This is potentially very exciting, but companies have also talked about producing cheap and sustainable aviation fuel from algae for at least 15 years. They talk about scaling up from "several tonnes" of algae 2 or 3 years from now. It seems a very long way from being a replacement for anything yet, let alone plastic.

We should all be desperate for this to work on a massive scale. Congratulations to the researchers who have made the first steps.

We need to eat it, not turn it into bags soon.

There are a couple of Silicon Valley startups working on this. The biggest issue is time. The “plastic” breaks down after about 6-8 weeks. So even though the product is about the same cost as regular plastic, it’s shelf life is much much shorter - ultimately increasing the cost if they have to throw it away before usage.

Isn't that really the point, though? That it doesn't last? There's probably a need to improve that shelf life, but ultimately I don't see a way to get out of the cost for storage and recycling being higher, but that's because it actually uncovering some of the hidden costs of environmental damage of plastics.

This is great news! I was on vacation in the caribbean last year and there was so much sargassum seaweed floating on the water that we didn’t want to swim!

Maybe they can turn algae into another one of those amazing batteries we keep hearing about. You know, the ones that charge instantly, fit in your pocket, and hold a charge large enough to power your house for 10 years.

Somebody should focus on the algae in Lake Erie for this project.

Kind of get where you come from, the issue comes from excess of nutrients in the water being washed out from farm terrains, but the issue is that the excess of algae needs to be fixed. Whether it's by organizations, or by the producers trying to fix their own mess

I've always wanted to see human ability to over harvest up against something invasive or over populous.

If it gets scaled up to commercial and ubiquitous use, a good fleet of commercial ships could theoretically clean huge swaths of water.

It would be great if these products wouldn't eventually decompose into carbon dioxide, methane, etc. that contribute to climate change. Algae is great at capturing carbon, but we have to make sure it doesn't reenter the atmosphere

I really hope she gets rich in this! That will motivate others to try and to the same!

That sounds absolutely awesome if used for food packaging, like replacing all those plastic clam shells and soda can ties. At first I was worried this was going to be like when they foolishly replaced wiring insulation with soy and was imagining the rodents salivating over newly edible algae car parts and electrical boxes after they finished off the wires.

It's not the point but it's definitely a factor. Imagine your warehouse having some liquid all over the floor and a good chunk of the product because this algae plastic degraded early. If it hurts the bottom line, companies won't switch easily, which means this tech won't have much of an impact.

If it even so much as just "doesn't hurt the bottom line" companies will gladly switch and tout their eco friendly products.

I’m a kelp farmer and I must say there’s a lot of noise and very little to show from bioplastic companies that I talk to.

I think there may be some very real potential on the biofuels front but scaling up will take some awesome infrastructure projects the likes of which we can’t easily imagine for, including it’s effects on ocean dwellers and oceanic nutrient flows.

We're probably going to need to add a petroleum tax and/or fossil fuel tax to make up for the hidden costs of continuing to use oil-based plastics and fossil fuels. Eliminating subsidies for oil and coal companies would also help.

A faster decomp than plastic is absolutely a win but less than a year would make it almost entirely worthless. By the time it gets from the factory to the consumer it will probably already be falling apart

Isn't the primary problem lack of algae for a mass production scale and low density per unit of volume you need to farm it.

There are countless technologies for alternatives, but they all lack the means to scale up.

A ski (and now snowboard) company locally here in SLC, WNDR Alpine, replaces petroleum with algae in their core and sidewall. Sick products.

Biofuels from algae were a potential, but then oil prices shot back down. These companies decided the market was too volatile but used the knowledge they gained to use algae for plastics, neutraceuticals, alternative meat, etc

In my mind the idea is simply to move away from coal, oil and gas as our primary sources of energy and materials. They don't need to go away completely as long as we develop enough methods and means to offset their use and start undoing the damage we've already done.
