Environmental sustainability and exergy return on investment of selected solar dryer designs based on standard and extended exergy approaches

Drying kinetics and thermo-economic analysis of drying hot water blanched ginger rhizomes in a hybrid composite solar dryer with heat exchanger

“…Thus it is used in most cases for an indicative purpose. To calculate the earned carbon credit for the solar dryer we choose coal, diesel and electricity-generated power as a source of a baseline for the carbon credit because research has shown that these energy sources are the most common energy sources for artificial dryers [ 33 , 34 ]. Consequently, the carbon credit rate for the solar dryer is given by Yousef and Hassan [ 35 ], as presented in equation (9) as follows Where ƶCO 2 is the price of CO 2 globally, given as $ 14.5 per ton [ 35 ], is the yearly mass of carbon emission (ton).…”
