Total recovery of fermentable sugar from lignocellulosic biomass has foremost problem for liquid biofuel production. Several pretreatment methods have been tried, however use of ionic liquids is one of promising method then others, but it also has less efficiency. Hence a method was developed for pretreatment of sugarcane leaves using ionic liquid EmimAc (1-ethyl-3-methylimidazolium acetate), aqueous ammonia and a combination of both.

The unstable composition and properties of pollutants, together with very high concentration of pollutants such as ammonia nitrogen, COD and especially persistent compounds such as polyaromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), heavy metals, so leachate is the object that is very difficult to deal with. In fact, after a pretreatment as electrocoagulation, over 73 % of COD has been treated from Nam Son landfill leachate, however the output value of COD still exceeds the QCVN 40:2011/BTNMT, column B.
