Waste sourced bio-based substances for solar-driven wastewater remediation: Photodegradation of emerging pollutants

Application of municipal biowaste derived products in Hibiscus cultivation: Effect on leaf gaseous exchange activity, and plant biomass accumulation and quality

“…To this purpose, Loh et al (2002) proposed SPAD meter as effective tool for the evaluation of plant quality in ornamental crops. The data collected on tissue characteristics and leaf gas exchanges (Table 4 and Table 5) support the intriguing role of the biowaste derived products as photosensitizers (Bianco Prevot et al, 2011;and Gomis et al, 2014), promoters of photosynthetic activity, in agreement with Sortino et al, 2013and Sortino et al, 2014and Fascella et al (2015. This hypothesis is consistently with similar findings for humic acids (Bulgari et al, 2015 andCalvo et al, 2014), bearing structural similarities with the above biowaste product .…”

“…Sortino et al, 2013 andSortino et al, 2014 have shown that the above soluble biobased substances added to soil increased tomato and red pepper plant photosynthetic activity, growth and productivity. The same substances enhanced the photochemical degradation of organic pollutants in industrial effluent (Gomis et al, 2014). These findings suggested that they might promote either C fixation or mineralization, according to the different operational environments.…”

“…Both Si (Houben et al, 2014) and Fe (Miller et al, 1995) are known to have important role in photosynthesis. Gomis et al (2014) have proposed that Fe in the soluble compost hydrolysate is responsible of the photosensitizing properties of this material, which were demonstrated for the remediation of chemical industrial waste waters containing organic pollutants. Other works (du Jardin, 2015, Li et al, 2015 andPilon-Smits et al, 2009) report that Si is a beneficial element for plants, inasmuch as it plays a key role against several biotic and abiotic stress, and promotes plant growth and development, chlorophyll concentration and photosynthetic activity.…”

“…This is the likely reason of their multipurpose performance . Particularly relevant for agriculture are the results published by Sortino et al (2014) and Gomis et al (2014). Sortino et al, 2013 andSortino et al, 2014 have shown that the above soluble biobased substances added to soil increased tomato and red pepper plant photosynthetic activity, growth and productivity.…”

“…UV-vis/H2O2 2,9 3,2 1,1 de Fenton também pode ocorrer em condições ligeiramente ácidas com uma perda aceitável de eficiência, como já foi observado com outros poluentes (GOMIS et al, 2013;GOMIS et al, 2014;GOMIS et al, 2015b). …”
