Assessing A Byproduct Of The Cbd Ethanol Extraction Process For Potential As A Wood Finishing Product, Avani M. Flanagan Jan 2023

Assessing A Byproduct Of The Cbd Ethanol Extraction Process For Potential As A Wood Finishing Product, Avani M. Flanagan

Masters Theses

Developments in regulations concerning the use of CBD products as therapeutic remedies have allowed the global cannabidiol (CBD) market to take off within the past five years. Despite producers of CBD oil wanting to optimize their methods and increase product yields, several waste streams still exist. During the winterization phase of the ethanol extraction process, CBD oil is cooled and filtered so the fats, waxes, and lipids from the Cannabis sativa plant can coagulate and be removed, creating a purer oil with higher potency but contributing to the 58% (crude weight) total loss that occurs throughout the process. The removed …


Degumming Of Hemp Fibers Using Combined Microwave Energy And Deep Eutectic Solvent, Bulbul Ahmed Jul 2021

Degumming Of Hemp Fibers Using Combined Microwave Energy And Deep Eutectic Solvent, Bulbul Ahmed

LSU Master's Theses

Hemp is considered as one of the sustainable agricultural fiber materials. Degumming or surface modification of hemp bast is needed to produce single fibers for ensuing textile and industrial applications. The traditional degumming process necessitates a high amount of alkali, which causes detrimental environmental pollution. This study offers a new method to degum hemp fibers with reduced use of harmful alkali and precious water resources. In this work, hemp bast fibers were degummed by using combined microwave energy and deep eutectic solvent (DES). The properties of hemp fibers manufactured by this method were investigated and compared with the traditional alkali …
