“…Large size rice straw particles were proposed to provide more reactive sites for microbes due to their enormous specific surface area and very porous structure. Accordingly, it enabled biofilm formation, a larger microbe community, and, as a result, higher organic digestion (Lap et al, 2021). The achieved removal efficiencies for BOD using treatment systems (A, B and C) were close to the results obtained by Gross et al (2006), who investigated a percent removal of 60-80%, by physical treatment systems, which usually involved some coarse filtration followed by disinfection of the filtrate for the treatment of grey wastewater.…”

The current study aimed to assess the feasibility of using agricultural waste (rice straw), along-with sand and gravel (treatment system A), to treat grey wastewater in comparison to other treatment systems (B, C, and D), which contain diverse treatment media, like sand and gravel only, activated carbon beside sand and gravel, and fired clay along-with sand and gravel, respectively, as wastewater filters. Grey wastewater samples were collected from three selected homes in Damietta Governorate, Egypt, and treated using the four different treatment systems. According to the standard methods of analyses, some physico-chemical characteristics of the grey wastewater, including: temperature, pH, turbidity, TDS, EC, NH 3 , O.P, BOD, and COD, were examined before and after the treatment. Moreover, microbiological characteristics such as TBC, TC, and E. coli were also inspected. The results showed that the physico-chemical characteristics of the treated grey wastewater via the applied treatment systems complied with the ESL for effluents discharged to the sewer systems. The outcomes revealed that the cost-effective treatment system (A) was the best in removing some physico-chemical characteristics compared to the other applied systems, especially in removing BOD, TDS, and EC with mean percent removal of 77.54±4.21%, 47.74±17.62%, and 45.84±16.96%, respectively. Simultaneously, this system achieved good elimination of Turbidity, COD, NH 3 , and OP with mean removal rates of 86.14±10.49%, 84.76±1.77%, 74.5±16.11%, and 71.77±8.12%, successively. Moreover, it has substantially removed some microbiological characteristics from the grey wastewater without disinfection and attained removal rates of 94.42% and 69.33% for E. coli and TBC, respectively.

“…For this reason, biochar has been intensively explored as a tool for carbon sequestration since the 2010s (Woolf et al, 2010). Among various biomasses, rice straw (RS) and SCG have been widely used to produce biochar due to their abundance (Andrade et al, 2020; Lap et al, 2021; Peng et al, 2011; Wu et al, 2012; Yang et al, 2022). Although biochar production can mitigate the emission of CO 2 , the additional costs required to produce biochar should be compensated for by the benefits obtained from biochar, bio-oil, and syngas.…”

The pyrolysis of spent coffee grounds (SCG) and polymers was examined as a waste treatment option for energy recovery and carbon sequestration. Rice straw–derived biochar was used as control biochar to evaluate the sorption capacity and energy production capability of SCG-derived biochar. SCG are characterised by high levels of volatile matter, rendering them suitable as an energy source. SCG were converted to biochar, bio-oil, and syngas via pyrolysis, with yields of 22%, 33%, and 45%, respectively. The high heating value (HHV) of the biochar and bio-oil was 20.6 and 22.9 MJ kg−1, respectively, indicating that they could be used as supplementary fuels. Co-pyrolysis with polymers (20 v v%−1) increased the HHV of biochar. Accordingly, the maximum production of CH4 and H2 increased from 0.3 and 0.04 mmol g−1 to 3.4−6.3 and 0.8−1.3 mmol g−1, respectively. Polystyrene most strongly enhanced the yields of CH4 and H2, followed by polypropylene and polyethylene; this order was likely to be in accordance with the number of carbon and hydrogen atoms present in the monomers. Similar to rice straw–derived biochar, the biochar produced from SCG demonstrated a high sorption capacity for 2,4-dinitrotoluene and chromate due to its high carbon content and anion exchange capacity, respectively. Laboratory pot tests revealed that the coffee grounds–derived biochar was able to increase the growth of young radish. Our results suggest that the pyrolysis of SCG and polymer may be a promising option for waste treatment, energy production, and carbon sequestration.
