Paper mills convert wood products into pulp for papermaking, using chemical and physical processes to break down the material into cellulose. They can also use recycled materials and undergo certification procedures for environmental responsibility. However, they can produce unpleasant odors and use polluting chemicals, causing controversy in some communities.
A paper mill is a facility that converts wood products into pulp for papermaking. Paper companies may own or lease pulp mills to meet their raw material needs. These structures vary in size and use a number of different processes in making pasta. Staff sizes can vary, but typically include people such as paper engineers, chemists, and technicians to run and maintain the equipment. Employment prospects may depend on the paper products market.
Paper mills can use chemical and physical processes to transform raw materials into pulp suitable for paper. These processes break down the material into cellulose and grind the fibers into a uniform size for various types of projects. The facility can also bleach the raw pulp to produce clear, white papers and can add dyes to create colored paper products. Custom executions are available for specific projects; in factories that supply pulp for the paper used to print money, for example, the manufacturing process is very precise for reasons of consistency and safety.
Kraft, sulfite and other chemical processes can be used in a paper mill. In addition to handling raw wood products, they can also take recycling materials, such as waste paper rags and paper products to make recycled paper. Recycled to virgin content percentage may vary by product; very high percentages can create weaker, less durable products that don’t perform as well, so the pulp mill must balance environmental concerns with consumer needs.
Some pulp mills use certified lumber and recycled products and undergo certification procedures so they can carry special seals on their products. These seals can testify to environmental responsibility and stewardship and can be an asset on the finished card. Some customers request certified wood products and actively seek out these labels, while others may find them appealing when they’re buying paper in-store. Maintaining certification may require periodic inspections and submission of material for analysis and testing.
Paper mills have historically been a subject of controversy in some communities. A paper mill can produce strong, unpleasant odors and can use highly polluting chemicals in its processes. Before the development of stringent environmental regulations, some dumped waste directly into waterways and caused significant environmental problems. Members of the communities where such mills are located or proposed may agitate against them due to health and safety concerns.
