by-product
Secondary manufacturing output
A by-product is something produced incidentally in making or doing something else.
Manufacturing processes yield by-products—molasses is a by-product of sugar refining.
The term extends to any secondary result: Unemployment is a by-product of automation.
By-products may be valuable, worthless, or harmful depending on context.
