“…Therefore, F/I ratio of 2:1 produced more methane than F/I ratio of 1:1. Increasing in methane yield by co-digestion has been attributed to improve nutrient balance, mitigate toxicant levels or enhance microbial activity [20]. Solid waste in the palm oil mill such as decanter cake, empty fruit bunch and palm kernel shell are not utilize, due to its composition are difficult to degrade by methanogenic bacteria [18].…”

A novel micro-solid oxide fuel cell (µ-SOFC), with a rectangular saw-tooth shape, was designed with a 50 wt% BYCF + 50 wt% GDC 10 cathode and a 60 wt% NiO + 40 wt% GDC 10 anode deposited on a GDC 10 electrolyte substrate by the spray pyrolysis technique. µ-SOFC receives methane only (CH 4) as fuel gas from one side. The fuel gas was applied at a flow rate of 0.2 l min −1. The power density obtained was 1.0 µW at 800 • C. Voltage levels generated by the µ-SOFC at 40-99.99% CH 4 was highly accurate representing the quantity of CH 4. Low accuracy was observed at 10-30% of CH 4. Therefore, µ-SOFC is an application of SOFC technology to be a sensor for economically detecting CH 4 in a biogas system, while being capable of operating in humid conditions at high temperatures.

“…Furthermore, the utilization of this abundantly available biomass to produces bioethanol can also help in solving both energy security and also waste management problem. Fruit wastes is a type of lignocellulosic biomass; a type of biomass whose major compositions are cellulose, hemicellulos, and lignin, in which the compositions of these three materials play an important role in determining the efficiency of the process where the biomass is being utilized [4].…”

Bio-ethanol, a type of biofuel, is known as renewable energy source as it is derived from biomass as its raw material. Biomass can be found in abundance and sustainable i.e. sources are available continuously, unlike the currently used conventional fossil fuels where these sources are limited and depleting. In this study, biomass from fruit waste, banana peels, were utilized to produce bio-ethanol via hydrolysis and fermentation process. Banana peels, a lignocellulosic biomass, possesses compositions which favour these processes, where the banana peels are rich in cellulose content and low in lignin content. Mechanical pre-treatment of the banana peels was conducted to further ease the hydrolysis process by reducing the particle size of the biomass. Hydrolysis was carried out for 24 hours at 50ºC at different pH using sulfuric acid H2SO4 acid and sodium hydroxide NaOH as the base, to study the effect of pH on the hydrolysis process and hence the final bio-ethanol production, in terms of concentration. Fermentation of the hydrolysis products were carried out using glucose-yeast broth for 4 days at temperature of 35ºC. Water content in the bio-ethanol product from fermentation process was separated using rotary evaporator, prior to ethanol analysis using Gas Chromatography (GC-MS). Concentration of ethanol was found to be the highest at acidic pH conditions; pH 4 to 6. Lowest ethanol concentration was recorded at higher pH values, indicating alkaline conditions do not favour the hydrolysis process.
