According to investors, the plant will prevent 2.1 million tonnes of CO2 equivalent from being released and, over its 20-year lifetime, will save around 1.3 million tonnes of wood from landfill. There is, however, only so much waste wood available — and plenty of other potential uses for much of it, including reclaiming it for future construction. In the long run, the question of sustainable sources of feedstocks will be a central concern for any large-scale expansion of wood gasification.
