Co-processing potential for the Vietnamese cement industry23 September 2024, Published under Cement NewsVietnam’s cement industry accounts for 17 per cent of the country’s fossil fuel-derived CO 2 emissions. The drive towards net zero by 2050, supported by the Just Energy Transition Partnership (JETP) and an improved waste management paradigm, is expected to strengthen co-processing in cement kilns. By Dr Kåre Helge Karstensen and Palash Kumar Saha , Foundation for Scientific and Industrial Research (SINTEF), Norway Figure 1: non-recyclable plastic waste originating from plastic ... |
New ISO co-processing standard03 September 2024, Published under Cement NewsThe International Organization for Standardization (ISO) has published a new standard, ISO 4349:2024 for the “Determination of the recycling index for co-processing. The standard introduces a globally-accepted methodology to calculate the share of solid recovered fuels recycled in cement kilns. This share, the recycling index (R-index) is calculated on the basis of the ash content and ash composition. The standard was developed in collaboration with the University of Leoben, Austria, and... |
Republic Cement's ecoloop diverts residual waste to co-processing28 August 2024, Published under Cement NewsRepublic Cement 's resource recovery group ecoloop reported that it successfully diverted 21.4bn plastic sachets in 2023, equivalent to 110,000t of residual waste used, as alternative fuel in the company’s co-processing operations for cement manufacturing. For the year 2023, Republic Cement said that it had utilised over 670,000t of residual waste in its overall cement manufacturing process, including other alternative fuels such as biomass and refuse-derived fuel. This is the largest a... |

Votorantim to receive US$150m loan for Salto plant18 July 2023, Published under Cement NewsThe International Finance Corp (IFC) has proposed a US$150m investment 'A Loan' to Votorantim Cimentos SA for a capex project to enhance the cement co-processing capacity of Salto’s plant , in São Paulo State, Brazil, by upgrading kiln W4 and building a new residue-derived fuel (RDF) facility for refining solid non-hazardous and hazardous waste with an installed capacity of 120,000tpa. Currently, the Salto plant substitutes fossil fuels with approximately 34 per cent of alternative f... |
Natural gas and CO2 abatement across the Atlantic30 June 2023, Published under Cement NewsThis week we look at the differing attitudes to alternative fuels (AFs) on each side of the Atlantic. While CEMBUREAU in its 2022 Activity Report has demonstrated the rising level of co-processing in the EU-27 as achieving 52 per cent, in the USA a study by Global Efficiency Intelligence (GEI) has argued that US cement plants may well do better replacing coal and petcoke with natural gas rather than alternative fuels. Europe is considered the leading proponent of co-processing and the use... |
Holcim Alpena opens new TDF unit02 June 2023, Published under Cement NewsHolcim has opened a new whole-tyre co-processing facility at its Alpena plant in Michigan, USA. The US$7.4m state-supported investment is expected to convert 22,000tpa of tyres into energy to help fuel the company’s cement plant. The tyre-derived fuel (TDF) will initially account for ~10 per cent of the cement plant’s thermal requirement. Construction on the TDF facility started in August 2022, partly funded by a US$3m grant from the Michigan Department of Environment, Great Lakes and Ene... |

Currently, the Salto plant substitutes fossil fuels with app... |
Geocycle and Lafarge Canada to divert waste to Brookfield plant11 May 2023, Published under Cement NewsDriven by its Strategy 2025 ‘Accelerating Green Growth’, Geocycle Canada and Lafarge Canada have been paving the way to use low-carbon alternative fuels to divert household, commercial, and construction and demolition wastes away from landfills. The project will significantly increase the plant’s capacities to pre-process plastics and high biogenic waste materials (banned from landfills in Nova Scotia), and then sustainably co-process these wastes in the cement manufacturing process. T... |
Holcim and Geocycle accelerate green growth03 February 2023, Published under Cement NewsGeocycle and Holcim have been paving the way for using low-carbon alternative fuels to reduce carbon emissions and divert industrial by-product waste from landfill. The US and Canada, in particular, have seen major developments from recent new investment by Holcim and Geocycle. In 2022 Geocycle LLC, a wholly-owned subsidiary of Holcim (US) Inc, claims that it prevented approximately 1.7Mt of waste in the USA going to landfill. It has targeted the provision of finding sustainable solutions... |
