Over exploitation of non-renewable energy reserves will lead to increase in price of petroleum *** there is a need for suitable and sustainable substitutes(renewable resource) for conventional *** this study,an efficient and environmental friendly method for production of bio-diesel from Pongamia(Karanja) oil has been developed using a solar *** the experimental study,the maximum temperature attained by the pongamia oil during the transesterification process was 64.1℃.The transesterification reaction was studied by varying different parameters such as reactant flow rate(5-20 L·h^(-1)),stirring speed(150-450 r·min^(-1)),catalyst mass loading(0.5%-2%) and methanol to oil ratio(3:1 to15:1).The maximum biodiesel yield was 83.11% at a flow rate of 5 L·h^(-1),stirring speed of 350 r·min^(-1),a methanol to oil ratio of 15:1,catalyst mass loading of 1% and reaction time of 270 *** physical and chemical properties of biodiesel was analyzed as per American Society for Testing Materials(ASTM) standards and it had density of 938 kg·m^(-3),viscosity(28.7×10^(-6) m~2·s^(-1)),acid value(9.45 mg KOH·(g oil)^(-1))and flash point(215℃).The energy efficiency of solar heating process was determined by comparing the net energy ratio of direct heating process and solar heating *** solar heating the net energy ratio(NER) was found to be 31.85 against 5.73 for direct ***,net energy efficiency index was calculated for 10 kg production scale and was found to be increasing when scaled up which means that the solar heating process is more effective even in scaled up production.

Hydrothermal liquefaction(HTL)is a promising method for sustainable waste management and renewable energy production,converting mixed feedstocks into bio-crude,a precursor to various biofuels.A study focused on mixed residential waste(MRW)as an HTL feedstock investigated temperature ranges(280e360℃)and residence times(30e90 min),achieving a maximum bio-crude yield of 39.16%at 340℃and 75 ***,a thorough investigation of the synergistic relationships between all subcomponents of the MRW feedstock was conducted and concluded that the mixed waste(MW)feedstock samples containing a higher proportion of food and plastic wastes and MRW sample presented with a coliquefaction percentage(CE)of around 60%and 107%respectively for production of bio ***,solvents such as ethanol,glycerol and aqueous phase(AQ)were tested for their potential as hydrothermal mediums and found that bio crude yield of 46.19%was obtained in case of AQ phase ***,the quantitative and qualitative effect of usage of four different catalysts were tested individually and in combination with AQ phase recirculation and found that,although individually nanoporous ZnO and diatomaceous earth(DE)yielded bio crude in the range of 46.86%and 42.68%respectively,when used in combination,DE cateHTL with AQ resulted in maximum bio crude yield of 54.35%.Furthermore,qualitatively,the bio crude from DE cateHTL with AQ presented with a high carbon and energy recovery percentage of 62.20%and 72.95%respectively and a high hydrocarbon content of 58.98%.
