The EPC contract for India?s longest Overland Belt Conveyor (OLBC) system to Heidelberg Cement is another significant milestone in Macmet?s list of achievements.

In 2010 Macmet, against stiff competition from L&T, FL Schmidt, Sinoma International Engineering Co bagged the turnkey contract from Heidelberg Cement for design, engineering, manufacture, supply of equipment, Civil & Structural Construction and Erection of Plant/Machinery for a 21 km long Overland Belt Conveyor system for transporting Limestone from Patharia Quarry to Narsingarh Clinkerization Unit, for the Diamond Cements Plant at Damoh.

The OLBC commissioned for Heidelberg Cement consists of six flights of conveyors, totaling to 20,790 meters. Four flights connect the mine to the Bunker. From the bunker, one flight goes to the Plant and another flight goes to the stockyard. The six flights measure 640 meters, 9800 meters, 8150 meters, 1600 meters, 475 meters and 125 meters (total 20,790 meters). The 1000 mm wide belt conveyor has been designed to transport limestone at an average speed of 4.0 meters/second from the quarry to the plant. The capacity of this conveyor system is 1000 TPH. On its way to the Plant, the conveyor crosses several villages and roads as well as the Sonar River (spanning a width of 120 meters at the cross over).

The conveyor accessories supplied include apron feeders, bag filter with fan, compressors, motorized diverter, Pin/Rod Gate, Magnetic Separator, Metal Detector and Belt Weigher. The electrics include 33KV Substations, Transformers, 690V Voltage Variable Frequency Panels with 690V/350kW Motors controlled by a PLC Automation System.

Macmet undertook the civil work, constructing 890 nos. RCC columns, the maximum height of which was 23 meters at the Sonar River. 4 sub-stations (18,280 cubic meter) as well as a Hopper of 2020 cubic meters were built. The Civil RCC work (including sub-station buildings, bunker, trestle columns and foundations etc.) was completed in one year from November, 2010 to October 2011.

Macmet also completed Structural Fabrication and Erection work of 903 Girders (the maximum span being 47 meters), 61 nos. Trestles (maximum height being 37 meters). The 6025 Ton Fabrication and erection of structural steel work (including transfer houses, gallery, girders, trestles, etc.) was completed in one year from June 2011 to May 2012. About 3300 Tons of mechanical equipment and electrical equipment was also erected.

The 21 km conveyor system passes through several densely populated villages. There was scarcity of water (a significant hurdle for civil construction) and only a single ?kutcha? road running along the route of the conveyor system, which made movement of men and material very difficult. Macmet had to tread the tightrope of handling disgruntled local populace and completing the work within schedule. Land disputes were settled by our interaction with the local villagers and the help of Heidelberg Cement and local Administration Officials.

We gained the confidence of the local people through regular interactions and by conducting social work such as education, provision of drinking water, renovation of places of worship, etc.. Macmet also educated local labour to work in line with safety protocols. We are proud to say that the work was completed without any major mishap and Macmet was awarded the Certificate for conducting work safely. Erection was completed in December 2012 and operation of the 21 km OBLC for Heidelberg Cement commenced in January 2013. Macmet has also been awarded the maintenance contract for the system. The 21 km Overland Belt Conveyor System supplied by Macmet to Heidelberg Cement at Damoh continues to perform satisfactorily since commencement of its operation in 2013. Macmet also has been awarded job for maintenance of the conveyor.

Shree Cement has inaugurated a 60 m³/hour ready-mix concrete plant in Patna, Bihar, under its Bangur Concrete brand. The facility takes the company’s ready-mix concrete (RMC) network to 36 plants across India and strengthens its presence in eastern markets.

The plant was inaugurated by Neeraj Akhoury, managing director of Shree Cement, in the presence of senior company officials and other guests. It has been established to serve demand for ready-mix concrete in Patna and neighbouring areas, where infrastructure development, urban expansion and real estate activity are supporting construction growth.

The facility is designed to supply construction projects across Patna and surrounding markets. Its installed capacity of 60 m³/hour will enable Bangur Concrete to serve customers across the region while improving distribution and supply capabilities in eastern India.

The expansion is intended to improve customer service, strengthen the company’s market presence and support development activity in Bihar. The plant incorporates modern batching technology, material handling systems and quality control processes aimed at maintaining consistency in production and improving operational efficiency.

With the addition of the Patna facility, Bangur Concrete now operates 36 RMC plants across India. The business is expanding its footprint in key construction markets to improve customer access to ready-mix concrete, which is increasingly used in infrastructure, commercial and residential projects because it supports controlled production, consistent quality and more efficient material management at construction sites.

The facility will also follow environmentally responsible operating practices, in line with Shree Cement’s focus on sustainable construction solutions. The latest addition adds capacity to the company’s RMC operations and supports its efforts to serve regional construction markets as development activity continues across Bihar.

Ambuja Plans 2.9 MTPA Godda Cement Unit

Proposed unit forms part of Ambuja Cements’ Rs. 145 bn expansion

Ambuja Cements has proposed a 2.9 mn tonnes per annum (MTPA) cement grinding unit in Godda district, Jharkhand, as part of a Rs. 145 bn expansion programme. The plan is intended to lift the company’s overall cement capacity to 155 MTPA by financial year 2029-30 (FY30), from its current 113.5 MTPA.

The proposal forms part of the Adani Group company’s wider manufacturing expansion across eastern and northeastern India, according to a company statement issued on Monday. The Godda unit would add grinding capacity to Ambuja Cements’ network and is intended to help serve demand in Jharkhand and neighbouring states.

Locating production closer to these markets is expected to reduce transportation costs and delivery times, while the project could support employment in plant operations, maintenance, logistics and administration. The company also linked the facility to indirect activity in transportation, contract services, construction, warehousing and local supply chains.

The expansion plan includes a 2.9 MTPA grinding unit each in Assam and Bihar, as well as additional clinker capacity in Assam. Together, the projects are designed to distribute manufacturing capacity more widely and improve the connection between clinker production and grinding operations, Ambuja Cements’ cement-business chief executive Vinod Bahety said.

Clinker is the intermediate material produced before it is ground and blended to make cement, making the Godda proposal part of a broader materials and logistics network rather than an isolated facility. Ambuja Cements has not provided a commissioning timeline, a Godda-specific investment breakdown, land details or a detailed employment estimate in the supplied announcement.

The project’s impact will depend on implementation of the plant, associated transport links and local supply chains. The announcement sets out the capacity objective but does not specify the project’s construction schedule or operational start date.

Capacity with Conscience

Ambuja Cements has locked in its next phase of growth. The Adani Group company has earmarked 14,500 crore, roughly 145 billion, for greenfield and brownfield projects that will add 30 MTPA and lift its total capacity to 155 MTPA by FY2030.
It is hardly alone. The industry added about 55 million tonnes in FY2025-26, taking installed grinding capacity to an estimated 720 to 730 MT by March 2026. UltraTech Cement, Adani Cement, Shree Cement, Dalmia Bharat and JK Cement are expected to drive another 115 to 125 MT by FY2027-28. Production itself reached close to 490 million tonnes in FY26. The appetite to build is not in doubt.
Costs are another matter. The conflict in West Asia continues to push up fuel and freight bills, and the pressure on profitability is real. More capacity arriving in a market that is absorbing higher input costs leaves little room for inefficiency.
Then there is carbon. Indian cement emits around 0.62 tonnes of CO2 per tonne of cement, and the decarbonisation roadmap points to 0.56 by 2030 and 0.51 by 2047. Output, meanwhile, is projected to climb towards 1,546 million tonnes by 2070, the year India has set for net zero. Intensity can fall steadily while total emissions still rise. That is the arithmetic the industry must solve.
So, how does the sector sustain its expansion momentum while honouring its net-zero commitments? That question anchors the discussions at the Indian Cement Review Conference & Awards and Cement Expo 2026. More than 60 industry leaders will weigh how rising demand, capacity growth and productivity gains can sit alongside decarbonisation across the value chain. They will also examine which technologies, investments and strategies will make that possible.
The Expo runs from 15 to 17 December at India Expo Mart, Greater Noida. Come and be part of the answer.
