Editor,It was a great pleasure to read in your newspaper that the Rwanda Biodiesel Express Bus is all set to be launched. The environment, the world over, is under severe threat and only with such innovations like the biodiesel bus can we help in the preservation of nature and reduce pollution. To know, through your article, that Rwanda is the first country on the African continent to launch the biodiesel bus is very gratifying. Such unique inventions will go a long way in making Rwanda truly the land of a million smiles! Wishing the Institute of Scientific and Technological Research every success in this great initiative .
