Relationships with occupations

Essential knowledge

Types of pulp is an essential knowledge of the following occupations:

Tissue paper perforating and rewinding operator: Tissue paper perforating and rewinding operators tend a machine that takes in tissue paper, perforates it, and rolls it up to create various types of sanitary paper.
Pulp grader: Pulp graders grade paper pulp based on a number of possible criteria, such as pulping process, raw materials, bleaching methods, yield, and fibre length.
Paper pulp moulding operator: Paper pulp moulding operators tend a machine that moulds paper pulp in various shapes, usually for use in lightweight but sturdy packaging material, such as egg boxes.
Bleacher operator: Bleacher operators tend a machine that bleaches wood pulp to serve in the production of white paper. Different bleaching techniques are used to complement the various pulping methods, and to obtain different grades of whiteness.
Paper machine operator: Paper machine operators tend a machine that takes in pulp slurry, spread it out over a screen, and drains out the water. The drained slurry is then pressed and dried to produce paper.
Paper mill supervisor: Paper mill supervisors coordinate and monitor the operations at a paper mill during production of products such as corrugated board, cardboard boxes or padded envelopes. They ensure that production targets, such as quantity and quality of products, timeliness and cost-effectiveness can be achieved. They have a clear overview of ongoing processes, and take quick decisions to resolve problems.
Froth flotation deinking operator: Froth flotation deinking operators tend a tank that takes in recycled paper and mixes it with water. The solution is brought to a temperature around 50°C Celsius, after which air bubbles are blown into the tank. The air bubbles lift ink particles to the surface of the suspension and form a froth that is then removed.
Wash deinking operator: Wash deinking operators operate a tank where recycled paper is mixed with water and dispersants to wash out printing inks. The solution, called a pulp slurry, is then dewatered to flush out the dissolved inks.
Artisan papermaker: Artisan papermakers create paper slurry, strain it on screens, and dry it manually or using small scale equipment.
Pulp technician: Pulp technicians perform technical tasks in the production of pulp. They work in pulp production teams where they maintain machines, resolve technical malfunctions and ensure the production process runs according to specifications.
Digester operator: Digester operators, or cooks, cook wood chips with soda ash or acid to separate the wood pulp from unwanted constituents. They test the resulting solution.
Paper engineer: Paper engineers ensure an optimal production process in the manufacture of paper and related products. They select primary and secondary raw materials and check their quality. In addition, they optimize machinery and equipment usage as well as the chemical additives for paper making.
Pulp control operator: Pulp control operators operate and monitor multi-function process control machinery and equipment to control the processing of wood, scrap pulp, recycable paper and other cellulose materials in the production of pulp. They set up, operate and maintain the machinery, analyse the production results and adjust the process when necessary.

Optional knowledge

Types of pulp is optional for these occupations. This means knowing this knowledge may be an asset for career advancement if you are in one of these occupations.

Wood technology engineer: Wood technology engineers develop materials and components made of wood, construct production facilities and control and monitor the production. They also examine products and materials and advise customers.
Civil engineer: Civil engineers design, plan, and develop technical and engineering specifications for infrastructure and construction projects. They apply engineering knowledge in a vast array of projects, from the construction of infrastructure for transportation, housing projects, and luxury buildings, to the construction of natural sites. They design plans that seek to optimise materials and integrate specifications and resource allocation within the time constraints.
