Biopolymers in industrial phenolic-resin plant
Biopolymers based phenolic-resin
- Introduction to Natural Binder Lignin
- Use of Lignin BioResins to replace Phenol in phenolic-resin plant
The inherent toxicity of existing chemical raw materials and the growing concern about the environmental impact of fossil-based raw material has encouraged manufacturers to look for natural alternatives.
The Natural Binder LIGNIN constitutes 30% of any tree & acts as the natural glue that holds cellulose and hemicellulose. Lignin is a macromolecule that has phenolic characteristics and replaces a very common ingredient of resins called Phenol; Advance formulation has been developed to manufacture the #BioRESIN for wood panels which effectively reduces the harmful emissions in our homes
Commercial Production of phenolic resin in which much of the phenol is replaced by lignin is successful.
Lignin is a class of complex organic polymers that form important structural materials in the support tissues of vascular plants and some algae. Lignins are particularly important in the formation of cell walls, especially in wood and bark, because they lend rigidity and do not rot easily. Chemically, kraft lignins are cross-linked phenolic polymers.
Apart from cellulose and chitin, lignin is the most frequently occurring polymer in nature – and the only one to contain many of the aromatic compounds that are normally recovered from mineral oil.
Every year the world produces around 50 million tonnes of lignin as a by-product of the paper industry. The material potential of lignin, which in this case is generated as black liquor, has as yet been very little realized: 98 percent of this material is currently incinerated.
