Recycling It's often learned that recycling is able to use the paper used once as paper again.
Surprisingly, a wastepaper is used for more than 60 percent of the raw material with which paper is being made in Japan.
The wastepaper which can be used for recycling often lays eyes on corrugated cardboard, a magazine, a newspaper and a milk pack, and there is a mark called a recycling mark in many cases on those.
A recycling mark is the distinguishing mark which promotes the collection by type which is shown to container wrapping which became "designation indication product" based on "recycling law". "Designation indication product" is the product which can be reused as resources when it's collected by type when some products were disposed of, and this mark is used as the mark.
A carton recycling mark and a corrugated cardboard recycling mark also correspond to various kinds of resources in addition to the paper recycling mark.
When such resources are collected, and it's recycled, magazine kinds will be also a raw material of corrugated cardboard again in a raw material of corrugated cardboard and cardboard for corrugated cardboard.
Newspaper will be also a raw material of newspaper and printed information paper again, and a milk pack is recycled by something close such as toilet paper and a tissue. Professional traders and supermarket are being performed, so isn't these collection learned about well?
Then let's see how new paper is made from used paper.

First a collected wastepaper is put in the blender water entered together, it's stirred round, fiber is disentangled and it's made pulp.
This work is called “disaggregation".
Next the "removal of dust" which takes trash and an alien substance from old pulp and paper is performed. It's "removal of ink" to do in the 3rd.
To take ink from old pulp and paper to this work, it's washed using medicine.
Made pulp is to here and it are pulp and called gray pulp bleached cloth-less, so when "sarashi" is made last by medicine, bleached cloth pulp and called white pulp will be completed.
A wastepaper can be reborn in a paper raw material by these 4 processes.
But medicine is used in quantities in this a series of work and a machine is let through many times, so to take impurities as much as possible the quality of fiber has dropped and it becomes fragile.
I think we find out that you can't produce paper excellent in quality hard as well as recycle's of a wastepaper taking serious time and effort this.
Even if I tell a bite to have been above-mentioned with recycling, it's also fact that there are various problems as well as a thing gentle with the environment. Let's think about the problem which has happened at present while sailing up history of wastepaper collection.
It's thought that the scripture was being reused wastepaper recycling started from the Heian Period in Japan, and when repealing a scripture of the those days.
A collecting cargo trade of a wastepaper was also begun in the Edo Period, and a wastepaper was called "the scrap paper" the time.
This business has history in Japan, but also to handle a wastepaper as goods from the old days, the one I ask for an offered consideration is general even at present.
I'm falling the situation to which the wastepaper usage rate says the wastepaper price slumps for 50 percent and the consumption to stagnate, and that the collection form of the traders falls in spite of but collection's of a wastepaper taking the cost of the transport costs and the personnel expenses.
The price by which petrol consumption of the car which is also used for collection in these other ones again is a wastepaper more highly and therefore than the thing which increases and production cost of a recycled paper produce completely new paper, it rises, a problem has been also caused.

Problems of a recycled paper
It's said that the recycled paper which reuses and makes a wastepaper is good for the environment, but when it's judged by the side as the global warming actually, there is a problem.
When making a recycled paper using 100% wastepaper, when recycling, it's said that it's larger in the quantity of discharged carbon dioxide than the amount of emission of the carbon dioxide which is discharged when making new pulp.
Of the number of process until that makes paper, it's said that it takes the carbon dioxide amount of emission for the cost which increases to be different.
When making paper with new pulp, something as black liquid goes out by the process.
This black liquid can be used as the biomass energy source when making paper.
When making paper with new pulp, so almost no fossil fuel is used.
It also depends on kind of trees, but absorbency index of carbon dioxide will become worse in nearly 20 years after it's planted.
So felling the tree and making new paper, and when planting a new tree, it's said that it's also good for global warming.
But many fossil fuels are necessary because this black liquid doesn't occur if it's in case of a recycled paper, and the tree which didn't absorb carbon dioxide more any longer is also left.
That it's gathered,
・100 % of wastepaper→The forest doesn't absorb CO2 is protected, but a fossil fuel is consumed.
・New paper→ The forest absorb CO2 as well as there is also little consumption of a fossil fuel.
Said, it'll be.
