“…By contrast, the stable organic carbon in water hyacinth biochar seems to increase with increasing pyrolysis temperature as indicated by the direction of oxidized carbon (OC) in water hyacinth biochar. Similar tendencies had been observed by (Masto et al, 2013;Najmudeen, et al, 2019;Hussain et al, 2020). Loss on ignition biochar organic matter (LOIOM) decreased with increasing temperature and time reflecting the increased ash content of WHB at higher pyrolysis temperatures and the ideal ash content (16.9 %) was observed at 300 °C.…”

Soil application of water hyacinth biochar as a source of nutrient-and carbon-rich biomass may be an effective ploy to eradicate this invasive aquatic weed. Incubation trial was conducted to assess effects of water hyacinth biochar addition on some sandy soil biochemical and biological properties and potential carbon sequestration at different application rates and methods. Results demonstrated that pyrolysis of water hyacinth at temperature of 300 °C and 30 min furnace residence time produced biochar with coveted physicochemical properties. Field emission scanning electronic microscopy (FE-SEM) images obtained for water hyacinth biochar showed major macroscopic changes caused by substantial changes in pore structure, surface area and surface morphology due to insufficient carbonization. Soil biochemical and microbiological characteristics after incubation exposed obvious significant improvements at all rates compared to control and varied markedly between addition of biochar as incorporation and broadcasting. Among different treatments, biochar addition as incorporation at the rate of 3% resulted in higher significant increases in most tested soil parameters. Water hyacinth biochar provided nitrogen and carbon immediately via SOC, DOC and DON in treated sandy soils providing energy for microbial biomass compared to control and this reflected by increases in soil values of C-MIC N-MIC and P-MIC. In addition, water hyacinth biocharring would greatly improve sandy soil carbon sequestration at high application rates. It could be concluded that water hyacinth transformation into biochar represents a sustainable strategy for managing these weeds and thus become a valuable organic source for sandy soils and will boost carbon sequestration.

“…Several authors reported increased body weight, growth rate, and feed conversion ratios following co-feeding with biochar at concentrations ranging from 0.004 to 4% (Moe et al 2009 ; Lan et al 2016 ; Quaiyum et al 2014 ). Najmudeen et al ( 2019 ) examined the effects of co-feeding with 0.5 and 1% water hyacinth biochar on Oreochromis mossambicus fish aquaculture and discovered an increase in fish weight and length, with the greatest increase occurring at 1% biochar content. Abakari et al ( 2020 ) investigated the influence of biochar on the tilapia bio-floc technology system.…”

In the context of climate change and the circular economy, biochar has recently found many applications in various sectors as a versatile and recycled material. Here, we review application of biochar-based for carbon sink, covering agronomy, animal farming, anaerobic digestion, composting, environmental remediation, construction, and energy storage. The ultimate storage reservoirs for biochar are soils, civil infrastructure, and landfills. Biochar-based fertilisers, which combine traditional fertilisers with biochar as a nutrient carrier, are promising in agronomy. The use of biochar as a feed additive for animals shows benefits in terms of animal growth, gut microbiota, reduced enteric methane production, egg yield, and endo-toxicant mitigation. Biochar enhances anaerobic digestion operations, primarily for biogas generation and upgrading, performance and sustainability, and the mitigation of inhibitory impurities. In composts, biochar controls the release of greenhouse gases and enhances microbial activity. Co-composted biochar improves soil properties and enhances crop productivity. Pristine and engineered biochar can also be employed for water and soil remediation to remove pollutants. In construction, biochar can be added to cement or asphalt, thus conferring structural and functional advantages. Incorporating biochar in biocomposites improves insulation, electromagnetic radiation protection and moisture control. Finally, synthesising biochar-based materials for energy storage applications requires additional functionalisation.

“…Invasive plants are rapidly expanding over the worldwide, posing a growing danger to natural ecosystems (Eviner et al 2012). They cause watercourse obstruction, dissolved oxygen depletion, water chemistry changes, and environmental contamination, rendering prospective water sources useless for economic purposes (Najmudeen et al 2019). As a result, developing new and cost-effective techniques to manage invasive species is crucial.…”

Biochar (BC) has a viable wastewater treatment agent. The invasive aquatic plant Pistia spp. was used to produce BC. Activated and non-activated BC samples were individually incorporated into a filter. Water quality parameters were measured in the experiment before and after treatment. The control filter was developed using only sand and gravel. The effect of particle sizes of BC (65-125mm and 125-250mm) and repeated treating process on treatment efficiency were carried out as optimization studies for activated BC filter. The filter unit containing activated BC showed a higher treatment efficiency. The results of the optimization study revealed that, the BC integrated filter units could be used to treat wastewater for three consecutive cycles. The BC's small particle size (65-125mm) recorded the highest treatment. This particle size showed turbidity reduction by 99.72 %. It was found that reduction of Total Phosphates, Ammoniacal Nitrogen, TSS, COD, Nitrate, BOD5 and TKN by 97.82 %, 91.49 %, 88.38 %, 88.18 %, 87.44 %, 84.38 %, and 84.38 % respectively. BC derived from Pistia spp. is a promising adsorbent for wastewater treatment. Findings of the study showed a long-term green wastewater treatment method that makes effective use of invasive aquatic plants.
