In this sense, silage (SG) and flue gas desulfurized gypsum (FGDG) are two good choices as composting additives. SG is made from the roughage obtained by cutting corn, sorghum, and other forage crops and grass; the roughage is then subjected to anaerobic fermentation by lactic acid bacteria, which results in the generation of SG [19].
