Technobiological Pathways for High‐CO₂ Capture Using Micro‐/Macroalgae: Genetic Engineering, Process Automation, and Value‐Added Bioproducts

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Simulating competition in the US bioeconomy to produce hard‐to‐electrify transportation fuels using limited biomass resources

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract This study presents a novel bioeconomy optimization framework, BiOpt, designed to address critical questions regarding the strategic use of limited US biomass resources for biofuel production. By integrating detailed techno‐economic analyses, life cycle assessments, and resource assessment data, BiOpt optimizes resource distributions across ...

Toward Carbon Accounting and Circular Harmony in Shipping Corporations: A Systematic Bibliometric Review

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study examines how carbon accounting can be used to govern, not merely report, circular economy principles in shipping corporations. Grounded in institutional theory and aligned with the UN 2030 Agenda, this study introduces circular harmony as an accounting design principle: Circular interventions are embedded in a single well‐to‐wake ...

From Green Governance to Biodiversity Strategy: The Role of Environmentally Experienced Directors in Chinese Firms

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study investigates how directors with environmental protection (EP) backgrounds influence corporate biodiversity concern (BIO) among Chinese A‐share listed firms from 2008 to 2023. Drawing on Upper Echelons Theory, we argue that directors' environmental expertise shapes firms' biodiversity strategies.
