When the energy crisis collided with climate pledges two decades ago, researchers went back to basics: water, heat and plant leftovers. Today that trio has a name—hydrothermal pretreatment—and a ...

Hydrothermal carbonization (HTC) is a promising thermochemical process that transforms wet biomass into a carbon-rich material known as hydrochar, without the need for energy-intense drying. This ...

Researchers in China have unveiled a promising method to boost the carbon capture potential of biochar by integrating fly ash into the production process. The new study, published in Carbon Research, ...
