slaughterhouses have always been left with a residual product, once they had removed the cuts of meat we wish to eat. One-quarter of Daka's raw materials comes from animals in agricultural production, and the rest from the residual products of the slaughterhouses. The raw materials are put through a giant mincing machine, after which the water is evaporated and the fat squeezed out. From this a fat-based substance is manufactured, which comprises the basic ingredient in biodiesel. The end product is almost colourless, with an odour that could be described as half-way between rancid nuts and pork crackling. "It smells a little unusual, but not when it is used. And it has the further advantage of emitting far fewer particles into the air than ordinary diesel," says Jacob Mogensen. a CheapeR alteRnative And it is not only in Aarhus that you can drive with Daka biodiesel; in Funen some buses which run on it. Based in Aarhus, De Grønne Busser (The Green Buses) drive all across the region with a mixture of diesel and biodiesel in their tanks. The same goes for some of the milk tankers at Arla Foods, Denmarks largest dairy group. "We feel it's a question of providing the Danish transport industry with a sustainable platform. In the long run, we will all have to run on electricity there's probably no other alternative. But until the technology is sufficiently developed for us to make practical use of this in our daily operations, we will have to find a different solution in the short run. Biodiesel is a very good alternative here," says Kjær Andreasen. "We don't have enough pig waste and deepfrying fat in Denmark to completely replace fossil fuels, but it can be part of the solution," he continues. "And a cheaper part of the solution than electricity is right now". Enormous infrastructure investments will be required before we can drive using electricity around EUR 13,500 per car. Biodiesel is much easier to use with the existing infrastructure. The cost of the infrastructure investment required is less than EUR 1,350 per car corresponding to the extra cost of biodiesel during the lifetime of the car."
a good stoRy In terms of image, the switch to biodiesel production has meant a lot to Daka. The company used to be known mainly as a place on the East Jutland motorway where passing motorists would hurriedly wind up their windows and turn off the ventilaton. But now the odour from the plant has been greatly reduced, and Daka's new venture is popular. "It has given our company an image boost. Before, when our employees told people where they worked, the response might have been "Daka? That place that smells bad?", whereas now it is "Daka? Oh yes, you make biodiesel!" And that is rather more pleasant," says Kjær Andreasen. "Another good aspect of this product in relation to, for example, vegetable biomass, is that this is biomass we already have. You don't need to use a field that might otherwise have been used to grow food. That has helped to lend legitimacy to our product," he continues. So all that's left now is the prejudices, which are a bit wearying for the Daka employees. "There has hardly been a single TV item about biodiesel in buses which hasn't been accompanied by the sound of pigs grunting. It's a bit irritating. Driving with biodiesel is no more about stuffing dead pigs in your tank than shoes are about wearing dead cows on your feet. We feel it's rather more sophisticated than that." a midwife Role However, the project is not all the way home yet. The economic implications of producing biodiesel are still a long way from replacing the EUR 70 million that the slaughterhouses lost with the ban on animal proteins in animal feed production. In fact, a very long way: "We have invested EUR 24.5 million in this plant, so it's been an expensive project. And even though we're making a profit, it's still nothing like the kind of money we were making on these products before the ban. We still lack the best part of EUR 70 million to close the gap," says Kjær Andreasen with a smile. The story is also a good one for Central Denmark Region: "We have been good midwives and have helped things to happen getting Daka together with the oil industry. Now we know that the project can function on a large scale, so Daka and the oil industry can take it from here. Our role is now at an end," says Henrik Brask Pedersen.
Facts:
Biodiesel costs slightly more than traditional diesel; during the demonstration period it has cost between 9 and 20 euro cents more per litre, depending on the price of oil. however, as the amount of biodiesel in the tanks in aarhus is just five percent of the whole, the actual difference for the motorist is just 1 euro cent per litre. What's more, the use of biodiesel helps to keep the price of fossil diesel down, so in the final analysis it will probably be cheaper for the consumer. the B5next project, which is the name of the collaborative venture on biodiesel, is supported by Denmark's road safety and transport agency and the central Denmark region. apart from Daka Biodiesel, the other partners in the project are shell Denmark, the Danish petroleum association, Kuwait petroleum Danmark, oK, statoil Denmark, statoil automat Danmark, and YX energy. the project's administration is undertaken by cBMI (the centre for Bioenergy and Innovation in environmental technology). B5next has asked 100 persons in aarhus whether they would be willing to pay more for their fuel in return for a greater proportion of biodiesel in the tank. the vast majority replied that they would. Daka sells ten percent of its production on the Danish market, while the rest is sold on the international market in rotterdam. If Daka sold all its production in Denmark, it would account for two percent of the total Danish diesel consumption. together with the rape seed oil refinery in emmerlev in Funen, Daka can provide enough diesel for around six percent of the Danish consumption. eu goals require that ten percent of diesel consumption is based on biomass by 2020.
"We don't have enough pig waste and deep-frying fat in Denmark to completely replace fossil fuels, but it can be part of the solution. a cheaper part of the solution than electricity is right now."
