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.

South Korea: SK Group subsidiary SK Ecoplant has partnered with CMD Group to launch pilot production of building materials made using up to 60% recycled bottom ash from waste incinerators. The partners say that an exothermic reaction in the presence of non-sintered inorganic binders and expansion-reducing reactants increases the compressive strength of the end product to match that of concrete containing ordinary Portland cement (OPC).

AJU News has reported that South Korean waste incinerators produced 2.16Mt of bottom ash from 9.12Mt of waste in 2020.
