The effect of acid and alkali pre-treatment methods on pineapple peel waste for bio-ethanol production

Pretreatment processes are key technologies for producing fermentable sugars from lignocelluloses biomass. In the present work, two pretreatment techniques using diluted acid (H2SO4) and diluted alkali (NaOH) have been compared for producing bio-ethanol from pineapple peel waste (PPW). Treatment’s p...
