A breakeven grid-emission threshold for waste-to-energy: reordering municipal solid waste pathways under Bahrain’s fossil-dependent grid
This paper establishes that for Bahrain's fossil-dependent grid, waste-to-energy incineration only becomes a net climate benefit when grid carbon intensity exceeds 0.96 kg CO₂-eq/kWh, demonstrating that material-recovery pathways consistently outperform incineration and should form the core of an integrated municipal solid waste strategy.
