Japan: Taiheiyo Cement has installed three BWZ bucket elevators and a Louise TKF drag chain conveyor supplied by the Hong Kong-based subsidiary of Aumund at its new power plant at Ofunato. The cement producer uses both biomass and coal at the plant.

Two elevators and the drag chain conveyor are used to transport palm kernel shells (PKS) and palm empty fruit bunches (EFB), which are used as alternative fuels in the power plant. Each has a capacity of up to 150t/hr. The conveying concept is designed so that the different materials are kept apart and enter the silo buffer tanks separately. The third bucket elevator is used for coal handling. It is a gravity discharge type BWZ-S elevator with a capacity of up to 35t/hr.

Netherlands: N+P has awarded an engineering, procurement and construction contract for a 170t/yr SubCoal refuse-derived fuel (RDF) plant in Farmsum, Groningen Province to Germany-based Sutco RecyclingTechnik. The plant, scheduled for commissioning in early 2021, will occupy the site of an existing N+P SubCoal production facility, acquired by the company in 2012.

It said that the new plant will be equipped “to allow further control of key fuel parameters such as chlorine, sulphur and, nitrogen.” It added, “N+P has developed and fine-tuned the SubCoal production method, resulting in plans for a new layout to implement the lessons learned over the past 10 years.” Managing Director David Driessen said, “The decision of the board to go ahead with a full new-build is a clear sign of our ambition to grow and expand across the globe.”

Belarus: Krasnoselskstroymaterialy has announced that its US$7.8m refuse-derived fuel (RDF) plant at its 1.6Mt/yr Krasnoselskstroymaterialy plant will be completed in September 2020. The plant is installed with equipment worth US$4.5m from Czech suppliers. The Ministry of Construction and Architecture has said that waste from the Grodno Recycling and Mechanical Sorting Plant will replace Belarusian peat and Russian coal as the cement fuel in the plant’s kilns, fulfilling Krasnoselskstroymaterialy’s goals of renewability and national self-reliance.

Ministry of Construction and Architecture energy conservation head Sergey Nikitin said, “The transition to RDF will create an opportunity to reduce the cost of cement production in the future, strengthen the financial and economic situation of the Krasnoselskstroymaterialy enterprise and create additional competitive advantages over producers operating on traditional fossil fuels.”

Hungary: Italy-based Entsorga has completed the installation of an automated alternative fuel (AF) line at a Hungarian cement plant. The plant is believed to be Nostra Cement’s 1.0Mt/yr integrated Kiralyegyháza cement plant, which in early 2020 received an AF fuel store expansion aimed at bringing AF substitution rates to 80% from 60%. The upgrade consists of an Entsorga Spider crane and Pelican power system which will be able to maintain a continuous feed to the plant’s calcination system 24 hours a day.

Entsorga CEO Francesco Galanzino said, “Bringing a commission to a successful conclusion in the middle of the maximum intensity period of the coronavirus crisis has been a great satisfaction. The cement plant will make significant savings in CO₂ emissions.”

US: FCT combustion has announced that it has won an engineering, procurement and construction (EPC) contract with Titan Cement for the upgrade of its 5000t/d kiln line to 100% natural gas firing. The upgrade consists of the installation of two new burners: a dual-fuel capability Gyro-Therm Mk3 and a back-up natural gas-firing Gyro-Therm Mk3. The company has said that it will also supply accessories, field instruments, burner management system (BMS) and valve train.

Russia: Italy-based Buzzi UniCem subsidiary SLK Cement has concluded an environmental agreement with the Sverdlovsk Oblast Ministry of Energy and Housing and Communal Services for the co-processing of solid municipal waste at its 1.0Mt/yr Sukholozhskcement plant. AMF Online News has reported that the transition, part of a nationwide government initiative called simply ‘Ecology,’ entails a modernisation of the kiln line, which the company says will be commissioned in 2023 or 2024. SLK Cement general director Andrei Immoreev said that alternative fuels use will not only increase production efficiency, but will also contribute to solving the environmental problems of the region.”

Spain: Holcim España has reported that it has achieved a 10,000t reduction in CO₂ emissions at its 1.5Mt/yr integrated Carboneras plant in Almeria in 2019 by the 30% (60,000t) substitution of alternative fuels for coal throughout the year. Agencia Efa newspaper has reported that the switch was the result of a Euro0.88m upgrade to the kiln line as a part of LafargeHolcim’s Euro20m investment in measures to reduce its Spanish carbon footprint by 90,000t/yr. This also includes the introduction of plant-derived biomass to the Carboneras line by the end of 2020, at an estimated cost of Euro3.1m.

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%.

UK: CRH companies Tarmac and Sapphire Energy Recovery have installed a waste-derived fuel processing unit at the Tunstead cement plant in Derbyshire. The unit will produce 'specialised fuel,' a type of solid recovered fuel (SRF) for the cement plant.

"Using waste-derived fuels is well established in the industry but having our own fuel processing plant on site is a first for us. This project from initial concept to actual results, has been a fantastic collaborative experience between Sapphire's commercial, technical, operational and environmental teams, with strong support from the Tarmac kiln and permitting teams,” said David Wilson, Sapphire’s commercial manager. He added that the companies can adjust the blend and amount they use to suit the production process.

France: LafargeHolcim France and ADEME Occitanie, the French Environment and Energy Management Agency for the region, have inaugurated a waste recovery unit at the Port-la-Nouvelle cement plant. The project has an investment of Euro7.5m with support from ADEME. It has included the installation of a drying workshop, a storage and feeding system to the kiln and a chlorine bypass for the kiln. It is intended to help the cement plant use solid recovered fuel (SRF) achieve a co-processing rate of over 90% by 2022.

The cement plant in Occitanie has been using alternative fuels including used tires, animal meal or industrial wood since 1988. Following the installation of a crushed solid waste valorisation workshop in 2011 it achieved a substitution rate of over 60% in 2018.
