What in the husk are corn plastics?

You already know that corn can be a solution to so many of our world’s climate challenges, but do you know enough about each renewable opportunity to explain it to your off-the-farm peers? In this article we explore Polylactic Acid (PLA) or corn plastic.



We all know what plastic does to our environment – that’s why for years scientists have been working and researching ways to make biodegradable and eco-friendly products from renewable resources. Replacing petroleum-based plastics with bio-based plastics could reduce industrial greenhouse gas emissions by 25%, according to a 2017 study. Read more benefits below.

How does it work?

Corn plastic is a non-petroleum material made by converting corn into a resin called polylactic acid (PLA). Mostly made from corn because it’s the most affordable and available, however it can be also made from sugarcane, tapioca root, cassava and sugar beet.

What are the benefits of using corn plastic products?

  • Requires 65% less energy to produce than traditional petroleum-based plastics
  • Emits 68% fewer greenhouse gases
  • Renewable Resource – unlike natural gas or crude oil that’s a finite resource, corn is available, functional and renewable
  • Biodegradable – Rather than filling up our landfills, these plastics degrade quickly and can break down even as quick as 45-90 days
  • No toxic fumes – When they’re incinerated, bioplastics don’t emit any toxic fumes
  • FDA-approved – Generally Recognized as Safe polymer and is safe for food contact


Where can I find products for my purchase or for my business?

Currently PLA (corn plastics) are used often in 3-D printing so a common place to find gifts will be where 3-D products are sold. Containers, cups, lids and straws for restaurants or events are also more easily found. Here are just some examples of places you can find corn based plastic products:

How much do you know about the farmers who came before you and the decisions that still shape Illinois agriculture today? That's what University of Illinois student Lyndon Shi set out to explore during his internship with IL Corn . What began as an archival research project became a deeper look at the history of farmer leadership, innovation and advocacy in Illinois. While digging through university archives, Lyndon uncovered an undigitized manuscript from agricultural economist Harold Guither explaining the case for checkoffs. When he mentioned the discovery to IL Corn Director Rod Weinzierl, he got an unexpected response: "Oh yeah, I know him. We worked with him." It was a reminder that agricultural history isn't as distant as it may seem. Lyndon's research connected two eras of the IL Corn Growers Association: the original organization founded in the 1890s and the modern ICGA established in the 1970s. He learned how University of Illinois agriculture dean Eugene Davenport helped organize corn growers and sent professors across the state on "Corn Gospel Trains" to share the latest farming research. One story stood out in particular: the adoption of hybrid corn. Farmers who once judged corn by the appearance of the ear had to shift their focus to yield. Lyndon sees a similar transition today, as farmers increasingly balance yield with profitability amid rising input costs. "Illinois corn farmers are very good at organizing, and they are genuinely very grassroots," Lyndon said. "They've had a much more active role in shaping policy rather than just being on the receiving end." This Summer and Fall, Lyndon will travel to Taiwan on a federal scholarship to study food security. He'll do so with a new appreciation for Illinois agriculture's global connections, including Taiwan's longstanding role as an important trading partner. Watch the full conversation on IL Corn TV to hear Lyndon's research firsthand and discover how Illinois corn's history continues to influence the future.
