Influence of tannery wastewater sludge doses on biometric and chlorophyll fluor...
Berilli, Sávio Silva; Zooca, Alan Alvino Falcão; Ferraz, Tiago Massi; Figueiredo, Fábio Afonso Mazei Moura de Assis; Rodrigues, Weverton PereiraTannery wastewater sludge is an industrial residue that can be used in the pure form or associated to other residues, such as byproduct production from cultivated plants. The objective of the present study was to assess substrate composition for producing conilon coffee stem cuttings, varying increasing tannery wastewater sludge doses. A randomized block design was used with four treatments, three increasing do...
Chromium levels in conilon coffee seedlings developed in substrate with tannery...
Berilli, Sávio Silva; Berilli, Ana Paula Candido Gabriel; Carvalho, Almy Júnior Cordeiro de; Freitas, Silvio de Jesus; Cunha, MauraThe use of by-products of the leather processing industries in agriculture represents a major breakthrough in production processes, nutrient cycling and agro-ecological awareness. However, the use of tannery sludge as seedling’s substrate shows the presence of chromium, considered a harmful element, under specific conditions, to the environment. The experiment was carried out at the Federal Institute of Educati...
Use of sludge tannery substrate as alternative to prepare conilon coffee seedlings
Berilli, Sávio Silva; Quiuqui, Joao Paulo Chodacki; Rembinski, Jessica; Salla, Paulo Henrique Honorato; Berilli, Ana Paula Candido GabrielThe Brazilian cattle is great source of income and investments from public and private sectors, and after slaughter, the destination of the leather to tannery causes the generation of a significant amount of waste in the form of sludge, thus becoming an environmental problem for tanneries in many Brazilian states that do not have laws for proper disposal of this waste. Thus, the use of sludge in agriculture tan...
