 <![endif]-->    Outro trágico fator ambiental é o lixo que em sua maioria ainda é lançado a céu aberto. No Brasil, cerca de 85% da população brasileira vive nas cidades. Com isso, o lixo se tornou um dos grandes problemas das metrópoles. Pela legislação vigente, cabe às prefeituras gerenciar a coleta e destinação dos resíduos sólidos. De acordo com o IBGE, 76% do lixo é jogado a céu aberto sendo visível ao longo de estradas e também são carregados para represas de abastecimento durante o período de chuvas. Embora muito esteja se fazendo nesta área em nível mundial, ainda são poucos os materiais aproveitados no Brasil onde é estimada uma perda de cerca de 4 bilhões de dólares por ano. Mas, há indícios de melhora na área no país onde se tem como melhor exemplo as latas de alumínio, cuja produção é 63% reciclada (COZETTI, 2001). O lixo industrial apresenta índices maiores de reciclagem. De acordo com a FIRJAN, no estado do Rio de Janeiro 36-70% das indústrias reciclam seus dejetos (BRANDÃO, 2002).  &nbsp;Cada brasileiro produz 1 Kg de lixo doméstico por dia, ou seja, se a pessoa viver 70 anos terá produzido em torno de 25 toneladas. Se multiplicarmos pela população brasileira, pode-se imaginar a dimensão do problema (COZETTI, 2001).
