there anre many companys in the EU that are now running on bio diesel.
mcdonalds and asda/walmart run on bio collected from there outlets,many bus companies are turning to bio,stagecoach are on bio and firstgroup have used it, as the emissions are super low on this stuff it ideal for citys where local councils are red hot on emissions.
also if a company has a low carbon footprint there is massive gains to be had with regards to tax and not getting fines.
its the way forward,as long as we can get the balance right,but i do think to myself why they have not redesigned the diesel engine do handle heavier oils like pure veg,it can be done,they just dont want to because they are hand in pocket with the oil companies it plain to see.......the first diesel engines ran on peanut oil
food for thought
