A range of energy fuels (ethanol, char, oil/wax and gas) was produced from fibre waste contaminated with plastic through the application of a fermentation-pyrolysis route. The fibre component was first converted to ethanol by simultaneous saccharification and fermentation (SSF), achieving an ethanol concentration of 39.8 g/L.

- The study focused on pyrolysis of two invasive plant species, Lantana camara and Mimosa pigra, to optimize conditions for maximum char yield and higher heating value (HHV).
- Significant findings indicated that increasing temperature positively influenced char yield and HHV, while the effects of heating rate and hold time were minimal.
- Scaling up the experiments resulted in increased secondary char formation, boosting HHVs to 30.82 MJ/kg for LC and 31.61 MJ/kg for MP, with additional factors like gas composition and temperature affects analyzed through chromatography.
The paper and pulp industry is one of the major industries that generate large amount of solid waste with high moisture content. Numerous opportunities exist for valorisation of waste paper sludge, although this review focuses on primary sludge with high cellulose content. The most mature options for paper sludge valorisation are fermentation, anaerobic digestion and pyrolysis.

Using thermogravimetric analysis, the influence of heating rate (HR: 2.18-19.
