Biowaste to biochar: a techno-economic and life cycle assessment of biochar production from food-waste digestate and its agricultural field application (2025)
Journal Article
Gamaralalage, D., Rodgers, S., Gill, A., Meredith, W., Bott, T., West, H., Alce, J., Snape, C., & McKechnie, J. (2025). Biowaste to biochar: a techno-economic and life cycle assessment of biochar production from food-waste digestate and its agricultural field application. Biochar, 7(1), Article 50. https://doi.org/10.1007/s42773-025-00456-0

Biochar has high potential for long-term atmospheric carbon storage in terrestrial environments, contributing to meeting the UK and global greenhouse gas emission reduction targets. This study investigates the greenhouse gas emissions and techno-econ...

Journal Article
Butnar, I., Lynch, J., Vetter, S., Gamaralalage, D., Tang, Y., McKechnie, J., Foteinis, S., Rodway-Dyer, S., Röder, M., Sogbesan, S., Hastings, A., Renforth, P., Brander, M., & House, J. (2024). A Review of Life Cycle Assessment Methods to Inform the Scale‐Up of Carbon Dioxide Removal Interventions. Wiley Interdisciplinary Reviews: Energy and Environment, 13(6), Article e540. https://doi.org/10.1002/wene.540

Life Cycle Assessment (LCA) methods are increasingly used for policy decision-making in the context of identifying and scaling up sustainable carbon dioxide removal (CDR) interventions. This article critically reviews CDR LCA case-studies through thr... Read More about A Review of Life Cycle Assessment Methods to Inform the Scale‐Up of Carbon Dioxide Removal Interventions.

DECO2—An Open-Source Energy System Decarbonisation Planning Software including Negative Emissions Technologies (2023)
Journal Article
Nair, P. N. S., Tan, R. R., Foo, D. C., Gamaralalage, D., & Short, M. (2023). DECO2—An Open-Source Energy System Decarbonisation Planning Software including Negative Emissions Technologies. Energies, 16(4), Article 1708. https://doi.org/10.3390/en16041708

The deployment of CO2 capture and storage (CCS) and negative emissions technologies (NETs) are crucial to meeting the net-zero emissions target by the year 2050, as emphasised by the Glasgow Climate Pact. Over the years, several energy planning model... Read More about DECO2—An Open-Source Energy System Decarbonisation Planning Software including Negative Emissions Technologies.

Journal Article
Gamaralalage, D., Kanematsu, Y., Ng, D. K. S., Foong, S. Z. Y., Andiappan, V., Foo, D. C. Y., & Kikuchi, Y. (2022). Life Cycle Assessment of International Biomass Utilization: A Case Study of Malaysian Palm Kernel Shells for Biomass Power Generation in Japan. Waste and Biomass Valorization, 13(5), 2717-2733. https://doi.org/10.1007/s12649-021-01643-3

Palm kernel shell (PKS) is a by-product in palm oil milling during the extraction of crude palm oil from fresh fruit bunches. PKS is a promising solid fuel to replace coal with its high calorific value. As Japan is moving towards renewable power to r...
