re:char – Second Season results!

Another successful year in Kenya! Well done guy’s!

I’m excited to announce that the results of our second season biochar trials in Kenya are now compiled, and we have observed some very interesting trends. You can view the results on our blog, but to summarize it appears that our biochar actually  has a lasting impact, year to year, on soil health. We applied biochar at various concentrations produced using our Rutuba Kiln to our test plots in season 1, and then fertilized with a zero-cost organic fertilizer (sanitized human urine). At harvest, we observed a nearly 26% improvement in crop yield when compared to chemical fertilizers. In season 2, we did not reapply biochar, only zero-cost organic fertilizer. Amazingly, our crop yields actually increased in season 2 above the levels observed in season 1.


These impacts are very surprising, and indicate that biochar has an effect on soil health and productivity that lasts beyond the first season of application. This means that when a farmer uses biochar, he is making a long-term investment in his soil. We are very proud of these results, as we have designed our Rutuba Kiln to produce the highest quality biochar with the highest soil stability.Thanks to The Economist, I will be presenting these results in Amsterdam to an esteemed panel of agribusiness CEOs at the end of the month who are committed to supporting new technologies to feed the world. In order to produce enough food to support a growing population, we must continue to develop new agricultural technologies like biochar. We thank you for your continued support of our mission, and hope that you will share these results with friends or colleagues. For more information click here

Negative Emission Technologies: Community Launch Event.

Negative Emission Technologies: Community Launch Event
Wed 13 Mar 2013 – Royal Academy of Engineers, London.

Event Summary

The UK is committed to reducing its greenhouse gas emissions by at least 80% by 2050, relative to 1990 levels. We need a transformation of the UK economy while ensuring secure, low carbon energy supplies to 2050, and face major choices about how to do this.

The Negative Emission Technology group has been established to stimulate and support the development of Negative Emission Technologies. Negative Emission Technologies are the deliberate manipulation of the environment to combat or counteract climate change. They are technologies which remove CO2 from the atmosphere in an attempt to avoid climate tipping points which would otherwise be triggered by the emissions that have already been produced.

Due to the nascent state of these technologies there are many challenges that still need to be addressed including; technical capacity and scalability, controllability, side effects, energy requirement and cost. It is hoped that by raising awareness of the potential for NET in meeting the UK’s carbon reduction targets future collaborations will solve these challenges and create new opportunities for the UK.

This event will provide your business/organisation with an overview of potential for NETs in the UK and will provide an opportunity to discuss the challenges and opportunities

Event objectives:

The aims of this workshop are to:

Present information about the different negative emission technologies
Provide an opportunity for networking
Identify the next steps

Who should attend?

The free event will be of interest to SMEs, research organisations and consultants working in the carbon sector.

Topics for the day

The event will provide an introduction to the negative emission technologies, namely ocean iron fertilisation, air capture, bioenergy with CCS, bioenergy with biochar and enhanced weathering/mineral carbonation.

There will also be an opportunity to hear from policymakers and leading academics on the opportunities and challenges associated with negative emission technologies and Geoengineering in general i.e. social impacts, impacts on biodiversity and engineering challenges.
