1 . backgroundPaper
is one commodity that is needed by almost all people in the world , our
modern life everyday now can not be separated from the paper that most
of the wood raw material harvested from the forest trees . Thus the more extravagant use of paper , the more trees to be cut down for pulp ( pulp ) paper candidate . As a rough idea , to produce 1 ton of original fiber chemical pulp timber takes about 1.5 tons . So imagine if the use of paper can only be met by the native fibers will have a direct impact on environmental sustainability .Paper demand in Indonesia when in 1987 it only requires 782 420 tonnes in 1996 has reached 3,119,970 tons . And
of all paper consumed is only a small part back to the manufacturer for
recycling because of conflicts of interest with other uses by the
public . However, it does not mean that the paper does not go back to the paper mill is fully utilized by the public . Waste
paper that is not utilized due to one reason or another will eventually
lead to the final disposal ( landfill ) that will increase the volume
of waste and shorten the life of the landfill itself.
2 . Recycling Waste Paper / CardboardRecovery of waste paper directly to other uses is an effort to increase savings in paper demand of the original fiber . Efforts to re- paper the former will have a positive impact on future forest extinction .One
waste paper recycling effort is to give the treatment of paper
cardboard products packaging materials to be used again with the same
size or smaller . Things
to consider is the type of query boxes usually have a uniform type of
wave , ie a wave cardboard ( one ply ) , wave 2 ( two plies ) , etc. . Besides, it should not be pressed cardboard waves because the waves will be lost and reduces the strength cardboard itself. Outline picture of the treatment of the cardboard used is as follows :
