Trees and other fast growing plants, which are used for biomass (wood chips or pellets), are generating during growth so much oxygen that it can not be used to burn their own. Combustion will evolve gases that have minimal greenhouse effect. Ash, which remains is minimal because of complete burning (up to 1% of ash) and is also an excellent fertilizer.
That way we are completing this natural cycle- in the exploitation of fossil fuels, this is not possible, since we only waste our precious oxygen from the atmosphere and in the more polluting way. Because we love nature, we developed two types of burners named PELETKO and INTELLITHERM - first for our own needs, and later by various improvements we are also offering to you, our customers.
