A manufacturing powerhouse that's also a magnet for tourists, Penang, Malaysia is a city that's booming. But this island city is being weighed down by its own success. With the population rising, excess waste management and pollution are hindering the city's environment. Turning to green technologies and organic innovations, Penang may have found sustainable cures for their curse. Micro organic bacteria are being used to clean the rivers as well as recycle organic waste, while carbon emissions are being reduced thanks to the conversion of used cooking oil into bio diesel. Can initiatives like these help Penang maintain its environment?
