"Dump all the cornflakes and bread and things on the ground, and we'll do biur chametz." (Glinert)

"This process, known as bi'ur chametz, begins by searching one’s home for chametz. Indeed, the blessing recited on bedikat chametz is not 'Al bedikat chametz,' but rather, 'Al bi'ur chametz.'" (source)

"The Mishna in Pesachim 2:1 records a dispute as to how Biur Chametz is to be done. Rabbi Yehuda, comparing the destruction of Chametz to the destruction of invalid Korbanot, rules that Chametz must be destroyed by burning. The Chachamim there argue and rule that any form of destruction (tossing into the sea, or crumbling it into the wind) is acceptable." (source)
