India: Dalmia Cement (Bharat) has successfully launched its new fleet of 35 liquefied natural gas (LNG)-fuelled trucks from its Murli cement plant in Maharashtra. The trucks are of two types, covering ranges of 50 - 600km, and will transport bagged cement and bulk raw materials. They have 28% lower CO₂ emissions than conventional diesel-powered trucks, and are thus able to eliminate 840t/yr of CO₂ emissions, while also reducing emissions of nitrous oxides (NO_x) by 59% and particulates by 91%, and eliminating emissions of sulphur oxides (SO_x).

Dalmia Cement (Bharat) says that its next move will be to launch a second fleet of 25 trucks from its Ariyalapur cement plant in Tamil Nadu. By April 2024, it plans to convert 10% of its 3000 truck-strong fleet to LNG fuel.

A spokesperson for the company said “Dalmia Cement has been following the business philosophy of Clean & Green is Profitable and Sustainable. Our overall CO₂ emissions have come down from 670kg/t to 467kg/t – one of the lowest globally – and we are focusing on realising our carbon negative goal by 2040. We are delighted to partner with GreenLine Logistics for further reduction of our Scope 3 greenhouse gas emissions.”

UK: C-Capture won an IChemE Global Award in the Energy category for its solvent-based carbon capture system. C-Capture's model differs fundamentally from currently commercially available systems, offering a lower energy penalty than technologies including amine-based capture. It is robust in handling impurities in flue gases, including O₂, SO_x and NO_x, while offering competitive cost and safety performance.

CEO Tom White said “Being shortlisted was honour enough, but to win the global Energy award is fantastic recognition for the C-Capture team and our unique carbon capture technology. The IChemE Global Awards represent the pinnacle of excellence in chemical process engineering. This achievement is testament to our exceptional team and their commitment to accelerating the global adoption of carbon capture and storage to achieve net zero by preventing greenhouse gases from entering the atmosphere.”

Spain: Cementos Molins has committed to a 20% reduction in its CO₂ emissions between 2020 and 2030. The company has set out its strategy in its 2030 Sustainability Roadmap. The roadmap covers five areas: health and safety, energy and climate change, the circular economy, nature and the environment, and corporate social responsibility. Thus, Cementos Molins aims to achieve an accident-free workplace, to source 55% of its electricity consumption renewably, to increase its alternative fuel (AF) substitution rate to 40% and reduce its cement’s clinker factor to 68%, to halve particulate matter emissions and cut nitrous oxides (NO_x) and sulphur oxides (SO_x) emissions by 40% and 10% respectively and to have signed official agreements with all host communities and employ women in over 23% of management positions.

Chief executive officer Julio Rodríguez said “Sustainability is the cornerstone of our strategy here at Cementos Molins, and today we are delighted to announce the specific targets that we have set out in our 2030 Sustainability Roadmap. The targets and their corresponding action plans - the result of the hard work and dedication of the Cementos Molins team, together with our stakeholders – will help drive our company forward in actively tackling climate change.” He added “We are deeply committed to achieving zero emissions and building a better world for everyone.”

China: Henan Province has announced a planned rise in water and energy tariffs for cement producers that fail to meet current emissions standards and clean transportation requirements. Reuters News has reported that companies subject to the measures will pay US$0.07 – US$0.14/m3 more for water and up to US$0.01/kWh more for electricity. Henan enacted ‘ultra-low’ emissions limits of 10Mg/Nm³ of dust, 50Mg/Nm3 of NO_x and 100Mg/Nm³ of SO₂ in 2018. Cement plants in the province produce 105Mt/yr of cement.

Germany: HeidelbergCement’s specific CO₂ net emissions per tonne of cementitious material fell by 1.4% year-on-year to 599kg CO2/t in 2018 from 608kg CO₂/t in 2017. Despite this its absolute gross CO₂ emissions increased by 3% to 76.7Mt from 74.2Mt as clinker, cement, aggregate and concrete sales volumes all grew in 2018. The group has published the data in its Sustainability Report for the 2018 financial year.

“Cutting our CO₂ emissions and handling natural resources considerately are priorities for all our business lines,” says Bernd Scheifele, chairman of the managing board of HeidelbergCement. "We focus primarily on the development of sustainable products and the implementation of concrete measures at plant level in order to achieve our sustainability goals.” The company has set itself the target of a 30% reduction in its specific net CO₂ emissions per tonne of cement by 2030, compared with 1990. HeidelbergCement says it intends to realise its vision of CO₂-neutral concrete by 2050 at the latest.

Other figures of note in the report include an alternative fuels substitution rate of 21.7% in 2018 compared in 20.8% in 2017. NO_x, SO_x and particulate matter emissions all fell. However, total water withdrawal rose by 8% to 65.4Mm³ from 60.4Mm³ although water consumption fell.

India: The Central Pollution Control Board (CPCB) has penalised four cement producers in Tamil Nadu for failing to follow emission standards. Chettinad Cement’s plants at Puliyur and Karikkali, Tamil Nadu Cements’ plant at Alangulam, Dalmia Cements’ plant at Salmiapuram and ACC’s plant at Coimbatore have been accused by the Ministry of Environment, Forests and Climate Change for not complying with emission standards for particulate matter, SO_x and NO_x, according to the New Indian Express newspaper. ACC and Dalmia Cements have been fined around US$420/day since 31 August 2018, Chettinad Cement has been fined around US$5000 for a 12 day delay in compliance and Tamil Nadu Cements has been fined over US$23,000 for a delay of 55 days.
