UTILIZATION OF WASTE SEED FROM THE TOMATO. 29 
tion to other materials, thereby decreasing the overhead charges and 
adding to the profits already accrued. A plant equipped and oper- 
ated by an association of canners or packers would have sufficient 
waste materials of various kinds from the different canning operations 
to enable it to run throughout the year, thereby reducing the over- 
head charges and increasing the profits very materially. 
SUMMARY. 
It has been shown that the waste from the pulping of tomatoes 
accumulates in vast quantities at the various pulping stations in the 
eastern and middle-western tomato belts. This material is at pres- 
ent entirely wasted, and in many cases its disposal entails consider- 
able expense to the producers. 
Investigation of the practicability of utilizing this waste shows 
that by the application of proper methods the seeds may be separated 
from the waste and made to yield oil and press cake or meal of con- 
siderable commercial value, the former as a table or culinary oil and 
the latter as stock feed. 
From the estimates made on the cost of separating, assembling, 
drying, and crushing the seed, together with the cost of the necessary 
equipment, considerable profit is indicated from an undertaking 
based on the utilization of this waste. 
The most feasible and economical method of procedure apparently 
lies in separating and drying the seed at the various pulping stations 
and shipping it to a utilization center, where the commercial products 
can be manufactured. 
A cooperative plan of manufacture by an association of canners 
and packers of which practically all tomato-pulping concerns are 
members would perhaps be the most feasible method for the prac- 
tical utilization of the waste, not only from tomatoes but from other 
products as well. 
With the growth and expansion of the industry from year to year, 
the returns from an undertaking of this character would be aug- 
mented in proportion to its growth, since the quantity of waste is 
dependent upon the annual output of tomato products. 
The utilization of an agricultural waste of this character for the 
production of commodities of much commercial value is suggested 
as a conservation measure worthy of careful consideration.
