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.”
