In a groundbreaking revelation poised to revolutionize sustainability practices, scientists from King Mongkut’s University of Technology Thonburi (KMUTT) have uncovered a transformative process that turns food leftovers into a fuel comparable to low-grade coal.
Led by Dr. Trairat Muangthong-on, a team of researchers at KMUTT has pioneered a method for converting various food waste materials into biochar, a charcoal-like substance devoid of petroleum. This innovative technique, achieved through pyrolysis, holds the promise of ushering in a new era of environmental stewardship.
The research team meticulously sourced food waste, primarily bread, vegetable scraps, and fruit peels, from the university campus for their experiments. Employing a fixed-bed tube reactor alongside the pyrolysis method, the researchers subjected the food waste to controlled temperatures and nitrogen levels, resulting in the production of biochar over an hour-long pyrolysis cycle.
“Biochar is a game-changer. It’s a solid fuel with a high carbon composition, akin to low-grade coal,” Dr. Trairat emphasized, highlighting the potential of this breakthrough innovation.
This novel technique not only offers a sustainable solution for managing food waste but also presents a cost-effective fuel alternative for various industries. By repurposing food leftovers into biochar, factories can significantly reduce disposal costs while securing an affordable fuel source.
Moreover, the implications of this discovery extend beyond economic benefits. Dr. Trairat underscored its potential for promoting sustainability on a global scale, addressing the alarming food waste crisis plaguing nations worldwide.
With over 931 million tonnes of food waste generated globally in 2019, according to the UN Environment Programme, and Thailand contributing 9.68 million tonnes in 2022, as reported by the Pollution Control Department, the urgency to tackle this issue cannot be overstated.
Looking ahead, the KMUTT research team is determined to expand their efforts, exploring the conversion of various food waste types into biochar. Their vision extends to implementing this technique in sugar and animal food factories, with the goal of revolutionizing waste management practices across industries.
