āThe same solution doesnāt work everywhere", Mats Eklund, professor of industrial environmental technology at LiU, points out.
The Biogas Research Center, BRC, invited researchers and representatives of the member companies to a three-day trip to Stockholm, Uppsala and VƤsterƄs.
āDevelopments in the capital are interesting since they affect the way biogas is viewed throughout Sweden. Uppsala and VƤsterĆ„s are, together with Linkƶping, pioneers, and we wanted to gain insight into their current situationā, says Mats Eklund, professor of industrial environmental technology and director of the BRC.
Linkƶping, Uppsala and VƤsterƄs are approximately the same size, with 130,000-160,000 inhabitants, and all three were early adopters of biogas technology. The preconditions and the solutions they have selected, however, differ.
The substrates that are available for biogas production differ between the cities, as do the possibilities to sell and distribute gas and biofertiliser. In addition, the cities and regions have organised their systems for waste management, water purification, energy supply and public transport in different ways.

āThe largest problem is that the motor industry doesnāt have biogas vehicles to sell: we havenāt stated this sufficiently clearly. It is important to develop the market for cars. We have also failed to emphasise that the biogas purifies the circulation and restores important nutrients. Biogas is far from receiving credit for the benefits it provides to societyā, she says.
Mats Eklund adds:
āIt has taken time, and we have often faced problems, but the cities, regions and municipalities that have stayed the course and continued to invest are important assets for society today. The next major step forwards for biogas will probably occur when several private actors with large resources enter the fray and increase their undertakings.ā

Substrates differ
āThe same solution doesnāt work everywhere, and what works best in one location is often completely unsuitable at anotherā, says Johan Laurell, head of the waste management division at Uppsala Vatten.The substrates that are available for biogas production differ between the cities, as do the possibilities to sell and distribute gas and biofertiliser. In addition, the cities and regions have organised their systems for waste management, water purification, energy supply and public transport in different ways.
Challenges
Maria GardfjƤll, head of Uppsala Vatten and newly elected member of parliament for the Swedish Green Party, realises that the future of biogas use is still facing challenges.āThe largest problem is that the motor industry doesnāt have biogas vehicles to sell: we havenāt stated this sufficiently clearly.
