Abstract:
South Africa has plenty of abandoned mines and green rehabilitation options have been tested to try and resolve the problem. My study began with three bamboo species used on a wine effluent area and once the bamboo specie survived the climatic and contaminated conditions it became imperative to establish possible end applications. This paper is a continuation of the first phase of analysis performed on the same three bamboo species and now focuses on determining the elemental analysis of the bamboo species, control, and contaminated soil in which the bamboo species were planted on. Two bamboo species were selected for the combustion and co-combustion with coal based on their positive results from the initial analysis. The combustion tests were performed on the different sections (top, middle and bottom) of the bamboo specie. The elemental analysis results indicated high levels of elements such as Aluminum, Lead, Potassium and Phosphorus on all the contaminated (wine effluent) soil and lower concentrations of the same elements on the bamboo samples. The combustion tests illustrated high ignition, quick burnout temperature and high reactivity rate when combusted alone and that the Bambusa Balcooa had the best results overall. The coal had the worst combustion reactivity, slow ignition, slow burnout temperatures and it had the worst results from all the combined ratio samples tested. The best combination ratio for bamboo: coal was discovered to be the 70:30 ratio. Different material phases using the x-ray powder diffractogram were obtained from the crystalline material even though the samples had similar elemental composition.
