Based upon wood, a natural renewable resource, paper is both biodegradable and recyclable. It is made up of many fibres that are interlaced and compacted in a web-like fashion.
Millions of tonnes of paper are produced each year. This is used for a wide variety of products and applications such as office paper, newspapers, envelopes, agricultural sacks, plasterboard and the packaging of all types of consumer, commercial and industrial goods.
Making new paper from old paper uses 30% to 55% less energy than making paper from trees and reduces related air pollution by 95%.
Recycling one ton of paper typically saves about 6.7 cubic yards of landfill space. A cubic yard of stacked office paper weighs about 380 pounds. Cost savings may be estimated by multiplying the tons recycled by 6.7 times the cost per cubic yard for waste disposal (if by volume) of by cost per ton (if by weight).
Commercial and residential paper waste accounts for more than 40% of waste going to the landfill. Eliminating this paper from our waste would nearly double the lives of current landfills.
Newspaper is recycled into newspaper, game boards, egg cartons, gift boxes, animal bedding, insulation, and packaging material.
Office paper is recycled into office paper, tissue paper, paper towels, and toilet paper.
Corrugated cardboard is recycled into new cardboard and cereal boxes.
Resources Saved Per Ton of Paper Recycled17 trees
275 pounds of sulphur
350 lbs of limestone
9,000 lbs of steam
60,000 gal of water
225 kilowatt hours
3.3 cubic yards of landfill space
I hope this can help with your understanding. =)
