Golden Bay Cement uses 80,000t of waste in EcoSure reduced-CO2 cement production to date
17 October 2022New Zealand: Fletcher Building subsidiary Golden Bay Cement has co-processed 80,000t of waste in production of its EcoSure reduced-CO2 general-purpose cement at its Golden Bay, Whangarei, cement plant. The plant has achieved a coal substitution rate of 50%. It has processed various waste streams, including 3 million used tyres. EcoSure cement generates CO2 emissions of 699kg/t of product, 20% less than its imported alternatives, according to Golden Bay Cement. Fletcher building CEO Nick Traber said that this figure is 'simply our starting point.' The company's next target is to achieve a 30% CO2 reduction by 2030.
Traber said "We needed to think outside the box, or rather the cement bag to be more precise. The challenge was around what enhancements we could make to our manufacturing processes at our Golden Bay cement works in order to improve the plant's sustainability. We quickly realised that consuming used tyres and wood waste as alternative fuels was a win-win. When we started with the idea in 2015, we were aiming to replace 15% of coal with end-of-life tyres. Fast forward to 2022, and our rate of coal substitution is now at 50%, which has obviously delivered further reductions in carbon emissions, as well as helping to offset increased coal costs."
Philippines: Republic Cement is supporting efforts to remove plastic pollution from the sea by co-processing the waste in its cement production. The Business Mirror newspaper has reported that the cement producer has partnered with plastic waste collector Pure Oceans to take delivery of shipments cleaned up from off the coasts of Batangas and Davao.
Republic Cement chief executive officer Roman Menz said "Republic Cement is proud to partner with organisations such as Pure Oceans. Their deep commitment towards safeguarding the environment, while making significant contributions to the Philippine plastic waste crisis, is an inspiration for us to continue doing what we do in order to make a tangible impact on our communities, towards building a greener and stronger republic."
Through its partnerships with local fishing communities, Pure Oceans diverted 1.93m bags of plastic waste over the three years prior to the start of October 2022.
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.

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.

Cementos Argos to expand Piedras Azules cement plant
21 December 2021Honduras: Cementos Argos plans to expand the production capacity of its 1Mt/yr Piedras Azules cement plant by 35%. The plan is part of a group of planned projects, including solar power and alternative fuels, with a total investment value of US$23m. The company expects to complete all of the work before 2024. It says that the expanded operations will generate 500 new direct job opportunities.
The company will increase its energy supply from the Comayagua solar power plant to 25% of the plant’s requirements from 20% at present. It will also establish a new 1.2MW solar power plant at Río Blanquito. The cement producer will also strengthen its industrial waste co-processing operations with the aim of achieving 12% refuse-derived fuel (RDF) substitution rate by 2030, the equivalent of 5500t/yr. If reached, this will reduce the company’s carbon footprint in the country by 14%.
Chief executive officer (CEO) Luis Eduardo Tovar said "This investment is a vote of confidence of Argos in Honduras and represents our commitment to the country's economic reactivation and our firm determination to contribute to the consolidation of prosperous and sustainable communities based on competitive and visionary initiatives.” He continued “We will continue our efforts to promote the development of Honduran families through the creation of social value at a national level."
