Tenova uses cutting edge technology to ensure that environmental protection and compliance with legislation are integrated into the design of each smelting plant. Tenova furnace off-gas scrubbers used with closed furnaces and bag filters used with semi-closed and open furnace ensure that gases from smelting processes are cleaned of particulate matter before the cleaned gases are vented to the atmosphere.

Where needed, the furnace is fitted with a secondary fume evacuation system that captures fugitive emissions around the furnace. Tenova recommends that a suitable Tenova gas cleaning solution be used to ensure optimal furnace performance.
