Thai cement plant installs ThyssenKrupp Polysius' Prepol SC alternative fuels system
19 January 2023Thailand: ThyssenKrupp Polysius says that it has successfully supplied and installed a Prepol SC alternative fuels (AF) system at a 12Mt/yr cement plant in Thailand. The system will supply the plant's four lines with 4000t/day of AF.
ThyssenKrupp Polysius' Asia Pacific CEO Lukas Schoeneck said "Asia Pacific, with its tremendous municipal solid waste (MSW) problem, is ideal when it comes to replacing coal with AF. The Prepol SC technology significantly reduces the need to treat MSW before using the inherent calorific value. Additionally, it helps to further reduce the ambitious CO2 limit targets in the region."
Cemex opens Tunjuelo Circularity Centre
13 December 2022Colombia: Cemex has announced the launch of the Tunjuelo Circularity Centre at its former Tunjuelo quarry near Bogotá. Having rebuilt parts of the 50m-deep quarry with demolition waste, Cemex will now work on its ecological restoration, while continuing to receive excavation waste for reconstruction of the ground. It will meanwhile divert demolition waste deliveries for recycling in aggregate production. In Bogotá, Cemex has launched an initiative for urban construction partnerships in collaboration with local authorities. It will also collect municipal solid waste (MSW) there for use in its cement production and collect its used plastic cement bags for recycling in building materials production.
Cemex’s Colombia and Peru president Alejandro Ramírez said "This is a pioneering model for Cemex in the construction materials industry globally, which we aim to position as a benchmark for circularity within the sustainable development of large cities in Colombia and the world. A piece of land that supplied materials for Bogotá's development for decades has received construction and demolition waste for its redevelopment and was transformed into a green area to the south of the city, an epicenter of the circular economy and an opportunity for urban development for the capital city of Colombia."
Philippines: Holcim Philippines has signed a deal to receive 6.5t/yr of shredded waste from Bunawan municipality’s Panacan barangay for co-processing as alternative fuel (AF) in its cement production. SeeNews has reported that Holcim’s waste management subsidiary GeoCycle will process the AF. The partners aim to increase the volume of deliveries in future.
Davao cement plant manager Sam Manlosa said, “We are proud to provide our host barangay Panacan a sustainable waste management solution and thankful for their trust. We hope this partnership will further expand to other communities and the entire city of Davao so we can be a stronger partner in its sustainable progress.”
Panacan is the 28th community throughout the Philippines to enter into a waste management partnership with Holcim Philippines, and its 18th new partner in 2022. In August 2022, the company secured deliveries of waste collected in Bulacan province’s Binangonan, Cainta and Taytay municipalities in Rizal province for co-processing at its Bulacan cement plant.
Philippines: The government’s Department of Environment and Natural Resources – Environmental Management Bureau has called on cement producers to maximise their use of waste plastic as a raw material in cement production. Philippines News Agency has reported that bureau director William Cuñado estimated that the measures would bring about a 40 – 60% drop in national plastic waste generation. He said that local government has a part to play in arranging the requisite municipal solid waste (MSW) practices.
Brazil: The Brazilian Portland Cement Association (ABCP) has joined with the Brazilian street cleaning, waste management and biogas associations in launching the Brazilian Waste Energy Recovery Front for the reuse of waste in energy production. The partners estimated that some 14.5GWh/yr of energy is available for generation from Brazil’s 79Mt/yr of solid urban waste alone. The ABCP said that it was enthused by the possibilities the waste holds for cement producers, and urged the Environment Ministry to ‘reduce regulations that hinder its use.’
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.”
Ash washing begins at Taiheiyo Cement waste incinerator
03 December 2019Japan: Taiheiyo Cement has installed an ash washing facility at a waste incineration plant in Kumagaya, Saitama prefecture for desalination and lowering of chloride content. After rinsing, the installation will supplement cement production at Taiheiyo Cement’s 1.8Mt/yr integrated Kumagaya plant with up to 69,400t/yr of ash. The total cost of investment was US$7.17m.
China: Huaxin Cement’s sales rose by 27% year-on-year to US$1.75bn in the first half of 2018 from US$1.38bn in the same period in 2017. Its net profit nearly tripled to US$304m from US$107m. Its cement and clinker sales volumes grew by 1.13% to 32.2Mt.
The cement producer said that it had been challenged by raw materials and fuel price rises and kiln suspensions due to government-mandated peak shifting production during the reporting period. However, measures such as higher alternative fuels co-processing rates and efficiency gains helped to bolster its financial performance. Its kiln waste processing volumes increased by 18.4% to 0.68Mt.
The company added that its Tibet Shannan 3rd Phase 3000t/day clinker production line was ‘proceeding smoothly’ and was scheduled to start operation by the end of August 2018. Its 4000t/day Yunnan Luquan clinker line and 2.85Mt/yr Huangshi clinker replacement line projects have started construction. In Nepal a 2800t/day clinker line is scheduled to start construction by the end of the year. It is also working on municipal solid waste (MSW) projects in Wuhan Changshankou and Lijiang.
