South Korea: SK Ecoplant is at the centre of an initiative in partnership with the city administration of Seoul to co-process 52,000t/yr of incineration ash and 110,000t/yr of sewage sludge from the city in local cement production. AJU News has reported that the waste management company expects to supply the raw materials to make 150,000t/yr of cement production under the initiative.
Seoul generates 113,000t/yr of incineration ash and 200,000t/yr of sewage sludge. Currently, recycled incineration ash is used in concrete block and paving slab production, which have a limited strength when using the material.
