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.
