Sulfite pulp - bleached (sulfite pulp production)

The activity generating the emissions is sulfite pulp production, bleached. The reference product is sulfite pulp, bleached. The product sulfite pulp is a type of bleached, chemical, wood-containing pulp. It represents Total Chlorine Free (TCF) and Elemental Chlorine Free (ECF) pulp. Chemical pulp is produced by chemical pulping of biomass raw materials, most commonly hardwood and softwood, or also straw from many cereals, bagasse, reed, or esparto grass, and from other annual non-wood plants. The sulfite process is based on calcium, magnesium, and sodium or ammonium bisulfide and produces pulp which is virtually pure cellulose. As the process occurs in acidic conditions one of its drawbacks is that some of the cellulose is hydrolysed, making the sulfite pulp fibres not as strong as other pulps, for example, those obtained with the sulfate process (i.e. kraft pulp). Nonetheless, and although globally the sulfate process is used in up to 90% of chemical pulping processes, sulfite pulps are important for specialty papers (e.g. tissue, glassine) and as a sources of cellulose for various applications within or out of the paper industry. The reference product amount is 1. The cut-off classification is allocatable product. The activity type is ordinary ordinary transforming activity.
