Edible plastic? BlueCitizen Lori Goff from Outlander Materials transforms the waste stream of beer brewer VET & LAZY into ‘Bitables’; an alternative for single use plastics. Bitables are compostable, high in fiber and vegan friendly. They are completely edible and don’t harm nature- even fish can eat them.
The idea was born a few years ago when Lori received a beer brewing kit as a birthday gift. “I was brewing beer in my kitchen and started to take a more serious look at the amount of waste produced during the beer brewing process. And then I thought: there’s definitely cool stuff I can make out of this.”
From beer to Bitables
And so she did. She settled in BlueCity Lab, started experimenting and soon got in touch with VET & LAZY. “To create one liter of beer you need seven liters of fresh water.” she states. The remaining six liters, referred to as brewery effluent, is normally being wasted. But not on Lori’s watch. “I use the waste stream that is produced during the beer brewing process and expose it to a different kind of fermentation process. As a result, I produce a material that can be developed into a new alternative to plastics.”
The first thing Lori created with this new material were candy wrappers, but it can be used to replace multiple types of single use plastics. “There are different ways of processing the brewery effluent and there are a lot of variables I can change that will affect the resulting material. This makes the material suitable for multiple applications.” she says.
In addition to this, Lori’s Bitables have multiple other advantages that could possibly make this material the ultimate alternative to single use plastics. They are compostable, edible, vegan, transparent and it’s possible to add flavours or scents if desired. Last but not least, Lori says: “Bitables have almost no calories but they do contain a lot of fiber, which means they are actually good for you!”
From Nebraska to Rotterdam
It’s no surprise that an innovative idea like this precisely popped into Lori’s head. “I’ve always been very environmentally focused,” she explains, “I used to watch this cartoon on TV when I was a kid called Captain Planet. It’s about a superhero who saves the environment time and time again. This image stuck with me, even now.”
She decided to pursue a degree in biotechnology. “I went into biotech because I wanted to have the scientific background to bring environmental projects to fruition and give waste a functional use again.” After graduation, Lori moved from Nebraska (United States) to the Netherlands to be with her boyfriend, and not long after she found herself brewing beer in the kitchen we started this story with.
From there, the road to BlueCity Lab was easy. It was a matter of one call that ensured Lori of her own Lab space. Which she is very grateful for: “BlueCity Lab is a living environment of everything I’ve always wanted. It’s about circularity, minimising waste and creating functional startups.” she says, “It’s about providing solutions to existing problems, which is exactly what I want to do.”
Hitting the shelves
When you’re reading this you might wonder why it is you haven’t found these Bitables in your local supermarket yet. “I’m currently working on a business case and talking to various companies about projects and funding,” Lori explains, “I expect that in about 4 and a half years there will be 3 to 4 vegetables on the Albert Heijn shelves wrapped in Bitables!”
And Lori’s mission doesn’t end there. She hopes to provide a solution to the plastic waste problem without having to eliminate packaging all together. “We do need packaging,” she states, “because food travels from one place to another and without the protection of packaging, we would have a lot more food waste. To me it just doesn’t make sense that you have food that only lasts for a few moments and a plastic wrapper that lasts an eternity.” And thus, Lori concludes: “I hope that one day Bitables will replace single use plastics in the supermarket, from fresh fruits and vegetables wrappers, to cookie and candy packaging!”
