- Wood and other plant materials used to make pulp contain three main components (apart from water): cellulose fibers (desired for papermaking), lignin (a three-dimensional polymer that binds the cellulose fibres together) and hemicelluloses (shorter branched carbohydrate polymers).

- Our pulp and paper process. Paper for recycling is mixed with processed water and then stirred in a giant stainless steel vat, called a pulper, to make a fibre suspension.
- Diluting paper fibres. Our paper machines remove water from the fibre solution. At the start of the papermaking process, the solution comprises of roughly 1% fibre and 99% water.
- Wire section. At the wet end of the paper machine sits the headbox, which distributes a uniform jet of watery stock. The liquid falls onto the wire or forming fabric.
- Press section. The next stage of water removal consists of passing the paper web through a series of nip rollers that squeeze the water out of the pulp mat.
Nov 2, 2021 · Pulp & Paper. Today, the pulp and paper industry is conducting a historic pivot toward packaging materials, as the digital evolution of work and home life continues to drive reduced usage of traditional graphic paper. (we take a look key industry trends in our blog post here).
Oct 1, 2022 · This critical and systematic review seeks to identify alternatives for mitigating the climate impacts of pulp and paper processes and products, thus making the pulp and paper industry more environmentally sustainable.
