In order to reduce the consumption of petroleum when producing lactic acid, some other ecological methods have been considering presently. The improvement of lactic acid production from glucose by solid catalyst such as feldspar was investigated. Nowadays, the conversion of waste into high-value products or particularly fuels has attracted considerable attention. In all high-value products, lactic acid is the main target product in this study because lactic acid is a commodity chemical. The lactic acid yield from this study are 12.37% and 10.84% when using Albite and Potassium feldspar respectively. The catalytic activity of Albite before and after experiments didn't change but Potassium feldspar has changed in the first one. The isometric impregnation treatment was also carried out and the yield of lactic acid improved until 13.24%.
