answer quite easily,there are customers who have always burnt fossil fuels all their lives and are not familiar with the new Eco friendly fuels so selling peat is a great way to introducing them to an alternative .Customers who burn coal and peat will probably continue to do so but using for example  EziLite fuel briquettes with their peat or coal will mean using less peat in effect indirectly assisting ecologically with the environment and the same goes if you use eco fuels with  kiln dried logs which are carbon neutral  but using Hotmax or Blazers reduce the strain on forests so there is a way to burn all fuels with less of a conscience.
