We’re happy to publish roket stoves by Joshua Guinto from Philippines!

Amazing different designs from Joshua – here in the shape of a fish, truck and a human face!

Here are some interesting words from Joshua:

It is a mixture of clay that i have in stock. I mixed 3 parts of dry and sifted clay with 2 part of dry coco peat (coconut dust) and 1.5 parts water. I had them mixed in my pendulum mixer and packed them in two PVC pipes as molds.

Here in my place, we have so much green coconut shells at the market place as waste. They are dumped on open lots and is contributing to the risk of dengue infestation as they collect stagnant water for the pregnant mosquitoes. I think, it will be nice to have them shredded, mixed with paper pulp or starch and formed into briquettes.

Another plan is to revive my solar dryer for drying the briquettes. Here in the Philippines, there are intermittent rains in a single day so that will also be necessary. I have made several models of them before… and now there are new reasons to build the dryer again.

  1. I am from Daraga, Albay. Do you sell your biomass briquette stove? How much? Can I visit you and observe how you make them? Can I use rice hull as fuel? Thank you. cp 09177551401

    1. Hi Evelyn, you can find more information about briquettes in Philippines from Joshua Guinto (his email is He is a big expert in making briquettes and stoves and can hopefully visit you and demonstrate the technology and prices he can provide. You can also browse his stoves on this website under Philippines section!

      Thank you, Rok Oblak

  2. Can you teach me how to make a rice hull briquette? what’s the proportion of the materials? I tried to use rice hull as fuel for my kalan stove, but it produced so much smoke and soot, how do I avoid dirtying my cooking pans with soot?. thanks

    1. Evelyn, please contact Joshua Guinto also for this advice, i’m sure he has many experiences about briquette mixtures for you! Do you have any other materials available to make briquettes?

  3. Hi Mr. Guinto, how can I get in touch with you personally? We would like to invite you for exhibition

  4. Josh, You continue to inspire us and all the rest of the briquette producer researcher and training teams, globally. And that inspiration especially during these uncertain times becomes especially important for so many of us. Thanks very much. Richard Stanley /
