I think sci-fi and co greatly underestimate the miracle that is lignin (and by extension cellulose), and coal by extension. Like ok plants just ended up using a compound that make them rigid and helps grow higher, AND it was impervious to any form of decomposition for 60 MILLIONS YEARS ?! They just hit jackpot

What would a world look like if fungi/bacteria had evolved to decompose lignin only 1000 years in ? Would every plant be flat and soft like algae or ferns ? How would the carbon cycle be impacted ? How would have "intelligent life" built its first houses, if not for rigid, abundant material (Clay maybe but i digress) ? How would they make fire ?

Actually i don't know if lignin is that unlikely to happen, all of this came to me in a dream 😄 Also while 60M years of free evolution real estate was certainly beneficial to lignin powerusers, maybe it's just viable anyway without all this time to perfect it

New 3D printing ink uses 70% lignin and recycles with water

Additive manufacturing (AM) methods, such as 3D printing, enable the realization of objects with different geometric properties, by adding materials layer-by-layer to physically replicate a digital model. These methods are now widely used to rapidly create product prototypes, as well as components for vehicles, consumer goods and medical technologies. A particularly effective AM technique, called direct ink writing (DIW), entails the 3D printing of objects at room temperature using inks with various formulations. Most of these inks are based on fossil-derived polymers, materials that are neither recyclable nor biodegradable. Recently introduced lignin-derived inks could be a more sustainable alternative. However, they typically need to be treated at high heat or undergo permanent chemical bonding processes to reliably support 3D printing. This prevents them from being re-utilized after objects are printed, limiting their sustainability.

For tens of millions of years after the first woody trees showed up, wood did not rot easily because lignin is super hard to break down, until white rot fungi evolved the enzymes to digest lignin and make wood truly biodegradable.

Pěna z přírodní gumy a ligninu

Tým odborníků z Národního centra zemědělského a potravinářského výzkumu (CARC) vyvinul novou technologii výroby lehké a odolné pěny z přírodní gumy a ligninu – látky, která je běžnou součástí dřeva a vzniká jako vedlejší produkt při výrobě celulózy. Nový materiál má potenciál nahradit syntetické polymerní pěny, které se obtížně recyklují a zatěžují životní prostředí, včetně tvorby…

Avocado pruning residue can transform into biological additive to stabilize emulsions

Mayonnaise, milk, butter, and various sauces are among the products most associated with the term emulsion. While this technique is widely used in the food industry, it also has a vital role beyond the kitchen. Emulsifying involves homogeneously mixing two liquids that do not blend well naturally, such as oil and water. Although this process may appear simple at first glance, it is essential for the manufacture of numerous products such as paints, cosmetics, and certain pharmaceuticals. The Biopren research group at the University of Cordoba has successfully transformed avocado pruning residues into a valuable resource for making emulsions. Specifically, they have extracted the lignin from avocado—one of the primary components of plant cell walls that acts as a natural glue—and transformed it into an emulsifying agent. This agent acts as a bridge between two liquids that do not mix well, helping to stabilize emulsions and maintain their consistency over time.
