Eco-city

When the new bus was produced, the old bus body was used as an action library, a childcare center, or a bus restaurant. On the one hand, as a symbol of nostalgic
education, on the other hand, when resources are continuously recycled, the problem
of rubbish can be reduced a lot. The city of Curitiba funds “rubbish procurement
projects” and uses green exchange mechanisms to solve waste disposal problems. As
alleys in the residential areas of the poor have not been paved with asphalt, trucks that
receive garbage are unable to enter, and even regular garbage removal and
transportation work cannot be done. As a result, the city of Curitiba parked small
trucks on more than one hundred fixed points in the city. When the collection time is
up, the residents take out a bag of garbage to exchange food. For example, sixty
kilograms of garbage can be exchanged for sixty exchange cards, which is sufficient
for exchanging a month's food for the whole family (also can be exchanged for bus
tickets, school exercise books, or Christmas toys). Two kilograms of recyclable
materials can be exchanged for one kilogram of food. The vast majority of food is the
government's purchase of overproducted agricultural products from farmers. On the
one hand, it solves the problem of waste; on the other hand, it also improves the
quality of life of low-income households while also making good use of surplus agricultural products. Although former mayor Jamie Lerner humbly said that the city
of Curitiba in Brazil is a developing country, land use, transportation planning and
community participation in Curitiba are all we can learn.
