New 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 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.

Nigeria: Dangote Cement says that it raised the thermal substitution rate of alternative fuels (AF) in its group cement production by 25% year-on-year in the first half of 2022. It co-processed 67,200t of locally-sourced waste in its operations during the half.

CEO Michel Puchercos said “Although significant increases in energy and AGO costs are impacting production, we are strengthening our efforts to ramp up the usage of AF. Our on-going Alternative Fuel Project aims to leverage waste management solutions, reduce CO₂ emissions and source material locally.”

Egypt: Cemex has signed a three-year cooperation protocol with VeryNile. Local press has reported that VeryNile is in the process of expanding its waste collection capacity. Through the partnership, the cement producer will provide finance for VeryNile's waste collection equipment purchases and cover its operating costs.

Argentina: Holcim Argentina achieved 8.4% alternative fuel (AF) substitution in its cement production in its cement production in 2021. That year, it reduced its CO₂ emissions per tonne of cementitious material by 4.2% compared to 2017, to 505kg/t from 527kg/t.

Waste management partner Geocycle processed 140,000t of waste in 2021, up by 20% from 2020 levels. This included 4000t of waste tyres, which alone eliminated 2300t of CO₂ emissions. Geocycle inaugurated Argentina’s first municipal solid waste (MSW) classification facility in Córdoba in November 2021.

India: Coimbatore Municipal City Corporation says that it has reached a rate of 54,800t/yr in refuse derived fuel (RDF) deliveries to cement plants in Tamil Nadu's Ariyalur District. The Indian Express newspaper has reported that the corporation collects 1000t/day of waste, from which its sorts 150t/day of non-biodegradable waste into RDF. It has launched landfill mining at a 26.7ha tip in Vellalore, where it expects to extract several tens of thousands of tonnes more of non-biodegradable waste.

Nigeria: Dangote Cement says that it co-processed 89,000t of waste as alternative fuel (AF) in its cement production as a group in 2021. The Nigerian Guardian newspaper has reported that the source materials consisted of biomass, waste tyres, fly ash and oil-based waste.

Speaking on International Mother Earth Day on 22 April 2022, head of AF projects Peter Anagbe said that the company continues to demonstrate its commitment to sustainable waste management through its advancement of local community recycling projects.

Panama: Cemex has secured a supply of 30t/yr of industrial waste for use at its Panamanian cement plant from US-based industrial conglomerate 3M. The waste will consist of high-calorific residual foam and wool.

Cemex South, Central America and the Caribbean regional president Jesús González said “We are very pleased to make this alliance that strengthens our company’s path towards our carbon neutrality goal by 2050. Cemex and the building materials industry can play an important role in the creation of a truly circular economy. As evidenced by this agreement, we welcome this challenge and are moving aggressively to create the better circular world of the future.”

India: ACC and Ambuja Cements have together installed a Geocycle Bubble Barrier plastic waste separator in Bhakra Beas Management Board Lake at Sunder Nagar, Himachal Pradesh. The installation will collect the waste for use as refuse-derived fuel at ACC’s Gagal cement plant in the state.

The Holcim India subsidiaries’ first such installation, on the Mantola Canal in Uttar Pradesh, has collected 500t of plastic waste since its commissioning in April 2021, and is targetting a total of 2400t in 2022.

Holcim India CEO and managing director Neeraj Akhoury said "We are committed to building a sustainable future by adopting clean and green technologies. Our efforts and expertise in co-processing has created a unique solution to sustainable disposal of the marine plastic waste that creates pollution. This initiative will also contribute towards promoting circular economy. Taking this mission ahead, we will continue our efforts to implement this innovative technology across the country."

Norway: Geminor processed 67% of waste that it handled in 2021 into refuse-derived fuel (RDF) and solid recovered fuel (SRF). The company said that the figure represents a 3% decline from 2020 levels. It handled a total of 1.73Mt of waste in nine European countries in 2021.

CEO Kjetil Vikingstad said “The Covid year 2021 has been another challenging year for the European waste industry in terms of volumes, logistics, transport and varying market mechanisms. The RDF market, in particular, has differed with lower volumes in circulation due to reduced exports from countries such as the UK and Finland. At the same time, other countries - such as Poland, Denmark, and Italy - have experienced growth, which has helped obtain a balance in the market.”
