Waste recycling, in particular source separation contribute significantly to the extension of landfill life and the evolution of green communities. Factors that affect participation in source waste separation amongst Metropolitans Johannesburg residents was investigated by social survey using field questionnaire data to assess socio-demographic factors and was analysed by statistical tools and behavioural constructs i.e. attitudes, subjective norms, perceived behavioural control, intentions, and situational factors. The results revealed that for graduates, source separation was driven by social responsibilities and family size while council awareness campaign, financial incentives and provision of recycling facilities are the driving force for source separation amongst respondents with matric and lower formal education. Family size and level of education are correlated to attitude with low correlations. The weak correlation was due to the perception of quality of services provided by the council. Incentives are moderators of intention of source separation but distances to buyback centre have to be carefully selected in order not to be a deterrent. Waste management agencies should accommodate the level of formal education and different family size in the formulation of source separation program.
废物回收，特别是源头分类，对延长垃圾填埋场的使用寿命和建设绿色社区有重要贡献。本研究通过问卷调查和现场数据收集，采用社会调查的方法，利用统计工具和行为结构（即态度、主观规范、感知行为控制、意图和情境因素）来研究影响约翰内斯堡大都市居民参与源头废物分类的因素。结果表明，对于毕业生来说，源头分类是由社会责任和家庭规模驱动的，而议会意识运动、经济激励和回收设施的提供是对具有 Matric 和较低正规教育程度的受访者进行源头分类的驱动力。家庭规模和教育水平与态度相关，相关性较低。这种弱相关性是由于对议会提供服务质量的看法。激励是源头分类意图的调节因素，但必须仔细选择回购中心的距离，以免成为障碍。废物管理机构应在制定源头分类计划时考虑到正规教育水平和不同的家庭规模。
