The atmosphere was palpable as distinguished professors from the Faculty of Physical Science and other esteemed faculties of Nnamdi Azikiwe University, Awka converged to witness the highly anticipated 110th Inaugural Lecture. The intellectual giant, Prof. Theresa Uzoma Onuegbu, a renowned scholar of impeccable repute, was poised to take center stage, delivering a lecture that would undoubtedly leave the audience in awe.
Prof. Onuegbu’s lecture, “Averting Deforestation Through Deployment of Agricultural Wastes As Sources of Energy for Domestic and Industrial Uses: Perspectives of the Fire Chemistry,” highlighted the severe environmental consequences of deforestation driven by human activities. She emphasized the need for alternative energy solutions, citing the potential of agricultural waste briquettes to reduce deforestation, promote sustainability, and mitigate climate change.
The Impact of Deforestation and Wood-Based Fuels:
Prof. Theresa explained that deforestation which is driven by human activities like farming, urban development, logging, and mining, has severe environmental consequences. The high cost of cooking gas, kerosene, and electricity exacerbates the problem, leading to increased reliance on wood-based fuels. These fuels contribute to deforestation, biodiversity loss, and increased carbon emissions.
Need for Alternative Energy Solutions:
She opined that firewood use is a major driver of deforestation, especially in developing countries. However, unsustainable harvesting practices lead to forest degradation, loss of biodiversity, and increased carbon emissions. Agricultural waste offers a promising renewable energy alternative. By harnessing this waste, we can generate energy while protecting forests and promoting sustainability.
Benefits of Agricultural Waste Briquettes:
The erudite Prof of Polymer and Fire Chemistry, maintained that agricultural waste briquettes provide a sustainable energy solution, reducing waste disposal issues and promoting a cleaner environment. These offer a consistent and reliable source of energy, making them an energy-efficient option. Briquettes can be used domestically for cooking, heating, and electricity generation, and can power machinery and processes.
Types of Briquettes and Their Benefits:
Coal Briquettes: Efficient and convenient alternative to traditional coal.
Charcoal Briquettes: Long-lasting, high-heat, and virtually smokeless fuel.
Biomass Briquettes: Renewable energy source, carbon neutral, and low sulphur content.
Wood Briquettes: Low ash and sulphur content, efficient energy production.
She suggested that by transitioning to agricultural waste briquettes, we can reduce deforestation, promote sustainability, and mitigate climate change.
Special Remarks from the Acting Vice Chancellor:
The Acting Vice Chancellor, Prof. Carol Arinze-Umobi, represented by Prof. Ezimma Nnabuife, commended Prof. Theresa Uzoma Onuegbu for her courage and invaluable contributions to the growth and development of the institution. This gesture underscored the esteem in which Prof. Onuegbu is held by her peers and the university community.
