Catalytic torrefaction effect on waste wood boards for sustainable biochar production and environmental remediation.

Wood boards used in construction are generally treated with toxic chemicals, making them unsuitable for further use and causing environmental pollution. This study evaluates the possibility of using catalytic torrefaction as a pretreatment to improve wood pyrolysis and combustion for greener biochar production. Waste beech boards were impregnated with different KCO solutions (0-0.
