Sustainable Project Based Learning (SPBL), an approach which sustains on the root depth learning of concepts and can help to improve the ability of the students, to develop cognitive and socio-emotional skills. These skills, are the need of the hour and are required, to be successful in academics and also in professional life. The present educational system emphasizes more on the theory, and less attention is given for practicals and SPBL.In project-based learning (PBL), the teachers' guide the students, in applying the engineering design concepts, and the students work in a team, to find the solution for the problem. The innovative educational proposal, presented in this paper is a sustainable project-based learning approach, which allows the students to develop their technical competencies, through real problem-solving situations.Students are made into teams to carry out mini-project, based on a real problem that requires intellectual understanding. Suggestions were taken through google forms. The suggestions described that the implementation of a project in the earlier stages of Engineering would be extremely beneficial. We have considered a thermodynamic problem as an example scenario for infusing sustainable project-based learning. The same approach can be followed by other subjects in other academic years.The students of 3 rd -year 2 nd semester were allocated a project and assessed based on report writing and presentation. The results were productive and thus enhanced the essence of learning new concepts through a practical approach and has benefitted a lot of students. In future times, it does hold a great position in imparting technical education and a learning environment to future engineers.

In this article, extraction of Azadirachta indica compounds has been done using solvents namely ethanol, methanol, benzene, ethyl acetate, toluene which are widely used in industries as solvents. All the compounds present in Azadirachta indica leaves are supposed to be soluble in solvents but this work has been done to show that different solvents have different capacity to extract the compounds. The semi quantitative analysis has been done with the help of thin layer chromatography (TLC) which shows the efficiency of every individual solvent to extract compounds from Azadirachta indica. Thin layer chromatography can physically separate the compounds from pure extracts hence this method is preferred for analysis purpose. Even composition and their respective percentage can be concluded using various analysis method. It is helpful to analyse the solubility of different compounds of Azadirachta indica in particular solvent.
