摘要

循环经济(CE)已被采用作为线性经济模式的替代方案,因为它改变了产品的设计和消费方式。农业食品链是确保向符合环保原则的可持续发展模式过渡的关键。本研究试图在厄瓜多尔的香蕉生产链上实施循环经济的概念,通过对链上主要过程的详尽诊断的前瞻性设计。该研究从2020年到2022年进行。研究清单包括91个项目,分为9个维度:材料来源或供应、设计、制造、经济圈、分销和销售、消费和使用、4R、再制造和可持续性。评估了中等循环经济水平(CEL)(2.69分)。还应用了两种机器学习技术(mlt),支持向量机(SVM)(具有三种核:径向,线性和多项式)和神经网络(NN)。与研究案例应用的Spearman相关系数均大于0.90。最可靠的是SVM回归线性核函数,其系数接近于1。最后,提出了各种增值方案,以利用香蕉生产系统中产生的大量废物。提议的选项包括增值过程,包括有机肥料、生物燃料、废水处理材料以及生物塑料和纳米颗粒的生产,这些都可以使用CE方法实施。

Prospective of the circular economy in a banana agri-food chain
The circular economy (CE) has been adopted as an alternative to the linear economic model, since it transforms the way products are designed and consumed. Agri-food chains are key to ensuring the transition to a sustainable development model in line with the principles of CE. This study sought to implement the concepts of circular economy at the Ecuador's banana production chain, through the design of prospective from the exhaustive diagnosis of the main processes of the chain. The research was conducted from 2020 to 2022. The studied checklist included 91 items grouped into nine dimensions: source or supply of materials, design, manufacturing, economic circle, distribution and sales, consumption and use, 4R, re-manufacturing, and sustainability. A medium circular economy level (CEL) was evaluated (2.69 points out of 5). Two machine learning techniques (MLTs) were also applied support vector machine (SVM), (with three types of kernel: radial, linear and polynomial) and a neural network (NN). In relation to the Spearman correlation coefficients of the application of the techniques to the study cases, they were higher than 0.90. The most reliable was the SVM Regression-Linear Kernel, which had a coefficient close to 1. Finally, various value-adding options are proposed in order to take advantage of the large amount of waste generated in the banana production system. The proposed options include value-augmentation processes, ranging from organic fertilizers, biofuels, materials for wastewater treatment, and the production of bioplastics and nanoparticles, which can be implemented using the CE approach.
