After all, what are high performance thermomechanical fibers?

The manufacture of cellulose has two paths used:  Mechanical pulping and chemical pulping. Chemical pulping, mainly the Kraft process, is the most used to obtain cellulose. In mechanical pulping, the processes used are TMP (thermomechanical pulp), which is the process used in BO Paper and CTMP (chemithermomechanical pulp), through refiners. In the refining process, wood in the form of chips undergoes the action of shredding in one or more refiners. Chemical and thermal treatment facilitates shredding and contributes to pulp quality, due to greater fiber integrity.

An important point in the mechanical pulp process is yield. In the Kraft process, the yield is on average close to 50%, while in the TMP process it is possible to obtain yields above 90%,  and for CTMP the yield can average between 80 and 90%. In short:  it is possible to obtain more pulp that will be converted into a greater amount of paper using fewer trees. The TMP and CTMP processes also generate less effluent compared to the Kraft process.


Some important points must be monitored during the high-yield pulp process (TMP and CTMP) such as energy consumption, the use of auxiliary products, the temperature and maintenance of the refiners.


The BO Paper company is dedicated to the use of the TMP process and is interested in proving, through the creation of a green seal, the greater sustainability of the high-yield pulp manufacturing process, motivating companies to consume more consciously. There is currently no seal that proves to the consumer company that the paper it is purchasing is obtained from a more sustainable process and with greater use of raw material, in relation to other processes. The BO Paper company intends to innovate in the market with the creation of the seal and encourage the use of products from high-performance pulp.
