A lot of vegan leather is plant based.
Pineapple and cork are two big ones.
https://en.wikipedia.org/wiki/Pi%C3%B1atex
Still plastic, unfortunately.
Cork is definitely a cleaner alternative, but I don't know how durable it is in "leather" form.
Cork is cork, a lovely and great material with a ton of applications, but it's not leather. It will not last as long and won't withstand the abuse that leather can.
Piñatex (Spanish pronunciation: [piɲaˈteks]) is the trade name for a non-biodegradable leather alternative made from cellulose fibres extracted from pineapple leaves, PLA (polylactic acid), and petroleum-based resin
So, basically when the fibers decompose, it leaves PLA and petroleum byproducts.
PLA, is a plastic. A bioplastic, sure, but contrary to popular belief, it will not degrade unless done under industrial composting conditions. It will not degrade in your backyard compost pile, and will break into microplastics.
