Science

It probably is still legal, but it's not something I've looked for in like a decade. We do have products that use ground kernels, but those aren't good to use on skin--the milling process doesn't produce uniform particles and the pointy bits tend to compromise the barrier skin provides with very small tears.

I completely agree that plastic isn't necessary for good soap, I just like it. I would definitely buy soap made with ecologically responsible plantstic at least once.

More importantly, using safer, scalable, completely biodegradable, algae-based polymers opens up so many more options for single-use products while simultaneously improving environmental quality. Farming algae and seaweeds removes a lot of contaminants from the ocean, like agricultural fertilizer and solid waste runoff. If we can truly scale up ocean farming responsibly, it'll be its own "teal cascade" in which the benefits multiply with each step in the process.

1. Farming algae/seaweed doesn't require the use of inorganic fertilizers when you grow them alongside shellfish like oysters, clams, and scallops

2. Increased protein production through shellfish reduces reliance on agricultural livestock for meat (which is incredibly damaging to the environment)

3. Algae/seaweed can replace fossil carbon in fertilizers and plastics, and reduces cattle methane emissions by 20% or more when added to their regular feed

At each step, we can take more and more petroleum out of the equation just by using methods that are better than sustainable, they actually remediate existing harm.

Plus, I get my scrubby soap back.
