IIT-BHUdevelops eco-friendly tech to convert plastic waste into fuel
eco-friendly technology
offers a sustainable solution to the ever-growing plastic waste problem, particularly in urban areas like Varanasi.
Led by Prof Hiralal Pramanik, the research team developed a patented multiphase catalytic pyrolysis reactor that uses low-cost, natural catalysts synthesised from river clay. This innovative system converts commonly discarded plastics such as polyethylene, polypropylene, and polystyrene into diesel and kerosene-range fuel oils.
Prof Pramanik said that this pioneering work is rooted in the pressing environmental challenges faced by the city of Varanasi, where improper disposal of plastic waste led to numerous problems, including frequent waterlogging caused by clogged drainage systems, death of cows that consume plastic mixed with vegetable waste, and the long-term contamination of soil and water bodies due to non-biodegradable nature of plastics. By turning plastic waste into valuable fuel, this technology not only recovers energy but also provides a
sustainable waste management
solution that can significantly improve urban hygiene, animal safety, and environmental health.
The research, which involved extensive field surveys of Varanasi's waste dumping zones, demonstrates the potential of this low-cost and scalable solution to be implemented in other cities as well.
With an Indian patent already granted and recognition in prestigious international journals such as Waste Management and the International Journal of Energy Research, this innovation marks a major step toward cleaner cities and greener energy. The team is now working on scaling the technology for commercial production, envisioning a future where waste-to-energy solutions play a key role in nation-building and environmental conservation.
IIT-BHU Director Prof Amit Patra praised the outstanding research work of Prof Hiralal Pramanik and his team, calling it a commendable contribution toward sustainable development and environmental stewardship.

IIT-Kanpur gives direct entry to 5 Olympiad achievers
Lucknow: Bypassing the traditional JEE Advanced route, IIT-Kanpur has admitted five students to its Bachelor of Science (BS) and Bachelor of Technology (BTech) programmes based solely on their performance in international science Olympiads and training camps. IIT-Madras has also launched distinct admission pathways, including Sports Excellence Admission (SEA) and Science Olympiad Excellence Admissions (SCOPE). Recently, IIT-Gandhinagar also announced admissions through the Olympiad route, with specific criteria and guidelines published on its site. IIT-Bombay has also announced to admit students into its BS Mathematics programme through the Indian National Mathematical Olympiad (INMO) pathway. Talking to TOI, IIT-K director Prof Manindra Agrawal said: "We are happy to note that five students have been admitted through the Olympiad programme at IIT-Kanpur. We initiated this channel to admit bright students who may not be able to do well in JEE Advanced due to their preoccupation with Olympiad training." "We hope that this will motivate our bright students to train seriously for the Olympiad and bring laurels to the country," Prof Agrawal said. Last Nov, IIT-Kanpur pioneered an alternative admission route, allowing students to join its programmes based on exceptional performance in prestigious international Science Olympiads. The eligible competitions include International Mathematical Olympiad (IMO), International Physics Olympiad (IPO), International Chemistry Olympiad (IChO), International Biology Olympiad (IBO) and International Olympiad in Informatics (IOI). This innovative approach recognizes and rewards global talent in specific subjects. Under this programme, IIT-K offers reserved seats in five departments: Biological Sciences & Bioengineering, Computer Science & Engineering, Chemistry, Economic Sciences, and Mathematics & Statistics. Admission through this route will allow a limited number of seats per department specifically for students who have undergone rigorous preparation and training in relevant Olympiad camps. The five selected candidates hail from diverse regions, with two students each from West Bengal and one each from Delhi, Maharashtra, and Karnataka. Notably, two candidates were selected from the International Olympiad in Informatics Training Camp (IOITC), while the remaining three were chosen from the International Mathematical Olympiad Training Camp (IMOTC). Eligibility for this pathway requires candidates to be of the same age as JEE (Advanced) candidates and to have taken their class 12 (or equivalent) exams for the first time in either the year of admission or the year prior, with Physics, Chemistry, and Mathematics as compulsory subjects. Candidates must have attended the relevant Olympiad training camp in the subject for which they are applying. Those who were previously admitted to IITs via JoSAA or had an IIT admission cancelled are not eligible. The selection process involves two stages. Initially, each department will review applicants based on their Olympiad rankings and shortlist candidates accordingly. These candidates will then participate in a written examination, which is mandatory, and an interview, if required. Prof Shalabh, dean of academic affairs, IIT-K, said, "We are cultivating a diverse academic environment rich in innovation and critical thinking. Our goal is to enhance our academic community with individuals who bring unique perspectives and exceptional analytical skills. Through this initiative, we aim to support and promote innovation in disciplines that are essential to India's growth and global competitiveness.

PixxelSpace India-led consortium to establish India's first commercial earth observation satellite constellation
The Indian National Space Promotion and Authorisation Centre (IN-SPACe) on Tuesday announced the selection of the PixxelSpace India-led consortium to design, build, and operate India's first fully indigenous commercial earth observation (EO) satellite constellation under the public-private partnership (PPP) model. The Bengaluru-based PixxelSpace India consortium comprises Piersight Space, Satsure Analytics India, and Dhruva Space. IN-SPACe said the selection of the PixxelSpace India consortium was done following a competitive bidding process which involved two more consortia. It is for the first time in the history of the Indian space sector that a private consortium would invest more than ₹1,200 crore over the next five years to launch a constellation of 12 state-of-the-art EO satellites equipped with panchromatic, multispectral, hyperspectral, and microwave Synthetic Aperture Radar (SAR) sensors. The constellation will deliver Analysis Ready Data (ARD) and Value-Added Services (VAS) for applications in climate change monitoring, disaster management, agriculture, infrastructure, marine surveillance, national security, and urban planning, while also catering to the global demand for high-quality geospatial intelligence. IN-SPACe said that by generating high-resolution, indigenous satellite data, the initiative will significantly reduce India's reliance on foreign sources, ensure data sovereignty, and position the country among the global leaders in space-based data solutions. 'This initiative signals the coming of age of India's private space industry in the space sector. It demonstrates the capability and confidence of Indian companies to lead large-scale, technologically advanced, and commercially viable space missions that serve both national and global markets. The EO -PPP model fosters an ecosystem where public and private capabilities reinforce each other to drive growth, innovation, and self-reliance,' Pawan Goenka, chairman, IN-SPACe, said. Under the PPP framework, the Union government will provide strategic, technical, and policy support, while the PixxelSpace India-led consortium will own and operate the EO system, including satellite manufacturing, launches from Indian soil, ground infrastructure, and commercialisation of data services.
