| Abstract |
Biochar has been found to be suitable for a wide array of applications. However, the repurpose of spent biochar has been far less explored. In this study, we utilized biochar as a pH treatment for wastewater effluent obtained from the pineapple fibre retting process and then used the spent biochar as a growth substrate media in place of commercially and non-reusable substrates, such as peat and rockwool. Biochar produced from wheat straw was used to treat the effluent which was then characterized for macro and micronutrient content. Treatment of effluent with biochar increased the micronutrients in the effluent, such as the iron content by 10-fold and the manganese content by 5-fold. The biochar treated wastewater effluent from the pineapple fibre retting was used as hydroponic medium to grow basil and arugula. The spent biochar was subsequently used as a growth substrate medium as a replacement for rockwool and peat. Initial tests showed successful germination for basil and arugula. |
