Paper & Cardboard Recycling

History

Paper has a rich and colourful history. It took 3000 years to come up with paper, since the invention of writing, people had been trying to come up with something easier to write on than papyrus or parchment, and also something easier and cheaper to make. In 105 AD, under the Han Dynasty a government official in China named Ts'ai Lun was the first to start a paper-making industry. Ts'ai Lun seems to have made his paper by mixing finely chopped mulberry bark and hemp rags with water, mashing it flat, and then pressing out the water and letting it dry in the sun. Ts'ai Lun's paper was a big success, and began to be used all over China. By 1411 - nearly a millennium and a half after it was invented - people in Germany began to produce their own rag paper. Once they had learned how to make paper, they became more interested in learning about Chinese printing, and a man called Gutenberg produced the first printed Bible in 1453.

High Grade Paper

White, high grade is one of the best types of paper to recycle. Try to keep this type of paper separate when recycling. Although any paper that's been printed on needs to be de-inked before it can be recycled, higher quality paper means recyclers can achieve a higher quality end product.

 

Examples

  • Office paper
  • Copier paper
  • Envelopes
  • Any paper that has gone through the printing process

 

Can Be Recycled Into

It must first be deinked before it can be reprocessed into high grade paper products such as printing and writing papers or tissue.

Mixed Paper

  • Samples
  • Mail- including envelopes
  • Catalogs
  • Magazines
  • Phone books
  • Greeting cards and
  • Wrapping paper
  • Shredded paper

 

Can Be Recycled Into

Mixed paper is recycled to make paperboard and tissue paper. It is also used as a secondary fibre for new paper products or as a raw material for non-paper products, like gypsum board or egg cartons.

Newsprint

Is used in printing newspapers. It is most commonly made with ground wood pulp combined with some chemical pulp.

 

Examples

  • Newspaper

 

Can Be Recycled Into

Some municipalities collect newsprint and shred it for animal bedding

Cardboard

Consists of corrugated containers having liners, jute or craft. Must be free of wax, plastic and boxboard • Corrugated Board

Examples

  • Cardboard
  • Boxes

 

Can Be Recycled Into

Both cardboard and paperboard are recycled into similar products, and may become shipping containers or product packaging

UNACCEPTABLE ITEMS FOR RECYCLING

  • Disposable nappies
  • Plastic lined papers
  • Foil lined papers, Chip Packets
  • Food wrappings, paper towels, tissues
  • Self adhesive post-it notes
  • Cement bags
  • Dog food bags
  • Carbon paper

 

PREPARATION TIPS:

  • Separate your paper waste from your other waste by placing it in the container.

  • Keep your waste paper clean and dry – quality is important for a good end product.
  • Wet paper will not be accepted

 

The Paper Recycling Process at Paper and Cardboard mills.

 

What happens at paper and cardboard mills?

At the paper mill, de-inking facilities separate ink from the newspaper fibres through a chemical washing process. A slusher turns the old paper into pulp, and detergent dissolves and carries the ink away. Next screens remove contaminants like bits of tape or dirt. The remaining pulp is bleached and mixed with additional pulp from wood chips to strengthen it. The watery mixture is poured onto a wire, a continuously moving belt screen which allows excess moisture to drain through. By the time the mixtures gets to the end of the belt, it's solid enough to be lifted off and fed through steam-heated rollers which further dry and flatten it into a continuous sheet of paper. This paper machine produces finished newsprint at the rate of 3,000 feet per minute. Finally the newsprint is trimmed rolled, and sent to printing plants to be imprinted with tomorrow's news. At the mill, the corrugated is pulped and blended with additional pulp from wood chips. Broken, thus shorter and weaker, old fibres are blended with the new pulp to make the medium. Recycled paper fibres and new pulp are blended to make linerboard. Then the medium and the linerboard are shipped to a boxboard plant, where the manufacturing process is finished. The medium is corrugated by specially-geared machines, the linerboards are glued on, and the resulting flat pieces, called mats, are trimmed to size and creased along a pattern of folds. The mats are shipped flat to customers who set them up into boxes. Then the boxes are used to package products for shipping.

Facts

  • Manufacturing recycled paper uses 60% of the energy needed to make paper from new materials.
  • The process of recycling paper instead of making it from new materials generates 74% less air pollution and uses 50 % less water.
  • Recycling 1 ton of paper saves 17 mature trees, 7,000 gallons of water, 3 cubic yards of landfill space, 2 barrels of oil, and 4000 kilowatt hours of electricity
  • A little more than 48 % of all office paper is recycled. This is used to make writing papers, paperboard, tissue, and insulation.
  • Over 73 percent of all newspapers are recovered for recycling. About 33 percent of this is used to make newsprint the rest is used to make paperboard, tissue, or insulation.

 

Our Process

You begin the recycling process when you set apart your used newspaper, paper and cardboard from your household garbage and place it into the bags we provide to you for our weekly collection. We combine your newspaper with paper from other households and sell them to a paper dealer who, because of the volume of material purchased, often operates out of a storage warehouse. The dealer then sells quantities of paper to a user. This is where the actual recycling--manufacturing one product into a new product--takes place.
