Curitiba, Southern Brazil, is considered one of the cleanest cities of the country because of two main reasons:
1. The garbage policy:
Citizens separate their trash into two categories, organic and non-organic, which is collected by two sets of trucks so that there is no mixing. Poor families in squatter settlements, unreachable by trucks, bring their trash bags to a neighbourhood centre where they can exchange the trash for bus tickets or food.

2. Transportation:
Core to the city's unique transport system is the bus service: 1 100 buses make 12 500 trips a day serving 1,3 million passengers. The buses are express buses that operate on dedicated busways; rapid buses that operate on the busways and other city streets; bi-articulated buses also for rapid transport but using high-capacity lanes; inter-district buses and feeder buses.

Curitiba is a simple city in Brazil, but its population enjoys a better quality of life than much of the rest of the world. The local economy is strong, and this little city has gone to great lengths to preserve its historic buildings. It can be considered one of the first cities that launched an “eco-friendly’ campaign, providing incentives for its residents to take public transportation from as early as the 1970’s. You can still see evidence of this effort today. Visitors to Curitiba will find that it is one of the easiest cities to navigate without a car in all of Brazil. The city’s innovation has not stopped at saving the environment; Curitiba also has displayed creativity in its approach to reducing pollution and addressing issues like poverty and homelessness. Curitiba is not one of the most beautiful cities around, but it surely is pleasant place to visit for those who enjoy fine architecture and a vibrant music scene.
