Active Research Project

1. Utilization of mixed food waste and post-extraction solid waste for Bio-energy and wastewater treatment

This project is divided into two parts (i) Utilization of cooked food waste to produce bioenergy and (ii) Value added utilization of post extraction solid waste, spent carrot seed in biofuel production and in wastewater. Cooked food waste collected from dining halls is subjected to Pyrolysis with and without the presence of catalyst which generates bio-oil rich in long and short chain hydrocarbons. In another part of the project, spent carrot seed, collected from the essential oil industry after the extraction of oil, will be investigated for the value-added utilization as adsorbent, catalyst and feedstock for bio-oil production.

2. Development of a novel biochar based adsorptive membranes from industrial agro-wastes to treat pharmaceutical pollutants.

The primary objective of the research is to develop a biochar-based mixed polymer matrix membrane. The biochar will be obtained from gasification experiments on an industrial agro-waste. The membrane will then be analysed to determine the physio-chemical properties such as the molecular weight cut-off, porosity, permeability, average pore size, pore size distribution, contact angle, zeta potential, and the mechanical strength. Then, its utility to adsorb antibiotics present in wastewater will be evaluated by techniques such as vacuum filtration and UV-Spectroscopy. Lastly, the operational parameters such as temperature, time, and pH, will be optimized to get the maximum adsorption capacity.

3. Optimization of Supercritical fluid extraction process for the selective extraction of Turmeric root and Carrot seed: ANN and DoE Modelling.

Turmeric root oil and Carrot seed oil possess medicinal value such as anti-inflammatory and the antifungal properties due to availability of several compounds in their oil i.e. Turmerone and Curcumin in turmeric oil and Carotol and Daucol in Carrot seed oil. In this project, optimization of operating parameters is carried out for selective extraction of Turmerone, Curcumin, Carotol and Daucol using supercritical fluid extraction method. Since a large number of parameters affect the quality and quantity of extracted compounds, manual optimization is a tedious and time-consuming task. Therefore, DoE and ANN modelling approach will be adopted to maximize the extraction of selective compounds by predicting suitable operating conditions where extraction of other compounds present could be minimized. Variable operating parameters selected for the optimization are Pressure, Temperature, Solvent flow rate, Particle size and Addition of co-solvent. DoE modelling will be carried out using the licensed version of QUANTUM XL Software while MATLAB would be utilized for ANN modelling.

4. Supercritical Fluid drying of high-valued food stuff: An emerging food preservation technique.

India is a major producer of dried & Preserved Vegetable i.e. Onions, Cucumber, Gherkins, Mushrooms, Green Pepper, Asparagus, Garlic Powder, Garlic Flakes etc. Due to wrong practices of preservation and farming, 20-25% of total yield is being wasted. This waste amount could be preserved for future use and India is also a prominent exporter of dried and preserved vegetables to the world.In conventional techniques such as air and solar drying, high temperature (typically 65-85 °C) can cause damage to the microstructure in the form of hardening and shrinkage. It also affects the color, texture, taste, aroma and nutritional value of the product negatively. Low thermal conductivity of foods limits heat transfer to the inside of foods resulting in a lengthened drying process. The Supercritical CO2 drying process works in a similar way to air drying, except that the drying medium consists of CO2 under pressure. Considering the demand of dried/preserved foodstuffs and disadvantages of other conventional techniques, this work is intended to investigate an alternative drying technique, which can effectively provide a good food quality. A comparison study to be performed to compare the Supercritical CO2 drying of high-valued foodstuff with conventional air-drying method based on the qualitative analysis and economic feasibility.The process modelling of Supercritical CO2 drying process will be done using ASPEN Plus software. In addition, a mathematical model for Supercritical CO2 drying process is to be developed considering the mechanism of water removal.
