Dr Debajyoti Kundu, Assistant Professor, Department of Environmental Science and Engineering, has conducted an impactful study on developing polyhydroxyalkanoates (PHA), an eco-friendly solution that can help reduce plastic waste and make food packaging more sustainable. His recent paper “Advancements in microbial production of polyhydroxyalkanoates (PHA) from wastes for sustainable active food packaging: An eclectic review”, published in the Q1 journal Biocatalysis and Agricultural Biotechnology, Dr Debajyoti investigates how microorganisms can convert waste into a special type of plastic called PHA, which can be used for food packaging.

Unlike regular plastics, PHA is biodegradable and safe for both the environment and human health. The study reviews recent innovations in making PHA stronger and more effective for packaging, including its ability to prevent food spoilage and improve food safety.

Abstract

This study explores advancements in microbial production of polyhydroxyalkanoates (PHA) from waste resources for sustainable active food packaging. It highlights the eco-friendly nature of PHAs as bioplastics and their potential to replace synthetic plastics in food packaging. The paper discusses recent technological improvements in PHA production and formulations, focusing on enhancing material properties to make PHA a viable alternative. It also examines trends in active packaging, including antimicrobial, antioxidant properties, and spoilage indicators, which can significantly improve food safety and quality.

Practical Implementation/ Social Implications of the Research

The practical implementation of this research involves using PHA-based materials for food packaging to replace conventional plastics. This can lead to reduced environmental pollution due to PHA’s biodegradability and lower reliance on fossil fuels. Social implications include improved food safety through active packaging features like antimicrobial and antioxidant properties, potentially reducing foodborne illnesses and extending shelf life. Additionally, using waste to produce PHA promotes waste recycling and resource efficiency.

Collaborations

This research is a collaborative effort among various prestigious institutions including St. Joseph’s University, SRM Institute of Science and Technology, Gurudas College, and SRM University-AP.

Moving forward, Dr Debajyoti will continue to work on improving the production processes and formulations of PHA to enhance its mechanical properties and cost-effectiveness. Additionally, he will explore new waste sources for PHA production and develop advanced active packaging technologies, such as smart packaging with sensors for real-time monitoring of food quality. Collaborations with industry partners to scale up production and test real-world applications of PHA-based packaging are another key focus.

SRM University-AP extends a warm welcome to its newest cohort of students as it kicks off the much-anticipated “UDAAN 2024” orientation programme. This 10-day event, running from August 12 to August 23, is meticulously crafted to seamlessly integrate more than 3000 freshers from more than 20 states of India into the vibrant campus life and academic environment.

The event began with the traditional lighting of the lamp and an invocation ceremony, setting a tone of reverence and inspiration. During the inaugural session, students were given an overview of the university’s various directorates, schools, and the academic ecosystem, providing them with essential knowledge about their new environment. Deans and directors from all departments were present, underscoring the importance of this milestone in the student’s academic journey.

Pro-Chancellor, SRM University-AP Dr P Sathyanarayanan, extended his warmest wishes to the students, stating “At SRM AP, we are dedicated to shaping the next generation of leaders, innovators, and change-makers. With UDAAN 2024, we are excited to empower our students as they embark on this transformative educational journey. It is our hope that this experience inspires each of you to achieve excellence and make a meaningful impact on the world. Welcome to a vibrant community where your future truly begins.”

Vice Chancellor, SRM University-AP, Prof. Manoj K Arora, addressed the new students, encouraging them to embrace self-reliance and to make the most of every opportunity during their time at the university. He motivated the students and said that they have an opportunity to learn new things, acquire new knowledge, grow new competencies, develop new skills and enhance their personal attributes in profound ways that will shape their character for the rest of their lives. Prof. Arora further added that the students have an opportunity to weave new friendships that will impact their lives in incredible ways and that education is not only about acquiring knowledge and skills, but it also prepares us for life.

The programme was honoured by the presence of Indian Ambassador Deepak Vohra ji, Special Advisor to Prime Minister in Africa and Ladakh, who was the chief guest for the event. His address to the students motivated them on how to attain great heights in their careers even in adverse situations through relentless goal setting, hard work, dedication and determination. He further told the students that if we are divided, we can go fast, but if we are united, we can go far. Deepak Vohra concluded his speech with this line, “The future of India is the future of the world. The whole world trusts India because we are intrinsically good people. You are the hope for the future of a safe and secure world.”

Throughout this 10-day programme, students will participate in a series of sessions designed to familiarise them with the university’s offerings. These include introductions to the academic departments, faculty, and administrative staff, as well as insights into the various clubs and associations that contribute to a holistic educational experience at SRM University-AP.

Dr Debajyoti Kundu, Assistant Professor in the Department of Environmental Science and Engineering, has published a research paper titled “Synthesis, delineation and technological advancements of algae biochar for sustainable remediation of the emerging pollutants from wastewater – A Review” in the esteemed Q1 journal “Environmental Research”, which has an impact factor of 8.3.

Dr Debajyoti’s research focuses on using algae biochar, which is particularly effective at cleaning polluted water. The study reviews how this biochar is made and improved and how it can effectively remove harmful substances from wastewater. This process is sustainable and environmentally friendly, offering a promising solution to water pollution.

Abstract

The study examines the synthesis, technological advancements, and applications of algae biochar for the sustainable remediation of emerging pollutants from wastewater. It highlights the unique properties of algae biochar, including its high surface area, pore volume, and adsorption capacity, which make it an effective medium for removing inorganic and organic contaminants from wastewater. The paper discusses various methods for producing algae biochar, such as pyrolysis, gasification, and torrefaction, and explores chemical and structural modifications to enhance its pollutant removal efficiency.

Practical Implementation /Social Implications of the Research

The practical implementation of this research involves using algae-derived biochar in wastewater treatment plants to remove harmful pollutants. This can lead to cleaner water, reduced environmental pollution, and improved public health. The process is also sustainable and cost-effective, contributing to environmental conservation and resource efficiency.
