BAT for the electric arc furnace (EAF) process is to prevent mercury emissions by avoiding, as much as possible, raw materials and auxiliaries which contain mercury (see BAT 6 and 7).
Elektrikaarahju protsesside puhul on PVT elavhõbedaheite vältimine elavhõbedat sisaldava tooraine ja abiainete kasutamisest hoidumisega alati, kui see on võimalik (vt PVT 6 ja 7).
