AES Gener explores options to sell synthetic gypsum and ash
AES Gener is exploring options to sell by-products from its Guacolda coal-fired power station to cement producers. The power-generation company has asked for permission to do so and has approached Polpaico, owned by Holcim, and BSA, owned by Hurtado Vicuna group, according to the Diario Financiero newspaper. Guacolda produces around 40,000 t/yr of synthetic gypsum and 60,000 t/yr of ash. AES Gener is already selling 30,000 t/yr or half of the ash generated at its Ventanas power plant, to Mel+¦n.
