Corn stover has been identified as a key resource in the transition from petrochemicals to
sustainably sourced energy and materials; however, the as-recovered lignin from alkaline …

A two-stage alkaline-oxidative pretreatment of hybrid poplar was investigated at scale (20 L
reactor volume) with the goal of understanding how reaction conditions as well as interstage …

Polyvinyl chloride (PVC) and polyethylene terephthalate (PET) contribute significantly to
global plastic waste, with only 9% recycled in recent years. In this work, these plastic wastes …

Technical lignins are relatively heterogeneous and structurally not fully understood, which
hinders their commercialization. This study involves the precipitation fractionation of …

In order to effectively practice the Aqueous Lignin Purification with Hot Agents (ALPHA)
process for lignin purification and fractionation, the temperatures and feed compositions …

A unique acidification and heating process has been discovered that enables the recovery
of high-purity lignin from dilute alkaline pretreatment liquors without filtration or …

In recent years, there have been extensive efforts to replace fossil-fuel-based raw materials
with bio-based materials in flexible polyurethane (PU) foams. Lignin, a natural polyol …

This research investigates the extraction and modification of cellulose and lignin from
