Karter was one of the leading innovators in materials recycling and the first to engineer a "replicable system for mixed recyclables." 
Personal life, education, and early career
Karter was born in Chicago, Illinois and died on March 30, 2010. He was a graduate of Morris High School (Bronx, New York) and of the United States Military Academy at West Point, and of the graduate school of engineering at Harvard University. Karter, the son of Greek immigrants, spent part of his childhood in Anavryti, Greece, and but his school years in the United States.
Karter was a freshman at City College of New York when Pearl Harbor was bombed. Upon entering the Army he took a series of exams. One qualified him to be parachuted into Greece to work with the partisans. The other qualified him to be appointed to West Point where Congress had authorized an expanded Corps of Cadets to supply trained officers for a war that might prove lengthy. Karter served for a time in England before beginning West Point. He graduated with the class of 1947 and served with the Army of Occupation in Germany where he met his wife, Elizabeth Carmen Whitman, who was serving with the US Defense Department Army Special Services, a USO-like organization. The Elizabeth B. Karter Watch Rock Nature Preserve in Old Lyme is named in honor of Karter's late wife.
Karter also served in Korea, and in Corps of Engineers flood-control projects in the United States. The Army sent him to earn a M.S. in nuclear engineering and physics at Harvard. He was serving as an instructor at West Point when his term of service ended in 1957.
In the wake of the enthusiasm for recycling that swept the nation following Earth Day (1970), many communities set up recycling programs that required householders to drive their cans and glass bottles to a recycling depot, sort the glass bottles by color, and throw them into large metal containers. Karter invented and patented industrial processes capable of sorting cans according to their metal content, and of sorting glass into colors and mechanically crushing glass (a highly abrasive substance) economically.
The technical problem that he overcame was that glass is very abrasive. "Conventional machines at that time were either not sophisticated enough to sort and separate to Karter's satisfaction or wore out too quickly. 'I don't know how many glass breakers we tried. Glass is a very hard material. We finally found a compromise solution: we designed machines so that the working parts could be quickly replaced when they wore out.'"
Karter explained his motivation this way, "At my age, it is easy enough to think that I will be dead before the environmental crunch comes down on mankind. I keep working because I keep thinking about my grandchildren."
Karter was buried in the Duck River Cemetery.
