Food waste is becoming an important issue in light of population growth and global food security concerns. However, data on food wastage are limited, especially for developing countries. Global estimates suggest that households in developed countries waste more food than those in developing countries, but these estimates are based on assumptions that have not been tested. We therefore set out to present primary data relating to household food waste disposal for South Africa within the sub-Saharan African context. As the Gauteng Province contributes about 45% of the total municipal waste generated in South Africa, the case study area covers two of the large urban metropolitan municipalities in Gauteng, namely Ekurhuleni and Johannesburg, with a combined population of 8.33 million, representing nearly 15% of the South African population. Municipal solid waste characterisation studies using bulk sampling with randomised grab sub-sampling were undertaken over a 6-week period during summer in 2014 (Johannesburg) and 2016 (Ekurhuleni), covering a representative sample of the municipal waste collection routes from households in each of the two surveyed municipalities. The food waste component of the household waste (excluding garden waste) was 3% in Ekurhuleni and 7% in Johannesburg. The results indicate that an average of 0.48 kg (Ekurhuleni) and 0.69 kg (Johannesburg) of food waste (including inedible parts) is disposed of into the municipal bin per household per week in the two municipalities, respectively. This translates into per capita food waste disposal of 8 kg and 12 kg per annum, respectively, in South Africa as compared to the estimated 6–11 kg per annum in sub-Saharan Africa and South and Southeast Asia.

In South Africa, until recently, veterinary waste has not been included in definitions of health care waste, and so has been neglected as a contributor to the hazardous waste stream. Despite the application of, for example, the "Polluter Pays" principle in South African environmental legislation, to generators of waste, which would include veterinarians, there appears to be little awareness of and even less enforcement of the legislation in this regard. This paper reports on a 2001-2003 survey of management practices of the five waste contractors servicing just over half of the veterinarians in Durban, South Africa's second largest city. Some of their activities, when evaluated in terms of the legislation, guidelines and policies relating to waste handling and disposal, were found to be non-compliant. Since any discussion on waste management should take cognisance of waste from generation to final disposal, the responsibility of veterinarians as waste generators is also discussed in the light of the recent developments in health care waste management in South Africa. This study presents a review of past and current policies, legislation and guidelines that have application to veterinary waste. This is the first study to address veterinary waste disposal in any South African city.
