Our purpose built biodiesel plant is the UK’s largest processing site solely dedicated to producing biodiesel from used cooking oil. It features cutting edge technology enabling us to produce EN14214 EU specification biodiesel that is ISCC certified. Please note we are unable to supply small quantities of biodiesel for private vehicle use

Our biodiesel gives more than a 86% Greenhouse carbon saving compared to regular fossil diesel.

In addition to producing biodiesel which can be used as fuel for both diesel cars and generators we also produce bioliquid fuels which can be used to run CHP units. Working with our technology partners we can supply generators which have been modified to run on the fuel we supply.

Why our biodiesel is different

At Olleco we have been able to take the biodiesel conversion technology one step further by combining the synergetic effects of an Anaerobic Digestion (AD) plant and a biodiesel plant; which are both fed from different wastes collected from the same customer base. This exceptionally low carbon production process allows biodiesel to be produced with world class GHG savings while offering an opportunity to provide some of our customers with a closed recycling loop. 

Closed loop recycling

Our closed loop process is complex in its design but simple in its concept. The used cooking oil and food waste produced by customers is collected by our local depots and transferred in bulk to our recycling facility in Liverpool. This facility demonstrates significant advantages over similar schemes elsewhere by uniquely entwining the technological processes of AD and biodiesel conversion.

What makes it stand out is that the waste generated from UCO processing and biodiesel production is also used to feed an AD plant. This in turn creates a biogas, generating the heat and electricity required to run the conversion technology that produces biodiesel from the recovered used oils and fats.

Once produced the biodiesel, which meets the strict EU specification EN 14214, is sold to the fuel majors where it is blended for use in forecourts. Our biodiesel can also be used by customers to fuel their distribution fleets. This means our closed loop customers are able to fuel their vehicles on very low carbon biofuel made from the same oil they fried their food in! A great example of a successful circular economy model with the final product saving more than 86% GHG emissions compared to fossil diesel.

Renewable Transport Fuel Obligation (RTFO)

Under European agreements large fuel suppliers must include a small percentage of renewable fuel in the fuel they supply. This means we all get to use a small amount of renewable energy every time we fill up our cars. We are proud of the part we play in providing this sustainable renewable fuel which is used in this way. Next time you fill up with diesel think of where the biodiesel you are buying may have come from!

We set higher standards

Cutting edge technology at our Liverpool plant enables us to produce 100% high grade biodiesel which meets the standards set by EN14214 EU specifications. This is a standard not achievable by most other UK plants due to the type of technology required.

By measuring the reduction of our carbon footprint to the ISO 14064 standard we produce biodiesel that gives more than a 86% carbon saving compared to using regular fossil diesel.

The European Waste-to-Advanced Biofuels Association (EWABA)

EWABA promotes the collection of used cooking oil and supports the advanced biofuels industry at large. At the beginning of 2014 we were invited with four other handpicked companies to be an executive board member. The association was set up to lobby the European Government for the interests of our industry across Europe.

You may notice that when we talk about our Greenhouse Gas (GHG) emissions savings value for biodiesel there is a difference in the percentage. For example, in some of our news posts we mention our Greenhouse Gas (GHG) saving to be over 90% but the information on our biodiesel page says 86%. This reduction is due to a change in the method prescribed by the EU for the calculation of GHG emissions. This came into effect on 1st September 2017 but as our news articles are a snap shot in time we kept them as they are. This change has broadly affected all biodiesel manufacturers equally and only really means the reporting has changed, not the quality of our biodiesel nor the way we manufacture it.
