Mexico advances tyre recycling for cement production
05 July 2024Mexico: The Secretariat of the Environment (Sedema) has reported that over 5600 tyres collected from illegal dumps in the districts of Xochimilco and Gustavo Madero have been transported to a treatment plant to be used as an alternative fuel for cement production. This initiative is part of a strategy to manage tyre waste, supported by a collaboration with Geocycle Mexico. The effort aims to address public environmental issues caused by tyre disposal in public spaces and environmentally sensitive areas, potentially leading to wildfires. Sedema also plans to expand tyre collection through the Reciclatrón Program to promote comprehensive waste management and reduce the reliance on fossil fuels and mineral extraction.
US: Holcim’s Hagerstown plant in Maryland has increased its alternative fuels substitution rate to 45%, equivalent to 58,000t/yr of engineered fuel. This US$11m initiative utilises end-of-life materials like non-recyclable paper, plastics and fibres, sourced from commercial and industrial materials like packaging. Geocycle, a subsidiary of Holcim US, will process these materials at its new Cumberland facility, which has a capacity of up to 75,000t/yr.
Senior vice president of Manufacturing North for Holcim US, Michael Nixon, said "Expanding our alternative thermal energy use to 45% provides multiple environmental and economic benefits, from lowering the net carbon intensity of our cement to reducing our consumption of traditional fuels. Importantly, it enables us to play a role in the circular economy, offering a highly safe and ecological solution for unused materials."
Canada: Lafarge Canada and Geocycle Canada have successfully completed a pilot at the Lafarge Brookfield cement plant in Nova Scotia to produce clinker using recycled minerals from discarded material. This pilot can potentially cut CO₂ emissions by 60% of clinker. The new clinker product will be used to produce recycled cement in 2024.
CEO of Lafarge Canada David Redfern said "Our teams have been tirelessly working towards finding solutions to decarbonise our business in Canada. This new recycled-minerals clinker combines operational excellence with circular construction, building new and green from what is considered old and waste. This is a great example of how far we can go - the local team at Brookfield is certainly setting the tone for the industry in Canada."
Since May 2023, Lafarge Canada, Geocycle Canada and the Holcim Group Innovation Centre have been collaborating on a 100% circular production of clinker at the Brookfield plant. The new production method involves substitution of raw materials with lower carbon options from discarded materials, as well as alternative fuels produced from these materials. The trial was performed in February 2024 and cement from this clinker will be produced in 2024 for further testing and development of the technology.
Philippines: Holcim Philippines will invest US$35m in sustainability initiatives at its four plants over the next three years. The investments will also include US$17.5m for its waste management arm, Geocycle, increasing capacity for local government unit waste processing.
Chief sustainability officer Samuel Manlosa Jr. said "There is also a side where, if we want to take in more volume, we need to increase our capacity to shred and prepare the materials. Our cement plants, even as sophisticated and technologically advanced as they are, were constructed 20 years ago when norms were different, so we had to make changes in the process to make sure that the plants were able to accept more."
The company will further invest between US$8.7m and US$17.5m in renewable energy and electrification of its vehicle fleet. President and CEO Horia Adrian said "We are purchasing electricity right now, but we have plans to put in place solar facilities and we are looking at the possibility of using electricity generated from biowaste here. By the end of 2024, some of them should be ready."
He concluded that investments at the Bulacan and La Union plants are set to start this year, with those in Davao and Lugait scheduled for 2025.
Aggregate Industries to use waste tiles as alternative raw material
24 November 2023UK: Thousands of tonnes of waste ceramics from one of the UK’s largest ceramic tile manufacturers will be recycled to make cement as part of a new initiative from Aggregate Industries. The cement producer, owned by Holcim, has agreed a four-year deal with Johnson Tiles to take 20,000t/yr of legacy waste scrap from its Stoke factory in Staffordshire. They will be transported a short distance to Aggregate Industries’ Cauldon cement plant, where they will be crushed and mixed with limestone and the other raw materials prior to entering the kiln.
Andrew Whyatt, Geocycle UK General Manager at Aggregate Industries, said “We are delighted to be working with such a potteries stalwart as Johnson Tiles in order to recycle what would otherwise be a waste product. Materials such as this offer a great alternative to excavating fresh raw materials, preserving our local natural resources, whilst offering a solution whereby 100% of the material will be upcycled into new local cement. Both companies share a drive towards sustainable manufacturing and partnerships like this are vital as Aggregate Industries aims to reclaim or recycle 3Mt/yr of materials by 2025.”
US: Holcim US has inaugurated a waste tyre processing plant at its Alpena cement plant in Michigan. The facility will process 22,000t/yr of tyres into refuse-derived fuel (RDF) for use at the cement plant. Holcim US partner Geocycle will collect, pre-process and deliver the tyres to the new facility.
Holcim US’ North regional senior vice president of manufacturing Michael Nixon said "Holcim has invested more than US$100m in eco-friendly technologies at the Alpena plant in the past 15 years. The tyre-derived fuel facility is another strong demonstration of our commitment to reducing emissions."
