“…Sodium contents in the studied wastes varied from 0.2 to 51.4 g kg -1 (Table 2). Highest contents were found in shrimp farming waste; therefore, its use may lead to Na accumulation in the soil and cause negative effects on chemical and physical properties and on its biological processes (Sanchéz et al, 2017). In addition, excess salinity in the soil can compromise the availability of water and nutrients to plants, directly affect the osmotic potential of the soil solution and, additionally, high level of exchangeable Na may lead to degradation of soil structure, dispersion of clays and toxicity to plants (Pereira et al, 2017 , respectively ( Table 2).…”

“…Thus, poultry agro-industry wastes and organic compost produced with wastes from small ruminants can be used as alternative complementary sources of P to the soil, especially soils of the semi-arid region, which mostly have low P contents (Souto et al, 2013). One alternative to eliminate animal waste is composting, forming organic compounds and humus (Sanchéz et al, 2017). Composting of animal waste also allows for nutrient cycling because it transforms wastes into adequate products for agricultural use (Souza et al, 2012).…”

“…With the increment in the cost of mineral fertilizers (Xun et al, 2016) and increasing levels of environmental pollution, adequate utilization of organic wastes is an alternative to supply nutrients such as nitrogen and phosphorus in smallholdings in the Brazilian semi-arid region (Rocha et al, 2013;Sanchéz et al, 2017). Recycling wastes from various production chains, whose inadequate disposal can cause negative impacts on the environment (Sharifi et al, 2016), presents itself as an important alternative to use them as organic fertilizers (Yang et al, 2017).…”

The agricultural farming activities generate organic waste whose indiscriminate deposition can be prejudicial to the environment. However, careful application of these wastes as organic fertilizers it is a possibility to improve soil fertility. This study aimed to confirm the hypotheses that organic wastes produced in various production chains in the semi-arid region of Ceará have contents of nutrients that give them potential as organic fertilizers and, since they are used as organic fertilizers, these residues improve the chemical soil attributes. Nutrient contents were determined at the laboratory and then the wastes were placed in decomposition bags and applied in a Fluvic Neosol. Soil samples were collected in the 0-0.10 m layer 90 days after wastes were applied. The residues presented nutrient contents that allow their use as organic fertilizers, except the shrimp farming residue that presented sodium content above that allowed by legislation, resulting also in higher element contents in the soil. In addition, the shrimp farming showed the lowest organic carbon content in relation to others chemical elements. The residues of the poultry industry and the compound made with residues of small ruminants presented the highest of nitrogen and phosphorus levels. The carnauba residue was associated with phosphorus immobilization because it presented C/P ratio higher than 300.

“…The sludge composting process is composed of three stages based on evolution in temperature, including the growth of mesophilic microbiota, the activation of thermophilic microbiota and the maturation phase which involves a diminution in temperature and reactivation of mesophilic population . General technologies for sludge composting include windrows composting (conventional system), aerated static piles, bunkers, and in‐vessel systems . Sludge composting is not only a good cultivation matrix and soil additive, but also regarded as a slow release fertilizer.…”

Sludge is regarded as a potential source to achieve valorization via strategies such as resource recovery, sludge based adsorbents preparation, bioflucculants production, sludge manufacturing construction materials preparation, sludge composting and thermal valorization, which are currently common and effective strategies. Appropriate treatment strategies of sludge are of great importance worldwide for the fast growing population and rapidly increasing waste. This mini review summarized some widely used and effective strategies to achieve sludge valorization based on whether the strategy would utilize or reuse the potential of sludge to obtain valuable product and eliminate secondary pollution. Anaerobic digestion of sludge is perceived as a potentially cost‐effective method to achieve sludge reduction and resource recovery including carbon, nitrogen, phosphorus resource recovery coupled with other technologies. Utilizing sludge as raw material for preparation of valuable products including sludge based adsorbents, bioflocculants and construction materials is another aspect to achieve sludge valorization. Sludge composting and thermal valorization are also introduced in the mini review since the two strategies could also achieve sludge valorization. In addition, the strategies mentioned were discussed and analyzed in the mini review from environmental and economic aspects. © 2017 Society of Chemical Industry
