“…Other advantages are that it has high efficiency, low cost, and ease of operation. However, the disadvantages of adsorption include the need to replace adsorbent materials frequently and difficulties in regenerating adsorbent materials [3].…”

“…In several previous studies, rice husk, which is a byproduct of the rice milling process, is that waste that is available in large quantities and easily renewable has great potential as an adsorbent in removing pollutants from wastewater. Studies have shown that rice husk-based adsorbents are effective in removing dyes, heavy metals, and organic compounds from wastewater [3]. Fixed bed column studies have shown that raw rice husks, bottom treated rice husks, and thermally treated rice husks are superior to other adsorbents tested to remove pollutants from textile wastewater [4].…”

The goal of this study was to evaluate rice husks potential to decrease both organic and inorganic contaminants from textile effluent. Rice husks are added in amounts up to 38% of the total adsorption bed volume. Using a submerged flow system with a three-day HRT, the native textile effluent (diluted to 75%) was constantly pumped at a rate of 15 ml/minute. In-situ and laboratory analyses of the water quality parameters were conducted. The treated water by rice husk has met the requirements for river ecosystems with parameter values such as pH and Temperature is normal, TSS 65 mg/L, TDS 400mg/L, DO 4 mg/L, COD 200 mg/L, TN 5 mg/L, and TP 2 mg/L. TSS, COD, Ammonium, TP, and TN efficiency of removal were 86.94%, 84.19%, 67.25%, 61.24%, and 48.72%, respectively. The difference in removal efficiency can be attributed to various factors such as the nature of the pollutant, the adsorption capacity of the adsorbent, the concentration of the pollutant, and the interaction between the adsorbent and the pollutant. The wastewater treatment with rice husk is a promising approach for industrial-scale applications due to its adsorption properties and cost-effectiveness.

The reuse and reincorporation of waste are the principles of circular economies. Compost, biofuels, animal feed, dyes, and bioactive compounds can be obtained from the revaluation of organic waste. Research on this subject is scarce and limited to specific sectors, such as agriculture and agroindustry, leaving aside others that generate large quantities of organic waste, such as floriculture. The remains of these sectors have a low decomposition rate compared to other organic wastes. They are a source of bioactive compounds (e.g., essential oils, pigments, phenols) that can be reincorporated into the production chain of various industries. This review describes the composition of waste from agroindustry, agriculture, and floriculture, analyzing their potential revalorization as a source of bioactive compounds and an alternative supply source.

“…[1,2] In chemical, textile, paper, and printing industries, a huge amount of wastewater containing chemical or dye pollutants is released into the environment due to unfair treatment processes. [3][4][5][6] In these released wastewaters, the presence of certain dyes even at very low levels are very toxic and cause the death of animals and plant tissue in different regions. [7,8] The dyes consumed by the aquatic organisms can produce toxic intermediates after metabolism.…”

The mesoporous SBA‐15 was synthesized in acidic conditions by hydrothermal method using Pluronic surfactant P123. A combination of SeO2, TiO2, and CuO was loaded in SBA‐15 in pairs or singly. Synthesized SBA‐15 and some loaded mesoporous materials were characterized using several standard techniques. The efficiency of the synthesized photocatalysts was verified for the decomposition of two different dyes (methylene blue (MB) and methyl green (MG)) under ultraviolet and visible light radiation. The results show that the synthesized photocatalyst based on SBA‐15 with 5 % by weight of TiO2 and 5 % by weight of SeO2 has better performance (about 98 % of MB or MG were degraded within 120 min under UV radiation). Also, the photocatalyst with 5 % by weight of SeO2 and 5 % by weight of CuO shows a good performance for the degradation of the dyes under visible irradiation in the presence of H2O2 (complete elimination of MB and MG within 150 and 75 min, respectively). The scavenging test shows that superoxide has a governing role for the degradation of the dyes. The photocatalysts are reusable and they could preserve more than 74 % of the efficiency following 4 times of consecutive use for the degradation of the dyes.
