Sustainable valorisation of coffee milling waste into urea-loaded biochar: physicochemical characterization and short-term aqueous urea release study

Influence of biochar mass on solids removal efficiency and biochar transformation during anaerobic digestion of palm oil mill effluent

Palm oil mill effluent (POME) is a high-strength organic wastewater that poses significant environmental challeng - es, yet holds substantial potential for biogas generation through anaerobic digestion (AD). This study investigated the influence of biochar mass loading (0, 1, 1.5, and 2 g/L) on solids removal efficienc...

Co-pyrolysis and characterization of Prosopis juliflora, coffee husk, and LDPE as a strategic waste-to-energy pathway for high-grade bio-oil production

The integrated biomass-plastic waste valorization route represents a versatile strategic framework for advancing circular economy solutions tailored to the production of sustainable transportation fuels. The present study evaluated the synergistic non-catalytic co-pyrolytic behavior of a ternary blend comprising Prosop...

Transforming olive mill solid waste: innovative biochar production for sustainable organic pollutant removal in olive mill wastewater treatment

Olive mill wastewater (OMW) is characterized by a high organic load and complex composition, requiring efficient and sustainable treatment strategies. This study investigates the potential of biochar (BC) derived from olive mill solid waste (OMSW) as an adsorbent for the removal of total phenols (TPh) and chemical...

Production of tailored bio-oils and biochars via catalytic co-pyrolysis of barley spent grains-spent coffee grounds waste cooking for prospective application in bio-asphalt formulations.

Sustainable Products from Forest Biomass: Biochar and Bio-Oil via Slow Pyrolysis from Eucalyptus Waste

Pyrolysis is a promising thermochemical conversion method that can produce solid, liquid or gaseous products from forest biomass. In this study, eucalyptus wood chips were processed using slow pyrolysis in a prototype-scale agitated reactor. Batch pyrolysis was carried out on a 100 g sample of biomass with a heating ra...

Kikuyu grass clippings as a bioeconomy feedstock: influence of pyrolysis conditions on biochar properties and its effect on the growth of Swiss chard

The integration of urban organic waste streams into the bioeconomy is critical for advancing the water–food–energy nexus. Grass clippings, an abundant and underutilized municipal residue, represent a promising feedstock for producing value‐added materials. This study provides a comprehensive evaluation of biochar p...
