Agri-byproducts can be turned into energy sources by making pellets and heating them in an oven. The researchers found that heating the pellets at 210-250°C for 50 minutes can make them better fuel. This process reduces the pellets' weight by 7-55%, increases their heating value, and makes them less likely to absorb water. This means agri-byproducts can be a good alternative to wood pellets for heating.
