The study aimed to speed up compost formation from vegetable waste by adding EM 4 starter or tomato waste. They tested three solutions on vegetable waste in bags and monitored parameters like compost time, pH, temperature, weight change, and taste. The mix of tomato and EM 4 waste produced compost the fastest in 29.5 days, with normal pH, 30°C temperature, 220g final weight, and 54.375% organoleptic yield. This happened because tomato waste contains microbes that break down organic material, helping compost form quicker. Adding EM-4 and tomato waste, or both, can speed up compost formation.
