What’s the use of recycling waste cooking oil?

Apart from the fact, that your CO2 emissions are close to nil while driving your diesel powered car, enormous savings are associated:

• Someone driving 50.000 k a year could reduce their annual fuel bill by some 80% from €3500 to €750 a year
• A car rental company, hiring their diesel cars with fuel included in the rental price, could net another €17.500, if they run ten cars doing some 300.000k p.a. Apart from giving a sound ecological image of their company to the potential client, they would bill their customers the service station rate of biodiesel, some €22.000 but the cost to produce the fuel is only €4500.
• A hotel will produce some 5200 litres of waste cooking oil p.a,, which recycled on site into biodiesel will save them €5000 p.a. and provide them with an additional 2000 lb of soap, a by-product when making biodiesel which cuts costs in the laundry.
• Boat owners know how fast their engines burn up fuel and a day trip can cost €1000 at the gas `pumps in the port. Producing your own biodiesel would reduce this to €200.
