Alternative fuels are urgently needed to mitigate greenhouse gas emissions. This study was conducted to recover bioenergy from non-edible feedstock, an oleaginous yeast biomass obtained during fed-batch cultivation of Yarrowia lipolytica. Yeast oil (lipids) was extracted from the harvested biomass and readily converted into biodiesel using the non-catalytic transesterification method.

Antibiotics in aquatic environments can foster the development of antibiotic-resistant bacteria, posing significant risks to both living organisms and ecosystems. This study explored the thermo-chemical conversion of cattle manure (CM) into biochar and assessed its potential as an environmental medium for removing nitrofurantoin (NFT) from water. The biochar was produced through the co-pyrolysis of CM and acid mine drainage sludge (AMDS) in a N condition.

Cannabinoid decarboxylation via thermo-chemical conversion has the potential to reduce the cannabinoid degradation and evaporation due to short reaction time and use of water as the solvent. When combined with pressurized liquid extraction (PLE), thermo-chemical conversion can be performed as the first stage in the extraction procedure. PLE utilizes a closed system at elevated temperatures and pressure to increase the solvation power, which contributes to decreased viscosity and increased diffusion rate.
