“…In a previous study, improved heavy metal–stressed plant growth by biochar was reported ( Seneviratne et al., 2017 ). It is known that MSW biochar serves as an advantage for the soils that affirmed both chemically and biologically ( Gunarathne et al., 2019 ; Jayawardhana et al., 2018 ). Ayiania et al.…”

“…Nowadays, a large quantity of municipal solid waste (MSW) (1.3 billion tonnes per year) is generated and appraised to augment up to 2.2 billion tonnes per year in 2025 with increasing global population, urbanization, industrialization, and a shift in consumption behavior, especially in developing countries ( Hoornweg and Bhada-Tata, 2012 ; Lohri et al., 2017 ). The conversion of MSW to biochar has been proven to be an environmentally logical approach to alleviate negative impacts of pollutants from the MSW and manage waste instead of getting them evacuated in landfill site ( Gunarathne et al., 2019 ). Chemical analysis of MSW biochar has also shown that the concentration of potentially heavy metals (toxic elements) and polycyclic aromatic hydrocarbon in the material is minimal and no restrictions have been reported on their use ( Gunarathne et al., 2019 ; Jayawardhana et al., 2019 ; Taherymoosavi et al., 2017 ).…”

The potential of MSW biochar to remove heavy metals from both soil and aqueous media and improve soil traits and plant growth has been previously investigated ( Agrafioti et al., 2014 ; Gunarathne et al., 2019 ; Jin et al., 2014 ; Taherymoosavi et al., 2017 ).…”

A pot experiment was carried out to evaluate the effect of a municipal solid waste (MSW) biochar and a bacterial strain on the forage maize growth and the concentration of lead (Pb) and cadmium (Cd) in the edible tissue of maize irrigated with water contaminated with Cd (5 mg L −1 ) and Pb (100 mg L −1 ). Experimental treatments included (i) bacterial strain at two levels: no bacterial strain and Enterobacter cloacae R7; (ii) MSW biochar at three levels: 0, 1, and 3% ( w/w ); and (iii) irrigation water quality at five levels: plants irrigated with 100% freshwater (FW), plants irrigated with 75%FW + 25% contaminated water (CW), plants irrigated with 50%FW + 50% CW, plants irrigated with 25%FW + 75% CW, and plants irrigated with 100% CW. The effect of various treatments on maize growth indices and concentration of Pb(II) and Cd(II) in the plant was significant at 5% level. The concentration of these metals in the shoot of plants irrigated with 75 and 100% CW was higher than the permissible limits for Cd(II) and Pb(II) in livestock feed. However, the concentration of these metals in the shoot of the plants irrigated with 25 and 50% CW was lower than the permissible limit for this use. In this study, the combined application of 3%biochar and E. cloacae R7 had a significant effect on increased root dry weight (ranging from 29 to 33%), shoot dry weight (ranging from 32 to 43%) and bacterial root colonization (ranging from 33 to 53%) and on reduced concentration of Pb (ranging from 78 to 80%) and Cd (ranging from 72 to 76%) of the shoot of maize plant (edible tissues used by livestock), which was below the permissible limits for livestock feed, compared to corresponding controls. According to the results of this study, to reduce the concentration of the heavy metals in forage maize shoot (below the permissible limits for livestock feed), it is suggested using heavy metal–contaminated water either in combination with freshwater (50 or 75% FW) or in combination with biochar and bacterial biosorbent, averting human/animal health risk.

“…In many countries, the use of waste as a raw material for other products is shrunk by regulations that prevent material transport and marketing. Changing these regulations typically leads to conflicts between stakeholders (Gunarathne et al 2019 ). Similar conflicts arise when diverting biogenic waste streams from use in energy and composting to other uses (Nanda and Berruti 2020b ).…”

“…Furthermore, with pyrolysis for bio-oil purposes, the yield of biochar ranges from 20-47% [60]. Assuming biochar yield at 30%, to produce the same amount of biochar used sufficiently for the horticulture industry (assuming replacing 50% of peat moss), nearly 0.28 M m −3 of agriculture waste can be converted annually, which otherwise would be incinerated and aggravate global warming [61].…”

Biochar (BC) has the potential as a peat moss alternative for container plant growth. Three experiments were conducted to evaluate the effects of mixed hardwood BC, compost types, mycorrhizae, and fertigation on container-grown tomato and pepper growth. In experiment 1 (Exp1), BC at 50%, 70%, and 90% (vol.) were mixed with 5% vermicompost (VC) with the rest being a commercial peat moss-based substrate (CS) and fertigated at 200 or 300 mg L−1 N. In experiment 2 (Exp2), 80% BC was mixed with chicken manure compost (CM; 5% or 10%) and CS and fertigated at 100 or 200 mg L−1 N. In experiment 3 (Exp3), 90% BC was blended with CS and fertigated at 200 or 300 mg L−1 N. Mixes in all the three experiments were added with or without mycorrhizae. Results showed that, compared with CS, in Exp1 tomato and pepper plants grown in BC-VC mixes had similar soil-plant analyses development (SPAD), growth index (GI), and total dry weight (TDW); in Exp2 and Exp3, plants in BC mixes (80% or 90%) had lower GI and TDW. In conclusion, BC (≤70%) amended with VC mixes could be used for container tomato and pepper production without negatively affecting plant growth, while BC (80%, 90%) mixes could have some negative impacts on plant growth.
