Summary:ABSTRACT The final destination of solid industrial waste is one of the main environmental problems currently facing, due to its potential for contamination. With the evolution of environmental policy and awareness, the proper destination of these wastes is stimulated, seeking new technologies to fulfil the demand for the products generated. One of the solutions to this environmental problem is to use these residues as fertilizers in agriculture. The objective of this study was to evaluate the use of toxic textile residues as a substrate component of coffee seedlings and as fertilizer in the initial growth of coffee plants. The study was divided into three experiments: production of seedlings, initial growth of potted plants and in the field. In the production of seedlings, the treatments consisted of different proportions of organic compost residues from the textile industry: 0, 4, 8, 16 and 32% and a conventional treatment of seedling production. In pots and in the field, the same treatments were used with organic compound, and a conventional planting treatment. In the three experiments, plant growth and nutritional analyses were performed. The conventional treatment provided better development of the seedlings and the potted and field coffee plants for most of the evaluated parameters. The treatments between 8 and 16% of organic compost showed an acceptable development of coffee plants, demonstrating their potential as fertilizer. RESUMO A destinação final de resíduos sólidos industriais é um dos principais problemas ambientais enfrentados atualmente devido ao seu potencial de contaminação. Com a evolução da política e consciência ambiental, a destinação adequada desses resíduos é estimulada, buscando-se novas tecnologias para suprir a demanda dos produtos gerados. Uma das soluções para esse problema ambiental é a utilização desses resíduos como fertilizantes na agricultura. Objetivou-se com esse trabalho avaliar o uso de composto de resíduos tóxicos da indústria têxtil como componente de substrato de produção de mudas de café e como fertilizante no crescimento inicial de plantas de café. O estudo foi dividido em três experimentos: produção de mudas, crescimento inicial das plantas em vasos e no campo. Na produção de mudas, os tratamentos constaram de diferentes proporções de composto orgânico de resíduo da indústria têxtil: 0, 4, 8, 16 e 32% e um tratamento convencional de produção de mudas. Em vasos e no campo foram utilizados os mesmos tratamentos com
