Genecis says its plastics biodegrade in about a year.
Plastics have revolutionized manufacturing, but they’re still terrible for the environment.
Manufacturing plastics is an energy-intensive slog that ends in mountains of toxic industrial waste and greenhouse gas emissions. And then the plastic itself that we use ends up sitting in a garbage heap for thousands of years before it biodegrades.
Scientists have spent years investigating ways to manufacture plastics without ruining the planet, and a Toronto biotech startup called Genecis says it's found a good answer: factories where vats of bacteria digest food waste and use it to form biodegradable plastic in their tiny microbial guts.
The plastic-pooping bacteria stand to clean up several kinds of pollution while churning out usable materials, according to Genecis.
The plastic that the little buggers produce isn’t anything new. It’s called PHA and it’s used in anything that needs to biodegrade quickly, like those self-dissolving stitches. What’s new here is that food waste is much cheaper than the raw materials that usually go into plastics, leading Genecis to suspect it can make the same plastics for 40 percent less cost.
There are a lot of buzzworthy new alternative materials out there, but with a clear environmental and financial benefit, it’s possible these little bacteria factories might be here to stay.
