Altri is a leading Portuguese cellulosic fibers producer and one of the most efficient European producers and forest management. Altri is listed on Lisbon Stock Exchange, which holds its main stock market index, the PSI-20.

Altri is a reference European producer in the cellulosic fibers industry, being one of the most efficient producers in Europe of bleached eucalyptus pulp.

Forest management is a central activity of Altri, which manages approximately 90.4 thousand hectares of certified forest in Portugal. The wood self-sufficiency rate is around 20%.


Altri’s three cellulosic fibers mills – Celbi, Caima and Biotek – have a technical capacity to produce above 1 million tonnes per year. Breakdown as follow: Celbi - 800,000 tonnes per year; Biotek - above 260,000 tonnes per year; Caima - above 115,000 tonnes per year. Celbi and Biotek produce BEKP. Caima is producing DWP.


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 (Biotek 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. In terms of stock market evolution, it should be noted that Altri shares started to be listed (March 2005) with a price of Euro 0.15 per share (adjusted value after spin-offs and stock-splits).
