12 COMMISSION OF CONSERVATION 



APPROXIMATE COSTS 



The following description of the plant required and statement of 

 approximate costs in manufacturing fish waste into stock food and other 

 useful products was obtained from Mr. J. B. Feilding on February 21, 

 1918. The figures relating to costs are approximate only and the Com- 

 mission of Conservation does not hold itself responsible for their accuracy. 



I. PLANT 



There are three distinct processes of manufacturing fish waste into 

 fish meal, viz., (a) the continuous, (b) the solvent, (c) the intermittent. 

 The intermittent process does not destroy the food values of the material 

 and is most suitable for the manufacture of feed in Canada, although it 

 has never been used on the Atlantic coast. 



Intermittent Process: The plant for manufacturing by the in- 

 termittent process consists of an engine, boiler and several digester units : 

 Digesters can be had in any capacity from 2 to 6 tons each, but those 

 with a capacity of 4^ tons are most economical. 



The minimum-sized economic plant consists of 2 digester units and 

 will treat 32 tons of fish waste in 24 hours. It can be erected anywhere 

 in Canada, less duty and freight, for approximately $18,000 to $20,000. 

 This does not include the cost of the building to house the plant, 

 which would cost from $8,000 to $10,000 additional. 



The same engine and boiler would carry an additional two units, 

 each of which would cost from $4,000 to $5,000, f.o.b. point of shipment, 

 but exclusive of the cost of installing and connecting. 



Oil Refining Plant: For refining the oil produced, a filter press, 

 an autoclave, a scourer, a cod-liver-oil outfit and a few sundries, are 

 needed. Such a plant would cost $4,000 to $6,000, and it would cost 

 12,000 more to erect it. 



Plant for Compounding Stock Food: All that is needed for this is 

 a good mixer, bagger and weighing machine costing, say, $1,000 alto- 

 gether. 



rM^Summary: The foregoing estimated costs may be summarized as 

 follows: 



Digester plant $18,000 to $20,000 



Building for same 8,000 to 10,000 



Oil-refining plant 4,000 to 6,000 



Building for same 2,000 to 2,000 



Compounding plant 1,000 to 1,000 



Total estimated cost $33,000 to $39,000 



II. MANUFACTURING COSTS 



Cost of operating a 2-unit plant for 12 hours: 



16 tons of fish waste at $2.00 $32.00 



Labour: engineer at $7.00; 2 labourers at 



$2.50; and 1 boy at $1.00 a day 13.00 



Coal: 4 tons at $10.00 40.00 



Depreciation 5.00 



Incidentals 5 . 00 



Total cost of treating 16 tons $95 . 00
