Dissolve waste polystyrene (foam cups/plates) in biodiesel for more power

Kong and colleagues dissolved polystyrene – a polymer used to make disposable foam plates and cups – into biodiesel at concentrations ranging from 2 to 20% polystyrene by weight. "A polystyrene cup will dissolve almost instantly in biodiesel, like a snowflake in water," Kong says, although the plastic doesn't break down as well in petroleum-based diesel and other liquid fuels.

Tests of the mixed fuel in a tractor engine used for electricity generation showed that as polystyrene concentrations increased to 5%, power output increased at roughly the same rate. However, there was a drop off in output for plastic concentrations above 5%.

I remember dissolving styrofoam packing peanuts in gasoline with a friend in high school, it dissolved readily and made a goop that was effectively napalm.
