Philippines: Aboitiz Group food and agriculture subsidiary Pilmico Foods says that it has developed a waste ash-based concrete mix that contains 20% less cement than its previous mix and that “can be used for all of the company’s construction needs.” The Manila Bulletin newspaper has reported that the ash is sourced from burnt rice husks, a fuel source for Pilmico’s food production and itself a by-product of its operations. Central Maintenance Department mechanical supervisor Michael Cayabyab said, “When we started using the biomass boiler almost two years ago, we saw process improvements and reduced costs. But in Pilmico, we know that the challenge does not stop there." The company has yet to commercialise the concrete, however it hopes to inspire others with its “demonstration of the circular economy demolishing the divide between industries.”

Mexico: Cemex says that 70,000t of its concrete has been used in the construction of Park Garage, a 10,000 vehicle-capacity multi-storey car park in Heroica Veracruz, Veracruz State. The company used a 500m³/day Vince Hagan batching plant and 12 mixing trucks to distribute concrete throughout the complex. Mexico regional president Ricardo Naya said, “We supplied specialised high-resistance concrete to counteract the severe salinity conditions that prevail due to the edifice’s proximity to the sea. Park Garage is yet another example of our ability to offer the highest quality products and services designed to meet our customers’ most demanding requirements."

In the last few months, we have seen many occasions of relationships being built and bonds of togetherness being created. The film is our salute to this spirit of togetherness and coming together of people."

India: State-owned energy supplier NTPC Limited has announced the shipment of 3450t of fly ash from its 3.0GW Rihand power station in Uttar Pradesh to Switzerland-based LafargeHolcim subsidiary ACC Cement’s 3.0Mt/yr Tikaria grinding plant, also in Uttar Pradesh. The Orissa Diary newspaper has reported that the shipment – the first from a new purpose-built rail depot – over 458km is part of NTPC Limited’s commitment to 100% total fly ash utilisation, up from 73% in the 2020 financial year, ended 31 March 2020. ACC supply chain head Suresh Rathi said, “This will pave the way for efficient and safe transportation of all fly ash from power plants to cement production units located at a distance in larger quantity.”

NTPC Limited generates some 60.5Mt/yr of fly ash alongside 62.9GW of power.
