Solid waste management in many cities of developing countries is not environmentally sustainable. People traditionally dispose of their solid waste in unsuitable urban areas like sidewalks and satellite dumpsites. This situation nowadays has become a serious public health problem in big Latin American conurbations. Among these densely-populated urban spaces, the Colombia's capital and main city stands out as a special case. In this study, we aim to identify the factors that shape the attitudes towards source-separated recycling among households in Bogotá. Using data from the Colombian Department of Statistics and Bogotá's multi-purpose survey, we estimated a multivariate Probit model. In general, our results show that the higher the household's socioeconomic class, the greater its effort for separating solid wastes. Likewise, our findings also allowed us to characterize household profiles regarding solid waste separation and considering each socioeconomic class. Among these profiles, we found that at lower socioeconomic classes, the attitudes towards solid waste separation are influenced by the use of Internet, the membership to an environmentalist organization, the level of education of the head of household and the homeownership. Hence, increasing the education levels within the poorest segment of the population, promoting affordable housing policies and facilitating Internet access for the vulnerable population could reinforce households' attitudes towards a greater source-separated recycling effort.
许多发展中国家城市的固体废物管理并不具有环境可持续性。人们传统上将固体废物丢弃在不合适的城市区域，如人行道和卫星垃圾场。这种情况如今已成为拉丁美洲大型城市群的一个严重公共卫生问题。在这些人口密集的城市空间中，哥伦比亚的首都和主要城市尤为突出。在这项研究中，我们旨在确定塑造波哥大家庭对源头分类回收态度的因素。我们使用来自哥伦比亚统计局和波哥大多用途调查的数据，估计了一个多元 Probit 模型。总的来说，我们的结果表明，家庭的社会经济阶层越高，对固体废物进行分类的努力就越大。同样，我们的研究结果还使我们能够根据固体废物分类并考虑每个社会经济阶层来描述家庭概况。在这些概况中，我们发现，在较低的社会经济阶层，对固体废物分类的态度受到互联网使用、环保组织成员资格、家庭主妇的教育水平和住房拥有情况的影响。因此，提高贫困人口的教育水平，推行负担得起的住房政策，并为弱势群体提供互联网接入，都可以增强家庭对更大力度源头分类回收的态度。
