To a certain degree the action is automatic, from the simple circumstance that supplies are strictly limited. Money does not constitute such a determining factor to-day as was the case five years ago, although of course it still exercises a far-reaching influence. But the mere fact that an adequacy of raw materials cannot be procured merely because one may be disposed to pay fictitious prices, is stimulating interest in the waste issue to a degree which, under conventional conditions, would never have obtained. In times of plenty one does not pause to consider for a moment as to whether it is worth while to devote any time and energy to the exploitation of a certain refuse.

But the great question is one not so much concerning what we can derive from wastes, but whether we have really digested the lessons which the enemy has taught us. On every side we see startling evidences of what he was able to do by scientifically turning over and using the rubbish-heap, and the great wealth he was able to acquire by following such practices. We found ourselves hit at every turn and, in the hope of solving the critical situations which arose, were forced to follow the enemy’s example and become a nation of chiffonniers. We have acquired wealth in the process, have discovered the value of the mine which the junk pile represents, and realize that more wealth still remains to be extracted from such untapped resources.

We have also become intimately conversant with what may be described as the most perplexing phases of the problem, the greatest of which is the segregation and collection of the residues. It is upon this rock that all future effort regarding the scientific exploitation of waste, in these islands at all events, is in danger of being wrecked.

The mere description of what we ourselves cannot use in the course of our operations, as waste, or rubbish, invests the project with a dangerously false atmosphere. Being regarded as worthless there is a tendency towards the opinion that its collection and segregation should be conducted along honorary lines. This is a precarious policy, because it repudiates the fundamental law of the labourer being worthy of his hire, whether it be in ploughing, the smelting of steel, shipbuilding, or the collection of waste.

Simultaneously another immutable law is being flouted. All matter, irrespective of its character, which is capable of being considered as a raw material, must command a market value. It may be high, or it may be low, but the fact remains unchallenged that it possesses a certain intrinsic worth. Refuse, which can be worked into something useful, is just as much raw material as a shipload of ore, or a consignment of gold. It is its mere classification as waste which imperils its commercial significance. This is demonstrated by the sudden importance and value it instantly commands when it becomes labelled, not “waste,” but a by-product.

In these circumstances, therefore, it would represent a decided progressive step if a recognized market could be established in waste products. By so doing all residues could be given accepted commercial values with which one and all might become acquainted by perusing quotations, in precisely the same way as the movement in the prices of raw materials may be followed by reference to the daily or weekly market lists. Until such time as wastes become so recognized the uncertainty of supply must obtain, because it is the very ignorance of the subject which contributes to the loss of such material through fire and other equally destructive measures with its appalling loss of wealth.

The establishment of a market price for all and every description of waste would act as the direct incentive to preserve anything and everything for further possible use. This was proved very conclusively during the war, when bones and paper were in such urgent request, the one for the reclamation of the fat, and the other for re-pulping. Under normal conditions both wastes had received indifferent consideration, and immense quantities of the two materials suffered complete useless destruction by fire. The premium placed upon the price of bones was only ½d., or 1 cent, a pound, the butcher being regarded as the collecting medium. That is to say the bones would be paid for at the above rate upon surrender to the butcher. The reward was not high, but it proved to be sufficient to induce people to husband their bones and to dispose of them in the recognized market. It was the same with paper. The average housewife devoted but little attention to the harvesting of this waste until she learned that the authorities were ready to pay 1d.—2 cents—at least per pound therefor through its accredited agents. Instantly she commenced to display thrift, and was somewhat surprised by the money which could be picked up in this manner. Yet it is safe to assert that had no financial value been placed upon these wastes barely 50 per cent. of what was actually secured would have been forthcoming.

Unfortunately there is a large class of waste exploiters which is disposed to trade upon the ignorance or indifference of the community. In the knowledge that the average house, office and factory has no conception of the value of its refuse, or is ready to part with it for nothing because it is regarded as a nuisance, the waste merchant is disposed to become discriminatory and autocratic. He is perfectly ready to acquire what he knows full well possesses a distinct value so long as he can get it for nothing. The moment the owner sets a value upon the flotsam and jetsam the waste merchant will have nothing to do with it. He assumes an indifferent if not a dictatorial and impossible attitude to which the second party to the projected bargain takes immediate exception. The upshot is that sooner than part with the material for nothing, and in the knowledge that the acquirer is certain to sell out in turn at a profit, the material is withdrawn completely from possible circulation, and so suffers irretrievable loss. To barter is human, and this applies as forcibly to waste as to houses, commodities and produce in general.

The waste market must be set upon a firm and solid basis. Those who have specialized in this field of trading during the past few years, and, as a result, have become acquainted with its possibilities, and the true value of such material as is to be obtained through the devious channels, are in the position to effect such a reform. The price of waste is naturally subsidiary to the fluctuations in the market quotations of the materials whence it is drawn, as well as of those normally employed in the industries to which waste may be applied. The general conditions are decidedly more complex than those prevailing in the handling of straight materials, for the simple reason that then only the one market needs to be watched.

Factors of cost also require to be closely followed. In the true economic and scientific exploitation of all waste products the question of cost is vital. It may easily jeopardize such utilization. Naturally a margin of profit must be available from the working-up of the material, not only to ensure its use, but also to safeguard the sources of supply. This margin must be determined, not on the top of the market as is the case at the present moment when conditions are abnormal, but when prices for raw materials are at their minimum. If, then, the exploitation of waste can be conducted in such a way as to compete successfully with ostensible raw materials, recovery must hold its own to become more and more profitable as the market rises. By-products can be exploited only so long as the cost of preparing them for commerce proves profitable. If it should become cheaper to treat raw materials for a similar article then waste reclamation must suffer abandonment, except in those rare instances where every contributory source of supply must be pressed into service. Such conditions rarely obtain on a low market, because the latter is directly attributable to the circumstance that supply is in advance of demand. It is the inversion of this law which forces high prices.
