While it is only within the past few years that the possibility of
reclaiming oil from cotton-waste has aroused such earnest attention,
it must be acknowledged that many firms sought to reduce their
expenditure by submitting their cloths and waste to a laundrying
process. Of course, by this practice the textiles were recovered, but
the oil was lost, while material expense was incurred in the conduct of
the laundrying operations and the acquisition of suitable detergents.
An interesting record of the cost of the respective processes is
forthcoming from a certain firm in the South of England. It refers to
two years’ operations, the one referring to straight laundrying of the
sponge cloths and waste, while the other refers to the latest method
of dealing with such materials. Under the former _régime_ the cost for
the year was £219 9s. 2d.--$1,097.28. The heaviest items were for the
purchase of sponge cloths and waste, the figures for which were £62
17s. and £137--$314.25 and $685--respectively. The cost of washing the
dirty cloths at 7s. 3d.--$1.78--per week was £18 17s.--$94.25.
The firm then acquired a small oil reclamation and cloths-cleaning
plant at a cost of £125--$625. During the year, under the new
conditions, the expenditure on account of sponge cloths and waste
was £25 16s. and £85 15s.--$129 and $428.75--respectively, but, for
purposes of comparison, one-fifth was added to each item to counteract
the slackness encountered, and to bring the subject more in line with
the experience of the previous year. But even after making these
allowances the total expenditure for these two articles came out at
only £133 17s. 2d.--$669.28--against £199 17s.--$999.25--when the
textiles were laundered. Inclusive of all expenditure, including wages,
washing materials, power, and interest at 5 per cent. upon the first
cost of the plant, the total cost was £199 4s. 4d.--$996.8--as compared
with £219 9s. 2d.--$1,097.28--for the previous year--a saving of £20
4s. 10d.--$101.20. But under the new system 716 gallons of oil, totally
lost under the previous method, were reclaimed, which represented £11
15s.--$58.75, so that the total saving was £31 19s. 10d.--$159.98,
representing approximately 25 per cent. on the capital outlay incurred
for the installation of the plant.
