In work illustrated, the mixed food reject was carbonized and further activated with zinc chloride for biodiesel washwater treatment experiments. Biodiesel washwater is one of the significant side streams generated during biodiesel production from waste cooking oil. The food waste activated carbon (FWAC) and commercial activated carbon (CAC) were analyzed for structural and surface morphology using X-ray diffraction (XRD), Filed emission scanning microscopy (FE-SEM) and IR-Raman spectroscopy. The adsorption experiments were performed at 10 to 50 minutes with an adsorbent dosage of 0.1 to 0.5 in 100 mL of biodiesel wash water. pH, Turbidity and Total dissolved solid of biodiesel plant effluent before and after adsorption experiments were determined. Food waste-activated carbon used for the study reduced the effluent pH from 11.5 to 7, Turbidity from 435 NTU to 1 NTU and TDS from 1140 mg/L to 145 mg/L. The feasibility of NaOH recovery from biodiesel wash water was also studied.

In recent years, there has been a steady increase in the intensity and frequency of wildfires worldwide mainly due to the escalating climate crisis and land-use change. Wildfires result in a decline in air quality and cause damage to property, crops, resources, wildlife, and human lives. Since models predict that the number of wildfires will rise by 50% by 2100 the reduction of the wildfire risk is more crucial than ever. We herewith attempt to develop a simple model for nowcasting such catastrophic events that may be useful for preparing authorities and policymakers. As an example, the case of the USA is presented by analyzing the count of wildfires and acres burned there over the past four decades to forecast such catastrophic events over the next ten years. The approach employed in this research can serve as an additional resource in the field of environment and fire ecology, aiding in identifying fire-adapted ecosystems and fire patterns.
