Carbon Holdings showcased its USD 11 bn Tahrir Petrochemicals Complex (TPC) at the African Investment Forum in Johannesburg last week, it said in a statement. “The Africa Investment Forum represents an important opportunity for us to exhibit our proposed circa USD 11 bn TPC polyolefins plant as an example of a megaproject that is not only potentially transformational for Egypt alone but for the whole of Africa,” said Carbon Holdings Chairman and CEO Basil El Baz.
