Humble Bee Bio is on a mission to create a biodegradable various to plastics by synthesizing the biology of bees. Whereas the New Zealand-based firm remains to be at an early stage — it’s about midway by means of its proof of idea — if Humble Bee is profitable, its bioplastics are prone to make it into the sustainable textiles business.
Humble Bee, which simply raised $3.2 million (NZD $5 million) in convertible notes as a part of its Sequence A, has been finding out the Australian masked bee, a sort of solitary bee that doesn’t make honey, however does make a nesting materials for laying larvae in, which has many plastic-like properties.
“It’s immune to acids and bases. It’s hydrophobic, it’s waterproof, it’s flame retardant, it’s secure as much as 240 levels Celsius,” Ryan Graves, Humble Bee’s chief know-how officer, informed TechCrunch. “The thought is, how will we recreate this?”
The group is utilizing an artificial biology method that includes going into the bee’s genetic code and figuring out the genes and proteins answerable for the nesting materials. Humble Bee has extracted the code and is attempting to recreate it within the laboratory. Subsequent, the corporate will try to synthesize plastic-like supplies, specializing in 4 various kinds of biomaterials that may be become fibers and ending for materials.
Humble Bee is aiming for anyplace from March to June 2023 to show out the idea, at which level the group hopes to scale manufacturing utilizing industrial-scale fermentation.

“There’s a level of exploration nonetheless to go on,” mentioned Graves, “The processes are time-intensive and they’re difficult. Getting going from code to protein is often a 12-month course of, after which we have to scale it as much as get lots of of grams of the stuff out.”
Solely then can Humble Bee even take into consideration a business technique, however Graves mentioned the corporate has already been approached by many textiles firms and different firms that use upholstery. We all know the likes of Airbus, Toyota and Ford try to implement round economic system practices and wish to consider the entire life cycle of their merchandise.
“In the meanwhile, you look inside a automotive, and it’s largely petrochemical-based, so the degradation properties on which can be simply fairly horrendous,” mentioned Graves.
The CTO additionally mentioned style manufacturers have been reaching out to Humble Bee Bio. Environmental sustainability has turn into a precedence for attire firms, significantly in relation to accountable and sustainable sourcing of supplies, in response to a 2019 McKinsey study. That is most evident to date with activewear manufacturers, like The North Face, which used Brewed Protein materials for its Moon Parka, or Adidas, which partnered with Bolt Threads to create a shoe utilizing a mushroom-based materials.
“There’s a load of various firms on this area and that’s one of many issues that has enabled us to maneuver actually quick,” mentioned Graves. “We’re standing on the shoulders of giants which have accomplished loads with spider silks. So that you’ve bought firms like Bolt Threads and Spiber which have huge market capitalizations and are a lot nearer to the business finish. They’ve made proof of idea clothes, which is a complete step above what we’re attempting to do right here.”
With Humble Bee’s most up-to-date elevate, the corporate is aiming to rent one other senior scientist and proceed funding its outsourced R&D. Graves mentioned New Zealand isn’t the most effective place for manufacturing biotech due to some “old-fashioned” genetic engineering legal guidelines, so it appears to be like to nations like Thailand, the U.S., Mexico and Argentina the place there’s current infrastructure within the area.
“One of many beauties of doing biomanufacturing is when you’ve bought the code, the precise engineered cell and principally the recipe for a way you do the fermentation, is that it’s attainable to do a distributed manufacturing mannequin,” mentioned Graves.
The corporate has bought its eye on its subsequent elevate if all goes nicely with proof of idea, and mentioned it’s searching for VCs that concentrate on the impression and local weather area and usually are not averse to danger.
