About US

Waste is not redundant, it is abundant. Organic waste is one of the largest sources of pollution, while losing valuable stored compounds and energy. This as a huge opportunity - where biomass can be processed and harnessed, we reduce the impact of waste.

Energy remains the biggest cause of anthropogenic climate change. Renewable energy sources, like solar and wind, have become cheaper and more accessible but they alone cannot tackle the existing trajectory. We aim to unleash the full potential of bioenergy for everyone, everywhere.

80% of energy consumption in agriculture comes from fertilisers. Intensive chemical use degrades our land at an alarming rate - land which would otherwise be growing our food, materials and biofuels. We aim to reverse the problems in land nutrition and soil productivity in the long run.
At Pyropower, we believe in a future where energy no longer divides, destroys and depletes. We envision a future where energy is available to everyone irrespective of their caste, nationality or financial state while sustaining nature altogether.

The power of global knowledge and milieu is our greatest gift today. That is why Pyropower aims to reach as many regions and communities as there are energy and environmental problems to solve.

The bottleneck is not just understanding, but allocating the time and resources towards designing a culture plan, implementing it and then maintaining it while scaling up.

We are a team of dreamers with different nationalities, backgrounds and perspectives, but we chase the same dream of a clean, sustainable and abundant future.
