    Changing legislation in the field of waste management is shifting waste management strategies towards waste-to-energy, recovery, and recycling. Historically, municipal solid waste incinerators (MSWI) was seen only as a way of waste disposal, but today's reality is that MSWI can also participate in recycling. The aim of the paper was to determine the recovery potential of the fly ash acid extraction on the real scale from data obtained from MSWI plant in the Czech Republic. The results show, that no long-term variability of Zn content in fly ash was observed, but it varies on a short-term/daily basis. The Zn extraction efficiency is ca 48 %. Current Zn potential for recovery is ca 50 tonnes per year, but it can be increased by 10-23 tonnes after acid extraction step optimization.
