world. So, depending on what estimate you go by, anywhere from 100 billion to 1 trillion tons of carbon need to be removed. So, again, is this something it’s just going to be private companies working with the governments to do this? Because it seems like it’s a priority or important to most people now, but how do we fix it?

Rich Riley

Yes. So, I think it’s going to be an all of the above type approach. So, governments are taking action, setting their own net zero pledges. The EU and recently Japan have set those kind of goals and are implementing various incentives and penalties to encourage companies and everyone to go carbon neutral.

And companies get it, and CEOs are realizing that their employees and their shareholders and their customers want them to be mindful of their impact on the climate and to get to net zero. And that’s why you see these incredible announcements. Almost every week there’s a new one, and some are even moving their original dates in and truly working aggressively to meet these goals. So, it’s going to take government, public companies, private companies, and really consumers and all of us to make this happen.

Jill Wagner

All right. Well, congratulations on going public and thank you so much for coming on. Origin Materials co-CEO Rich Riley, really appreciate your time.
