Coffee roasting is a highly energy-intensive process characterized by significant energy losses due to intermittent cycles that discharge heat from the stack. This paper investigates the feasibility of utilizing waste heat through combined heat and power (CHP) systems, particularly a micro gas turbine (MGT) to provide additional heat for the roasting process. The study performs energy and material balances on a rotating drum coffee roasting process augmented by hot gas recycling. A cost assessment methodology is employed to evaluate the profitability of three different system configurations integrated into the coffee roasting operation. A case study is presented based on a major coffee torrefaction facility capable of producing 500 kg/hr, under the Italian energy regulatory framework. The analysis focuses on two specific CHP configurations: (i) a regenerative topping micro gas turbine linked to the existing gas burner for hot air generation and (ii) intermittent waste heat recovery during coffee roasting. The results suggest that implementing these systems could significantly enhance energy efficiency and economic viability for coffee roasting operations.
