lignin is nature’s binder
What is lignin?
Lignin is a naturally occurring organic polymer which is binding the cells and fibers, that constitute the lignified elements of plants, such as straws and wood.
Lignin is nature’s binder that strengthens plants. It is the second most abundant component found in plants and is a renewable carbon source. This natural polymer is embedded within woody plants and constitutes around 20 to 30% of them, alongside cellulose, hemicellulose and phenols.
Lignin can be understood as a complex biopolymer of phenyl propene basic units. In other words, lignin is nature’s binder.
Lignin can be separated into two separate categories, the sulfur bearing and sulfur free ones. The sulfur bearing lignin, also called kraft lignin is mostly obtained as a side stream from wood processing industries.
The sulfur free lignin, such as soda lignin, which has a milder more aromatic smell is obtained from processing various kind of straws and grasses. BMC’s lignin can be classified as a sulfur free soda lignin.
Lignin is an abundant renewable source of carbon.
Lignin is a natural polymer.
