Chennai Port Trust (ChPT) plans to handle metallurgical coke and petroleum coke to make up for the loss of dusty cargo like coal and iron ore. The new cargo will be handled on a trial basis for six months, according to port sources. Unlike coal and iron ore, met coke being lumpy does not generate so much dust. However, the port will handle the cargo with stringent environment measures. The Tamil Nadu Pollution Board has been informed about this, and technical and legal opinion have been sought on handling of the cargo.
