Innovative biochar production by co-carbonisation of plantain stalks with polyester fabric wastes
Agricultural and textile waste management presents significant environmental challenges globally. This study explores an innovative approach to biochar production through co-carbonization of plantain stalks with polyester fabric waste. Plantain stalks (90%) were combined with waste polyester fabric (10%) and processed using an auto-thermal carbonization reactor. The hybrid biochar demonstrated superior properties compared to plantain stalk-only biochar. The hybrid biochar achieved a 39.6% yield at 426.7 °C versus a 37.2% yield at 395.93 °C for the pristine biochar. Surface characterization revealed significant improvements: the hybrid biochar exhibited 29% greater surface area (492.172 m2/g), 9% higher pore volume, and 15% larger pore diameter compared to the pristine biochar. The surface of the hybrid biochar was smoother and had clumps of particles, and the analysis of its elements showed it had more potassium than the regular biochar. Functional group analysis confirmed retention of key functional groups. These findings demonstrate the potential for converting dual waste streams into enhanced biochar products, supporting circular economy principles and sustainable waste management. The improved properties suggest applications in agriculture, environmental remediation, and material science. This research addresses the pressing need for innovative waste management solutions while creating value-added products from agricultural and textile waste.
期刊介绍：
International Journal of Environmental Science and Technology (IJEST) is an international scholarly refereed research journal which aims to promote the theory and practice of environmental science and technology, innovation, engineering and management.
A broad outline of the journal''s scope includes: peer reviewed original research articles, case and technical reports, reviews and analyses papers, short communications and notes to the editor, in interdisciplinary information on the practice and status of research in environmental science and technology, both natural and man made.
The main aspects of research areas include, but are not exclusive to; environmental chemistry and biology, environments pollution control and abatement technology, transport and fate of pollutants in the environment, concentrations and dispersion of wastes in air, water, and soil, point and non-point sources pollution, heavy metals and organic compounds in the environment, atmospheric pollutants and trace gases, solid and hazardous waste management; soil biodegradation and bioremediation of contaminated sites; environmental impact assessment, industrial ecology, ecological and human risk assessment; improved energy management and auditing efficiency and environmental standards and criteria.
