As per title, I've just started my 200th batch of bio.
I've only got a little one ... 80ltr batch size, but all the same it means I've produced 16,000ltrs of bio.
Working on a saving of £1/ltr, all the frustration when things go wrong, all the getting covered other peoples waste, all the dealing with rank putrefied oil, all the getting frozen to the core in winter, all the nagging about the mess in the garden, all the cleaning of spills in the car not to mention the lugging around of nearly 15 tons of tins and cubies, all starts to seem worthwhile!
I just can't work out where I spent all that money I saved!
