Tall Oil: Production, Applications, Global Market, andFuture Prospects- A Review
Abstract: The global energy demand is experiencing rapid growth due to overpopulation and massive industrialization worldwide. The stringent environmental regulations to minimize fossil fuel reliance have led to a global need to develop renewable and sustainable fuel sources. Hence, industries are increasingly looking towards non-edible oils as natural resources for biofuels, and one such promising feedstock is tall oil, a valuable by-product of the pulping industry obtained through the Kraft process. …

Biostimulation of Petroleum Hydrocarbon ContaminatedSoils Using Bryophylum Pinnatum Extracts
Abstract: This study investigates the remediation potential of Bryophylum pinnatum extracts (water and ethanol-based) for degrading total petroleum hydrocarbons (TPH) in loamy and clay soils. Crude oil contaminants used in the study exhibited a pH of 6.76, density of 0.878 g/mL at 15 °C, kinematic viscosity of 147.4 mm²/s at 40 °C, and a flash point of 193.2 °C. The baseline TPH concentration in the soils was 48,291.14 ppm. Soils were …

A Study on the Future of Industrial WastewaterTreatment Plant: Trends and Innovations
Abstract: Industrial wastewater treatment plants (IWWTPs) stand at the critical intersection of economic productivity and environmental sustainability. Unlike municipal sources, industrial effluent is characterized by extreme heterogeneity, containing highly variable concentrations of toxic heavy metals, recalcitrant organic compounds, suspended solids, and emerging contaminants. This complexity necessitates bespoke, multistage treatment trains, often combining physical, chemical, and advanced biological methods (e.g., membrane bioreactors, electrochemical oxidation, and anaerobic digestion). This analysis examines the contemporary …

Evaluation of Michaelis-Menten Constants of TPH Degradation on Clay Soil
Abstract: The degradation of Total Petroleum Hydrocarbons (TPH) in petroleum-contaminated clay soil remains a major environmental concern, particularly in regions with limited remediation options. This study investigates the enzymatic kinetics of TPH biodegradation using Michaelis-Menten modeling in the presence of Bryophyllum pinnatum leaf extracts as biostimulants. Fourteen bioreactors containing 2000g of contaminated clay soil were prepared with 100ml of crude oil and treated with varying doses (100ml, 200ml, and 300ml) of …
