Book 3 - Technology, use and potentialities of Latin American starchy tubers Chapter 18. Starch-based plastics Olivier Vilpoux1 & Luc Introduction Brazil disposes of approximately 240,000 tons of waste per day, an amount lower than that in the USA (607,000 ), but fairly above those in countries such as Germany (85,000 ) and Sweden (10,400 ). Of that total, a large amount goes to open waste deposits. Only a small quantity is disposed of in appropriate places. A city like S o Paulo spends, per day, US$ 300,000 with waste. According to the Instituto de Pesquisas Tecnol gicas IPT (Institute of Technological Research), only few munici- palities have specific teams and public policies engaged in dealing with the waste. When it is not treated, waste becomes a serious sanitary problem, since it exposes the community to illnesses like diarrhea, amebiasis, and parasitosis, apart from contami- nating the soil, waters and water tables. Among solutions, there are the creation of sanitary landfills in appropriate places, adoption of selective collecting and recycling programs, conducting of campaigns with the aim of both making society conscious about the problem and demanding a greater participation of government authorities (Editora Abril, 2002).
