Having proceeded thus far with my subject, the
very important question next arises as to the manner
of the disposal of the house refuse after it has been
collected by the Local Authority, both with regard to
its sanitary aspect and also to that of economy.
So much depends upon the position of every town
and the character of the district in which it is
situated, that no hard and fast lines can be laid
down in reply to this question, if, however, the town
is fortunate enough to be the centre of an agricultural
district, or there are ready and economical means of
conveying the refuse there, no difficulty should be
experienced in disposing of it, if not altogether at a
profit, at least at a small loss upon the cost of collection,
as farmers and market gardeners will readily
buy house refuse at prices varying from sixpence to
three shillings a load to use as a top dressing or
manure upon their land, and a very rich and
fertilizing manure it makes, notwithstanding the
outcry that is sometimes raised against it that it
produces rank weeds, owing to the seeds of such
vegetation being found in every domestic dustbin, the
fact really being that all manures will foster and
help the growth of weeds, as well as cereals or roots,
and the appearance of a prolific crop of weeds points
rather to bad and careless farming than to the use
of inferior manure.
In order to suit the convenience of the customers
for refuse, and in order to prevent any delay in its
collection from the houses, it is necessary for every
town to provide one or more depôts in which the
refuse may be so deposited from day to day as it is
collected.
The site of each depôt should be very carefully
selected, bearing the following requisitions in mind:—
They should not be at greater distances from the
town than would allow the carts to make from three
to four journeys a day, and it is evident that their
position should, so much as possible, avoid the
necessity for the carts to pass through the town when
full; they must also be placed so as to be readily
accessible to the carts and waggons of the farmers,
the customers, and above all, they must be so situated
with regard to any dwelling-houses or public roads
as not to cause any nuisance, or be injurious to
health in any possible manner, and for this purpose
a knowledge of the prevailing wind in that neighbourhood
would be useful, and care must also be
taken that no stream or water-course from which the
supply of any drinking water is obtained is likely to
become polluted by having such an unpleasant neighbour
as a "refuse depôt."
The depôt need only be an open field securely
railed off against trespassers or pilferers, but as it
generally swarms with countless numbers of rats, it
is just as well that no stacks or barns should be
erected in its vicinity, if their owner has any wish to
preserve his corn.
In this depôt, the site of which has been selected
with all due care, the refuse should be made up into
measured heaps, a convenient size for them being
found to be twelve feet square by six feet high; these
heaps are then sold as they stand to farmers and
others who send their carts and waggons to remove
them, thus preventing any possibility of mistake or
dispute arising as to the number of loads each
customer pays for and receives. The refuse, when
first brought into the depôt, is far more bulky than
it afterwards becomes, and it shrinks nearly twelve
per cent. after a few months' exposure to wind and
rain; it is therefore necessary to unload each cart as
it arrives from the town on to an enormous heap or
mound, from the other end of which the measured
heaps are made up after the material has become
stale and sunken. Another cause for the shrinkage
and reduction of bulk of house refuse after reception
at the depôt is the necessary removal of all the old
tins, broken crockery, broken flower pots, &c., before
it can be sold to the farmer, and a very difficult
matter it is to know how to deal with this heterogeneous
mass of absolutely useless articles thus left
behind, unless they can be used for bottoming roads,
or for agricultural or for deep land drainage, or for
filling up hollows of land not afterwards intended to
be built upon, when these materials would be very
useful and acceptable for such purposes, otherwise
they must be kept and allowed to cumber the ground
until some such use can be assigned to them.
All towns are not so conveniently situated with
regard to their surrounding neighbourhood, as will
permit their authorities to sell the collected house
refuse to farmers, market-gardeners, or others, for
use as manure, and in such cases, where they cannot
do so, other measures must be resorted to, in order
to dispose of it in the most economical and sanitary
manner.
Among the numerous questions that I addressed to
the various towns of England when engaged in
preparing the returns to which reference has already
been made, was one to the following effect:—"How
is the refuse disposed of after collection?"
Many and various were the replies to this.
Amongst them were the following:—
In many towns it is stated that the whole of the
refuse is used by brick makers, in others it is simply
"tipped to waste." In one case the answer is,
"Sold by auction twice a year," but to whom it is
sold, and for what purpose, does not transpire. In
some towns it appears to be mixed with lime and
used as manure upon the fields, and in others it is
mixed with the sludge of the sewage farms, and is
then ploughed or dug into the soil of the farm. This
seems a better plan than that of another town, where
it is "given or thrown away," although the difficulty
of disposing of the old iron, tins, &c., is not touched
upon in any of the foregoing answers. The next
reply states that "it is riddled, and the cinders and
vegetable refuse are burnt to generate steam, the fine
dust is used with the manure manufactory (tub
system), the old iron is sold, and the pots, &c., used
for the foundations of roads." In one case the
whole of the refuse is taken out to sea in hopper
barges, and sunk in deep water. In a great number
of towns it is sold by tender for the year, but what
eventually becomes of it does not transpire. But the
most favoured methods, where it cannot be sold as
manure to farmers, seem to be either that of carting
it away to some spot outside the town, and there
using it for the purpose of filling up hollows and
depressions, or that of giving or selling it to brick-makers.
The practice of filling up hollow places with either
house refuse or street sweepings cannot be too
strongly deprecated, as it stands to reason that some
object is in view when these hollows are thus filled
up, and we may be sure that the object is that of
transforming inconvenient and impracticable pieces
of ground into convenient building sites, whereon,
sooner or later, eligible villas make their sudden
appearance, almost with the rapidity of Aladdin's
Palace, under the magic hand of a jerry builder, and
woe betide the unfortunate being who, struck with
the pretentious appearance and low rent of one of
these eligible family residences, takes up his abode
therein, for so surely will disease, and perhaps death,
be his visitor. I will not here enter into the details,
or describe the medical reasons why such sites are
unhealthy for dwelling-houses, as the fact is almost
self-evident, and the practise of using either house
refuse or street sweepings for such a purpose has
been condemned by sanitary experts over and over
again. But I will pass on to describe a method of
disposal of town refuse which is now gaining some
popularity in localities where difficulties are experienced
in getting rid of the refuse by any of the
means to which reference has been made, and which
up to the present time seems to be the best solution
of the difficulty. I allude to the process of the
destruction of the refuse by fire. With this object in
view a Mr. Fryer has invented an apparatus which
he styles a "Patent Carboniser, for the conversion of
garbage, street, and market sweepings, also other
vegetable refuse into charcoal." This apparatus
consists of a structure somewhat resembling, externally,
a brick kiln. It is divided into hopper-shaped
compartments, which at the bottom are furnished
with a furnace, fitted with a reverbatory arch. A fire
is lighted in this furnace, the necessary combustion
being obtained, and the heat maintained, by burning
the cinders, which are sifted out of the house refuse
for this purpose.
All the street sweepings, refuse, garbage, &c., is
then thrown in at the top of the kiln, and it is there
and then completely destroyed by the action of the
fire, and converted into charcoal, which is withdrawn
through a sliding door fixed at the bottom of the
kiln. The inventor further contends that his Carboniser
not only burns everything within it so
thoroughly and completely as to produce effectual
deodorisation, but also that in the process all noxious
gases which may be driven off the burning organic
matters contained in the refuse are themselves burnt
and destroyed.
Mr. Fryer has also patented another apparatus
which he calls a "Destructor for reducing the bulk
for purifying and fusing mineral refuse of towns, the
residue to be converted into concrete or mortar."
This apparatus is somewhat similar in construction
and mode of action to the "Carboniser," except that
it has no tall kiln containing the hopper-shaped compartments.
Great heat is, however, necessary in
order to fuse the mass of heterogeneous articles that
are thrown into it, and its success is greatly dependant
upon such heat being constantly and efficiently maintained.
It is said that the cost of an establishment
to dispose of the refuse by this means, consisting of
one six celled Destructor and an eight-celled Carboniser,
boiler, steam engine, mortar pans, cooler,
chimney, shaft, and buildings, is about £4,500.
Each cell is stated to deal with about 50 cwt. of
refuse in every twenty-four hours, and that no
nuisance is experienced in the vicinity of the depôts.
This apparatus has, I understand, been adopted in
Kralingen, Leeds, Blackburn, Bradford, Warrington,
and Derby, and is about to be adopted in other
important places.
It is not my intention here to describe or to discuss
the question of the collection and disposal of night
soil, which in many towns is intimately connected
and amalgamated with the collection of house refuse
and the cleansing of streets. It is a subject of
sufficient importance to be dealt with separately.
The following particulars, however, with reference to
the collection of house refuse in connection with the
pail system at Manchester will not be out of place,
especially with regard to the reference which is made
to Fryer's Carbonisers and Destructors, and it must
be borne in mind that the refuse here spoken of is
wet, which makes the difficulties connected with its
destruction by fire greater than it would be if only
dry, or comparatively dry, house refuse had to be
destroyed. These particulars are gleaned from a
report contained in a copy of the British Architect,
of 1876, of a visit by the members of the Manchester
Scientific and Mechanical Society to the works of the
Manchester Corporation Health Committee, the
figures being altered so as to conform more closely
with the growth of the work since that year.
There are about 56,000 closets in Manchester,
44,000 of which have been constructed on the cinder
sifter principle, and are emptied during the day, the
remainder are emptied during the night.
The contents of the new closets are brought away
by vans specially constructed for the purpose, having
five compartments, one of which is open and uncovered,
and this receives the dry refuse; the other
four compartments are covered and enclosed with
tightly fitting doors. Each of these compartments
holds six galvanised iron pails, which are also
covered with closely fitting lids. The van bottoms
are panelled, and the inside of each panel is filled
with a layer of carbolic acid powder, one inch thick,
and they are thoroughly cleansed after each journey.
The Health Committee employ 100 of these
vehicles, each one making four journeys per day.
The contents of the closets which are emptied during
the night are taken away in open carts, two-thirds to
the tips and the remainder along with the refuse
brought into the yard by the vans, is sent each night
into the country.
The amount of material dealt with each week by
the Health Committee is about 3,000 tons, and may
be described as follows:—Paper, 1 ton; rags, 3 tons;
dead animals, dogs, cats, rats, mice, guinea pigs, &c.,
2 tons; stable manure, 17 tons; meat tins, old tin
and iron, 33 tons; refuse from slaughter-houses and
fish shops, &c., 60 tons; broken pots, bottles, and
glasses, 80 tons; vegetable refuse, door mats, table
covers, floorcloths, old straw mattresses, 100 tons;
fine ashes, 1,230 tons; cinders, 1,400 tons.
The Committee employ in this department over 500
men, including clerks, inspectors, wheelwrights,
smiths, saddlers, tinmen, engineers, mechanics,
manure and mortar makers, stablemen, and
labourers. They have 156 horses, and about the
same number of vehicles of various descriptions.
When the loaded vans reach the yard, they are
first weighed, afterwards they are taken on to the
first floor of a two-storey building, where the dry
refuse from the open part of each van is unloaded
and shovelled on to sieves worked by steam power.
By this arrangement the fine dust widely diffusing
itself in its descent, falls on to the floor below,
covering the contents of the pails, which are, at the
same time, being emptied on to grids fixed in the
floor. At one end of these grids the bars are set
much more closely together than at the other, and
serve to convey the liquid portion of the contents of
the pails by means of troughs to a tank where it is
further dealt with. The solid portion of the excreta
falls through the wide-barred portion of the grid into
suitable receptacles. The rough portion of the dry
refuse, after being separated from the fine, is carried
along a movable and endless table to the mortar
mills, the boiler, or to one of the various furnaces, of
which there are several in the yard. This dry refuse
is of such a heterogeneous character as to require
various modes of treatment. It is made up of paper,
rats, meat tins, straw, cabbage leaves, onions, apples,
turnips, fish bones, dead cats, rabbits, guinea pigs,
fowls, brush heads, old boots, old books, knives, forks,
spoons, children's toys, old hats, old bonnets,
crinoline wires, umbrella frames, broken pots, broken
bottles, preserve jars, medicine bottles, old mattresses,
cinders, bits of coal, firewood, bass, broken bricks,
and a host of other articles too numerous to mention.
When this mass of rubbish is somewhat assorted, the
cinders are separated and used for fuel for the boilers
and furnaces (no coal whatever is allowed in the
yard), the remaining portion of the rubbish along
with some most vile and abominable matter which
occasionally comes to the yard in the pails, is taken
to the Carbonisers (of which there is a nest of eight
in the yard), and the obnoxious material is therein
carbonised and is resolved into a perfectly harmless
material.
In another part of the yard is a second set of
furnaces which are called destructors, and are used
for the purpose of destroying rubbish, which before-time,
for many years past, has been deposited in
large heaps in every suburb of the city, to the great
annoyance of the inhabitants whose fate it was to
live in the vicinities of these deposits. These
destructors not only consume this objectionable
material, but they furnish heat to a concretor which
is placed in close contiguity. The spent fuel is
carted to the mills, and is there converted into
mortar—a mortar, too, of the best description—as
the samples of brickwork built with it and exhibited
abundantly testify. This concretor, which is driven
by steam power, is a large cylinder of a peculiar
internal construction, which exposes an extensive
evaporating surface to the heat from the destructor,
which passes through the cylinder from end to end.
The work of this concretor is to subject the urine or
liquid portion of the contents of the pails fed by
means of the troughs already spoken of in connection
with the tank. The urine is pumped from this tank
into the concretor at the rate of about 150 gallons
per hour. The concentrated urine, which contains a
large quantity of ammonia, is mixed with two-thirds
its weight of charcoal, and the composition forms a
most valuable manure.
The carboniser, the destructor, and the concretor
have all been invented and patented by Mr. Alfred
Fryer, of the firm of Manlove, Alliot & Co., engineers,
Nottingham. The process of carbonising is patented
by the Universal Charcoal Company, Limited, who
are to receive a royalty, we understand, from the
Health Committee for the use of their patent. There
is a tall and noble-looking chimney in the centre of
the yard surrounded by many new buildings and
sheds, and this has been built with the concrete
mortar manufactured by the Health Committee.
Such is the gigantic scale upon which these matters
are dealt with in the City of Manchester.
The other methods, to which reference has been
made, for the disposal of town refuse require no
further comment, as it is evident that unless a ready
sale for the refuse can be effected, by far the best
method of disposing of it seems to be that by which it
is completely annihilated by fire in the manner that
has been described, or in some other similar manner.
Having thus far followed the house refuse from its
first appearance in its cradle, the dustbin, through
its chequered career after collection down to its
decease, either by burial, or by cremation, the
question of the cost of the whole of this work must
be deferred until the final chapter, after I have dealt
with the subject of street sweeping and cleansing, the
removal of snow, and a short chapter upon street
watering, which is somewhat analagous to scavenging,
and is frequently included in the accounts of that
work in the estimates which are prepared by a Local
Authority.
