ReGrained

ReGrained turns brewers’ grain (the stuff left over from making beer) into protein bars. Based in San Francisco, they’re rescuing grain that’d otherwise get tossed and wrapping it in compostable packaging.

Fighting Waste Twice

They’re tackling food waste on both ends - saving spent grain from breweries and using compostable wrappers instead of plastic.

What They Do:

• Rescue brewers’ grain that breweries don’t need
• High-fiber superfood (spent grain is packed with protein and fiber)
• Compostable wrappers that actually break down
• Upcycled Certified (third-party verified)
• Working toward a circular economy

The Packaging

Each bar’s wrapped in compostable film that breaks down in industrial composting facilities. It protects the bar just like plastic but doesn’t stick around forever.

Packaging Details:

• Fully compostable (breaks down completely)
• Plant-based materials, no petroleum plastics
• Needs industrial composting facilities
• Maintains freshness without traditional plastic
• Part of their zero-waste approach

The Bars

Multiple flavors of upcycled grain bars, all using rescued ingredients.

What’s Inside:

• High fiber from spent grain
• Plant-based protein
• Real food ingredients, nothing artificial
• Actually tastes good

Why It Matters

ReGrained’s preventing waste twice - upcycling grain that’d go to landfills and using packaging that composts instead of piling up.

What They’ve Done:

• Rescued tons of grain from waste
• Eliminated plastic with compostable packaging
• Partner with local breweries
• Full ingredient traceability

The Story

Two UC Berkeley grads who cared about food waste started this in 2013. They’re part of a new wave of food companies that don’t treat environmental impact as an afterthought.

San Francisco upcycled grain bars in compostable packaging since 2013.
