Anaerobic digestion (AD) of pineapple wastes (PW) was determined to observe its effects on biogas production when co- and tri-digested with pig manure (PM) and food waste (FW). The highest cumulative biogas yield was seen in R3 (245 mL/g VS), followed by R4 (179 mL/g VS) and R1 (168 mL/g VS), while the lowest was recorded in R2 (150 mL/g VS). Co-digestion of PW with FW showed an increase of 45.8%, while tri-digestion of PW with PM and FW had an increase of 6.55% compared to the biogas yield of mono-digestion. However, co-digestion of PW with PM decreased by 10.7%, indicating an inhibitory effect.
