by-products
Incidental manufacturing results
By-products are secondary substances produced during the manufacture or processing of something else.
Sawdust is a by-product of lumber milling; whey is a by-product of cheese making.
The term extends to any incidental result or consequence: Cynicism is a by-product of disappointment.
Also spelled *byproducts*.
