Paper pulp production leaves lignin as by-product, at least for some processes. Otherwise it is burned as fuel.
Biodegradable plastic bags are made from this (I think) and they have been in stores for many years; for example in fruit/vegetables sections. They are noticeably "less good" than old-style PE bags.
- troyvit 2y agoReading the article (which isn't that good) it seems that Lignin's goal isn't compostability but rather oil independence. On Lignin's site they say: "RENOL® is proven to be very stable during recycling, keeping its properties during many recycling cycles. RENOL® slows down the breakdown of PE and ABS in recycling processes." So I think they are looking more at a model of using a substance that is usually burned to make a plastic that can be reused and yes, as somebody else said, fill our ocean with more plastic. It's a little hard to tell though, lignin.se has some dead links, which doesn't seem too smart for a product launch.
