In your area are large fields growing crops, where you always wonder what happens with the straw? You are processing palm oil, olive oil, sunflower seeds, rice or other agricultural fruits?
Then surely you have an abundance of production waste like olive pomace, rice husk, empty fruit punches, palm kernel shells and similar waste. On the other hand, these processes usually require a lot of energy.
So why not convert your waste into energy, thereby saving your expenses on fossil fuels and doing something for the environment at the same time.
