Bleaching mechanical pulp is not a major cause for environmental concern since most of the organic material is retained in the pulp, and the chemicals used hydrogen peroxide and sodium dithionite produce benign byproducts water and, eventually, sodium sulfaterespectively.

Air Release Valves

However, the bleaching of chemical pulps has the potential to cause significant environmental damage, primarily through the release of organic materials into waterways.

Pulp mills are almost always located near large bodies of water because they require substantial quantities of water for their processes.

An increased public awareness of environmental issues from the s and s, as evidenced by the formation of organizations like Greenpeaceinfluenced the pulping industry and governments to address the release of these materials into the environment.

Dioxins are highly toxic, and health effects on humans include reproductive, developmental, immune and hormonal problems. They are known to be carcinogenic. Disposing of paper in landfill sites, and subsequent breakdown and production of methane a potent greenhouse gas also adds to the carbon footprint of paper products.

This is another reason why paper recycling is beneficial for the environment. Kaolin is the most commonly used clay for coated papers. Mitigation[ edit ] Waste paper awaiting recycling in the Netherlands. Some of the environmental impacts of the pulp and paper industry have been addressed and there is movement towards sustainable practices.

Using wood from plantation forests addresses concerns about loss of old growth forests. Sustainable forest management[ edit ] Cutting down trees to make forest products such as pulp and paper creates temporary or long-term environmental disturbances in forest habitats depending on how carefully the harvest is carried out.

There might be impacts on plant and animal biodiversity, soil fertility and water quality. However, sustainable forest management practices are a way of using and caring for forests so as to maintain their environmental, social and economic values and benefits over time.

In Canada, sustainable forest management is supported by a forest management planning process; a science-based approach to decision-making, assessment and planning as well as by regulations and policies.

The forest certification systems that are currently the most used are: Peracetic acidozone [59] and hydrogen peroxide and oxygen are used in bleaching sequences in the pulp industry to produce totally chlorine free TCF paper. Paper recycling There are three categories of paper that can be used as feedstocks for making recycled paper: Pre-consumer waste is material that was discarded before it was ready for consumer use.

Post-consumer waste is material discarded after consumer use such as old magazines, old telephone directories, and residential mixed paper. Recycling paper decreases the demand for virgin pulp and thus reduces the overall amount of air and water pollution associated with paper manufacture.

Recycled pulp can be bleached with the same chemicals used to bleach virgin pulp, but hydrogen peroxide and sodium hydrosulfite are the most common bleaching agents.

Recycled pulp, or paper made from it, is known as PCF process chlorine free if no chlorine-containing compounds were used in the recycling process. Virgin paper contains no recycled content and is made directly from the pulp of trees or cotton.

Materials recovered after the initial paper manufacturing process are considered recycled paper. The collection and recycling industries have fixated on the scraps of paper that is thrown away by customers daily in order to increase the amount of recycled paper.

This type of mill detaches the ink from the paper fibers, along with any other excess materials which are also removed from the remaining paper. In the deinking mill, after all of the unwanted coatings of paper are stripped, the refurbished paper is sent to the paper machine.

The old scraps are now constructed into new paper at the paper machine.4. Membership.
