Energy embedded in materials employed for vegetable canning was studied. The materials studied were vegetables, packaging materials, water treatment chemicals, and processing equipment. Data on energy use for vegetables, packaging, and water treatment chemicals were dorived from published sources. For process equipment a new method, based on data of the Bureau of the Census, was devised. It is more specific and reflects recent energy use data. Its results compare favorably with those of Herendeen. For the one cannery's inventory of the various materials, the indirect energy (k cal) inputs per case of 1‐lb cans (24/303) were: 8,157; 36,466; 641; and 207, for vegetables, packaging materials, water treatment chemicals, and processing machinery, respectively. Earlier, the direct energy use in the cannery was determined to be 17,589 k cal per case of 1‐lb cans.
