Industrial production of activated carbon using circular bioeconomy principles: Case study from a Romanian company

This work discloses an industrial multi-ton scale methodology implemented by a Romanian company (Explocom GK) to use bio-wastes produce biochar, demonstrating case of bio-economy circularity associated with economic growth. The pyrolysis process was able ∼20%w high-quality biochar (550 m2/g) starting from forest-based and agricultural wastes. A fraction ∼60%w is converted into condensates, including wood vinegar, tar, alcohol, etc. that can be recovered purified because the large process. energy contained in volatile syngas produced (∼20%w) stored used instead fossil fuels for heating reactor. Some this vinegar also activate activated carbon (value carbon/value >3, depending on market required properties). transformation increases overall profitability plant while manufacturing product does not or chemicals activation. material locally reduce emissions transport carbons currently exported other continents.
