We are offering biomass briquettes. Bio coal briquettes are cheaper than coal. Oil, coal or lignite, once used, cannot be replaced. High sulfur content of oil and coal, when burnt, pollutes the environment. There is no sulfur in briquettes. Bio coal briquettes have a higher practical thermal value and much lower ash content (2-10% as compared to 20-40% in coal). There is no fly ash when burning bio coal briquettes.
