We care about nature

For every Vonken sold, we locally plant a tree. This combines gastronomic pleasures with responsible business. Which tree? We leave that up to you! Vonken’s trees are planted annually in winter with the help of experts and volunteers. 

Local production

Vonken keeps the entire production in own hands and in own region. Building our oven completely in Belgium ensures the right finishing, the right quality, and the right treatment of our suppliers.

The most economical outdoor kitchen

Burning wood emits carbon dioxide. Vonken’s ovens are designed with the aim of creating the most economical combustion possible and, at the same time, a maximum of pleasure, cooking results and cosiness. The result is a very economical outdoor kitchen with which everyone can cook responsibly. 

Is burning wood responsible?

Cooking with fire is the oldest cultural ritual of mankind. Is it still desirable though, in the 21st Century? Open fires, uninsulated outdoor kitchens and planchas are out of this time. They emit an enormous amount of carbon dioxide, have a low return, and produce a lot of fine particles and smoke as a consequence of the incomplete combustion. Due to the vast demand for charcoal and wood, beautiful forests perish in regions with vulnerable natural reserves such as in Africa and South America. Yet fire remains important to us humans: it connects us and creates unparalleled, authentic, and magical moments. Vonken holds this mission dearly. Vonken’s combustion process ensures a full combustion that creates little to no smoke, and a particular high return thanks to the intelligently placed insulation and heat retention. This generates a very low consumption, and yet a very fascinating show of flames. Do you also burn wood responsibly? 

Did you know?

  • That burning wood or charcoal emits a lot of carbon dioxide? 
  • That the production of one kg charcoal needs up to 10 kg fresh wood? 
  • That the production of charcoal is a very energy-intensive process in which approximately 1.65 kg of carbon dioxide is emitted per kg produced? 
  • That the combustion per resulting kg of charcoal is 3.65 kg of carbon dioxide and the combustion of 1 kg of dried wood only 1.75 kg carbon dioxide? 
  • That the lion’s share of charcoal is being derived from tropical forests in Brazil and Africa, regions where the EU can’t exercise sufficient control? 
  • That Vonken, thanks to strong insulation and a heat-technical design, carries out as mission to deal responsibly with outdoor cooking by utilizing a minimum of fuel for a maximum of heat retention and cosiness?
