India: Meghalaya Cement, Star Cement and Amrit Cement have been accused of illegally mining 1.8Mt of limestone in Meghalaya between 2013 and 2018. The Northeast Now newspaper has reported that the companies mined the limestone in a tribal area of the state without environmental, forest or wildlife clearance or No Objection Certificates (NOCs). Local cement producers also allegedly owe the state government around US$40m in related limestone mining licence fees. All three cement producers reportedly made donations to a local political party.

The state government is also investigating allegations that two of the cement producers have polluted two local rivers, Wah Lukha and Wah Lunar. The former river allegedly turned ‘deep blue’ due to pollution.

Switzerland: The Federal Council has noted a report stating that, without extensions to raw material extraction licences, domestic cement production is set to decline by 36% from 2024. The Agence Télégraphique Suisse has reported that local producers are already restricted by limited legally available limestone and marl reserves. At present the local cement sector provides 86% of Switzerland’s 5Mt/yr domestic cement demand. The report by the Swiss Geological Survey states that acceptance of all proposed mining expansion projects in 2023 would delay the projected decline until the end of 2030.

India: The Indian Department of Mines and Geology has fined Trishul Cements around US$13.6m for the alleged unlawful extraction of 14,000t of limestone from the Konuppalapadu limestone mine in Andhra Pradesh. The Times of India has reported that the state government terminated its lease of the land in relation to Trishul Cements in February 2020. Investigations unearthed continued mining activity at the site in Anantapur District, along with two other companies’ sites in the Muchakota forest area of the district.

India: ACC plans to sell its National Limestone Company subsidiary to Ghadiya Group for around US$2.5m. National Limestone Company holds mining leases for limestone in the state of Rajasthan. Ghadiya Group operates in the construction and mining sector.

Myanmar: Thailand-based Siam Cement Group (SCG) and Pacific Link Cement Industries (PLCI) joint-venture Mawlamyine Cement has suspended production at its integrated cement plant in Kyaikmayaw, Mon State amidst a dispute between its owners. SCG says it has resorted to arbitration to resolve the matter and that PLCA has filed a lawsuit against it. In a statement SCG said that, “MCL continues to work with distributors and customers to alleviate the supply shortage due to the temporary suspension.”

India: A public hearing over Birla Corporation subsidiary Reliance Cement’s planned 3.9Mt/yr Mukutban cement plant in Yavatmal district, Maharashtra has raised objections against the company’s quarry plans. The Times of India newspaper has reported that the plant is due to source its limestone from a 7.6km² quarry in Korpana, Chandrapur district. Critics say that the company has failed to complete a wildlife management plan, and that the site of the mine lies on a 120km wildlife corridor between the Tipeshwar Wildlife Sanctuary and the Kawal Wildlife Sanctuary in neighbouring Telangana. Reliance Cement said that an environmental report had shown the presence of no scheduled species within 10km of the proposed site.

Maharashtra state wildlife board member and honorary wildlife warden Bandu Dhore said, “Although there is no forest area under the proposed mining site, it acts as a regular corridor as there is forest on either side within 1km. We are pursuing the matter with the forest department and would press it with higher officials to ensure that the precious corridor remains undisturbed. Protection of corridors is a must for conservation of wildlife and hence we are going to raise the demand of re-survey of the project site from the wildlife point of view.”

Japan: Sumitomo Osaka Cement has started using Michibiki, a Japanese satellite positioning system, as part of a demonstration project by its limestone mining operations to improve efficiency. At present the company uses so-called ‘internet of things’ technology such as yard inventory management by drone and rough stone quality management by heavy equipment, including loaders and dump trucks, equipped with Global Positioning System (GPS) tablet terminals. The group operates eight limestone mines in Japan and it mines 20Mt/yr.

Uzbekistan: South Korea-based Caris is considering build a cement plant in the Beruni region of Karakalpakstan. This follows the completion of geological studies in conjunction with the local government, according to the Dunyo News Agency. Caris is now working on a feasibility study for the project before arranging finance.

Bangladesh: Bangladesh Chemical Industries Corporation (BCIC) and Saudi Arabian-based Engineering Dimension International Investment (EDII) have formed a joint-venture called Saudi Bangla Integrated Cement in order to build a new integrated cement plant. The proposed unit will have a clinker production capacity of 12,000t/day, according to the Dhaka Tribune newspaper. It will be supplied with limestone from Meghalaya in India via a long conveyor belt. If realised the project is expected to create up to 700 direct and indirect jobs. Government-owned BCIC previously signed a partnership agreement with EDII in late 2018.

India: Odisha has received its first cement-free road near Amanapada, Cuttack District. The Pioneer newspaper has reported that researchers from the Kalinga Institute of Industrial Technology (KIIT) developed the new material, made from 100% industrial waste, in order to cut the CO₂ emissions involved in cement production and in anticipation of an acute limestone shortage in India in 25 – 50 years. KIIT founder Achyuta Samanta thanked the students whose work brought this pilot project to fruition. “The new technology has the potential to bring about a revolution in engineering construction,” he said.
