It provides a platform not only for basic research but also for industrial interests.Man charged after Fayetteville hostage situationįAYETTEVILLE, N.C. It emphasizes the application of waste disposal and sustainable energy technology to environmental and earth issues. The invention of instrumentation and new-methods on waste characterization and collection are also included. It broadly encompassed various traditional waste disposal and new sustainable energy sources related topics. Waste Disposal & Sustainable Energy (WDSE) publishes high-quality papers that advance waste disposal and sustainable energy. We also acknowledge the financial and in-kind support of the project participants.Ībout Waste Disposal & Sustainable Energy Scarlett Allende acknowledges the financial support of the Cooperative Research Centre for Developing Northern Australia and the support of its investment partners: the Western Australian, Northern Territory and Queensland Governments. This study represents an important step towards a circular economy, and open up new opportunities for waste utilization and resource recovery, bringing us closer to a more sustainable and efficient future. The material's unique properties, such as its high surface area, micropore structure, and electrocatalytic activity, make it well-suited for detecting and analyzing different analytes of interest in these fields. The researchers envision future applications of ZnCl2-activated biochar in environmental monitoring, food quality control, and medical diagnostics. The conversion of agricultural waste into high-value biochar through microwave-assisted pyrolysis, followed by chemical activation, provides a versatile material for various applications, particularly in electrochemical sensing. This innovative approach to utilizing pineapple peel waste offers a sustainable solution for resource recovery and waste reduction. The sensor's performance was comparable to or better than existing electrochemical sensors reported in the literature. ![]() It exhibited high selectivity, reproducibility (RSD=2.4%), and stability (RSD=2.6%) over ten days of storage. Furthermore, the sensor demonstrated excellent sensitivity, with a limit of detection of 0.97 µmol L−1 for nitrite. The electrochemical impedance spectroscopy revealed a 61% decrease in charge transfer resistance compared to the bare GCE. The results showed a significant reduction in charge transfer resistance, indicating improved electron transfer kinetics. The electrochemical properties of the ZnCl2-activated biochar-modified GCE were characterized using various techniques. The researchers applied the activated biochar to a glassy carbon electrode (GCE) through drop casting. The activated biochar exhibited a high surface area, micropore structure, and oxygen-containing functional groups, which are crucial for electrochemical sensing applications. ZnCl2 is a chemical agent that enhances its electrocatalytic activity. The study highlights the potential of transforming agricultural waste into valuable resources for environmental and economic sustainability.
