Abstract
Lignocellulosic waste, such as date palm seeds, is treated with industrial waste such as rejected brine solution waste from a water treatment desalination plant to break down lignin and isolate and recover cellulose. Such a method is more cost effective and less toxic than other current and prior methods. Such a method concurrently solves two problems—usage of lignocellulose waste and usage of brine solution waste from a desalination treatment plant—to isolate and recover biocompatible, biodegradable versatile cellulose.
Claims15
A method for the removal of lignin from a lignocellulose material to extract cellulose from the lignocellulose material, the method comprising:
- providing a lignocellulose material;
- crushing the lignocellulose material;
- providing rejected brine solution waste from a water treatment desalination plant;
- mixing the crushed lignocellulose material with the rejected brine solution waste while heating to obtain a mixture;
- and
- filtering the mixture to obtain the cellulose;
- wherein the rejected brine solution comprises a sodium ion concentration greater than 20,000 ppm, a chlorine concentration greater than 45,000 ppm, a magnesium ion concentration greater than 2,500 ppm, and a calcium ion concentration greater than 1,000 ppm.
