Students of the Mechanical Engineering Department at the Advanced Technical Training Centre (ATTC), Bardang, have successfully demonstrated the conversion of plastic waste into crude oil through an experimental project using pyrolysis technology, showcasing an innovative approach to waste management and alternative fuel production.
The project was undertaken by a team of Diploma Mechanical Engineering students under the guidance of lecturer Bidhan Adhikari. The student team comprised Nivedan Hang Subba, Nawang Palzor Tamang, Aryan Sharma, Karma Sherpa and Prayog Sharma.
According to the institution, the initiative was designed to explore the possibility of converting plastic waste into fuel oil while promoting environmental awareness and sustainable waste management practices. The project also aimed to provide students with practical exposure to emerging technologies that address real-world environmental challenges.
As part of the experiment, the students designed and fabricated a small-scale pyrolysis unit. Pyrolysis is a process in which materials are heated at high temperatures in the absence of oxygen, causing them to break down into simpler chemical compounds.
During the trial, selected plastic waste materials were first cleaned and then placed inside a sealed reactor. The reactor was heated without oxygen, resulting in the decomposition of the plastic into hydrocarbon vapours. These vapours were subsequently directed through a cooling system, where they condensed into liquid crude oil.
The successful outcome of the experiment demonstrated the feasibility of converting plastic waste into a usable fuel product through thermal decomposition. The project highlighted the potential of engineering-based solutions in addressing growing concerns related to plastic pollution and waste disposal.
Faculty members said the exercise provided valuable hands-on learning opportunities for the students. Through the project, participants gained practical experience in fabrication, manufacturing processes, heat transfer systems, environmental engineering and alternative fuel technologies.
The initiative also enabled students to apply classroom concepts to a practical engineering challenge while enhancing their problem-solving abilities, teamwork and analytical skills.
Project guide Bidhan Adhikari supervised the work from planning and fabrication to testing and analysis. He encouraged students to continue exploring innovative technologies that can contribute to environmental protection, resource recovery and sustainable development.
