Driven by the need of growing to a more sustainable and environmentally friendly future, this research is started by mixing in-house produced biorenewable polymers (BP) from waste cooking oil with the standard low density polyethylene (LDPE) and high density polyethylene (HDPE) via melt-mixing at low ratios. These mixtures are then compounded via injection molding to produce tensile samples. By using the quality of individual compounds injected, the parameters obtained for all ratios of LDPE/BP were the same with neat LDPE whereas some adjustments were required for the HDPE/BP compounds. The corresponding mechanical behaviors of each ratio were also examined and the results showed that both tensile strength and strain of the LDPE/BP were better than neat LDPE. On the other hand, increasing the BP content in HDPE/BP will increase the toughness of the compound if compared to neat HDPE. Therefore, not only does the presence of BP provide renewable properties, but it also improves the mechanical properties. Moreover, the processing temperature and composition of BP will both influence the quality and mechanical behavior of the product made. Thus, this study may aid any intention on processing these in-house produced polymers by injection molding.

This research is started by mixing in-house produced sustainable polymers (SP) from waste cooking oil with the standard low density polyethylene (LDPE) via melt-mixing at low ratios. These mixtures are then compounded via injection molding to produce tensile samples according to ISO 527 (5A). The parameters used in injection molding were initially set to follow the parameters of neat LDPE. Fortunately, by using the quality of individual compounds injected, the parameters obtained for all ratios were the same with neat LDPE. The corresponding mechanical behaviors of each ratio were also examined and the results showed that both tensile strength and strain of the LDPE/SP were better than neat LDPE. Therefore, not only does the presence of SP provide biodegradable properties, but it also improves the mechanical properties. It was concluded that the processing temperature and composition of SP will both influence the quality and mechanical behavior of the product made. This study may aid any intention on processing these in-house produced polymers by injection molding.

Objectives: This research discuss the simulation of the bad bitumen which gives a penetration out of the specification limit and Study the effect of crumb rubber on the performance of asphalt mixture in case of low penetration grade and waste cooking oil in case of high penetration grade. Presentation of Case: Determination of the permissible limits of the diffraction in the degree of penetration for Suez Bitumen and Alexandria bitumen. Methodology: 14 asphalt mixtures are designed by using two types of bitumen (Alexandria bitumen and Suez bitumen). By using crumb rubber powder (C.R.P) with contents (6%, 8% and 10%) to decrease penetration for Alex bitumen by (59, 56 and 53) respectively. Then  (-C.R.P-) was added with ratios (5%, 6.5% and 8%) to decrease penetration for Suez bitumen by (59, 56 and 53) respectively. after that waste cooking oil was added with different percentages (0.3%, 0.5% and 1%) for each bitumen type to increase penetration by (71, 74 and 77) respectively.  Marshall Test was implemented for all asphalt mixtures to determine stability value and flow. The ITS Test was performed for all mixtures to determine tensile properties for mixtures. Results: The results were showed important conclusions for using bitumen with penetration grades (60/70) with increase or decrease in penetration by 7.  Conclusion: This study recommends using (C.R.P) with ratios (10% and 5%) from bitumen weight for Alex and Suez bitumen respectively for achieving 53, 59 penetration to obtain 29% increase of stability value and  23.64% for Alex and Suez bitumen mixture  respectively.

Some research projects have studied full recycling of reclaimed asphalt pavement (RAP). Several additives have been used to rejuvenate the RAP’s aged bitumen. The authors previously studied full recycling of RAP rejuvenated with waste cooking oil (WCO). The asphalt concrete (AC) manufactured revealed good mechanical behaviour except for rutting resistance. Therefore, they decided to also include in the asphalt mixtures low density polyethylene (LDPE) from urban waste as a low-cost polymer to improve that weak point and verify if this technique was feasible and with potential as a pavement material. A laboratory plan was conceived to evaluate the mechanical performance of two rejuvenated ACs with WCO and LDPE. Stiffness, water sensitivity, resistance to rutting and fatigue cracking were evaluated. The results showed that, despite some empirical parameters usually indicated in current specifications not being met, the performance of the studied asphalt mixtures was adequate and, thus, there are good expectations about the future use of these solutions in real pavements, particularly for low and intermediate traffic levels. Based on a global analysis of the performance observed, the main conclusion was that full recycling of AC with WCO and LDPE is feasible, and the score obtained was higher than that of a conventional AC used for comparison.

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.
