De kern van het Anammox-proces is een groep bacteriën, die in staat zijn om ammonium zonder zuurstof en een organisch koolstof om te zetten in stikstofgas. In 2011 waren er wereldwijd elf Anammox installaties in werking.
The core of the Anammox process is a group of bacteria that are capable of converting ammonium into nitrogen gas without the use of oxygen or organic carbon. In 2011, there were eleven Anammox plants in operation worldwide.

Ten slotte zijn brandstofcellen een belangrijk onderwerp als het gaat om Duurzame Energie. Brandstofcellen kunnen waterstof en zuurstof immers zonder afvalstoffen omzetten in elektriciteit, waarop bijvoorbeeld auto’s kunnen rijden.
Finally, fuel cells are essential when it comes to sustainable energy. Indeed, fuel cells can now convert oxygen and hydrogen into electricity for cars to run on, for example, without producing any waste substances. On Chemistry Day, visitors will have the opportunity to make a fuel cell and produce electricity themselves.

And finally, fuel cells constitute a major theme where sustainable energy is concerned. For fuel cells can convert hydrogen and oxygen into electricity without formation of waste products. Cars, for example, can run on electricity so generated. Visitors to the Chemistry Day could themselves make a fuel cell and produce electricity.

In de reactor van Ceballos wordt voor het afvoeren van hitte bovendien een vloeibaar mengsel van lood en bismut gebruikt, dat door natuurlijke circulatie, dus zonder pompen, de warmte veilig afvoert. Bovendien is dit mengsel van metalen heel ongevoelig voor zuurstof of water.
In the ‘subcritical’ ADSR, the number of free neutrons produced is not enough to maintain a chain reaction. An external particle accelerator supplies the extra neutrons that are needed to maintain this process in the reactor. When a potentially dangerous situation arises, the ADSR''s particle accelerator is shut down and the number of neutrons - and thus the potential danger - quickly diminishes. Ceballos''s reactor is cooled by a liquid mixture of lead and bismuth. The use of natural circulation means that no pumps are required, so the cooling system is very safe. This mixture of metals is moreover extremely insensitive to oxygen or water.

Anammox maakt bovendien het explosieve hydrazine – raketbrandstof - voor zijn eigen stofwisseling. De Twentekanaalbacterie – die methaan kan verbranden zonder zuurstof (‘Alsof je het gasfornuis aansteekt onder water’) leeft in zuurstofloze omstandigheden, maar maakt zelf zuurstof.
Jetten – professor of Ecological Microbiology at Radboud University Nijmegen and professor by special appointment of Environmental Microbiology at Delft University of Technology – was one of the first to entice these bacteria to grow and reveal their secrets down to most detailed genetic and molecular level. And that resulted in some surprising discoveries. For example, he found that anammox bacteria have a compartmentalised cell architecture, which is very unusual for micro-organisms. Moreover, these bacteria generate the explosive compound hydrazine – which is also used as a rocket fuel – for their own metabolism. The ‘Twente canal bacterium’ (Candidatus Methylomirabilis oxyfera) which can oxidise methane aerobically (‘like lighting a gas flame underwater’) lives in oxygen-free conditions, but makes oxygen itself (oxygenic). It was previously unknown that bacteria could do this.
