My question is whether the costs of disposal of dried sludge have been included in the economic model? What further use does dried sewage sludge have? Is it used as fertiliser or disposed of in a waste incinerator?
yes, the cost of sludge disposal is included in the economic model and it also considers transportation to the mainland. The final use of the dried sludge was not taken into account but the water content it presents at the end of the process makes it suitable for material or energy recovery treatments and therefore not exclusively for landfill disposal
