National bioeconomy strategies aim for a comprehensive transition from a fossil-based to a biomass-based economy. One common feature of the strategies is the optimistic reliance on technology as main tool in order to overcome the socio-ecological crisis. From the critical perspectives of political ecology and the political economy of research and innovation, technologies and technological innovations are not neutral solutions to the problem; they are generally socially embedded. Against this backdrop, we contextualise the technological innovations that support a more climate-friendly production of ethanol on a sugarcane basis, building on a field research in the more recently developed cultivation areas in Mato Grosso do Sul, Brazil. In doing so, we explore the co-production of the green framing of the sector in combination with technologies for a more climate-friendly agriculture and the political economy of land. Our investigation shows that the bioeconomy in the sugar-ethanol sector perpetuates the socio-ecological problems associated with the agricultural sector. These socio-ecological problems range from the increasing concentration of landownership to the negative impact of agrotoxins.
