Abstract

Brazil plays a prominent role in the global production of sugarcane and contributes to the renewable energy sector by producing ethanol. However, few studies have explored the adoption of the circular economy in the sugarcane ethanol sector. This article is aimed at analyzing and prioritizing barriers to the adoption of the circular economy in leading Brazilian sugarcane ethanol companies. For this, the analytical hierarchy process method and case studies methods were used. The main barriers identified were economic and financial, mainly due to dependence on high investments in production process technologies and the resulting uncertainties about returns. Another barrier was the lack of Brazilian legislation concerning the circular economy. We discuss the implications of our findings and present mechanisms for overcoming barriers and the role in supporting circular economy adoption in emerging economies.

巴西甘蔗乙醇行业采用循环经济的障碍

摘要

巴西在全球甘蔗生产中发挥着重要作用，并通过生产乙醇为可再生能源部门做出贡献。然而，很少有研究探讨在甘蔗乙醇行业采用循环经济。本文旨在分析和优先考虑巴西领先的甘蔗乙醇公司采用循环经济的障碍。为此，使用了层次分析法和案例研究方法。确定的主要障碍是经济和金融，主要是由于对生产工艺技术的高投资的依赖以及由此产生的回报的不确定性。另一个障碍是巴西缺乏关于循环经济的立法。
