Alright chaps, Just purchased a bio fuel processor off fleabay,bit of a bargain. Going to pick it up tomorrow night. I've rung round a couple of takeaways and restaurants to try and set up regular waste veg pickup. I've said that Ill sling them a bit for the waste,not sure what kind of money I should offer per litre,if any really?... I said I will leave a container with them to fill up and to text me when its full for me to come and collect and then drop off an empty one. The only problem is that they have informed me that they require some sort of certificate to prove that it is being responsibly disposed or recycled. I have been researching a bit and think it may be a 'ISCC' certificate i require,but i'm not sure,it's all a bit puzzling. Could anyone please tell me exactly how to get around all this,it's alot more complicated than i first thought. Just wan't to produce some cheap fuel so i can use the money i save to beef up my defender 90 with some icon upgrades and maybe even a V8 conversion!...eventually. Thanks guys,Tom.
