WASTE PRODUCTS,
Industries That Prevent the Waste Of
Refuse stuff.
[POlVtnchnic ReVieW.

The glycerine industry, which has obtained
colossal promotions is O. notable Illustration
of q great manufacture based entirely upon
the saving of @ product that until lately was
O. waste result with the soap boiler. Even
more important in magnitude, we may estl-
mate the industries connected with man
ufacture of the aniline colors and artificial
aIisarine from the refuse coal tar that was
gas works. The waste blood of the abattoires
IS sought after by the sugar reftner and the
manufacturer Of albumen. Old boots AMI
shoes and leather waste are turned to good
account by the chemical manufacture in pro-
ducing the cyanides ferrO and ferri cyanides,
SO Indispensable in color printing and pho
Biography. Sawdust mixed with blood OF other
aggIutinative substance, and compressed
by powerful pressure, IS moulded u +h ana
sand decorative and useful articles; or as 1s
the case too, with the spent tan Of the tan
neries and the spent bark OF the q yeWorks, It
is utilized for fuel. Oyster shells, OF which
our barbarous ancestors made the. shell
mounds that delight the soul OF the archmolo-
gist are burned to lime. The waste of lin
seed oil manufacture is eagerly sought for as
| food for CATTLE The waste ashes OF wood Tires
are eached for potash. River mud is min
| gled with chalk burned and ground to make
| the famous Portland cement and the ruthless
| hand of utilitariansm has not even spared
| the brckbat, that from time immemOrlal has
served to crack the heads Of opposing fac
lime. The finest glue size is made OF
the waste Of parchment skins. The waste
| gases of the blast furnaces are now EN-
| ployed to heat the blast, to generate the
steam that drives the engine that makes
the blast, to hoist ores, machinery, etc; and
! even the Stag that had for years served to
decorate the hillsides, is cast into building
and paving blocks, graduated for buil,ding-
sand or ground for cement, mixed with ap-
propriate chemicals, and made into the com
mon grades of glass, or blown by q steam Jet
! into the finest tilaments to form the curious
mineral wool used largely as a heat insulat-
ing protector upon steam pipes, boilers, roofs,
etc. SO, too, the enormous hills OF anthracite
| cOal-dust that have for years borne silent
testimony to the crudty OF our methods OF
coal mining, bid fair to disappear in time be-
meath the boilers supplied with ingenious
fuel. HEven the anthracite itself but a
| few years ago was q black StOne unap-
preciated and useless. The waste heat
of the lime kiln Is made to generate
steam and warm immense public buildings,
| and the Exhaust" OF the steam engine must
do duty in heating the feed water instances
like the aboveucoud be multiplied almost in
definitely to demonstrate how Invention has
enabled us, with the most beneficial results,
| to reap advantages where none were sup
posed to exist or where, il they were sus-
! pected, they were undervalued or unavailable,
or simply neglected. And now, having en-
| deayOred to illustrate what modern Invention
has done and is doing in the direction OF
utilizing waste products OF nature Or those OF
the Industrial arts, we shall be prepared TO
consider the question whether there are not
waste forces of nature that can and should be
turned to useful account, and whether we are
! not guilty Of tho crime OF naglenting to avail
ourselves of eXhanStleSS and incalculable
stores of power that could be made do our
bidding.
