Abstract

La presente invención da a conocer un método para utilizar el material que contiene lignina separado a partir de licor efluente del proceso kraft (licor negro) mediante (a) la acidificación del licor, o una fracción del mismo, a un pH no inferior a 7 dando lugar a la precipitación de partículas sólidas, (b) la separación de las partículas sólidas precipitadas del líquido que las contiene y (c) el sometimiento del material separado como se indica arriba a un proceso de lavado.
