Celtic Biodiesel

 

Biodiesel is a renewable fuel made from natural oils such as vegetable oil, used cooking oil and tallow. The process is a chemical transformation known as Transesterification. In our case, used cooking oil collected in Wales is our principal source material or feedstock.

 

The source oil is carefully filtered before being reacted under controlled conditions with Methanol and a catalyst under controlled conditions. This process breaks up the large vegetable oil molecule into three smaller molecules, which is why Biodiesel is a thinner fluid than the original vegetable oil, more like conventional diesel fuel.

 

Yes, The product you buy is perfectly legal. Biodiesel is manufactured in full accordance with local and national authorities. When you buy it, road excise duty and VAT have already been included in the price.

 

Biodiesel is non-toxic, biodegradable and has a higher flashpoint than conventional fossil diesel. It can be stored in the same conditions that are used to store conventional fossil diesel.

 

The DFIEM (Diesel Fuel Injection Equipment Manufacturers) group released a report declaring general support for the use of B5 (5% biodiesel blend). In many cases, vehicle manufacturers have individually approved up to B100 (100% biodiesel) on different models, with variations occurring over time. We therefore recommend that if you want to use more than 5% Biodiesel blend, you should refer to the manufacturer's handbook. Warranty will be unaffected if you use it in line with the manufacturer's guidance.

 

In the first instance, consult the manufacturer's handbook, however there are a number of very good websites you can visit in order to make your own mind up. One such website is:

A study published by the DEFRA (Department of the Environment, Food and Rural Affairs) showed that using even a 5% blend, some emissions such as particulates are reduced. Biodiesel has less sulphur than Ultra Low Sulphur Diesel on sale today, so emissions of toxic sulphur dioxide are negligible.

 

Biodiesel and conventional diesel can be mixed in any proportions. Bear in mind that biodiesel can be slightly heavier than conventional diesel fuel, so some agitation is needed. In many cases, adding Biodiesel and conventional diesel to vehicle fuel tanks before driving normally will be sufficient to mix the fuels. Larger quantities should be agitated to ensure full mixing.

 

Yes. Biodiesel can help reduce our dependency on fossil fuels, and contribute to the reduction in emissions of greenhouse gasses from fossil fuels.

 

By using oil that has already been used in catering as a major feedstock, we are making sure that as long as the sun shines on fields of oilseeds, we can make biodiesel from waste foodstuffs.

 

None. There is no 'conversion kit' or second tank required but pre 1996 vehicle owners should check that i.e. their fuel pipes are of sufficient quality. Pre 1996 vehicle owners can check this website by vehicle manufacturer:

You are unlikely to notice any difference driving with Biodiesel, other than to your wallet. Some users may notice a slight change in the smell of the exhaust fumes, depending on the proportion of Biodiesel in use.

 

No, there is no tax-free version, similar to red diesel. We are required to charge road use duty on all of our fuel. Agricultural and other non-road users should consult the Revenue, customs and excise department to obtain details of how they can reclaim the excise duty for off road use. We understand from Customs and Excise that it is not permitted to mix Biodiesel with Red diesel, so for the full off road rebate, we believe you would need to convert to 100% Biodiesel or not use it at all.

 

Yes, we will collect used cooking oil from any catering establishment . We do not charge for the collection. Please telephone or email to arrange collection.
