However, for residents of India 1,5 kg of paper is enough per person a year and residents of Afghanistan and Mali use only 100 g. Opposed to the USA and Finland where sales of paper products decline from year to year, in Russia these sales are stable and even grow – approximately they’ve grown on 1 mln tons within 8 years. Russian industry with production volume of about 8 mln tons fully covers internal needs in paper and cardboard, exporting abroad over 2 mln tons. The same amount of paper is imported. In Russia operate 25 pulp-and-paper mills, each working place on them provides 10 working places in neighboring fields.
World record on paper folding belongs to American woman Britney Gallivan. In 2002 she – the only one in the world – not only folded paper strip 12 times, but also created mathematical justification for the process of double folding.
To produce 1 ton of paper from secondary material you need approximately 4000 kWh of electric energy. It is comparable with annual energetic consumption of an average family. However, it’s twice less than you need to produce the same amount of paper from pure cellulose. And harmful emissions into atmosphere reduce in this case on 70%. In Japan up to 60% of paper is produced through recycling. In Russia so far less than 1% and this indicator grows very slowly.
No scientific reasoning exists to explain why annual consumption of office paper consistently grows though electronic document flow and e-mailing is implemented more and more. Record on paper use belongs to officials, lawyers and financial specialists. One worker of this type annually uses (if we count in trees) 17 coniferous trunks.
Use of printers with double side printing allows saving office expenses on paper up to 35%. However the largest amount of paper is used not to print documents and graphic art, but for packaging and boxing.
Paper is produced from wooden cellulose received from all types of wood. From soft wood of cedar, pine and fir produce rougher and stronger packaging paper. And from hard types like oak or maple less strong, but smooth paper for polygraphy and office needs. Mixture of oak and pine wood and special treatment allows getting firm and elastic paper to print books.
You can eat paper without making any harm to your health. On 85% it’s comprised of cellulose which is a complicated carbohydrate with glucose. Calorific value of paper is comparable with potato.
Chlorine was first applied in production sector to make cellulose white. Before that paper color was grey-brown.
You can easily cut yourself with a sheet of paper as it’s the same as razor blade, its thickness is about 100 mkm.
The first paper money appeared in China in the beginning of IX century A.D. In 1769 paper money in Russia were introduced by the empress Catherine II. Today all over the world paper money are being replaced by plastic ones. They are more durable, they serve about 3 years instead of 6 months, and they are more ecologically-friendly and hygienic. In order to issue polymer currency you need less productive capacity and it’s easier to recycle plastic money when they are withdrawn from commerce, than paper ones.
Over 400 types of paper and cardboard exist in the world. From them, besides traditional polygraphic production and packaging, produce a lot of diverse goods that look like as if they are made of paper. Among them: furniture, gypsum plasterboard, laminate, insulating materials for car capacitors, fibrous filters and many other things.
