Innovative Ethanol Production Method Developed in Himachal Pradesh

Shimla, India Jul 30, 2026 ALN: Shimla: In a breakthrough for sustainable energy, a young researcher from Himachal Pradesh has developed an innovative technology to produce ethanol without relying on traditional feedstocks such as sugarcane, maize, or rice. The development comes at a time when India is aggressively promoting ethanol-blended fuel to reduce dependence on fossil fuels and cut carbon emissions.

Kritika Sharma, a native of Mandi who recently completed her PhD from Himachal Pradesh University, has developed a green chemistry-based process that converts agricultural residues, fruit and vegetable waste, and forest biomass into ethanol. This innovative approach not only utilizes materials that are often considered waste but also aligns with global efforts to find more sustainable energy sources. The technology offers a sustainable alternative to conventional ethanol production methods, which are heavily dependent on water-intensive crops like sugarcane.

Sharma's process is particularly significant in the context of India's ongoing water crisis, where many regions are facing severe water scarcity. Traditional ethanol production methods require substantial amounts of water, exacerbating the challenges of water management in agricultural regions. According to Sharma, the newly developed process requires significantly less water than traditional ethanol production techniques, making it particularly suitable for regions facing water scarcity. The technology has completed laboratory-level testing, and a patent application has already been filed. The innovation is currently undergoing the patent verification process.

Recognising the potential of the research, the incubation centre at NIT Hamirpur has extended financial support through an Ignition Grant of ₹4 lakh to help advance the project towards commercialisation. This support is crucial as it can facilitate further development and testing of the technology, potentially leading to its wider adoption. The financial backing from the incubation centre underscores the importance of fostering innovation within academic institutions and supporting researchers who are addressing pressing environmental challenges.

At present, ethanol produced through the laboratory process costs around ₹60 per litre. The research team aims to reduce the production cost to nearly ₹40 per litre by scaling up the technology for commercial production. This reduction in cost is vital for making the technology competitive with traditional ethanol sources, which can influence market dynamics significantly. To further improve sustainability and reduce operational costs, the project also proposes the installation of a water treatment and recycling system, enabling efficient reuse of water during the production process. This aspect of the project not only enhances sustainability but also contributes to the overall efficiency of the ethanol production process.

Sharma said the technology has the potential to provide clean fuel not only for the transport sector but also as a renewable energy source for industrial applications. This versatility is crucial as it opens up new avenues for ethanol use, potentially transforming it into a more widely accepted energy source across various sectors. By utilising waste materials that are often discarded or burned, the innovation could also help address the challenge of agricultural and forest waste management while reducing environmental pollution. The dual benefit of waste management and renewable energy production highlights the multifaceted advantages of Sharma's technology.

Ethanol’s Growing Importance in India

Ethanol has emerged as a key component of India’s clean energy strategy. The Government of India has been steadily increasing the blending of ethanol with petrol under the Ethanol Blended Petrol (EBP) Programme to reduce crude oil imports, improve energy security, and lower greenhouse gas emissions. The country has already achieved significant progress in ethanol blending and is working towards expanding the use of biofuels in the transportation sector. This initiative is part of a broader effort to transition towards a more sustainable energy future, aligning with global trends in renewable energy adoption.

Traditionally, ethanol in India is produced from sugarcane molasses, sugarcane juice, damaged food grains, maize, and surplus rice. However, concerns over water consumption, competition with food crops, and fluctuating agricultural production have prompted researchers to explore alternative feedstocks. Innovations such as Kritika Sharma’s waste-to-ethanol technology could help diversify raw material sources and promote the production of second-generation (2G) biofuels from agricultural and forest residues. The shift towards 2G biofuels is particularly important as it reduces competition with food production and utilizes resources that would otherwise contribute to waste.

Apart from being blended with petrol, ethanol is widely used in the pharmaceutical, chemical, cosmetics, food processing, and beverage industries. It also serves as an industrial solvent, a disinfectant, and a raw material for manufacturing various chemicals. The diverse applications of ethanol highlight its significance in various sectors of the economy, enhancing its value as a renewable energy source. As India moves towards a greener economy, technologies that produce ethanol from waste materials are expected to play a crucial role in supporting renewable energy goals while promoting sustainable waste management and rural economic development.

The implications of Sharma's research extend beyond just energy production. By addressing issues related to waste management, the technology can contribute to cleaner environments, particularly in rural areas where agricultural waste is prevalent. Additionally, the potential for creating jobs in the biofuel sector could stimulate local economies, providing new opportunities for residents in regions that are often economically disadvantaged. The intersection of technology, sustainability, and economic development presents a compelling case for the adoption of such innovations.

In conclusion, Kritika Sharma's innovative approach to ethanol production represents a significant step forward in the quest for sustainable energy solutions in India. As the country continues to navigate the challenges of energy security, environmental sustainability, and economic growth, advancements like Sharma's could pave the way for a more resilient and sustainable future. With continued support and investment in research and development, such technologies have the potential to transform the way India approaches energy production and waste management, ultimately contributing to a more sustainable and economically viable future.
