Many thanks to Vanessa Jäger for this article about the different types of pellet heating. Residential buildings require heating to supply them with heat. In the past, these were single ovens, but today they are normally
Does the bioeconomy need science? Very critically and almost cynically, scientists are the part of our fellow citizens who play thought chess in an elite ivory tower far from reality
The article series on bioeconomy, which is currently running on BiomassMuse, has already taken a look at the origins of bioeconomy and the potential of bioeconomy. The start of a biomass diet was called
It is clear to me which is the most flexible of all bioenergy carriers: Biomethane! No other energy source based on biomass can be used in so many different ways in the electricity, heating and fuel markets. Although hardly one
