Field Study Proves: Inyenyeri Cuts Emissions 90+%, Nearing LPG Performance
Our Fuel+Stove system delivers "enormous emissions reductions compared to traditional wood and charcoal stoves...health and climate cobenefits far above other biomass stoves that have been deployed in the field, and approaching those offered by LPG."



"pellet stoves have the potential to provide health benefits far above previously tested biomass stoves and approaching modern fuel stoves (eg: LPG)"

We have known for a long time our Fuel+Stove system is incredibly clean, and now we have an independent study that shows just how powerful that impact can be.

Calling it "nearing gas-stove performance", the field study paper from NC State University says "we found that the pellet-fed stoves performed well in the field. We saw drastic cuts in pollutant emissions." Researchers found mean reduction in PM emissions from pellet-fueled stoves was 97% compared to wood fires and 89% compared to charcoal cookstoves, and that we achieved Tier 4/5 status for Co2 and PM 2.5.
And that means "pellet stoves have the potential to provide health benefits far above previously tested biomass stoves and approaching modern fuel stoves (eg: LPG). You can read the full report here.

The report also captures one of the hidden downsides of LPG: even if families can afford the stove, and a tank of fuel, they can't afford to always use it-which negates the health benefits. "The initial cost for LPG is a widely reported barrier for low-income homes, and exclusive use of the fuel is likely limited to higher- income, and often urban, users. Even if adopted, continued use of a traditional solid-fuel stove (“stacking”) for just minutes a day may negate much of the potential health benefits afforded by the modern stove."

What does that mean in practical terms? That with lower cost, locally made, renewable wood pellets, people no longer have to choose between cheap (but dirty) charcoal or clean (but expensive) LPG. It's gratifying to us--and great for our customers--to now have the proof.
Nature Energy magazine:
Inyenyeri is healthier, cleaner, and costs less
Also this month, the magazine Nature Energy published a story about some other research into our work, this time from Dr. Pam Jagger at Univ. of Michigan.   The report noted "a significant reduction in the primary cook's systolic blood pressure, self-reported prevalence of shortness of breath (indicator of respiratory illness), time spent cooking and household expenditures" on cooking expenses.
A private sector solution to improve the lives of refugees
Our ground breaking project serving the Kigeme Refugee Camp is now bringing clean cooking to more than half of the homes there, en route to 100% hopefully later this year.

This project is so successful, it's gotten our Kigeme Camp Manager Valerienne Maltemps invited to discuss it at a Paris conference on the role of the private sector in serving refugees this week and is also highlighted in this new report from the International Finance Corporation, which explores ways in which we can make hugely positive impact in the lives of the most vulnerable.
        
Customers in Kigeme *love* using our system--99% of those signed up who get an unrestricted cash transfer every month use all of it to buy our renewable pellet fuel.

When they're not at work spreading clean cooking, our Kigeme staff regularly gives back to the community. Here the team, in their signature blue uniforms, are rebuilding a mud and stick home for a women in the camp during the monthly community service known as umaganda.
Delivering more than just heat

One other point we'll be highlighting at the Paris refugee conference this week is now our solution can deliver on much more of SDG7 that just clean cooking. Since the stove has a battery to power the fan to make it work, we bundle every stove with a free, USB-enabled solar panel. After charging the stove, customers can then use to to charge their phones or LED home lights for free.

    
We're on the road-come and see us!

The Wexford Declaration on Clean Cooking
One event we just finished participating in was the Pathways to Clean Cooking 2050 conference in Wexford, Ireland. It's often noted that the biggest ideas come from the smallest places, and perhaps hereto the same is true.
 
Conferees came from around the world to highlight, debate, and propose alternatives to the often falsely binary choice presented about clean cooking--either it's dirty biomass, or clean LPG. But we all know that's not the case, and the group met to share the latest research, best practices, and innovative business models. Before leaving, they crafted the below, which will be a powerful contribution to the international dialogue on this topic.  We are honored to be adding our name to the list of signatories

Africa Calling: In Conversation with Eric Reynolds
Another remote interview this month, this time with OFR for their "Africa Calling: In conversation with" series. You can watch the video link interview here:

And in case you missed it, you really owe it to yourself to give this Good+Social podcast from last month a listen. It's a powerful,  unflinching look at mistakes made and lessons learned from almost a decade of working to solve the challenge of making truly clean cooking available to all. You can listen via Apple Podcasts, or directly on the show page.
