- wherein at least a portion of said phenolic resin is produced by a reaction with a phenol substitute;
- wherein said phenol substitute comprises:
- lignin;
- and
- wherein said phenol substitute is a solid residue remaining after extracting lignocellulosic biomass using a two stage process, said two stage process comprising:
- a first stage, wherein the lignocellulosic biomass is treated at a temperature of about 130° C. to about 250° C. for about 0.5 min to about 5 hours;
- and
- a second stage, wherein solids obtained from said first stage are treated at a temperature of about 250° C. to about 450° C. for about 0.1 sec to about 3 min.

A phenol formaldehyde resin comprising:
- a reaction product of phenol and formaldehyde;
- and
- an extender, wherein said extender comprises:
- lignin;
- and
- wherein said extender is a solid residue remaining after extracting lignocellulosic biomass using a two stage process, said two stage process comprising:
- a first stage, wherein the lignocellulosic biomass is treated at a temperature of about 130° C. to about 250° C. for about 0.5 min to about 5 hours;
