Dissertação (Mestrado em Ciências Ambientais) - Universidade Federal de Alfenas, Alfenas, MG, 2024.https://repositorio.unifal-mg.edu.br/handle/123456789/2823Composting with cigarette tobacco seized by the Federal Revenue brings numerous benefits to the population. Instead of being deposited in landfills or incinerated, this material becomes the final disposal system for solid waste without harming the environment. The tobacco itself is used as raw material for the compost, returning to the soil as nutrient-rich fertilizer, aiding in food production. It was observed that the compost reached maturity in a period of 90 days. Composting is emphasized as a viable alternative to treat tobacco waste, highlighting the acceleration of nicotine degradation in this process. Additionally, the importance of compost quality for agronomic use is emphasized, and the relevance of composting in eliminating organic solid waste is highlighted. The study also explores the phytotoxicity of the compost at different stages and discusses the characteristics of oats as a versatile crop and its importance in agricultural sustainability in Brazil. The objective of this work was to evaluate the composting process of tobacco waste from seized cigarettes mixed with soil. Chemical analyses showed that the concentrations comply with the regulations of the Ministry of Agriculture and Supply - MAPA (2014) for organic compost. Thus, it was concluded that the proposed treatment of the studied waste through different doses of cigarette tobacco achieved the expected quality, resulting in humified compost without the presence of contaminants, demonstrating efficiency.application/pdfAcesso EmbargadoResíduosMeio AmbienteComposto orgânicoComposto humificadoCIENCIAS BIOLOGICASDissertaçãoSantos, Breno Régis
