The solid waste treatment in cities presents major technincal system that involves various factors, such as environment, technology, people, business, education and research. This system is expected to become sustainable aspect of waste treatment system. Such was said by Kamran Rousta, lecturer and researcher at Boras University in Sweden in Waste Management System: Lesson, Learn and Possible, held at the Faculty of Engineering Universitas Gadjah Mada on Wednesday (18/8). It was a collaboration between Gama Cendikia, Cendikia Teknika and Faculty of Engineering.
To students in the Faculty, Rousta said that if various factors are combined together, Municipality Solid Waste Management Systems (MSWM) turned into a very complicated phenomenon because those factors play different roles. The MSWM is based on the types of system. As in Boras, a city in Sweden, this sytems requires men to separate the waste in the source,” he said.
This way allows people to participate and take responsibility in waste treatment. The system, however, is equipped with the required technology to get the waste. “It is only that it will be efficient when people separate the waste. Therefore, through public education, this manner can increase waste treatment in Swedish cities,” he said.
According to Rousta, the various steps that are taken will produce the right method in waste management in every community. This method will be the basis for all people to participate by sorting the waste resource. This system will become the technological basis, for instance the waste treatment in Boras.
Here, the system is more emphasised on separation. The system has grown rapidly for the past 20 years, making this city at the forefront in terms of waste treatment in Sweden. “There are various bilogical treatment methods, such as incinerator for waste energy and separation of various wastes to recycle materials that are usable,” he explained.
