Technology description

15 cm mélyre agrotechnikai eljárásokkal 3 w% friss vörösiszapot helyezünk a remediálni kívánt cinkkel, ólommal, vagy kadmiummal szennyezett és savanyú területre.

Description of the novelty of the technology

nem a fémet távolítjuk el, hanem a kockázatot a mobilitás (vízoldhatóság, növényi felvétel) csökkentésével végezzük a remediációt.

SWOT (evaluation in words)
Strengths

Kis ráfordítást igénylő olcsó technológia.
Két szempontból is környezettudatos: mind a leromlott talaj, mind a vörösiszap káros a környezetre, együttesen viszont a környezeti kockázatot csökkentik.

Weaknesses

A környezeti kockázat nem szűnik meg teljesen, mindig marad kockázat, de a talajromlási folyamat, és a szennyezőanyag terjedése megállítható.

Possibilities

Tengervízzel kombinálva akár bauxit bánya remediálásra is alkalmasnak találták

Threats

Nehézfém szennyezés bekerülhet a talajvízbe.
