The Slop Bucket
Long before anyone had heard of conservationists, American households made use of everything. Rags were woven into rugs. Straw was dried for bedding. And the meager leftovers of cooking and eating were meticulously carried into the porch or the yard and scraped into the slop bucket, to be fed to the pigs before bedtime.
The Emerson Electric Company's so-called pig pushed waste into a ring where it was ground and flushed down the drain.
