Incineração de Resíduos Sólidos
Diego de Medeiros

Incineração?
Processo de tratamento de residuos através da queima. Geralmente é associado com produção de energia.
Melhor que disposição em solo (landfills
Waste that is not treated correctly = environmental damage

Main points:
3 Rs

Educação Ambiental
Separação dos resíduos
Utilização de cinzas como material de contrução

Conclusion
Research to improve technologies of incinerator’s filter

Vantagens
Redução drástica do volume a ser descartado
Destoxificação
Recuperação de energia
Diminuição no consumo de combustíveis fósseis
Reciclagem das escórias e outros inertes
Redução do impacto ambiental

Desvantagens
• Custo elevado
• Exige mão-de-obra qualificada
• Problemas operacionais
• Limite de emissões
• Composição química das emissões gasosas
• Incerteza dos efeitos das emissões
• Agressividade da matéria-prima
• Poder calorífico
• Competição com outros tratamentos
