Beneath this design, the Institute is doing the job on a number of jobs to contribute toward sustainable strength

The University of Strength Science and Engineering, Dept of Chemical Engineering, Dept of Bioscience and Bioengineering at the Indian Institute of Know-how Guwahati are operating actively to make a important contribution to setting up a sustainable long term. Less than the Microalgae Biorefinery Design, numerous study initiatives are underway on Renewable and Sustainable Electricity.

The speedy depletion of fossil fuels, anthropogenic emissions and at any time-escalating electricity consumption has triggered an rising curiosity in choice fuels based on renewable resources. Scientists throughout the world have shown that microalgae-centered therapy of wastewater can be coupled with the simultaneous output of numerous forms of fuels as nicely as other benefit-added items under a biorefinery strategy. 

Some of the big study highlights on related topics involve:

Investigation on reworking residual microalgae/biomass into vitality gas and chemicals

Prof. Vaibhav V Goud, Head, University of Strength Science and Engineering, IIT Guwahati, and Professor, Section of Chemical Engineering, IIT Guwahati, and his investigate group have formulated an successful approach that transforms residual microalgae/biomass into energy gasoline and chemical substances. By utilizing unique alteration techniques, these types of as inhibiting methods, researchers have diverted the course of action cycle to get well the products of option (H2, biogas, and chemicals). As for each their results, the combined use of residual microalgae with biomass (rice straw) aided greatly enhance electrical power restoration. It also offers a sustainable solution for producing a biomass/microalgae-based mostly biorefinery for generating power fuels and chemicals.

 

Research on Integration of wastewater therapy and high-value biofuel production

Prof. Kaustubha Mohanty, Adjunct College, School of Energy Science and Engineering and Professor, Office of Chemical Engineering and his investigate staff have designed an state-of-the-art microalgal biorefinery model that integrates wastewater treatment and high-value biofuel generation through hydrothermal liquefaction (HTL) the place domestic sewage sludge and microalgal biomass are utilized as co-feedstock. The Co-HTL utilised microalgal biomass and sewage sludge as cofeedstock, resulting in 40 per cent biocrude produce and homes similar to petroleum crude. Their developed biorefinery method theoretical conversion and mass harmony prompt that one million domestic sewage wastewater will produce   ̴ 2,500 kg biomass feedstock which even further resulted in 980 kg of biocrude followed by   ̴ 5,000 kg CO2 sequestration. The biomass can provide 600 kg of biofuels to guidance a city bus to run 10 return outings (60 km) for 26 days with 20 for every cent mixing (B20) with business diesel. 

The exploration crew has collaborated with eminent Researchers from national and global companies these types of as IIT Kharagpur, CSIR-IICT Hyderabad, and Specialized College Denmark, to acquire an state-of-the-art biorefinery approach. The business associates for technological innovation transfer involve Purabi Diary Assam, Symbiosis Center, Denmark and HPCL. Presently the workforce is functioning on pilot-scale demonstrations of superior microalgal biorefinery procedures to create biocrude.

Exploration on creating bioalcohols from squander invasive weeds

Prof. V. S. Moholkar, Adjunct school of the University of Electricity Science and Engineering and Professor, the Department of Chemical Engineering at IIT Guwahati and his research team have developed lab-scale know-how for developing bioalcohols like bioethanol and biobutanol from squander invasive weeds that are ubiquitous in northeast India. Prof. Moholkar’s group has developed the sonic fermentation procedure for the synthesis of bioalcohols from blended invasive weeds, which is not only quicker than standard fermentation but also offers better yields. In particular, biobutanol can be blended with petrol up to 80 for each cent due to its pretty equivalent homes to petrol.

  

Exploration on effectively manufacturing liquid hydrocarbon oil

Prof. Debasish Das, Affiliated Faculty of College of Vitality Science and Engineering and Professor, Department of Biosciences & Bioengineering and his analysis team in collaboration with Oil and Purely natural Fuel Company (ONGC) have shown a pilot scale technology for the generation of liquid hydrocarbon oil ALGLIQOL, with a probable to be utilised as transportation gas via hydrothermal liquefaction (HTL) of microalgae biomass developed on CO2. The technology has been formulated by integrating: Method engineering technique for high mobile density cultivation of microalgae biomass lower-expense scalable harvesting of biomass and catalytic upgradation of bio-crude oil followed by fractional distillation.           

Renewable electrical power delivers trusted power supplies and fuel diversification, which boost energy protection and decrease the hazard of fuel spills while decreasing the need for imported fuels. Aligning with the themes of G20 Summit 2023 presided more than by India, IIT Guwahati is producing its best endeavours for improved vitality security, reduced hazard of fuel spills for a far better and secure foreseeable future.

Supply url Scientists from the Indian Institute of Technology Guwahati (IIT-G) have developed a model to produce bioalcohols from sustainable microalgae biorefinery.

The model is based on recent advances in biomass-based bioprocessing technologies and aims to provide a green and sustainable platform for bioenergy production and a substitute for petroleum-derived fuels and chemicals.

The research was based on earlier findings that suggested that microalgae are the richest sources of biomass materials that are easily convertible to biofuels.

Using this model, microalgae were first treated with ionic liquid and hydrolyzed to produce excess sugars. These sugars were then used for the production of bioalcohols, such as bioethanol, terpenes and other important compounds, by different microorganisms.

The research team improved the process with the help of an efficient separation and recovery system, resulting in high-yield bioalcohol production. The process was also found to be economically viable.

As per the research team, bioalcohols can be used as fuel additives or substitutes for the existing fuels. This will help reduce the dependence on fossil fuels and provide an environmental edge to the transport sector.

This model had been successfully tested at the laboratory scale and the team is now working on a pilot project that will be implemented at a commercial scale in the near future.

The study was recently published in the journal Trends in Biotechnology and the findings have been hailed by many as a major breakthrough in renewable energy production.

It can be concluded that IIT-G’s recent research is a significant step towards greener, more sustainable, and more economically viable energy sources. It will not only reduce dependence on fossil fuels, but also pave the way for a more eco-friendly future.
