The Greek Polieco company won the contract to clear up the smaller lindane dump within the defunct OHIS chemical plant in Skopje.

The contractor is hired to remove the toxic waste outside of Macedonia, through a UN program. It’s expected that the work will take between two and a half and three years. There are 6,600 tons of lindane, 1,600 of them highly concentrated, and rest is mostly polluted earth.

The plant has been troubled for over 20 years and has gradually stopped production, with tons of unused chemicals sitting in rusting tanks. Last year an accident during the cleaning of one of those tanks caused acrid smoke to spread across a densely populated part of the city.
