Journal Article
REYNOLDS, J., KENNEDY, R., ICHAPKA, M., AGARWAL, A., OKE, A., COX, E., EDWARDS, C. and NJUGUNA, J. 2022. An evaluation of feedstocks for sustainable energy and circular economy practices in a small island community. Renewable and sustainable energy reviews [online], 161, article 112360. Available from: https://doi.org/10.1016/j.rser.2022.112360

Maximising the use of anaerobic digestion to generate power from waste feedstocks is becoming a practical way to use waste contributing to the transition from a linear to a circular economy and reducing the carbon footprint. In addition to harnessing... Read More about An evaluation of feedstocks for sustainable energy and circular economy practices in a small island community..

Oil-based mud waste as a filler material in LDPE composites: evaluation of mechanical properties. (2022)
Journal Article
SIDDIQUE, S., NOVAK, A., GULIYEV, E., YATES, K., LEUNG, P.S. and NJUGUNA, J. 2022. Oil-based mud waste as a filler material in LDPE composites: evaluation of mechanical properties. Polymers [online], 14(7), article 1455. Available from: https://doi.org/10.3390/polym14071455

Traditionally, the drilling waste generated in oil and gas exploration operations, including spent drilling fluid, is disposed of or treated by several methods, including burial pits, landfill sites and various thermal treatments. This study investig... Read More about Oil-based mud waste as a filler material in LDPE composites: evaluation of mechanical properties..
