The straw, borne directly from the land, is relatively cheap. The
cost, delivered to the mill, even during the war was only about £4
10s.--$22.50--per ton. This figure is likely to fall. It produces
an excellent paper, but it is essential that it should be chopped
very finely preparatory to treatment, after which it is boiled with
chemicals and finally bleached. The yield efficiency being 33·3 per
cent. it follows that three tons of straw are required to produce one
ton of paper.
But the straw is not only required for the production of paper; it
is equally necessary for the manufacture of strawboard. Under war
conditions an appreciable quantity of the reclaimed paper was being
repulped to furnish cardboard and paper-board for packing purposes
to make good the shortage prevailing in regard to the Dutch product.
But the waste-paper is more useful for paper-making. Accordingly it
is being switched over to this duty. It was merely utilized otherwise
during the war because it was so urgently required, the national
consumption running into approximately 100,000 tons annually. Efforts
are being made to establish the strawboard industry in these islands.
The Dutch method has been adopted, and there are hopes that the output
will be speedily raised to 50,000 tons a year. While this falls far
short of the actual imports it represents a bold commencement to
emancipate us from the necessity to pay tribute to the foreigner to the
extent of nearly £1,000,000--$5,000,000--per year for an article which
we might just as well produce at home.
Why do we not undertake the manufacture of wood-pulp in this country?
This is an obvious question. But so far as these islands are concerned
the absence of supplies of raw material in the form of forests has been
responsible for the British abandonment of this range of activity.
Anterior to the outbreak of war there were three mills in this country
possessing integral facilities for pulping wood by the sulphite
process, but it was unremunerative owing to the insufficient supplies
of suitable indigenous timber. Two mills permitted their sulphite
plant to fall into disuse and in course of time dismantled them. The
third mill maintained operations, though under difficulties, while its
contribution was small in comparison with that of Scandinavia, its
capacity being only 6,000 tons a year.
