Board of Directors

Raul Kirjanen

Raul Kirjanen started Estonia-based Graanul Invest in 2003 in a small office, and today the company is Europe’s largest manufacturer of wood pellets, employing more than 500 people through numerous subsidiary companies in the Baltic States.

Recently, CEO Kirjanen was elected to the steering committee of the Forestry Development Plan as a commissioner of the Estonian Renewable Energy Assn. Kirjanen believes the main problem of Estonian forestry is that a significant part of Estonian private forests are in poor condition and thus maintenance and renewal of forests should form the cornerstone of the Forestry Development Plan.
