Cooking oil was necessary of household to used when processed food ingridients. Waste cooking oil was contained free radicals can potentially oxidize organs. This problem overcome with rice straw and waste of pineapple which waste cooking oil was recycled by them. The utilization cellulose component on rice straw and waste of pineapple  as natural active carbon can helped this problem. The absoption of subtances in waste cooking oil used paper from rice straw which heat together with Na2SO3 solvent while grinding processed with waste of pineapple to made pulp.

Silica Waste cooking oil can be used as a soap or biodiesel. Good soaps or biodiesel should be from oils that have low levels of fatty acids and free radicals. However, waste cooking oil has high free fatty acid and free radical, it is necessary to increase the quality of waste cooking oil. One effort to improve the quality of waste cooking oil can use activated carbon as an adsorbent. Decrease in free radicals in cooking oil can use antioxidants from extract pucuk idat (Cratoxylum glaucum). This study aims to see the effect of extract pucuk idat on the process of improving the quality of waste cooking oil. The process of improvement by adding activated carbon and varying the concentration of ethanol extract pucuk idat. Activated carbon used 10% with variation of extract 0,25%; 0,5% and 0,75%. This process followed by stirring for 15 minutes at 80°C, then soaked for 3 days. Oil quality are identified by the method of determining the levels of free fatty acids and acid numbers. The results of this study indicate that extract pucuk idat in ethanol with 0,75% concentration has the lowest free fatty acid and acid number. Extract pucuk idat can improve the quality of waste cooking oil.

Background: Waste biomass derived reusable heterogeneous acid based catalysts are more suitable to overcome the problems associated with homogeneous catalysts. The use of agricultural biomass as catalyst for transesterification process is more economical and it reduces the overall production cost of biodiesel. The identification of an appropriate suitable catalyst for effective transesterification will be a landmark in biofuel sector Objective: In the present investigation, waste wood biomass was used to prepare a low cost sulfonated solid acid catalyst for the production of biodiesel using waste cooking oil. Methods: The pretreated wood biomass was first calcined then sulfonated with H2SO4. The catalyst was characterized by various analyses such as, Fourier-transform infrared spectroscopy (FTIR), Scanning Electron Microscopy (SEM), Energy Dispersive X-Ray Spectroscopy (EDS) and X-ray diffraction (XRD). The central composite design (CCD) based response surface methodology (RSM) was applied to study the influence of individual process variables such as temperature, catalyst load, methanol to oil molar ration and reaction time on biodiesel yield. Results: The obtained optimized conditions are as follows: temperature (165 ˚C), catalyst loading (1.625 wt%), methanol to oil molar ratio (15:1) and reaction time (143 min) with a maximum biodiesel yield of 95 %. The Gas chromatographymass spectrometry (GC-MS) analysis of biodiesel produced from waste cooking oil was showed that it has a mixture of both monounsaturated and saturated methyl esters. Conclusion: Thus the waste wood biomass derived heterogeneous catalyst for the transesterification process of waste cooking oil can be applied for sustainable biodiesel production by adding an additional value for the waste materials and also eliminating the disposable problem of waste oils.

At the present moment worldwide waning fossil fuel resources as well as the tendency for developing new renewable biofuels have shifted the interest of the society towards finding novel alternative fuel sources. Biofuels have been put forward as one of a range of alternatives with lower emissions and a higher degree of fuel security and gives potential opportunities for rural and regional communities. Biodiesel has a great potential as an alternative diesel fuel. In this work, biodiesel was prepared from waste cooking oil it was converted into biodiesel through single step transesterification. Methanol with Potassium hydroxide as a catalyst was used for the transesterification process. The biodiesel was characterized by its fuel properties including acid value, cloud and pour points, water content, sediments, oxidation stability, carbon residue, flash point, kinematic viscosity, density according to IS: 15607-05 standards. The viscosity of the waste cooking oil biodiesel was found to be 4.05 mm2/sec at 400C. Flash point was found to be 1280C, water and sediment was 236mg/kg, 0 % respectively, carbon residue was 0.017%, total acid value was 0.2 mgKOH/g, cloud point was 40C and pour point was 120C. The results showed that one step transesterification was better and resulted in higher yield and better fuel properties. The research demonstrated that biodiesel obtained under optimum conditions from waste cooking oil was of good quality and could be used as a diesel fuel.
