Altri is a leading Portuguese eucalyptus pulp producer and one of the most efficient European producers. 

The company is listed on Euronext Lisbon and a member of its main index (PSI20).




Altri main focus is the production of eucalyptus pulp, being one of the lowest cost producers in Europe.

Altri’s three pulp mills – Celbi, Caima and Celtejo – have a technical capacity to produce above 1 million tonnes per year. Breakdown as follow: Celbi - 800,000 tonnes per year; Celtejo - above 260,000 tonnes per year; Caima - above 115,000 tonnes per year.

Celbi and Celtejo produce BEKP. Caima is producing DWP.

Altri - through its subsidiary Altri Florestal - manages a forest area of about 83.5 thousand ha in Portugal all certified by the FSC® (Forest Stewardship Council) and PEFC (Programme for the Endorsement of Forest Certification), the main references in forest certification worldwide. The wood self-sufficiency rate stands around 20%.

Apart from the biomass, the company also has a strong focus on cogeneration. The pulp mills operated by Altri are entirely self sufficient on power that is produced through the burning of wood components not suitable for pulp production - the black liquor. In that sense, Altri sells about 500 GWh of electric power through cogeneration per year.

Altri’s rapid growth has been fuelled by successful acquisitions (Celtejo in 2005 and Celbi in 2006) and further integration and expansion. The main investment decision metric is Return on Capital Employed.

Our strategy is to maximize the value from our main asset – the forest – and to continue growing the pulp business, adding new incremental capacity through debottlenecking projects and through new value accreative options

To optimise forest management, Altri - through its subsidiary Greenvolt - develops a single renewable source of energy: biomass. This company has currently 96.7 MWh in operation (5 power plants), producing a total of 720 GWh per year.
