How a Paper Mill Works
Pulping, bleaching, forming and drying paper take a lot of water and energy, so mills need large investments and careful environmental management.
A mill turns fibre and water into a continuous sheet of paper.
Pulping
Fibre is broken down mechanically or chemically into pulp.
The paper machine
Pulp is spread on a moving screen, pressed and dried into a long roll that can be several metres wide.
Water and energy
Paper making uses a lot of water and heat, so many mills install their own power and recycle water.
Pollution
Wastewater from pulping and bleaching must be treated, and rules for mills have become stricter.
One modern paper machine can run day and night and produce hundreds of tonnes a day.
It depends on technology and enforcement, not just size.
- Fibre is pulped and formed into sheets.
- Water and energy use is high.
- Pollution control is essential.
- Machines need big capital investments.
