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.

Egypt: The New Urban Communities Authority (NUCA) of the Egyptian Ministry of Housing (MoH) has engaged BESIX and Oracom Construction for the establishment of a refuse-derived fuel (RDF) processing plant in Cairo. Mubasher has reported that Minister of Housing Assem El-Gazzar has stated that when operational the facility will provide 0.7Mt/yr fuel for cement plants.

Jamaica: Caribbean Cement plans to invest in co-processing tyres as part of a US$9m spend on capital projects in 2019. More details on the project will be disclosed later in July 2019 when a memorandum of understanding is signed with the government, according to the Gleaner newspaper. The subsidiary of Mexico’s Cemex has already spent US$0.5m on handling tyres.

UK: Fairport Engineering is working on an alternative fuels storage and feed system for Cemex’s Rugby cement plant. This project underwent feasibility studies in 2018 and 2019. It is now seeking planning permission and final capital sanction. Once obtained the project execution is likely to take place during a future scheduled kiln shutdown period.

Fairport Engineering has worked on various projects at the Rugby plant since 1998. At this time it supported the installation of a new Polysius kiln with the supply of an associated combined raw materials store. Later it worked on the design and management of a new filter installation in 2006 to support tighter emissions regulations associated with alternative fuels such as a tyre chip and refuse-derived fuel (RDF).

UK: Tarmac has ordered a solid recovered fuel (SRF) handling system from Saxlund International to increase the capability to utilise alternative fuels at its Dunbar integrated cement plant. The SRF system will be installed in the second half of 2019. It is designed for the reception of trucks and storage of fuel in two bunkers. The new system includes processing of fuel to remove ferrous and oversize particles before weighing and dosing into a pneumatic conveying system for kiln injection. The Dunbar plant will use SRF supplied by Hamilton - Solid Recovered Fuel.

“We are delighted to be involved in the development of this new SRF facility at the Dunbar Cement works. The overall system for the reception, storage and conveying of SRF fuel will help to ensure a highly resilient and robust solution for our client,” said Mark Neal, sales manager at Saxlund International.

Hungary: Lafarge Cement Hungary plans to spend Euro6.2m on an upgrade at its integrated Kiralyegyháza plant. The investment will be used to increase its alternative fuels substitution rate to 80% from 60% at present, according to MTI. The unit’s CO₂, emissions will also be reduced by 10%. The upgrade will start in late 2019 with expansion of the plant’s alternative fuels storage capacity planned for the first half of 2020.
