Part of the appeal is the low price: the cost of sludge disposal is further reduced to just €210 per tonne of dry solid, half the standard cost of landfilling.
Osa huvist on tingitud odavast hinnast: reosetete kõrvaldamine maksab vaid 210 eurot tonni kuivaine kohta, mis on pool prügilas ladustamise tavamaksumusest.
