“…1 ) and also visible in the macronutrient concentration; CM addition caused significantly more P, K, Ca and Mg in the biochars, which increases their fertilisation potential. Similar trends were already observed for biochar produced through co-pyrolysis of pig manure and lignin 32 . The biochars’ P, K, Ca and Mg concentrations varied respectively between 0.4–28.3 mg/g, 2.3–34.8 mg/g, 6–182 mg/g and 1.67–14 mg/g.…”

Co-pyrolysis of chicken manure with tree bark was investigated to mitigate salinity and potentially toxic element (PTE) concentrations of chicken manure-derived biochar. The effect of tree bark addition (0, 25, 50, 75 and 100 wt%) on the biochar composition, surface functional groups, PTEs and polycyclic aromatic hydrocarbons (PAH) concentration in the biochar was evaluated. Biochar-induced toxicity was assessed using an in-house plant growth assay with Arabidopsis thaliana. This study shows that PTE concentrations can be controlled through co-pyrolysis. More than 50 wt% of tree bark must be added to chicken manure to reduce the concentrations below the European Biochar Certificate-AGRO (EBC-AGRO) threshold. However, the amount of PAH does not show a trend with tree bark addition. Furthermore, co-pyrolysis biochar promotes plant growth at different application concentrations, whereas pure application of 100 wt% tree bark or chicken manure biochar results in decreased growth compared to the reference. In addition, increased plant stress was observed for 100 wt% chicken manure biochar. These data indicate that co-pyrolysis of chicken manure and tree bark produces EBC-AGRO-compliant biochar with the potential to stimulate plant growth. Further studies need to assess the effect of these biochars in long-term growth experiments.

“…Nevertheless, absorption of C–H was rather weak, and the diminished formation of the −C–H functional group did not lead to the generation of more C–H, implying that its main conversion route was cracking. Similarly, the obvious peak corresponding to the absorption of CO (around 2190 cm –1 ) was also generated from the intensive cracking of carbonyls and other O-containing functional groups at especially an elevating temperature . The CO peak was located at around 1790 and 1705 cm –1 , representing the carbonyl in carboxylic acids/ketones .…”

Pig manure is a typical solid waste, which features a high content of inorganics. These inorganics might be involved in thermochemical conversion of pig manure, and this was investigated herein by pyrolysis of pig manure leached with varied concentrations of H 2 SO 4 (0.5−6 mol L −1 ) at 600 °C. The removal of acid-leachable inorganics [CaCO 3 , Ca 3 (PO 4 ) 2 , alkaline oxides, etc.] exposed more acidic sites derived from the oxides, like SiO 2 . This enhanced production of the gases at the expense of bio-oil. Furthermore, aromatization and secondary condensation reactions were also promoted, increasing not only the yield of char (from 29.6 to 39.7%, on an organic basis) but also the carbon content in char from 16.1% (blank sample) to 26.2% (leached with 6 mol L −1 H 2 SO 4 ). Leaching partial inorganics rendered more sufficient contact and interaction between the organics, facilitating charring of organic matter. This further retained more carbon skeleton for generation of more micropores, which further enhanced the capability of the resulting char for adsorption of phenol. In situ infrared analysis indicated the presence of more abundant oxygen-containing functionalities and carbonaceous species after the leaching treatment, favoring the occurrence of aromatization reactions.

Global agricultural by‐products usually go to waste, especially in developing countries where agricultural products are usually exported as raw products. Such waste streams, once converted to “value‐added” products could be an additional source of revenue while simultaneously having positive impacts on the socio‐economic well‐being of local people. We highlight the utilization of thermochemical techniques to activate and convert agricultural waste streams such as rice and straw husk, coconut fiber, coffee wastes, and okara power wastes commonly found in the world into porous activated carbons and biofuels. Such activated carbons are suitable for various applications in environmental remediation, climate mitigation, energy storage, and conversions such as batteries and supercapacitors, in improving crop productivity and producing useful biofuels.
