Paper consumption• Typically paper made of cellulose
pulp which driven from wood.• World wide consumption of paper
has risen by 400% in the past 40 years.
• 35% of harvested trees are being used for paper manufacturing.
• Where about 10% of this wood are from old growth forests

Paper consumption
One large tree could provide supply of Oxygen for two people.

Paper consumption
World wildlife fund
• 400 million tons/year is the global paper consumption of 2010
• Almost half of this is consumed by Europeans and North America.
• U.S. annual pulp paper consumption exceeds 110 million tones per year.
• Which consuming 1 billion trees annually from an area of 12’400 Sq. miles approximately every year.

Paper waste and recycling

• The production and recycling of paper has numbers of adverse effect on the environment.
• In the cleaning process, despite the water is being treated after use, soil is being contaminated.
• In the deinking process the water use is being mixed with soap-like chemicals called surfactants, producing sludge which need to be burn on 800c to be reused.

Paper waste and recycling• Bleaching process (whitening process) using elemental
Chlorine, which release into the environment large amount of Chlorinated Organic Compounds.
• This Dioxins are recognized as a persistent environmental pollutant, Carcinogenic, and highly toxic for soil & water.

Paper waste and recycling
U.S. Environmental Protection Agency. 28 April 2007
• U.S. alone produce 71.6 million tons of paper waste per year, which accounts to 40% of the total waste.
• A bale of paper to be recovered, is not totally paper, 20% of it contains: staples, paper clips, plastics.
• 35% of the rest 80% of the bale is the paper sludge comes out from the cleaning and deinking process.

Paper waste and recycling
Paper university 2007
• Accordingly, only half of the recycled paper produced as new paper, noting that America recovered nearly 50% of its total paper waste.
• Beside deinked pulp paper is not as strong nor as bright as paper made from virgin pulp.

Despite the advent of the “Digital Age” and the paper recycling use increased, Earth loosing about 13million
hectares of wood per year.

Tree-free Paper• Tree-free paper made from
alternative raw material composition used instead of wood-pulp paper.
• It’s claimed to be more eco-friendly because the source of fiber’s entire life used is less than 10 years.

Tree-free Paper• Source of fibers:
Agriculture residues like sugarcane bagasse, husks, and straw.
Wild plants such as Bamboo, kenaf, hemp, and flax.
Textile waste.
**No need to recycle the sugarcane paper because it could be used as composite for soil, it doesn’t need chemical treatments.

Explain to the future generations, it was good for the Economy… when
they can’t farm the land, breath the air, nor drink the water.
