Comparison of treatments for cellulose pulp from agro-industrial wastes from the Amazon region

Agroindustrial waste (AIW) is a potential source of cellulose, which can be obtained through different treatments. In this study, we evaluated four delignification treatments (10% sodium hydroxide, 50% ethanol, distilled water, and 25% Mohr's salt) to obtain cellulose pulp from Amazonian AIWs (banana peel, cassava sugarcane bagasse, rice husk). Our results showed that hydroxide treatment had the highest lignin removal increased content, while salt lowest yield removal. Banana peel husk yield, lowest. Distilled water at medium temperature similar ethanol findings suggest have great as these economical, simple, eco-friendly used high-purity AIWs.
