Thermo-mechanical pulp (market for)

The activity generating the emissions is market for thermo-mechanical pulp. The reference product is thermo-mechanical pulp. The product thermo-mechanical pulp (TMP) is a type of unbleached, mechanical, wood-containing pulp. Mechanical pulp is weaker than chemical pulp (sulfate and sulfite pulp) but has a higher light-scattering coefficients and opacity. In the TMP production process, wood chips are thermally pre-treated with steam and defibrated in the refiner. Defibration can happen in a single stage under pressure and increased temperature or in two stages under high pressure (~about 3 bar) or at atmospheric pressure. During mechanical defibration, lignin is plasticised and remains in the pulp. TMP cannot be brightened effectively by oxidative and reductive bleaching. The majority of mechanical pulp is produced at integrated pulp mills which directly process it further into (paper-) products and only a minor part of pulp production is sold on the market. TMP pulp is mainly used for Printing & writing papers and newsprint. The reference product amount is 1. The cut-off classification is allocatable product. The activity type is ordinary market activity. Please refer to the ecoinvent documentation here for full details: https://ecoquery.ecoinvent.org/3.11/cutoff/dataset/4581/documentation.
