Brazilian municipalities face several difficulties while carrying out the municipal selective waste collection (MSWC); at the same time, waste pickers organizations (WPOs) need to overcome many challenges to compete in the waste management market. In order to reach the requirements of the Brazilian National Solid Waste Policy (NSWP), it is necessary to know which factors interfere in the performance of MSWC programs and WPOs to understand the relationships between these factors. The objective of this paper was to evaluate the sustainability of MSWC programs and WPOs in the State of Espírito Santo, Brazil, and propose a new methodological strategy. For data collection, questionnaires were given to municipal civil workers from 24 municipalities and managers of 23 WPOs to calculate sustainability indicators and their correlations. Means and frequencies were calculated to analyze indicators in relation to sustainability; peer-to-peer correlation analyses were performed to the construct graphs that obtained correlation coefficients, which were applied to study the normality distribution. For each indicator, we provided necessary investments to practical solutions. As a result, a methodological proposal was presented to improve their actions, which was hierarchized by degrees of temporal urgency for their implementation. The design of the actions has great potential to improve and develop sustainability practices in WPOs and MSWC programs. Due to the low quality of primary data collected, we recommend the creation of the data control systems to continuously monitor.

废物收集组织和市政选择性废物收集:可持续性指标。

巴西市政当局在进行市政选择性废物收集(MSWC)时面临若干困难;同时,废物收集组织(WPO)需要克服许多挑战才能在废物管理市场中竞争。为了达到巴西国家固体废物政策(NSWP)的要求,有必要知道哪些因素会影响MSWC计划和WPO的绩效,以了解这些因素之间的关系。本文的目的是评估巴西圣埃斯皮里图州MSWC计划和WPO的可持续性,并提出一种新的方法论策略。为了收集数据,向24个城市的市政民工和23个WPO的管理人员发放了问卷,以计算可持续性指标及其相关性。计算平均值和频率以分析与可持续性有关的指标;对获得相关系数的构造图进行对等相关分析,将其用于研究正态分布。对于每个指标,我们为实际解决方案提供了必要的投资。结果,提出了一种改进他们行动的方法论建议,并按执行它们的时间紧迫程度对其进行了分层。这些行动的设计具有巨大的潜力,可以改善和发展WPO和MSWC计划中的可持续性实践。由于收集的原始数据质量低下,我们建议创建数据控制系统以进行连续监视。对获得相关系数的构造图进行对等相关分析,将其用于研究正态分布。对于每个指标,我们为实际解决方案提供了必要的投资。结果,提出了一种改进他们行动的方法论建议,并按执行它们的时间紧迫程度对其进行了分层。这些行动的设计具有巨大的潜力,可以改善和发展WPO和MSWC计划中的可持续性实践。由于收集的原始数据质量低下,我们建议创建数据控制系统以进行连续监视。对获得相关系数的构造图进行对等相关分析,将其用于研究正态分布。对于每个指标,我们为实际解决方案提供了必要的投资。结果,提出了一种改进他们行动的方法论建议,并按执行它们的时间紧迫程度对其进行了分层。这些行动的设计具有巨大的潜力,可以改善和发展WPO和MSWC计划中的可持续性实践。由于收集的原始数据质量低下,我们建议创建数据控制系统以进行连续监视。结果,提出了一种改进他们行动的方法论建议,并按执行它们的时间紧迫程度对其进行了分层。这些行动的设计具有巨大的潜力,可以改善和发展WPO和MSWC计划中的可持续性实践。由于收集的原始数据质量低下,我们建议创建数据控制系统以进行连续监视。结果,提出了一种改进他们行动的方法论建议,并按执行它们的时间紧迫程度对其进行了分层。这些行动的设计具有巨大的潜力,可以改善和发展WPO和MSWC计划中的可持续性实践。由于收集的原始数据质量低下,我们建议创建数据控制系统以进行连续监视。
