WHEN IT GETS US THERE
By-products are used in all types of mechanical items to
get us where we're going. Chemical manufacturers use numerous fatty acids
from inedible beef fats and proteins, for all sorts of lubricants and
fluids. Antifreeze contains glycerol derived from fatty acids to keep your
car running cool. Tires have stearic acid which makes the rubber hold its
shape under continuous surface friction. Glue from colloidal proteins has
been used in automobile bodies. Even the asphalt on our roadways has a
binding agent from fat.
