After the talk offered by the neighborhood engineer Michel Maya, attendees were able to express their concerns and suggestions. These are some of them.

The people of Tramayes have easy use of wood waste.

I do not believe that Tramayes is better or worse than the other peoples. There's firewood everywhere, it's about transporting it. Our choice to use wood is no better than yours. They called me from eighty kilometers and told me: “Mr Auzapez, we have wood debris, we are ready to agree a good price.” I mean, they find it more expensive to take them out of the forest than to sell them to us. Actually, there's wood, but it's thrown in vain.

Heaters suffer breakdowns. Is it a big hurdle?

We have breakdowns, of course. Are there any impediments? There are three of us in the technical service, and I am one of them. So sometimes the technical problems become interesting. No external technician comes to us to repair breakdowns. We form the technical team and learn how to solve problems. Most of the time they're human defects, for example, we've forgotten the hammer in the oven or in the gear. They're nonsense. Of course, if the project were made available to specialists, the cost would be higher. Likewise, if we have to renew a piece device, we do not throw it immediately. We fixed it and adapted it and recovered for other people's jobs.

From the port of Baiona there are many shipments to the countries of northern Europe: they are domestic tools, timber...

They're recoverable energy sources. Why do they leave here? Probably because they're not being used. Or because in your towns or cities you don't have a heating system. You have to think about renewable energy, and wood may not come out of here. You have to exploit your wood here. Let us not fool ourselves: In France, the heat from wood is the one that provides the most energy. The calorific energy of wood provides more heat than hydroelectric plants. I believe that here in the Basque Country they do not talk enough about the use of wood energy. And it's really interesting.

But can the Tramayes heating system be applied? In the conurbation Bayonne - Biarritz?

I do not know the structure and needs of the BP, but in cities more and more energy is spreading through wood. Networks are spreading, MRLs [public housing] are heating up through heating networks. In short, through a centralized stove and a network. In Grenoble, for example, they have a network of 25 kilometres in length each. It is not at all the extension of Tramayes [people have been surprised]. It is not the only heating, of course, they are installed inside a large network.

In the environmental conferences, State agencies are in favour of this system. Wood heaters are attractive, people are used to transporting wood in private homes. Furthermore, the pollution rate of the emission of wood fireplaces is lower than that of fuel. On the other hand, the transport of local wood reduces fuel transport. In other words, there are far fewer kilometres left for wood transport, so CO2 emissions are much lower. We take the wood four kilometers away, the fuel comes back to us after hundreds of kilometers.
