VEHICLE operators along the Wairiki stretch in Bua have raised their concerns over the thick smoke from burnt waste materials beside the road.
This, they say has complicated movement along the stretch.
Labasa bus company owner Parmod Chand said two buses belonging to his company, operating along the stretch had gone off road last week because of heavy smoke emissions. He said the thick smoke emitted from the burnt waste blurred the driver's vision forcing the bus to divert off the main road.
"The heavy smoke along the stretch is dangerous and it is a hazard. It's about getting rid of the debris and smoke away from the roadside and ensuring that vehicles travelling along the road are safe.
Tropik Wood Fiji executive chairman Faiz Khan said a situation arose last week where their biomass fuel self ignited.
He said the practice within the mill was that they did not light up or burn their fuel.
"We do not allow burning of biomass fuel," he said.
"After the incident we have worked with the Department of Environment and relocated the dump site further away from the main highway."
