The present study reports the parametric investigation conducted on the formulation of biofuels, biolubricant/ biogrease from Mahua (Madhuca Indica) oil and Karanja (Pongamia Pinnata) oil. Biogrease complex has been formulated in 90:10, 80:20 and 70:30 oil/soap ratios for thickness from the oils, their methyl esters and the tri-esters. The experimental results show that the biogrease prepared from Karanja TMP triester showed a drop point of 176 ℃ which was higher as compared to biogrease prepared from Mahua TMP triester which showed a drop point of 172 ℃. The water wash out resistance for both the biogreases was found to be 7%, which is comparable with conventional greases. Based on the cone penetration index, both the biogrease samples were found to fall in NLGI Grade 2 of greases, which is the most common grade of conventionally used greases. Such Biogreases can be effectively used in applications where these greases are directly released into the open atmosphere after their use like agriculture or marine machines and vehicles.

The aim of this research was to investigate the biodiesel production from Pongamia pinnata seed oil and dimethyl carbonate with an iron oxide nano-catalyzed transesterification reaction. A significant biodiesel yield (96%) was obtained with optimal operating conditions as the dimethyl carbonate to oil molar ratio (5:1), iron oxide nano-catalyst (50 mg% based on oil weight), agitation speed of 150 rpm and 60°C temperature for 5 h reaction time. The produced methyl esters from the transesterification process were confirmed to be almost identical to commercial standard biodiesel by thin layer chromatography. The produced methyl esters were analyzed by gas chromatography-mass spectrometry using an internal standard. Properties of methyl esters were characterized such as kinematic viscosity at 40°C, specific gravity at 25°C, flash point, cloud point, pour point, copper strip corrosion and acid value. The properties of the produced biodiesel were within the specifications of the American biodiesel standard, ASTM D6751-02. The results showed that all of tested reaction variables in this study had positive effects. In this research studied, a novel method has developed for production of biodiesel under mild conditions using DMC and iron oxide nano-catalyst. Iron oxide nano-catalyst could be potential candidate for use in the largescale biodiesel production.

“…Aggregates are non-renewable energy sources and recent survey estimates that 694 million metric tons construction aggregates are produced till 2020 (Pacheco and de Brito 2021). In crushing and excavation process though huge amount of petroleum energy is consumed, various researches are carried (Sastry and Pothala 2012;Sastry and Murthy 2015) to find an alternate sustainable petroleum product using natural raw source and still it's in progress for large scale productions. Cracks appear easily in concrete due to its brittle nature and mere tensile strength (Awad et al 2022;Ogunbode et al 2021).…”

Utilization of microbiologically induced calcite precipitation along with fiber composite have great influence on improving strength and durable properties of concrete. The concept of mechanical properties of grouted concrete added with bacteria, steel fibers (SF), rice husk ash (RHA) and light weight aggregate (LWA) has been focused on this work. In the fabrication of concrete specimens, concentration of bacteria, combination of steel fibers and LWA was placed in the formwork, and to fill the voids flowable grout was injected. The variables studied in this work are two different sizes of LWA viz., 10 mm and 12.5 mm with constant dosage of 2% hooked end steel fibers by volume of concrete, 10% RHA was used as cement replacement for preparation of grout and bacteria was incorporated in cement grout by direct application. The properties such as compressive strength (CS), compressive strength regain (CSR), crack width healing, impact strength for first crack and final failure, rate of healing was studied for pre-cracked specimens using visual and microscopic observation. In addition, microstructure was studied for grouted concrete without bacteria and with bacteria under immersed curing conditions. From the experimental results, performance of bacteria added grouted concrete properties such as CS, CSR, cracking healing capacity, and impact strength has improved with the addition of fibers.Utilization of microbiologically induced calcite precipitation along with fiber composite have great influence on improving strength and durable properties of concrete.
