UK: The Mineral Products Association (MPA) has announced the successful completion of a trial of cement production using a net-zero fuel mix consisting of hydrogen and refuse-derived fuel (RDF) at Hanson’s Ribblesdale, Lancashire, cement plant. The RDF in the mix consists of meat and bone meal (MBM) from the food industry and glycerol from biodiesel production.

Increased alternative fuel (AF) substitution is one of seven key levers in the MPA’s Roadmap Beyond Net Zero emissions reduction strategy. The association says that the fuel will eliminate 180,000t/yr of CO₂ emissions from the Ribblesdale plant’s operations when fully implemented. The project received Euro3.71m in government funding.

Hanson’s environmental sustainability manager Iain Walpole said “We are delighted to be involved with this world-leading project, which is a further example of our commitment to cutting CO₂ emissions.” He added “It will also contribute to our ambition of supplying net zero carbon concrete by 2050.”

UK: Helvellyn Group, a manufacturer of high energy, low impact solid fuels, has announced the official launch of its cement industry direct coal replacement product in Europe.

Helvellyn has chosen the Global Cemfuels Conference (Paphos, Cyprus 19 - 20 February 2020) as the location for the launch and will be sponsoring the event as well as attending in person.

Helvellyn solid fuels are designed to meet the needs of hard to adapt large industrial plants that are seeking to reduce, or even eliminate, their reliance on coal. The fuels are manufactured to replicate the physical and combustion properties of coal, while reducing the greenhouse gas emissions associated with mining, transporting and burning fossil fuels.

This latest renewable coal replacement fuel has been developed to address the specific needs of cement producers, many of whom have already introduced alternative fuels but are now struggling to increase the ratio due to physical, chemical and technical constraints.

Helvellyn’s product allows operators to maintain their existing alternative fuel mix while, in most instances, adding Helvellyn fuel as a direct drop-in replacement for coal from the point of delivery through pre-combustion processing and in combustion.

The Helvellyn fuel for cement production is based on four core principals, high energy, low moisture, low chlorine and ease of handling. While exact fuel specification and presentation can be fine-tuned to meet the specific needs of a given plant, fuel is typically presented as 50mm hard, hydrophobic lumps with the following properties: energy >25kJ/kg (10,750btu/lb, 5.97kcal/kg); ash content <6%; moisture <2%; chlorine <0.07%; carbon >60%; sulphur <0.2%; nitrogen <0.4%.

Frank Harris, CEO of Helvellyn Group, said, “We are delighted to be launching this important product at the Global Cemfuels Conference 2020. The cement industry has shown innovation and leadership in utilising alternative fuels and we believe we can help them to meet the challenges of the next decade as they further reduce the environmental impact of their product. We are excited to meet with the industry and let it see our fuel for the very first time - it is like nothing they will have seen before.”

India: The Confederation of Indian Industry (CII) has lobbied the government in its Pre-Budget Memorandum 2020-21 over customs duties. The body is suggesting a reduction on the customs duty on tyre chips for use as alternative fuel (AF) to 5% from 10%. There is currently no import tax on cement and duties of 5% and below on various clinker constituents.

US: The debate over proposed clean air regulations which may restrict or halt LafargeHolcim’s tyre-burning plans at its 2.0Mt/yr Ravena plant will take place on 23 December 2019. The Times Union newspaper has reported that councillors will debate whether to lower the maximum permitted pollutant emissions from incineration facilities to a level below that entailed by LafargeHolcim’s alternative fuel (AF) plans.

In mid-2018, LafargeHolcim’s licence from the New York State Department of Environmental Conservation for the combustion of 4.8M tyres per year expired. It announced ‘preliminary discussions’ with tyre suppliers in January 2019.

Hungary: Lafarge Cement Hungary has announced plans to upgrade clinker production at its 1.0Mt/yr Kiralyagyháza integrated plant with a Euro1.79m investment in chlorine bypass technology, which uses powdered limestone to remove chlorine and one tenth of the carbon dioxide (CO₂) from gases released in clinker production, which will then be used in clinker cooling. There will be a concomitant increase in the rate of alternative fuel (AF) substitution in the plant’s kilns, with an AF fuel store expansion in early 2020 set to raise AF usage to 80% from 60%.
