And this isn’t an issue only faced in Europe; these new restrictions leave the US with massive quantities of plastic waste to deal with as well.

Following the Oscars 2018 Best Picture award to Guillermo del Toro’s The Shape of Water, a weird thought probably navigates our minds: what if we had scales instead of skin? No?

Currently, there’s a massive drive toward improving, creating, and manufacturing cheap and safe alternatives to traditional, mammalian-based biomaterials. Biomaterials take many forms: solid inert scaffolds, decellularized ghost organs, hydrogels, pastes, and powders. This is where plants come in, our photosynthetic friends are diverse, adaptable, and cheap to grow – making them perfect candidates for novel biomaterial production.
