In South Africa, waste pickers play a significant role in the management of waste at landfill sites. Waste picking is an income-generating venture for most people with low-income base. The activity of sorting waste at landfill sites is, however, associated with occupational health risks to waste pickers which this study has examined. The study adopted a cross-sectional survey with a convenience sampling method which was conducted among 114 waste pickers in three landfill sites in Limpopo Province of South Africa. A validated questionnaire was used in eliciting responses from the participants. The statistical technique employed includes the ANOVA, simple, and multiple regression. The results indicated that, in the last one year, waste pickers exposed to landfill sites were 1.7 times more likely to develop a common health disorder (AOR: 1.733; 95% CI: 1.069, 2.755; P value: 0.041). There was statistical significance between the number of days worked at the landfill and the health conditions of the waste pickers (P ≤ 0.001). The cofounders were adjusted for age and years worked, and the result revealed that days worked by the waste pickers' increased their chances of occupational health risks by 1.4 times. It is unlikely that waste pickers will have a risk-free environment, but supportive policies such as provision of adequate personal protective equipment and more awareness programmes on the health risks related to such enterprises will aid in abating the associated risks.

This article focuses on the development of a conceptual framework guiding the adoption of biogas technology in selected rural areas of the Limpopo province. The theoretical framing of the study emanated from the critical evaluation of models and work that privileged the technical design and optimisation of a biogas system over the adoption of the technology at the household level. Based on the empirical evidence, and using logistic regression analysis, the study highlighted that determinants of biogas technology adoption in communities are complex, context-dependent and spatially varied. Hence, the policy of biogas adoption should be tailored based on the principle of fit-for-purpose, instead of using existing unimodal approaches for all settings. Based on the findings, the study developed a robust conceptual framework that harnesses the relationships between the influencing variables that can enhance the adoption of biogas technology.
