Influence of controllable variables on the composting process, kinetic, and maturity of Stevia rebaudiana residues by J. J. Castro-Fernández, A. Serrato-González, M. Ruiz-Montoya, M. J. Díaz

“…Abstract Purpose Stevia rebaudiana residues composting is studied and optimized using a central composite experimental design Methods The influence of controllable composting variables [moisture (40–70%), aeration (0.05–0.30 Lair min−1 kg−1), and time (0–50 days)] on the temperature history and the properties of the compost (pH, organic matter) produced to determine suitable composting conditions. Mass balance and emitted gases of all the composting reactors have been done. …”

High-Titer L-lactic Acid Production by Fed-Batch Simultaneous Saccharification and Fermentation of Steam-Exploded Corn Stover by Liheng Deng, Changsheng Su, Yilu Wu, Qiang Xue, Changwei Zhang, Yong Wang, Bin Wang, Di Cai

“…The results indicated that the fed-batch SSF, with a simple pH control, realized a higher tolerance of the strains to the toxic by-products of hydrolysate, in comparison to the conventional sequential hydrolysis and fermentation (SHF), allowing for 153.8 g L⁻¹ of L-LA production, along with a productivity of 1.83 g L⁻¹ h⁻¹ in a system with a total of 40% (<i>w</i>/<i>v</i>) solid loading. The mass balance indicated that up to 449 kg of L-LA can be obtained from 1 t of dried CS. …”

Surface energy balance closure over melting snow and ice from in situ measurements on the Greenland ice sheet by Maurice van Tiggelen, Paul C. J. P. Smeets, Carleen H. Reijmer, Dirk van As, Jason E. Box, Robert S. Fausto, Shfaqat Abbas Khan, Eric Rignot, Michiel R. van den Broeke

“…Accurately quantifying all the components of the surface energy balance (SEB) is a prerequisite for the reliable estimation of surface melt and the surface mass balance over ice and snow. This study quantifies the SEB closure by comparing the energy available for surface melt, determined from continuous measurements of radiative fluxes and turbulent heat fluxes, to the surface ablation measured on the Greenland ice sheet between 2003 and 2023. …”
