For access to the full text item, please consult the publisher's website.The suitability of different technology solutions for the beneficiation of biowaste is dependent on the physical and chemical properties of the specific waste stream. This research was undertaken as part of the EU FP7 funded Biowaste4SP project, which entailed beneficiation of biowaste via generation of biogas and production of compost – thus benefitting communities in developing countries in terms of avoidance of landfilling and generation of high value materials from biowaste. A study was conducted to identify and characterise the various solid biowaste streams available in South Africa with the ultimate aim of converting the waste into valuable products via waste-to-energy technologies to avoid their disposal by landfilling. Samples were collected from within the KwaZulu-Natal, Gauteng and Limpopo provinces. Representative samples for the identified streams were collected for analysis. The analytical tests performed for the characterisation of the solid biowaste residues included proximate and ultimate analysis, moisture content determination, ash content analysis, and strong acid hydrolysis for determination of total carbohydrates and acid insoluble material. Twelve biowaste types were identified. Sawdust had the highest volatile solids (VS) content (93%) whereas soybean waste and water hyacinth had the lowest VS content (63%). Elemental analysis results revealed that sugar cane bagasse, vegetable waste and banana (whole fruit) were highly carbonaceous (C > 40%) and furthermore, that sugar cane bagasse had the highest carbon : nitrogen (C : N) ratio (246.6:1). The results indicated that banana biowaste is suitable for conversion into biogas.enBioresiduesBiowasteVolatile solidsWaste-to-energyBook ChapterTawona, N., Sithole, B. B., & Parkin, J. (2018).
