Karnataka submitted draft of mariculture policy, says CMFRI Director
In the background of the Union government designating CMFRI's Mandapam Regional Centre as the Centre of Excellence for the holistic development and promotion of seaweed culture in the country, Mr. George told The Hindu that if global production of seaweed was at 35.5 million metric tonnes, India's share stood at only one lakh tonnes.
300 sites identified
Mr. George said that though the CMFRI had identified 300 sites for seaweed farming in the country, the absence of a mariculture policy for leasing out open water was a hindrance to pushing the cultivation aggressively. Multinational companies (MNCs) that are ready to invest in seaweed culture want a clear-cut policy. MNCs needed a larger area to tap the potential.
He stated that the CMFRI developed guidelines on open-water leasing in the mariculture policy, which were submitted to the Union Department of Fisheries. Now, coastal States will have to form their respective policies.
'Sea area, up to 12 nautical miles from the coast, is under the jurisdiction of the States. They can fix the rates and practical ways of taking up seaweed cultivation. Then MNCs will come and invest,' he said.
'Goa has come out with its policy. Karnataka and Andhra Pradesh have submitted their drafts. The CMFRI is technically guiding and supporting the States in fine-tuning their drafts. We have a team working on this,' the Director added.
Import guidelines
Mr. George said that the Department of Fisheries under the Union government has come out with import guidelines for seaweeds also. 'Now there are proper import guidelines. We can import, quarantine, test, and do farming,' he said.
Notwithstanding, some States have concerns over the impacts of non-native seaweeds on biodiversity, including whether they would replace native species or if they would actually thrive, etc. Such fears will have to be allayed properly, he said.
Mr. George said that when compared to non-native seaweeds, cultivating native ones is not very profitable. 'For example, native seaweed like Sargassum, when dried, fetches ₹11 per k.g. Whereas non-native seaweed like Kappaphycus alvarezii fetches ₹69 per kg,' he said, adding that non-natives, which can fetch a good price, should be imported for cultivation.
He said that seaweed cultivation will have to flourish in the country in many ways. 'Because there is a requirement for bioactive compounds from seaweed, which are being imported by India. It is a great loss in terms of foreign exchange. MNCs have to invest seriously in this seaweed business.'

Lok Sabha passes bill to increase production, processing of critical minerals
Lok Sabha passes bill to increase production, processing of critical minerals Lok Sabha passes bill to increase production, processing of critical minerals 1 2 NEW DELHI: Lok Sabha on Monday passed a bill which seeks to provide a simpler regime for promoting conservation of minerals, zero waste mining and support the objectives of the National Critical Mineral Mission, given the significance of critical and strategic minerals in the development of the country. The Mines and Minerals (Development and Regulation) Amendment Bill, 2025, was passed after brief debate, with Union Minister for Coal and Mines G Kishan Reddy stating that every sector is dependent on critical minerals. The significance of critical and strategic minerals in the development of the country is continuously increasing and recent global geo-political developments has constricted the supply-chains of these minerals. The Centre launched the National Critical Mineral Mission (NCMM) in 2025 to establish a robust framework for self-reliance in the critical mineral sector. Under this mission, the Geological Survey of India (GSI) has been tasked with conducting 1,200 exploration projects from 2024-25 to 2030-31. The Mines and Minerals (Development and Regulation) Amendment Bill was passed amid sloganeering by opposition members over their demand for debate on Special Intensive Revision (SIR) in Bihar. In his reply to the debate on the bill, G Kishan Reddy said that India has less production of critical minerals and is largely dependent on imports. The bill seeks to amend the Mines and Minerals (Development and Regulation) Act, 1957 and also seeks to promote extraction of deep-seated minerals. The minister said efforts have been stepped up since 2015 to boost the availability of critical minerals in the country. "We are moving in the right direction," he said. He emphasised that everyone should understand the value of critical minerals, as every sector, "from electricity and medical equipment to automobiles, defence, solar, and space, is heavily dependent on them". Kishan Reddy said Prime Minister Narendra Modi, during his visits abroad, seeks to expand cooperation in critical minerals. He also attacked opposition parties over disruption in the House, saying they "do not have faith on the Supreme Court, Election Commission". The minister said the Mines and Minerals (Development and Regulation) Amendment Bill, 2025, is an important bill for the mining sector. "Mining sector will be an important pillar and will have a big role in India's journey to Viksit Bhart by 2047," he said. In his brief remarks while moving the bills for passing, Kishan Reddy said critical minerals is the need of the hour and sought unanimous support for the legislation. The bill was introduced in the Lok Sabha on Monday. The Mines and Minerals (Development and Regulation) Act, 1957 has been amended several times over the years. The last amendment made in the Act in 2023 focused on increasing exploration and production of critical and strategic minerals in the country by introducing a new list of 24 critical and strategic minerals; empowering the Central Government to auction mineral concessions in respect of such minerals and introduction of exploration licence for critical and deep-seated minerals. According to the Statement of Objects and Reasons of the Mines and Minerals (Development and Regulation) Amendment Bill, 2025, there is need to provide a dynamic market mechanism for minerals backed by a robust regulatory regime with the increased availability and demand of minerals in the country. "Setting up of mineral exchanges will help miners and end-users of minerals in determining fair and transparent market prices based on supply and demand dynamics, stabilise markets and aid in budgeting and planning. This will promote investment in mining sector and infrastructure related to transport and storage," the statement said. The bill seeks to remove the limit on the sale of minerals from the captive mines so that miners can sell minerals after meeting the requirements of the end-use plant linked with the mine and on payment of an additional amount specified in the Act. It seeks to allow the sale of dumps which have been stacked up to such date as may be specified by the Central Government in captive leases which cannot be captively utilised to reduce environmental hazards and increase safety in mine workings, bring more minerals to the market and provide additional revenue to the States. India is mostly dependent on the import of critical minerals. A National Critical Mineral Mission has been launched to increase domestic production, including from the offshore areas of India, secure supply chains from outside India and promote processing of critical minerals. "There is an urgent need to further amend the Act to support the National Critical Mineral Mission in its objectives," the statement said. The bill seeks to empower the Central Government to promote the development of the market, including trading, of minerals, their concentrates or their processed forms (including metals) through mineral exchanges. It seeks to widen the scope and territorial domain of the National Mineral Exploration Trust to enable the use of the funds accrued to the Trust within India, including the offshore areas, and outside India for the purposes of exploration and development of mines and minerals. The bill seeks to enable one-time extension of the area under a mining lease or composite licence to include therein a contiguous area not exceeding ten per cent. or thirty per cent., respectively, of the existing area under the lease or licence subject to such terms and conditions and additional payment as may be prescribed in rules by the Central Government. "This will promote optimal mining of deep-seated minerals which are locked up in contiguous areas and may not be economically viable to be extracted under a separate lease or licence," the statement said. The bill seeks to rename the Trust as the National Mineral Exploration and Development Trust to reflect its enlarged scope and increase the amount of payment to the Trust by the lessees from present two per cent. of the royalty payable to three per cent. of the royalty payable; It seeks to enable the inclusion of any new mineral in a mining lease, subject to the conditions prescribed by the Central Government and the additional amount payable as specified in the proposed Eighth Schedule to the Act. No additional amount is applicable on inclusion of critical and strategic mineral or minerals specified in the Seventh Schedule to the Act to incentivise production of these minerals which are found in small quantity and are difficult to mine and process.

Cabinet approves ₹18,500 crore semiconductor, infrastructure projects
NEW DELHI: The Union cabinet on Tuesday approved key manufacturing and infrastructure projects worth approximately ₹ 18,500 crore. Among the approvals are four new semiconductor projects in Odisha, Punjab, and Andhra Pradesh; a 700 MW Tato-II hydroelectric project in Arunachal Pradesh; and the expansion of the Lucknow metro over the next five years. With Tuesday's approvals, the total number of semiconductor projects officially sanctioned by the Centre's India Semiconductor Mission has risen to 10, since Micron's memory chip packaging plant was approved in Sanand, Gujarat, in June 2023. Of these, four projects, including India's only modernized chip fab by Tata Electronics, are located in Gujarat, two in Odisha, and one each in Assam, Uttar Pradesh, Punjab, and Andhra Pradesh. Industry stakeholders noted that while the four new projects may not involve large capital outlays, they are strategically important as part of efforts to consolidate investments under the India Semiconductor Mission's first tranche of nearly $10 billion. Ankush Wadhera, managing director and partner, and India semiconductor practice head at Boston Consulting Group (BCG), said that the biggest project under Tuesday's announcements, the SicSem compound chip fab, 'is crucial in various high voltage industrial applications.' 'The list of approved projects until yesterday had one silicon fab, a chip testing and packaging setup, and four chip testing and assembly plants. Even with the modernization of the Centre-owned SCL (Semi-Conductor Laboratory, Mohali), there were some gaps in our nation's semiconductor ecosystem that the new announcements will help address,' he said. Wadhera added that the new announcements could also increase the pace of development and output at the traditional outsourced semiconductor assembly and test (Osat) plants. The four newly approved proposals carry a cumulative investment of around ₹ 4,600 crore and are expected to generate employment for approximately 2,034 skilled professionals, according to an official statement. A silicon carbide semiconductor plant will be set up in Bhubaneswar by SiCSem Pvt Ltd. 'The SicSem project in Odisha is an integrated semiconductor project, which means that it will have both a compound semiconductor fabrication plant, as well as a chip testing and packaging unit. The second Odisha project with HIPS is an advanced packaging plant for glass substrates, which are applicable in crucial industries. The applicant is also making the substrates innovatively, in order to maximize yield—which makes the project very interesting,' said a senior government official close to the developments. Compound semiconductors are made from silicon combined with other elements. They require different fabrication techniques and are primarily used in strategic industrial applications such as space launches, high-intensity sectors like automotive and railways, and resilient systems including power grids and oil rigs. Ajai Chowdhry, industry veteran and cofounder, HCL, added that the announced 'mark a very good move by the Centre to diversify the range of semiconductor projects at hand.' 'A compound chip fab was absolutely the ask of the hour, and the Centre has done well to make a well-strategized announcement with it. The announcements also showed the range of excellent state-level semiconductor policies, and many states are offering excellent benefits to the technical firms in the form of land parcels and other advantages. This will contribute further to the overall semiconductor supply chain, which will all go in to support the outright silicon fabs in the industry,' Chowdhry added. Heterogenous Integration Packaging Solutions Pvt Ltd will establish a vertically integrated advanced packaging and embedded glass substrate facility in Bhubaneswar, Odisha, with a planned annual capacity of approximately 69,600 glass panel substrates, 50 million assembled units, and 13,200 3DHI modules, according to the official statement. Advanced System in Package Technologies (ASIP) will establish a semiconductor manufacturing unit in Andhra Pradesh under a technology tie-up with APACT Co. Ltd, South Korea, with an annual capacity of 96 million units. The manufactured products will serve applications in mobile phones, set-top boxes, automobile systems, and other electronic products. 'ASIP's Andhra Pradesh project is also an advanced packaging project for industrial chips, while Continental's project—the smallest of the lot—is a brown-field expansion of India's oldest existing and running chip testing plant. Overall, the projects come to add significant depth to the overall semiconductor ecosystem,' the government official added. Separately, the Cabinet Committee on Economic Affairs (CCEA) approved an investment of ₹ 8,146.21 crore for the construction of the Tato-II Hydro Electric Project (HEP) in Shi Yomi district, Arunachal Pradesh, with an estimated completion timeline of 72 months. The 700 MW project (4 units of 175 MW each) is expected to generate 2,738.06 million units of energy. It will be implemented through a joint venture between the North Eastern Electric Power Corp. Ltd. (NEEPCO) and the Arunachal Pradesh government. The Centre will provide ₹ 458.79 crore in budgetary support for enabling infrastructure such as roads, bridges, and transmission lines, along with ₹ 436.13 crore as central financial assistance towards the state's equity share, according to another official statement. Arunachal Pradesh will benefit from 12% free power and an additional 1% allocation towards the Local Area Development Fund (LADF), it said. This development aligns with the government's goal to reach 500 GW of non-fossil fuel power generation capacity by 2030 as part of its energy transition and net-zero carbon emission targets.

E20 petrol is safe, says govt, amid engine damage, mileage concerns
New Delhi: The government on Tuesday sought to allay concerns over the 20% ethanol-blended petrol (E20) hurting mileage and damaging vehicle engines, saying that the fuel in fact gave better acceleration and improved ride quality. In a statement, the Union ministry of petroleum and natural gas said that vehicle owners do not find any issue related to drivability, metal compatibility and plastic compatibility while using E20 petrol. The ministry also rejected suggestions that E20 causes a 'drastic' reduction in fuel efficiency as "misplaced". "The use of E20 gives better acceleration, better ride quality and most importantly, lowered carbon emissions by approximately 30% as compared to E10 fuel. Ethanol's higher-octane number (108.5 compared to petrol's 84.4) makes Ethanol-blended fuels a valuable alternative for higher-octane requirements that is crucial for modern high-compression engines. Vehicles tuned for E20 deliver better acceleration, which is a very important factor in city driving conditions," the ministry said. Citing Brazil's experience with ethanol-blended fuel, it said that the south American nation has been successfully running on E27 for years with zero issues. The same automakers such as Toyota, Honda, Hyundai among others produce vehicles there too, the ministry said, adding that safety standards for E20 are well established through Bureau of Indian Standards specifications and Automotive Industry Standards. "In most parameters including drivability, startability, metal compatibility, plastic compatibility, there are no issues. Only in case of certain older vehicles, some rubber parts and gaskets may require replacement earlier than in case non-blended fuel was used. This replacement is inexpensive and can be easily managed during routine servicing. It may need to be done once in the lifetime of vehicle and is a simple process to be carried out at any authorized workshop," it said. Users have also complained, citing a NITI Aayog report, that ethanol-blended petrol should be cheaper than non-blended fuel, and that this cost advantage has not been passed on to the customers. The ministry said that in 2020-21, when the report of NITI Aayog was prepared, ethanol was cheaper than petrol. Over time, procurement price of ethanol has increased and now the weighted average price of ethanol is higher than the cost of refined petrol, the ministry said. "Currently, the average procurement cost of ethanol for Ethanol Supply Year 2024-25, as on 31.07.2025, is ₹ 71.32 per litre, inclusive of transportation and GST. For producing E20, OMCs (oil marketing companies) blend 20% of this procured ethanol with Motor Spirit (MS). Price of C-heavy molasses-based ethanol increased from ₹ 46.66 (ESY 2021-22) to ₹ 57.97 (ESY 2024-25)," the ministry said. "Price of Maize-based ethanol increased from ₹ 52.92 to ₹ 71.86 over the same period. Despite the increase in price of ethanol in comparison to petrol, the oil companies have not gone back on the ethanol blending mandate because the programme delivers on energy security, boosts farmers' incomes and environmental sustainability," it added. Describing the concerns as "totally baseless", the ministry said that usage of E20 fuel has no impact on the validity of insurance of vehicles in India. Automobile manufacturers continue to engage with vehicle owners to provide them any support that may be warranted to ensure optimum performance of vehicles, the ministry said. "For a vehicle owner, who believes that his/her vehicle may require further tuning or parts replacement, the entire network of authorized service stations are available to respond to such requests." Regarding moving beyond 20% ethanol blending, the ministry said that it would require careful calibration, for which extensive consultation are underway. This process has involved the same vehicle manufacturers that are already in Brazil as well as other manufacturers, entities involved in supply of feedstocks, R&D agencies, oil companies and ethanol producers. This process is yet to reach conclusion, it said. As per the current plan, the government is committed to using E20 petrol till October 2026. "Decisions for beyond 31.10.2026 will involve submission of the Report of the Inter Ministerial Committee, evaluation of its recommendations, stakeholder consultations and a considered decision of the government in this regard. That decision is yet to be taken," it said.
