La biotecnología incluye la elaboración de diversos productos útiles para el hombre mediante el procesamiento de biomateriales, para la obtención de nuevas medicinas, el mejoramiento de las prácticas de cultivo y el tratamiento de los residuos líquidos y sólidos.

En ello, la ingeniería de procesos debe apuntar al uso de agentes biológicos como las células, enzimas o anticuerpos. Es de suma importancia para el futuro de la humanidad contar con profesionales que dominen estos conceptos, ya que tanto la elaboración de muchos productos alimenticios (quesos, cerveza, o yogurt) como el tratamiento biológico de vertidos (obtener agua limpia a partir de agua sucia) dependen de esta disciplina.
