Uso de aguas residuales urbanas en el riego de colza (Brassica napus L.) con destino a biocombustible

Abstract

El aceite de colza es comestible pero también puede utilizarse en la producción de biodiesel. Cuando el destino es el energético, el cultivo puede regarse con aguas residuales urbanas o cloacales. La mayor proporción del uso de éstas en el mundo ocurre en regiones áridas donde otras fuentes de agua son escasas, situación que se plantea en los oasis irrigados de Mendoza. En este trabajo se comparó el rendimiento de un cultivar invernal de colza regado con agua cloacal (AC) y agua subterránea (AS), y su potencial para producir biodiesel. La experiencia se llevó a cabo en una planta de tratamiento de agua cloacal de Obras Sanitarias en el departamento Tunuyán (33° 32’ 89’’ S; 69° 00’ 80’’ O; 859 m snm). El rendimiento de semilla de AC fue significativamente mayor que el de AS (7690 y 3886 kg/ha, respectivamente). La cantidad de biodiesel factible de producir por cada hectárea de cultivo asciende a 2800 kg en el tratamiento AC y a 1400 kg en AS. El uso de aguas residuales urbanas genera un nicho interesante para la producción de biocombustibles, utilizando un recurso hídrico con limitaciones para producir alimentos.

Edible rape oil can be used as raw material to produce biodiesel. In this case, wastewater can be used for irrigation. In recent years wastewater use has gained importance in water-scarce regions. In this work yield and potential to produce biodiesel of a winter rape cultivar under two irrigation treatments (urban waste water (UWW) and ground water (GW)) were compared. The trial was conducted in the Urban Waste Water Treatment Plant of Obras Sanitarias Mendoza in Tunuyán (33° 32’ 89’’ S; 69° 00’ 80’’ W; 859 m osl). Seed yield was higher in UWW than in GW treatment (7690 and 3886 kg/ha respectively). Biodiesel potential production was 2800 kg/ha in UWW and 1400 kg/ha in GW treatment. Biodiesel production from urban waste water irrigation rape oil is an interesting niche to produce biofuels.
