Impact of textile sludge on the growth of red amaranth (Amaranthus gangeticus)

International Journal of Recycling of Organic Waste in Agriculture, Apr 2016

Purpose In Bangladesh, the sludge of textile effluent treatment plant has been considered as a potential environmental threat due to its huge volume and chemical content. Thus, the present study was carried out to assess the reuse possibility/potentiality of textile sludge in agricultural applications. Method Textile sludge was applied at different loading ratios (0–100 % sludge) with soil for the pot cultivation of red amaranth (Amaranthus gangeticus); subsequently, chemical analyses were carried out on the harvested plants. Results The results showed that the content of plant nutrients nitrogen (N), phosphorus (P), potassium (K) and iron (Fe) in sludge was significant compared to organic manure along with a high content of total organic carbon (TOC). The growth parameters (height, number of leaves, leaf area and root length) of red amaranth were affected by the application of textile sludge. Maximum plant growth was observed in the 100 % sludge treatment group, maybe because of the high content of plant nutrients. However, the root length and number of leaves were not significantly affected by the sludge. The plant analyses implied that addition of textile sludge did not increase the content of copper (Cu), cobalt (Co), cadmium (Cd), nickel (Ni) and manganese (Mn), but lead (Pb), chromium (Cr), zinc (Zn) and iron (Fe) content crossed the maximum permissible limit set by FAO/WHO. Conclusion Textile sludge can improve the nutrient contents of pot soil and growth of red amaranth, which is revealed by pot experiments. Therefore, it can be used as soil improver if Pb, Cr, Zn and Fe content can be controlled in the textile sludge.

This industrial sector is one of the largest consumers of water as well as the biggest producers of wastewater. In Bangladesh, different industries have emerged in the last decade producing huge volumes of effluents and about 28 % are textile and dyeing industries (Shammi et al. 2014). According to the Bangladesh government rules, every industry has an effluent treatment plant. The plants are not generally operated because of the high cost involved in treating effluents, as a result they discharge the untreated effluent to the outside environment which ultimately negatively affects human beings (Hossain et al. 2010, 2015) . During the past two decades, the reuse of treated or untreated wastewater in irrigation has been quite common in Europe, the USA, Mexico, Australia, China, India and the Near East and, to a lesser extent, in Chile, Peru, Argentina, the Sudan and South Africa (Bartone and Arlosoroff 1987) . Industrial wastewater has also been considered as a threat to the environment in Bangladesh. Researchers are looking for suitable management options for industrial wastewater, such as reuse of gamma-irradiated textile wastewater for the growth of plants (Parvin et al. 2015) . Hossain et al. (2015) used untreated industrial effluent as irrigation water for rice production, and the accumulation of heavy metals into rice plants with subsequent reduction of plant growth/yield parameters was confirmed. Another scientist applied filtered municipal wastewater for the irrigation of red amaranth to assess the feasibility of its use for agricultural purposes (Biswas et al. 2015) . However, another new problem was created, that is, along with wastewater there is another vital portion of waste, i.e. (...truncated)
