A Bamboo Carbon Filter for Diesels Could Reduce Emissions

Cars That Think

Although the pollutant emissions of a diesel engine are less than those of a gasoline one, it still emits carcinogens, nitrous oxides, and soot. A carbon-based particulate filter Diesel engines produce more polluting particulate matter than gas engines. Entering the IEEE WIE pitch competition was one of our best decisions.

2018 Environmental Performance Index: Air quality top public health threat

Green Car Congress

Recent research cited by the EPI suggests that around five million people die prematurely every year due to air pollution, accounting for approximately one in every ten deaths annually. India and Bangladesh come in near the bottom of the rankings, with Burundi, Democratic Republic of the Congo, and Nepal rounding out the bottom five.
