El biodiésel es ecológico y económico.
Explicación:
El biodiésel es un combustible que se produce a partir de aceite vegetal, es ecológico y económico porque no produce gases de efecto invernadero como dióxido de carbono y monóxido de carbono, etc., por lo que produce menos contaminación y también es económico debido a su alta eficiencia y está hecho de aceite de cocina que no lo es. costoso. Aproximadamente el 80% del biodiésel se elabora a partir de aceite vegetal y el 20% restante a partir de grasas animales.
