Mixtures of biodiesel and ordinary diesel are usually described using the terminology Bx, where the letter x indicates the percentage of biodiesel (by volume) incorporated into diesel. The term B5 for instance refers to a mixture consisting of 5% vol. of biodiesel and 95% vol. of conventional diesel.
The nomenclature applies similarly to mixtures of bioethanol and conventional gasoline, usually described using the terminology Ex, where the letter x indicates the percentage of bioethanol (by volume) incorporated into gasoline. The term E5 for instance refers to a mixture of 5% vol. of bioethanol and 95% vol. of conventional gasoline.
Main distributors of biofuels in Switzerland
In Switzerland, the large majority of biodiesel and bioethanol is delivered to users through major fuel distributors. In a few cases, however, biofuels are distributed directly from production sites, especially when final users wish to be supplied with pure biofuel. This situation today applies exclusively to biodiesel, and this is particularly true with companies such as Lüginbuhl (VS), Serbeco (GE), Migros Vaud (VD) or yet Goutte Récupération (VD). For legal reasons, fuel-bioethanol must transit through Alcosuisse. Alcosuisse therefore buys bioethanol from Borregaard, and the distribution is then realized either directly by Alcosuisse (essentially in the case of fleet managers), or through distributors of vehicle fuels.
The distribution of biofuels is divided between the general public and managers of vehicle fleets. The table below gives an overview of the main distributors of biofuels in Switzerland and the fuel blends distributed to service stations and vehicle fleets, as of January 2008.
Table : Main distributors of biofuels in Switzerland (situation January 2008)
Concerning the general public, biofuels are distributed in regular service stations, in the form of B5 for biodiesel and in the form of E5 and/or E85 for bioethanol. B5 is usually used in place of conventional diesel, while E5 generally replaces SP95 gasoline (less often SP98), depending on the configuration of storage and distribution facilities and/or the choice of the service station manager. E85 is most generally distributed in place of SP98 gasoline. In a limited number of stations, finally, some distributors offer B100.
The names of biofuel blends change from one distributor to another. For instance, B5 is distributed under the name "Diesel Greenlife Plus" by Migrol and "Diesel Bio5" by Flamol Mineralöl. The composition of the fuel blend is most often indicated by the distributors on the columns themselves.
While the choice of B5, E5 and E85 in large-scale distribution is dictated by existing standards on fuel quality, the supply of biofuels to fleet managers is more diversified (although still limited). This is discussed in more detail on the page about the use of biofuels.
The Biofuels Platform proposes an interactive map which allows locating distributors and producers of biofuels in Switzerland. Vehicle fleets using biofuels can also be located on this map.
Availability of biodiesel
The supply of biodiesel in Switzerland is currently very limited (less than 10 Ml in 2007). With the recent new biodiesel producers on the market, the offer should however be more consistent in 2008.
In the current legal context, the distribution of biodiesel in service stations is mainly limited to B5. Although hardly any manufacturer in Switzerland supports the use of pure biodiesel in their vehicles, some distributors (including Agrola, Flamol) however supply B100 in a few service stations.
The distribution of biofuels to fleet operators and public communities offers a larger range of products, including biofuels blends "on demand". This is particularly true for biodiesel whose conditions of distribution, storage and use are less stringent than for ethanol. Fuel blends of the Bx type are supplied primarily by fuel distributors (see table above).
The use of biodiesel fuel in vehicle fleets is detailed on the page relating to the use of biofuels.
Availability of bioethanol
In the current legal context, the distribution of bioethanol in service stations is limited to E5 and E85.
In a press release of 14 March 2006 [1], Alcosuisse announced sales of E5 in the order of 10 Ml since the beginning of the project. With the increasing number of service stations distributing this fuel blend, sales of E5 have since risen significantly and are expected to keep on increasing steadily.
Since 31 May 2005, following an agreement between Alcosuisse and Agrola, some service stations of the Landi group have been distributing E5 in the Canton of Jura (JU). This premiere in Switzerland was preceded by successful tests carried out over several years and involving vehicles belonging to public and private services (cities of Delémont and Vevey, Alcosuisse, Swisscom). The distribution of E5 is currently concentrated in the Cantons of Bern (36 stations), Jura (40 stations) and Neuchâtel (9 stations), Luzern (5 stations) and Solothurn (2 stations), mainly for logistical reasons.
More recently, Alcosuisse launched an ambitious programme of the development of E85. Consisting of 85% bioethanol and 15% gasoline, this fuel is used in special vehicles called "flexible fuel vehicles" or "flex-fuel" (often classified under the term FFV), which can run on both E85 and conventional unleaded gasoline. In a partnership with GM-Saab, Alcosuisse opened on 20 July 2006, the first service station supplying E85 to Winterthur (ZH), under the banner of Agrola [2]. The marketing of E85 is today concerned with 22 service stations located near economic centres and distributed over 11 cantons (including 5 in the Canton of Zürich, 4 in the Canton of Bern and 3 in the French-speaking part of Switzerland). The number of service stations is likely to rise soon, with 13 new stations planned in the first half of 2008.
Finally, it should be mentioned that gasoline imported to Switzerland may contain ETBE [3], an oxygenate resulting from a synthesis reaction between ethanol and isobutene. In some countries, such as Germany, France or Spain, ETBE is incorporated into gasoline (as an alternative to MTBE [4]) in order to increase the octane rating of the fuel. In Switzerland, the refineries of Cressier (NE) and Colombey (VS) presently incorporate MTBE, and the presence of ETBE in the gasoline distributed in Switzerland remains very marginal. The use of ethanol in the form of ETBE, however, is a possibility for the oil industry in the short-to-medium term [5].
The use of bioethanol blends in vehicle fleets is today limited on E5. The distribution is carried out directly by Alcosuisse (via private carriers) and/or by fuel distributors having agreements with Alcosuisse. Today, Alcosuisse supplies both fuel distributors and private clients such as Swisscom, the Police of Geneva, the Industry Services of Lausanne, etc. The use of bioethanol in vehicle fleets is detailed on page relating to the use of biofuels.
Potential biofuels demand
In order to assess the availability of biofuels at the scale of Switzerland, one must first define the consumption of diesel and gasoline in the country. The figure below shows the evolution of fuel consumption in the transportation sector in Switzerland from 1992 to 2006, expressed in Ml.
Figure : Evolution of vehicle fuels consumption in Switzerland from 1992 to 2006 (in Ml)
The total fuel consumption in Switzerland was 6'970 Ml in 2007. According to the diagrams on the figure above, the fuel consumption in Switzerland over the past 15 years, despite some slight variations, appears to be relatively stable (6'970 Ml in 2007 compared with 6'630 Ml in 1992), even more so since 2000. The share of diesel during the same period, has increased significantly to almost 34% vol. in 2007 (compared with 20% in 1992).
The two diagrams in the figure below compares the evolution of biofuels production in the EU with conventional fuel consumption in Switzerland, over the period 1992-2007. While the total fuel consumption in Switzerland was 6'970 Ml in 2007 (4'600 Ml gasoline and 2'370 Ml diesel), the production of biodiesel and bioéthanol in the EU amounted to 1'770 Ml (i.e. 38% of gasoline consumption in Switzerland) and 6'434 Ml (i.e. 272% of the consumption of diesel in Switzerland) respectively.
Figure : Production of biofuels in the EU and consumption of vehicle fuels in Switzerland from 1992 to 2007 (in Ml)
In its comments on the amendment of Oimpmin [6], the Swiss Federal Customs Administration indicates the potential consumption of biofuels in the medium term, in order to define the expected tax losses and evaluate the new tax rate applicable to regular gasoline. The quoted quantities of biodiesel and bioethanol are 40 Ml/year (i.e. 1.9% of today's diesel market) and 55 Ml/year (i.e. 1.2% of today's gasoline market) respectively.
According to the most ambitious (yet realistic) scenario of a global introduction of biofuels at a rate of 5% vol. in conventional fuels (in agreement with the European Directive 98/70/EC on the quality of fuels), the volumes of biodiesel and bioethanol amount to 120 Ml/year and 230 Ml/year respectively. These volumes would obviously be doubled in the case of a global introduction at a rate of 10% vol. (in agreement this time with the proposal for a Directive amending Directive 98/70/EC of 31 January 2007).
The demand of biodiesel and bioethanol according to the various scenarios introduced above is presented in the table below. In all the scenarios, the consumption of diesel and gasoline corresponds to those in 2007.

The scenarios presented above do not take into account the development of E85, nor the possible use of biofuels at higher rates in vehicle fleets. These two factors could contribute significantly to increase the demand of biofuels.
ETBE (ethyl-tertio-butyl-ether) is the result of a synthesis reaction between ethanol (47% vol.) and isobutene (53% vol.). According to the norm EN 228 on the quality of gasoline, it can be incorporated into conventional gasoline at up to 15% vol., in order to increase the octane level. The average incorporation rate in the EU (when it is indeed added to gasoline) is around 4% vol.
[4]
MTBE (methyl-tertio-butyl-ether) is the product of a synthesis reaction between methanol and isobutene.
