The particleboard line damaged by deflagration on 11 April 2012 at the French company Darbo, which is owned by Sonae Industria, resumed operations in mid-May following completion of repair work. The roughly four-week shutdown of raw board production was partially compensated for by deliveries from other Sonae Industrie plants, in particular from the plant of Auxerre of Isoroy and the Horn-Bad Meinberg plant of Glunz. Melamine lamination continued during the shutdown of the particleboard line. Re-commissioning of the particleboard line had been delayed slightly as a result of a second expertise required by approval authorities.
