“…All Zn values observed are below the average value of 369 mg kg -1 , observed by Bittencourt et al (2014) for 99 batches of alkaline sewage sludge, intended for agricultural use, from 2007 to 2010 in the metropolitan region of Curitiba. For Cu values, nine alkaline sewages sludges were higher than the average 96.8 mg kg -1 obtained by Bittencourt et al (2014). However, both elements were below the total values of 3,176 mg kg -1 for Zn and 1,019 mg kg -1 for Cu, obtained by Rangel et al (2006), who Table 4 indicate a linear increase of Zn in 17 of the 20 analyzed soils after application of alkaline sewage sludge.…”

“…In Brazil, the states that most use sewage sludge for agricultural purposes are: Paraná, São Paulo and Rio Grande do Sul (Sampaio, 2010). Between 2007 and 2010 the sewage treatment plants in the Curitiba metropolitan region allocated 33,404 Mg (dry basis) of sanitized sewage sludge for use on 2,288 hectares of agricultural areas (Bittencourt et al, 2014). Studies have found that the sewage sludge have significant amounts of some elements essential to plants, such as Zn and Cu (Fia;Matos;Aguirre, 2005;Yada et al, 2015), and which can improve physical and biological soil properties (Bonini;Alves;Montanari, 2015;Mondal et al, 2015).…”

“…In Paraná, most of the sewage sludge is subjected to sanitization by a prolonged alkaline stabilization process (addition of lime aimed at raising the pH of the mixture to 12 and a curing period of 30 days) (Paraná, 2009). Thus, when applied to agricultural land, the alkaline sewage sludge has double action, it increases the soil pH (Berton;Poggere et al, 2012) and can be a micronutrients source (Smolders et al, 2012;Bittencourt et al, 2014). However, unlike mineral fertilizer, the chemical composition of sewage sludge is quite variable, which results in a high degree of uncertainty regarding the micronutrient supply.…”

In Paraná, most of the sludge generated in sewage treatment plants is subjected to the prolonged alkaline stabilization process. Although it is known that the alkaline sewage sludge contains micronutrients such as Zn, Cu and Mn, little is known about the availability of these elements in soils treated with this type of sewage sludge. Thus, the objective of the study was to evaluate the influence of alkaline sewage sludge from Paraná on Zn, Cu and Mn availability in soils. Twenty sewage treatment plants were selected throughout Paraná, where alkaline sewage sludge and the most representative agricultural soil of the each region were collected. Each soil was incubated for 60 days with alkaline sewage sludge rates (0, 10, 20, 40, ) from their region. Subsequently, Zn, Cu and Mn availability was determined using the Mehlich-1 extractant. The alkaline sewage sludge increased Zn availability and decreased Mn availability in most soils. Cu showed intermediate results, with increased availability, primarily in medium texture soils and decrease in most of the clayey soils. In soils with pH close to ideal for the plant growth, the alkaline sewage sludge rate should be carefully calculated so that there is no excessive increase in the pH and Zn, Cu and Mn imbalance.Index terms: Acid soils; organic residues; recycling; micronutrients. RESUMONo Paraná, a maioria do lodo de esgoto gerado em estações de tratamento é submetida ao processo de estabilização alcalina prolongada. Embora seja conhecido que o lodo de esgoto alcalinizado contém micronutrientes como Zn, Cu e Mn, pouco se conhece sobre a disponibilidade desses elementos em solos tratados com esse tipo de lodo de esgoto. Assim, o objetivo do estudo foi avaliar a influência de lodos de esgoto alcalinizados do estado do Paraná sobre a disponibilidade de Zn, Cu e Mn no solo. Foram selecionadas vinte estações de tratamento de esgoto ao longo do Paraná, onde foram coletadas amostras de lodo de esgoto alcalinizado e amostras do solo agrícola mais representativo da região. Cada solo foi incubado por 60 dias com doses de lodo de esgoto (0, 10, 20, 40, ) da sua região. Posteriormente, foi determinada a disponibilidade de Zn, Cu e Mn no solo usando o extrator Mehlich-1. A aplicação de lodo de esgoto alcalinizado ao solo aumentou a disponibilidade de Zn e diminuiu a disponibilidade de Mn na maioria dos solos. Já o Cu apresentou resultados intermediários, com aumento de disponibilidade basicamente em solos de textura média e com diminuição para a maioria dos solos muito argilosos. Em solos com pH próximo ao ideal para o cultivo agrícola, a dose de lodo de esgoto alcalinizado deve ser cuidadosamente calculada para que não ocorra o aumento excessivo do pH e desbalanço nos teores de Zn, Cu e Mn.

“…Although sewage sludge has a high potential for agricultural recycling, it is necessary to identify the regions of greatest potential and deepen the logistics studies in order to verify the viability of transport to these areas. When analyzing the sewage sludge recycling program in Paraná State, Brazil, Bittencourt et al (2014) observed that the distance between STS and application areas ranged from 32 to 213 km, demonstrating the possibility of working at a regional level since not always the largest generators of sludge are the municipalities with the largest agricultural production.…”

Sanitary sewage collection and treatment is a serious environmental problem in Brazilian cities, as well as the destination of solid waste resulting from this process, i.e. the sewage sludge, a substance rich in organic matter and nutrients, which is normally discarded in landfills. The aim of this study was to characterize the sewage sludge generated in four treatment stations in Rio de Janeiro State, Brazil and check if they meet the legal criteria of the National Environment Council (CONAMA), Resolution No. 375/2006. It also focused on analyzing the perspectives for its agricultural recycling based on the potential demand for main agricultural crops grown in Rio de Janeiro State. Samples from eight sewage sludge lots from four treatment stations located in the metropolitan area of Rio de Janeiro were analyzed. These stations receive and treat only domestic sewage by activated sludge system. For chemical and biological characterization of these lots, representative samples were collected and analyzed according to parameters of CONAMA Resolution No. 375/2006. In order to analyze the perspectives of agricultural recycling of sewage sludge in Rio de Janeiro State, 10 crops with the largest cultivated area in the state were surveyed and analyzed which of them are apt to receive sewage sludge as fertilizer and/or soil amendment. To determine the potential demand for sewage sludge in agriculture, the area occupied by these crops were multiplied by each fertilizer recommendation considering the sewage sludge as fertilizer. The analyzed sludge presented a high content of nutrients and organic matter and was included in the parameters of heavy metals, pathogenic agents, and bacteriological indicators stipulated by CONAMA Resolution No. 375/2006. The agricultural panorama of Rio de Janeiro State is favorable for agricultural recycling of sewage sludge since there is a great potential demand for this residue and, among the 10 agricultural crops with the largest cultivated area in the state, sludge can be used as fertilizer or soil amendment in eight of them. The implementation of a State Sewage Sludge Recycling Program could dispose of this material in a more sustainable way, as well as improve the quality of agricultural soils and reduce costs with chemical fertilizers, bringing positive results for sanitation companies and producers. Key words: Biosolid. Solid waste. Organic fertilization.
