Emerging applications of biochar: A review on techno-environmental-economic aspects
Bioresour Technol. 2023 Sep 8:129745. doi: 10.1016/j.biortech.2023.129745. Online ahead of print.ABSTRACTBiomass fast pyrolysis produces bio-oil and biochar achieving circular economy. This review explored the emerging applications of biochar. Biochar possesses the unique properties for removing emerging contaminants and for mine remediation, owing to its negative charge surface, high specific surface area, large pore size distribution and surface functional groups. Additionally, biochar could adsorb impurities such as CO2, moisture, and H2S to upgrade the biogas. Customizing pyrolysis treatments, optimizing the feedstock ...

Exploring increased hydraulic retention time as a cost-efficient way of valorizing residual biogas potential
Bioresour Technol. 2023 Aug 7:129646. doi: 10.1016/j.biortech.2023.129646. Online ahead of print.ABSTRACTEffective substrate utilization with low residual methane yield in the digestate is crucial for the economy and sustainability of biogas plants. The composition and residual methane potential of 29 digestate samples from plants operating at hydraulic retention times of 13-130 days were determined to evaluate the economic viability of extended digestion. Considerable contents of fermentable fractions, such as cellulose (8-23%), hemicellulose (1-18%), and protein (13-22%), were present in the digestate dry matter. The ult...

Production of polyhydroxyalkanoates as a feasible alternative for an integrated multiproduct lignocellulosic biorefinery
Bioresour Technol. 2023 Jul 15:129493. doi: 10.1016/j.biortech.2023.129493. Online ahead of print.ABSTRACTPolyhydroxyalkanoates (PHAs) are considered an alternative to fossil fuel-based plastics. However, in spite of their interesting properties and their multiple applications, PHAs have not taken off as an industrial development. The reason is mainly due to the associated high-production costs, which represent a significant constraint. In recent years, the interest in lignocellulosic biomass (LCB) derived from crop, forestry or municipal waste by-products has been growing, since LCB is plentiful, cheap, renewable and sust...

Evaluation of anaerobic membrane bioreactor treating dairy processing wastewater: Elemental flow, bioenergy production and reduction of CO < sub > 2 < /sub > emission
Bioresour Technol. 2023 Jun 20:129342. doi: 10.1016/j.biortech.2023.129342. Online ahead of print.ABSTRACTThe management of dairy processing wastewater (DPW) must address water pollution while delivering renewable energy and recovering resources. A high-rate anaerobic membrane bioreactor (AnMBR) was investigated for treating DPW, and the system was evaluated in terms of elemental flow, nutrient recovery, energy balance, and reduction of CO2 emission. The AnMBR system was superior in terms of both methanogenic performance and efficiency of bioenergy recovery in the DPW treatment, with a high net energy potential of 60.5-66....
