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.

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.

China: Jiangxi Wannianqing Cement’s net profit in 2019 was US$197m, representing a 20% year-on-year increase from US$164m. Reuters has reported that on 15 November 2019 Jiangxi Wannianqing Cement paid US$82.6m for a lease and limestone exploration rights for land in De’an County, Jiangxi Province, previously held by Fushan Cement.

India: The state government of Odisha has leased an area of limestone-rich land that includes the Asura Vihara Gumphas, a first century BC cult centre for the Jain religion that remains steeped in local mythology to the present day. The Blink newspaper reported that the site, consisting of three caves, is ‘covered by thick vegetation’ and in need of ‘proper conservation and preservation.’ Indian National Trust for Art and Cultural Heritage (INTACH) Odisha state curator Anil Tripathy said, ‘the caves should be retrieved from the company and the allotment of the site cancelled.’ Toshali Cements is reportedly carrying out limestone surveys on an area, including the caves.

INTACH is in the process of conducting a comprehensive survey of the Mahandi Valley, in which the land lies, and has identified over 1000 monuments of ‘tangible heritage.’

Tanzania: Manyara Cement has shared plans for a 0.2Mt/yr integrated cement plant in Hanang district, for which it has already acquired limestone and pumice extraction licences for sites around Mount Hanang. The plant will use a vertical shaft kiln.
