Since 2009 Endesa and Botrosa are CARB certified (California Air Resources Board). The audit entity that certified Endesa Botrosa is PSI (Pittsburgh Testing Laboratory Division). PSI performs quarterly audits to the mills, in order to guarantee that the plywood panels that Endesa and Botrosa manufacture accomplish the Phase 2 formaldehyde emission level, which is lower to 0.05ppm.
Endesa and Botrosa implemented a formaldehyde laboratory that allows to constantly monitor the emission level of plywood panels, before their shipment to foreign markets.
