Title in Portuguese
Obtenção de carvão de resíduos sólidos orgânicos alimentares.
Keywords in Portuguese
Biomassa

Carvão
Resíduos orgânicos
Abstract in Portuguese
Os resíduos orgânicos alimentares são um tipo de resíduo de difícil aproveitamento. Milhões de toneladas de lixo orgânico são descartados todos os anos, sobretudo os de origem alimentar, sendo que boa parte não é reaproveitada. Tradicionalmente, quando reaproveitados, esses resíduos são destinados à compostagem. No entanto, para que esse processo seja bemsucedido, é necessário que os resíduos sejam separados corretamente a fim de que a qualidade do produto final seja aceitável para o uso como fertilizante. Uma alternativa proposta de utilização dos resíduos alimentares consiste na produção de material carbonáceo obtido pela carbonização ou torrefação destes. Avaliam-se as propriedades e as características qualitativas e quantitativas desses materiais carbonáceos e seus derivados, como a composição, a resistência mecânica e a microestrutura. Tenciona-se, desse modo, contribuir para o conhecimento das possíveis aplicações desses carvões, materiais carbonosos e derivados em diversas áreas da indústria, inclusive na siderúrgica.
Title in English
Charcoal obtaining from organic solid food waste.

Food waste
Abstract in English
Millions of tons of organic waste are discarded every year, especially from food sources, and most of it is not reused. Traditionally, when reused, this kind of waste is destined for composting. However, for that procedure to be successful it is necessary that the waste is properly separated so that the quality of the final product is acceptable for fertilizer. An alternative reuse of food waste constitutes obtaining carbonaceous material by carbonization or torrefaction of this material. This work studies the charcoalmaking that uses these kind of residues, the characteristics of charcoals obtained, and the possible applications for these carbonaceous materials. The properties and the qualitative and quantitative characteristics of this object of study, such as its composition, its mechanical resistance and its microstructure, are evaluated. It is intended to contribute to the knowledge of the possible applications of these charcoals in several areas of industry, including in the steel industry.
