Acid Hydrolysis of Waste Paper to Glucose


 

Waste paper stands for the major biodegradable organic fraction of most municipal waste. The potential of acid hydrolysis of waste paper for glucose production was investigated in this current work. This was carried out in two stages which involved the pretreatment of two samples (Computer printout and Newspaper), which was accompanied by first shredding the paper into pulp. Acid hydrolysis of waste paper was optimized to maximum glucose conversion, with a nitric acid concentration of 5.0 mL at 121 °C in an autoclave. The obtained results showed maximum percentage reducing sugar yield for 5 % w/v waste paper with 1 % v/v nitric acid at 72 h was 24.93. The obtained result showed that the maximum percentage reducing sugar yield for 5 % w/v waste paper with 5 % nitric acid at 72 h was17.59. The obtained results showed that the maximum percentage reducing sugar yield for 5 % w/v waste paper with 10 % v/v nitric acid at 72 h was 18.1. This research of acid hydrolysis is a promising method to improve waste paper conversion to glucose in order to control environmental pollution.

Abstract


Waste paper stands for the major biodegradable organic fraction of most municipal waste. The potential of acid hydrolysis of waste paper for glucose production was investigated in this current work. This was carried out in two stages which involved the pretreatment of two samples (Computer printout and Newspaper), which was accompanied by first shredding the paper into pulp. Acid hydrolysis of waste paper was optimized to maximum glucose conversion, with a nitric acid concentration of 5.0 mL at 121 °C in an autoclave. The obtained results showed maximum percentage reducing sugar yield for 5 % w/v waste paper with 1 % v/v nitric acid at 72 h was 24.93. The obtained result showed that the maximum percentage reducing sugar yield for 5 % w/v waste paper with 5 % nitric acid at 72 h was17.59. The obtained results showed that the maximum percentage reducing sugar yield for 5 % w/v waste paper with 10 % v/v nitric acid at 72 h was 18.1. This research of acid hydrolysis is a promising method to improve waste paper conversion to glucose in order to control environmental pollution.
