The present invention provides novel and improved processes for treating a lignocellulosic biomass or technical lignin using ionic liquids to obtain lignin breakdown products and polysaccharide biomass components. Recycling of ionic liquids can be included in the methods of the invention.

Renewable aromatics from lignocellulosic lignin

A concrete mixture is provided. The mixture includes cement powder, a plant biomaterial in a solid form, wherein the plant biomaterial does not comprise ash, and concrete aggregate, wherein a ratio of cement powder to the biomaterial ranges from 10:1 to 100:1. Methods of controlling concrete setting by adding a plant biomaterial in a solid form to a concrete mixture are also provided.

Biomass waste materials as a set-retardation agent in cement or concrete

Methods of converting lignocellulosic derivatives form 5-hydroxymethyl furfural (HMF) in ionic liquids are provided herein. Glucose is enzymatically converted to fructose by isomerization with glucose isomerase and a borate salt. Conversion of fructose to HMF includes dehydration of fructose using ionic liquids or ionic liquids with an acid catalyst to achieve high yield of HMF.
