Optimization of methane production from vegetable and fruit peel food waste using response surface methodology / Nurul Shahida Osman

The main objective of this research was to optimize pH and substrate concentration parameters which may affect the methane production by using response surface methodology (RSM) analysis. In this study, food waste (FW) was used as the substrate for methane production. They consisted of fruit peel an...
