Keep Africa Green

Who we are?


POLTANZA is a Tanzanian company founded, by the partners from Tanzania and Poland to protect natural environment, improve health and wellbeing of most vulnerable communities all over the Africa.


Wojtek from Poland and David from Tanzania came up with the idea to create simple, user friendly and affordable devices  converting organic bio-waste into briquettes. Biomass briquetting machines solve rural and urban needs by generating income, providing a new and cheap alternative source of cooking energy, avoiding excess waste disposal, preventing deforestation and ultimately promoting a sound environment.

    Tanzania and rest of the beautiful world will remain as safe place to live if we will continue to preserve the nature that created by God. If all of us will change mind of using charcoal that generated from our beloved trees as source of energy. Humanity is totally dependent on nature, and by saving nature, we’re saving ourselves.’’Tunza mazingira,mazingira yakutunze’’
