“…As características do solo utilizado podem ser observadas na Tabela 1. Os vermicompostos utilizados neste estudo foram aqueles produzidos a partir da vermicompostagem de substratos constituídos de 20% de lodo de curtume e 80% de esterco bovino, os quais foram produzidos conforme descrito em Malafaia et al (2015b). É importante destacar que a empresa concedente dos lodos trata os efluentes gerados na etapa de curtimento do couro bovino separadamente dos demais resíduos e efluentes produzidos.…”

“…No entanto, a aplicação desses resíduos de forma "in natura" no solo tem causado controvérsias e resultados divergentes em diferentes culturas agrícolas, uma vez que, em função das características químicas destes resíduos, os mesmos podem influenciar negativamente as características do solo (incluindo sua biota) e não apresentar efeitos desejáveis nas culturas. Para tanto, autores como Vig et al (2011) e, mais recentemente, Malafaia et al (2015a;2015b) sugerem que o material seja previamente vermicompostado, a fim de evitar a contaminação do solo, transformando tais resíduos em compostos orgânicos nobres.…”

No presente estudo objetivou-se analisar o teor de macro e micronutrientes de folhas de milho (Zea mays L.) cultivado em solo fertilizado com vermicomposto de lodo de curtume e irrigado com água residuária doméstica. O arranjo dos tratamentos consistiu em um fatorial 2x6, sendo dois tipos de irrigação: água de abastecimento (A) e água residuária doméstica (R); e seis tipos de adubação: T1: Solo controle, sem adubação química e sem vermicomposto; T2: Solo + NPK; T3: Solo + vermicomposto de lodo primário; T4: Solo + P + vermicomposto de lodo primário; T5: Solo + P + vermicomposto de lodo de caleiro e T6: Solo + vermicomposto de lodo de caleiro, em delineamento inteiramente casualizado (DIC), com cinco repetições. Para a análise do tecido foliar coletou-se, de cada planta, a folha inteira oposta e abaixo da primeira espiga (superior), excluída a nervura central por ocasião do aparecimento da inflorescência feminina. Os resultados apontam que tanto a água residuária quanto o vermicomposto de lodo de curtume constituem boa fonte de nutrientes para as plantas de milho, uma vez que os teores de macro e micronutrientes nas folhas mostraram-se satisfatórios, não tendo sido observado nenhum sinal ou sintoma de toxidez. Apesar de certa fragilidade da análise foliar servir como ferramenta exclusiva para avaliação do estado nutricional das plantas, este estudo, pioneiramente, aponta para a potencialidade do uso da água residuária de origem doméstica e de vermicomposto de lodo de curtume (em associação) na cultura do milho, motivando a realização de novas pesquisas.

“…The physical-chemical and chemical characterization of the soil samples (Table 1) was made following the method described in Embrapa (1997). The vermicompost used in this study were those produced from vermicomposting substrates made up of 20% of liming and primary tannery sludge types and 80% of cattle manure (Malafaia et al, 2015) (Table 1).…”

The use of organic solid waste/effluent has currently been increasingly enhanced. A waste and effluent currently produced on a large scale that have potential for use in agriculture refers to sludge tannery and wastewater, respectively. However, in Brazil these residues are still little used and there is great reluctance to use them in general agriculture. Thus, this study aimed to evaluate the characteristics of an Oxisol after maize cultivation (Zea mays L.) using tannery sludge vermicompost and irrigation with wastewater. After 120 days of cultivation, soil samples were collected for analysis of the: pH, electrical conductivity (EC), total organic carbon (TOC), base saturation (BS), organic matter (OM), N, P, K, Ca, Mg, Cu, Fe, Mn, and Zn. The values for these parameters were compared between the various treatments, as well as the values observed in the soil prior to cultivation. It was observed that the tannery sludge vermicompost and irrigation with wastewater, provided little increase in pH, EC, TOC, base saturation, OM, N, P, K, Cu and Fe compared to their concentrations originally identified in the soil. Moreover, tannery sludge vermicomposts and wastewater constitute good sources of Ca, P, Mg, Mn and Zn, being able to increase the content of these elements in the soil.

“…Malafaia et al employed vermicomposting on different types of tannery sludge (liming and primary) mixed with cattle dung in various proportions. 75 It was observed that the concentrations of nitrogen, potassium, calcium, magnesium, and sodium had increased, but the total organic carbon and C:N ratio had decreased in the vermicomposts produced from both types of tannery sludge. They further explained that the vermicomposting of primary sludge at higher concentration led to a lower concentration of copper, while vermicomposting of liming sludge at higher concentration resulted in higher concentrations of all other elements.…”

Currently, industrial sludge is generated in large amounts. Industrial sludge is a solid or semi‐solid material consisting of all compounds removed from wastewater, as well as any substances added to the biological and chemical operation units during the treatment process. The composition of sludge may vary considerably. Furthermore, distinctive treatment and disposal methods are necessary as sludge produced from different industries has different characteristics. Therefore, processing and disposing of industrial sludge is a challenging and complex environmental problem. Landfilling, incineration and agricultural land application are the three most commonly employed methods for the disposal of industrial sludge. Among the three methods, the agricultural land application is a convenient and economical disposal alternative for industrial sludge. However, industrial sludge could have high putrescible content and pathogenic hazards. One possible way to ensure that the industrial sludge could be reused on agricultural land is by conditioning and stabilizing the sludge using a pretreatment process. One of the pretreatment processes which could be employed in this context is vermicomposting. Vermicomposting is an alternative for biological stabilization of organic wastes, with the addition of earthworms. Through vermicomposting, industrial sludge could be transformed into matured organic fertilizer or vermicompost in a shorter period. Thus, this work reviewed the recent literature on utilizing the vermicomposting process to manage industrial sludge in order to assess the feasibility of this technology. The present review also provides a brief overview of the production and treatment methods of industrial sludge. © 2017 Society of Chemical Industry
