Integrated electro-coagulation: A novel approach for the separation and valorization of lignin
This research aims to establish an integrated and sustainable electrocoagulation process for separating and valorizing the lignin from the black liquor after the kraft pulping process. Experiments have been conducted to study the performances of different electrodes, i.e., aluminum and iron. It has been observed that with iron electrodes, the lignin removal efficiency from black liquor was 91%, much higher than the conventional methods. Also, electro-coagulated lignin from the electrocoagulation of black liquor was used to directly synthesize Magnetic Mesoporous Activated Carbon (MMAC) through carbonization. In the future, a detailed feasibility analysis of the integrated electrocoagulation process in the pulp and paper industry will be conducted. The properties of the different electro-coagulated lignins will be thoroughly characterized by various techniques, and these lignins will be evaluated for higher-value applications.

Pulp and paper sludge valorization: A Comprehensive techno-economic and life cycle assessment for enhanced methane production
This research aims to establish a cost-effective and eco-friendly process for valorizing pulp and paper sludge (PPS) through anaerobic digestion (AD) for biogas production. It focuses on optimizing the process modeling using Techno-Economic Analysis (TEA) and Life Cycle Assessment (LCA) methods, with an emphasis on methane yield and efficiency. We have conducted a preliminary TEA for three scenarios of PPS anaerobic digestion: A) the base case, B) sludge AD with alkaline pretreatment using green liquor dregs (GLD), and C) co-digestion with food waste. It was found that scenario C) is the most economically viable option.

Engineering high-performance cellulose fiber and bioplastic composites with enhanced biodegradability tailored for packaging applications
This research focuses on developing sustainable packaging materials by incorporating cellulose fibers and a green plasticizer into a polylactic acid (PLA) matrix, aiming to produce a 100% biobased plastic for a greener future. So far, composites have been successfully prepared and tested, showing improved tensile and flexural strength compared to neat PLA. Ongoing work includes evaluating the biodegradability, thermophysical properties, and barrier performance of these materials to assess their suitability for real-world packaging applications. In addition, as a separate project, the production of lactic acid via bacterial fermentation—used as the main feedstock for PLA—has also been examined.

Spray dried biomaterials for pollutants separation from gas and liquid phase: Adsorption equilibrium, kinetics, and thermodynamics study
This research aims to produce hollow carbon spheres (HCSs) from kraft lignin and use this material to remove pollutants from both gas and liquid phases. We have synthesized HCSs by spray drying lignin-KOH solution. Raman spectroscopy test showed that the relative ratio of the intensity of the D (disordered carbon) band to the G (graphitized carbon) band increased with the rising carbonization temperature. This result was in agreement with the XRD and BET results, which also showed that the samples have more porous and disordered structures at higher temperatures. Continuous fixed-bed adsorption tests for removing methylene blue from wastewater were conducted using HCSs, and the breakthrough curves for three different initial concentrations of MB were achieved. The data points fit the Thomas model very well at all concentrations, indicating that continuous adsorption follows the Langmuir model and second-order kinetics; this agrees with the batch experiment results. Also, the highest adsorption capacity for continuous fixed-bed adsorption was 628 mg g-1.

Novel Pulping/Bleaching and Integrated Biorefining Technologies to Improve Efficiency and Reduce Carbon Footprint
This research focuses on enhancing process efficiency and environmental sustainability in the pulp and paper industries through an integrated approach. As part of our ongoing research, we have investigated the role of a novel additive (2,4-Xylenol) in kraft pulping using a state-of-the-art M/K laboratory batch digester and mill-environment (unscreened) wood chips and demonstrated that this novel additive significantly enhances delignification selectivity, recording a relative yield gain of 3.7% with only 0.5 wt.% additive dosage. This increased selectivity has potential industrial benefits in terms of additional pulp production, lower cooking and bleaching chemicals consumption, energy savings, and so on. Future initiatives will focus on cost-effective isolation and reuse of these phenolic additives from spent cooking liquor and on analyzing the structural features of the isolated lignins using advanced tools to gain insights into the reaction mechanism. As part of our ongoing research into lignin applications, we have developed a novel method for modifying lignin in black liquor from alkaline pulping through phenolation. We have synthesized phenolated lignins using conventional oil baths and microwave heating methods and characterized them using NMR (31P and 2D HSQC) and GPC Our preliminary results indicate that the phenolation of lignin in black liquor at a lower lignin to phenol ratio results in a more than threefold increase in H-unit content. Future applications of this modified lignin include its use as a recyclable vitrimer and as an asphalt bio binder. The outcomes of these technological advancements will be systematically evaluated through life cycle assessment (LCA) to delineate their environmental advantages relative to conventional practices.

Conversion of carbon dioxide in flue gas from the pulp and paper industry to ethylene via electrochemical and thermochemical methods
This project aims to develop efficient and sustainable methods for converting carbon dioxide (CO?) into valuable products using both electrochemical and thermochemical approaches. Our strategy involves a two-step process: in the first stage, CO? is converted to carbon monoxide (CO), which can then be used as an intermediate for the synthesis of higher-value products such as ethylene. In the thermochemical process, we achieved a CO? conversion rate of approximately 85% at temperatures up to 800?°C by treating biochar with potassium-based compounds to enhance its surface area and catalytic activity. In contrast, the electrochemical method demonstrated superior performance, with copper-based cathodes achieving over 90% efficiency in converting CO? to CO.

New Perspectives and Enhancement of Soybean Hulls as Functional Binders and Other Value-Added Applications
This research aims for a full biomass utilization of soybean hull (SBH) as an animal feed pellet binder using dilute acid treatment under agitation and elevated temperature for production. When incorporating the binder at a 2% addition into aquatic floating feed pellets, the water recovery of pellets increased to over 75% compared to around 64% for commercial aquatic feed binders (i.e. wheat gluten and corn starch). This increase in water stability can be attributed to better binding between the soybean hull binder and the other constituents present within the feed pellet matrix. While the previous work has shown that the SBH binder outperforms other commercial binders in terms of water stability, determining the mechanism of binding to further optimize the production is the main aim for future work on this project. We plan to do this through a thorough chemical analysis and developing a novel binder testing method to allow for quick and easy “binding capability” comparisons between binder batches at different operating conditions.

Microwave Assisted Biodiesel Production from Crude Tall Oil (CTO)
This research investigates the kinetics of biodiesel production from crude tall oil (CTO) via microwave-assisted transesterification, using a microwave reactor coupled with an in-situ Raman spectrophotometer. CTO, a low-cost, lignocellulosic by-product of the pulp and paper industry, was employed as a sustainable non-edible feedstock. By integrating real-time Raman monitoring into the microwave reactor system, the study offers a unique platform to track the evolution of key functional groups (e.g., ester C=O at ~1740 cm?¹) and quantify reaction progress without interrupting the process. The time-resolved Raman spectra reveal kinetic trends, catalyst activity profiles, and ester formation dynamics. This work advances the understanding of fast, efficient, and green biodiesel synthesis while demonstrating the value of spectroscopic integration for real-time reaction control in biofuel production.
