“…The high temperature reached at this stage is also crucial for pathogen reduction and disinfection. Temperatures above 55 • C are required to eliminate pathogens in organic waste (Tian et al, 2012).…”

Composting of byproducts from the orange (Citrus sinensis (L.) Osbeck) and sugarcane (Saccharum spp. hybrids) agroindustries

There is a global problem involving the generation, management, disposal, and treatment of agro-industrial waste, since it requires technologies for its transformation into the sustainable production of food, fodder, biofuels, fibers, bioproducts, and biofertilizers. The citrus and sugarcane agroindustries generate waste or byproducts that require a special treatment to be reused. Sugarcane byproducts already have an established but unsustainable use. In the case of citrus fruits, 50-60% of the organic waste has an acidic pH (3-4), 95% organic matter, and 80-90% moisture. The objective of this research was to evaluate and model the pile composting method applied to byproducts of the orange and sugarcane agroindustries to obtain compost with competitive physicochemical parameters for use as a soil improver. The pile was designed with a pyramidal rectangular arrangement, and 9 points were established for temperature sampling in three different sections during composting. An average of 55 °C and a pH of 9,1 were obtained at the end of the process. Compared to the regional control, the C/N ratio (27,5), organic matter (65,5%), and macro- and microelements show improved characteristics for use in food production in agroecological agriculture.

“…Otra posibilidad estudiada es su valorización como compost gracias a la presencia de resina melamínica que, al tener un elevado contenido en nitrógeno (66,7%) y ser este un conocido nutriente biodegradable, puede tener un efecto positivo en el crecimiento de los cultivos (Tian et al 2012). No obstante, el tratamiento para su síntesis es muy complejo y costoso, además 27th International Congress on Project Management and Engineering Donostia-San Sebastián, 10th-13th July 2023 de que no quedan realmente claros los efectos del lodo sobre el terreno y los cultivos a largo plazo.…”

Paint sludge generated in the manufacture of wind towers during painting and other coating works results in the emission of hazardous waste that is difficult to manage and whose final treatment usually ends up in landfill or incineration. In most cases, epoxy resin paint is used for this work. These resins are polymeric materials with very good adhesion and chemical resistance properties that have been increasingly studied to improve the performance of asphalt mixtures. In this work, the different applications and research currently proposed for the reuse of this waste are analysed and the possibility of incorporating them as a substitute additive for bitumen used in road pavement construction is studied

“…The major source of melamine to the STP might not be domestic wastewater, as there are numerous family clothing workshops around the STP. Textile dye wastewaters may contain MF resins as the polymers are widely used in fabric impregnation (El-Sayed et al, 2006;Tian et al, 2012), and are likely to be discharged directly along with domestic wastewaters. MF resins are generally synthesized by the polymerization of melamine and formaldehyde under alkaline conditions (pH = 8−10) (Li et al, 2018) and hydrolyse under acidic conditions (Bauer, 1982;Farmakis et al, 2020).…”
