US: Continental Cement has ordered a Fuelflex Pyrolyzer alternative fuels combustion system from Denmark-based FLSmidth for installation at its Davenport plant in Buffalo, Iowa. The supplier says that its product offers a lower capital expenditure compared to competing systems, can control NOx emissions without the need for ammonia water and can be installed without a long shutdown period. This is the first commercial installation of the Fuelflex Pyrolyzer system following a pre-commercial installation at the Mannok cement plant in Northern Ireland, UK, in 2022.

David Loomes, the president of Continental Cement, said “We’re very excited about what the Fuelflex Pyrolyzer will do for our process.” He added, “We’re planning to achieve 55% fossil fuel replacement across the plant, utilising non-hazardous waste that would otherwise go to landfill or incinerators. The economic and environmental benefits of this technology are very significant and a key element of executing our carbon reduction commitment.” Continental Cement, a subsidiary of Summit Materials, has been incorporating waste materials as fuels for more than 30 years.

Jens Jonas Skov Larsen, Head of Capital Sales at FLSmidth, said “Mannok has called the Fuelflex Pyrolyzer a game-changer for the cement industry.” He continued, “This system effectively rearranges the order of the combustion process to make use of hot preheater meal, which is the heat source for the waste fuel pyrolysis. It’s a more efficient way of burning alternative fuels and it comes with a host of benefits, including reduced emissions and a more stable process.”

The installation at Davenport cement plant is expected to start operation in 2024. The full commercial launch for the system is scheduled by 2025. No value for the order has been disclosed.

Denmark: Norway-based Geminor has commissioned a new refuse-derived fuel (RDF) production plant in Aalborg, Jutland. The plant is equipped with a windshifter separator, allowing it to extract up to 70% of plastic in residual waste, in addition to metals and wood. This produces a heavy bio-RDF with low fossil content, of the type previously developed by the company at its HUB research facility in Landskrona, Sweden. Though more expensive to produce than other types of RDF, the company believes the fraction offers higher profitability due to its taxation benefits.

Norway: Geminor processed 67% of waste that it handled in 2021 into refuse-derived fuel (RDF) and solid recovered fuel (SRF). The company said that the figure represents a 3% decline from 2020 levels. It handled a total of 1.73Mt of waste in nine European countries in 2021.

CEO Kjetil Vikingstad said “The Covid year 2021 has been another challenging year for the European waste industry in terms of volumes, logistics, transport and varying market mechanisms. The RDF market, in particular, has differed with lower volumes in circulation due to reduced exports from countries such as the UK and Finland. At the same time, other countries - such as Poland, Denmark, and Italy - have experienced growth, which has helped obtain a balance in the market.”

Vietnam: Denmark-based FLSmidth has started a partnership with Tontoton to help cement plants source non-recyclable plastic waste for co-processing. FLSmidth will work as a technical consultant on the project. The partnership was announced at the ADB Healthy Oceans Tech and Finance Forum: Innovative Solutions for Asia and the Pacific. Local cement producers interested in getting involved are welcomed to reach out to Tontoton for information on how to get started.

“With our process knowledge, technical expertise within co-processing, and waste-fuel firing equipment, we proud to help facilitate a win-win situation for all parties involved,” said Carsten Riisberg Lund, Cement Industry President, FLSmidth.

Tontoton is a Vietnam-based plastic neutralisation program that aims to reduce ocean plastic. It builds personalised plans for companies to reduce their plastic footprint, using the same concept as a carbon footprint. It collaborates with local communities to collect a predefined amount of ocean-bound plastic on behalf of companies, equivalent to their overall plastic consumption or a specific product. It works under the international standard of the Ocean Bound Plastic Neutrality Certification, audited by a third party, Control Union.

Denmark: Norway-based Geminor has established a solid recovered fuel (SRF) production line with a capacity over 40,000t/yr at its Hub waste processing plant in Aalborg. The line will shred and mix municipal solid waste from the region. Geminor will supply 120,000t of SRF to Aalborg Portland Cement over a three year period starting from January 2021. The line includes a chain feeding conveyor supplied by Westeria, a Metso 4000-8 pre-shredder, a Steinert magnetic sorter and a Metso 3550 fine shredder. Aalborg Portland Cement is targeting a 75% SRF substitution rate at its Aalborg cement plant over the period.

Portugal: Cimpor Cement plans to upgrade the kiln line of its Souselas cement plant in order to enable 60% refuse-derived fuel (RDF) substitution in its fuel mix. The producer has contracted Denmark-based FLSmidth to install chlorine bypass technology in order to prevent chlorine build-up in the plant’s flue gas. Work is scheduled to begin in mid-2021, and production will stop until its completion and the commissioning of the installation in early 2022.

Cimpor Cement project manager Paulo Evangelista said, “Investing in the chlorine bypass is a key step on our journey towards reducing our environmental footprint. On top of the obvious incentives to increase our fuel substitution, like lower CO₂ emissions and financial savings, we are experiencing better waste handling infrastructure in the local area. All this has made it an easy choice to make. FLSmidth knows our Souselas site and has been key in delivering a solution that will enable this next phase on our sustainability journey.”

France: Norway-based Geminor subsidiary Geminor France has dispatched a truckload of solid recovered fuel (SRF) to a cement plant in Spain. The SRF is made from wood and textile foam from used furniture. The company says that the delivery is the first of continual 100t/week of exports to the producer. It is also exporting waste-derived fuels from France to other countries in Europe including Denmark.

Senior account and development manager Kai Schöpwinkel said, “There is a positive development at the moment in regards to better collecting and sorting of French waste. Now there is a focus on increasing the combustion capacity for energy recovery, and new waste-to-energy plants are being developed. Stricter requirements from the Government and the European Union (EU) also give incentives to develop high-quality fractions such as SRF based on furniture. The goal is to reduce landfill by 50% by the end of 2025, which will also make France into a growing market for export.” He added, “Covid-19 is leading to a waste deficit in the European market, which is now contributing to the opening of new waste streams from France. We believe this is just the beginning of a growing waste export from this country.”

Turkey: Denmark-based FLSmidth has released details about a new clinker production line it is currently supplying to Bursa Çimento. Work at the site is underway at present covering the line from crushing to clinker cooling. The new line is scheduled to start at the end of 2022. FLSmidth says the equipment it is supplying includes a Hotdisc Combustion Device, which will help increase the substitution rate to 86%, the highest in Turkey. The order also includes an OK Raw Mill, a Rotax-2 kiln, Pfister feeders and new air pollution process filters.

"The modernisation of our Bursa site is a strategic investment, providing us with a more competitive cost base,” said Osman Nemli, General Manager at Bursa Çimento. “But just as important is the entire upgrade which focuses on reducing emissions and power consumption. In this way, we are proactively mitigating future possible environmental regulation."

Denmark: Norway-based Geminor says that it has secured a 120,000t solid recovered fuel (SRF) supply contract with Aalborg Portland Cement. Under the terms of the contract, the company will supply the producer with 40,000t/yr of SRF from 2021 until 2023, with an option for another two years. As a result, Geminor subsidiary Geminor Waste Treatment has invested Euro1.50m in establishing a new SRF production line in Aalborg. The company said, “full capacity for deliveries will be in place” in early 2021.

Geminor Denmark country manager Kasper Thomsen said, “We are very pleased to extend our cooperation with Aalborg Portland Cement, which has been running for several years already. This agreement entails a significant increase in volumes and constitutes a natural development of our collaboration.” He added, “Together with Aalborg Portland Cement we will sort, design and "fine-tune" a waste fraction that meets strict requirements regarding chlorine, biomass and other content. A goal in the long run is to create a good replacement for both petcoke and coal, and thus deliver in line with existing climate goals and the recent Danish waste regulations.”

South Korea: SungShin Cement has placed an order with Denmark-based FLSmidth for the supply of two HotPlate combustion devices for installation in lines three and six of its SungShin cement plant. The plant is in the transition from coal fuel to the possibility of 100% alternative fuel (AF) use in the two lines, which it plans to commission in mid and late 2021 respectively.

Team manager of production technology Cho K-R said, “With its degree of flexibility, the HotDisc allows us to substitute coal with a wide range of AFs – refuse-derived fuel (RDF) in our case. As we turn waste into energy, the HotDisc lowers our operating costs without compromising energy efficiency.”

FLSmidth previously delivered two HotDiscs to South Korea, to SsangYong’s Donghae and Yeongwool cement plants.
