Test paper production samples

Acquire test samples at various stages of the paper deinking and paper recycling process. Process the samples, e.g. by adding a measured amount of dye solution, and test them to determine values such as the pH level, the tear resistance or the degree of disintegration.

skill/competence

sector-specific

Test paper production samples is an essential skill of the following occupations:

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.
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.
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.

Test paper production samples is optional for these occupations. This means knowing this skill may be an asset for career advancement if you are in one of these occupations.

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.
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.
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.
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.
