Shapley-shubik index incorporated debottlenecking framework for sustainable food-energy-water nexus optimised palm oil-based complex

Palm oil mill effluent (POME) elimination has been considered recently as the alternative to expensive biogas recovery to conquer environmental criticisms in the palm oil industry involving the release of biogas (i.e., a primary contributor towards climate change), during POME treatment. With POME e...
