Lignin, the second most abundant polymer, constitutes about 20-25% of dry coffee waste. This branched polymer is sourced sustainably from coffee waste, offering distinct advantages:

Bioenergy: Ideal for biofuels and bioplastics production.

Chemical Industry: A renewable source of phenols and aromatics.

Material Science: Useful in manufacturing carbon fibers, adhesives, insulation.

Agriculture: Functions as a slow-release fertilizer and soil conditioner.

With coffee waste as a sustainable lignin source, its applications across diverse markets are vast.
