Technology SunPine
Sunpine’s technology is based on converting the residual product tall oil from pulp mills to the products tall diesel, resin, turpentine and biooil Sustainable forestry is Sweden’s oil reserve Despite the fact that we felled four times the amount of forest we had 100 years ago, today we have twice as much standing volume of forest It is the result of planting two to three trees for Over recent times pulp mills have become much more than simply “tonnes per year” in terms of revenue First came the added extra of energy and district heating, then extracts of tall oil and turpentine, now all sorts of areas for extra revenue are being identified at pulp mills As a clear example – and with the help of ANDRITZ – Swedish market pulp giant, Södra, recently started Biomethanol– forming a circular bioeconomy at pulp millsProduction units Metsä Fibre has four pulp mills and six sawmills Our Finnish pulp mills are located in Joutseno, Kemi, Rauma and Äänekoski We have five sawmills in Finland, located in Kyrö, Lappeenranta, Merikarvia, Renko and Vilppula, and in addition to that, we have the Metsä Svir sawmill in RussiaProduction units Pulp mills and sawmills Metsä Fibre
