Indian Institute of Technology Madras develops first-of-its-kind ‘Rotary Furnace’

Published

on

Indian Institute of Technology Madras (IIT Madras) developed an indigenous municipal solid waste combustor pilot plant based on a first-of-its-kind ‘Rotary Furnace Technology’ to efficiently process un-segregated municipal solid waste generated in India.

This Combustor Plant was inaugurated on Friday by V. Kamakoti, Director, IIT Madras, was deployed within the Combined Cycle Demonstration Plant premises at the Bharat Heavy Electricals Limited factory at Trichy.

The MSW generated in India is around 133 million tonnes a year of which more than 85 per cent ends up in landfills. The total solid waste generation in Tamil Nadu is 14,600 tonnes/day with around 5,400 tonnes/day generated in Chennai (TNPCB, 2021). The MSW generation is increasing at 1.3 per cent a year with a current per capita generation of around 0.5-1 kg/day.

After the segregation and utilisation of bio-organic wastes for composting, vermin-composting and biogas generation, more than 2,500 tonnes/day of bio-inorganic waste, including plastics and high calorific value matter are dumped in the landfills.

The Indian solid waste management industry is worth $13.62 billion by 2025.

Developed completely indigenously, this facility can process up to one tonne of un-segregated municipal solid waste (MSW) per day and generate steam as the main output along with clean gaseous emissions and ash as a by-product. This initiative was part of the Ucchatar Avishkaar Yojana (UAY) project funded by BHEL and the Union Ministry of Education. It was developed by IIT Madras Researchers at National Centre for Combustion Research and Development (NCCRD).

R Vinu, Associate Professor, Department of Chemical Engineering, IIT Madras, led the project. The entire process from installation to commissioning was completed within six months.

Kamakoti said, “Waste management is becoming an important issue that necessitates solutions that can scale and also help in quick and safe disposal. The first-of-its-kind Solid Waste Combustor developed by IIT Madras not only addresses the scale and safe disposal issues, but also generates heat resulting in a waste-to-wealth creation.”

“It has already been well-tested at IIT Madras for a variety of mixed wastes and up to 40 per cent moisture in the feedstock. The Pilot Plant also contains robust emission treatment units including a bag filter, wet scrubber and dry scrubber to filter and capture the pollutants ensuring emissions are well within the norms,” a statement from IIT, Madras said.

Demand for homes priced Rs 1 crore and above boosts market in India: Report

Published

on

Mumbai, April 24: The demand for homes prices Rs 1 crore and above bolstered the Indian property market in the first quarter this year, preventing overall sales of 65,250 units from hard landing, a report said on Thursday.

Residential sales in Q1 2025 (January-March) experienced only a modest decline and added up to 65,246 units. This limited drop was primarily due to robust demand in the Rs 3-5 crore and Rs 1.5-3.0 crore segments, which helped counterbalance the slowdown in relatively affordable housing, according to a JLL report.

The steady growth in higher ticket size homes indicates increasing affluence among homebuyers, changing lifestyle preferences and buyers prioritising larger and premium properties.

According to the report, housing sales in India’s top seven cities continued to be dominated by Bengaluru, Mumbai, and Pune, which collectively accounted for 66 per cent of Q1 sales.

High concentration of MNCs and startups creating significant employment opportunities and ongoing infrastructure improvements make these cities increasingly attractive places to live and work.

It is interesting to note that over the last few quarters a significant share of quarterly sales volume has been contributed by projects launched during the same quarter.

Q1 2025 was no exception, with around one-fourth of its sales being contributed by quarterly new launches. Launches by reputed developers with assurance of timely delivery and steady price appreciation, are driving the trend, the report informed.

“The residential real estate market is showing signs of a shift in buyer preferences with lowering of demand for less than Rs 1 crore housing and a growing affinity for mid to high-end properties. This as well suggests a potential upward movement in the overall market dynamics,” said Dr Samantak Das, Chief Economist and Head of Research and REIS, India, JLL.

“This upswing in the higher-priced segment demand has shielded the overall housing sales from a sharper decline,” Das added.

Developers are focusing more on mid to high-end projects to align with current demand patterns. High-end housing sector experienced a steady upswing with 107 per cent year-on-year growth in launches of properties priced at Rs 1 crore and above, driven by strong sales in this segment.

Growth in launches despite economic uncertainties signals robust developer confidence in high-end housing demand, said the report, adding that 2025 is poised for robust growth in the residential sector demand.

US tariffs pose major headwinds, need to diversify supply chains: BOK chief

Published

on

Seoul, April 24: South Korea’s top central banker has said global trade tensions sparked by the United States’ sweeping tariff policy are a major headwind for the country’s export-driven economy, and the issue will likely accelerate its efforts to diversify supply chains.

Bank of Korea (BOK) Governor Rhee Chang-yong made the assessment during an interview with CNBC in Washington, where he is attending meetings of the Group of 20 (G20) finance ministers and central bank chiefs, as well as International Monetary Fund–World Bank Group (IMF-WBG) meetings, reports Yonhap news agency.

“We are an export-oriented economy. So the trade tension, definitely, too is large headwinds. We will be affected directly by the U.S. tariffs, and also indirectly to its tariff to other countries. For example, our semiconductor production in Vietnam, car and electronics production in Mexico and our battery production in Canada will be affected,” Rhee said.

“I really hope this trade tension will dissipate, because it’s bad for everybody,” he added.

But South Korea has “some strengths” to manage the issue, as the country has been “luckily” diversifying its supply chains, particularly from China, over the last several years amid growing competition from China and some political issues between the two nations.

“This is a kind of natural movement to diversify our supply chain and also move up to the value chain. So that will continue, but at the same time, the recent trade tension will probably expedite the move,” Rhee said.

Speaking of economic growth, Rhee said it is hard to present a growth outlook due to high uncertainties surrounding the U.S. tariff policy.

“At this moment, I don’t know what kind of trade tension scenarios we have to assume as a baseline or reference scenarios,” Rhee said. “I may have a better idea after tariff talks with the U.S. tomorrow.

South Korea and the U.S. are set to hold tariff talks in Washington on Thursday (U.S. time), as the Donald Trump administration has put on hold the implementation of 25 percent reciprocal tariffs on South Korean imports for 90 days.

South Korea’s real gross domestic product (GDP) contracted 0.2 percent in the January-March period from the previous quarter, according to the BOK’s preliminary data released in the day.

The BOK earlier expected the South Korean economy to expand 1.5 percent this year, but Rhee later said the outlook seemed “too optimistic” and the central bank will come up with its adjusted figure in May.
