AIMS of the Eco-Kalan Project
To Improve the Health, Environment and Economics of Poor Communities

March 30, 2015

Dear Friends,
In the current video, I share with you the exciting developments from the partnership between the Eco-Kalan Project with the Negros Oriental Visayan Forum, the 79th Infantry Battalion and the 302nd Infantry Brigade of the Philippine Army in a livelihood program based on the Eco-Kalan and the Bingka Oven.

Since the Oct. 4, 2014 demonstration at Felipa Beach on Cooking with the Eco-Kalan and Baking with the Bingka Oven to members of SUMAPI Dumandan (http://youtu.be/RUYq7i1gQj4 ), we have learned and accomplished the following:

On December 14 -15, 2014, the Eco-Kalan Project and its partners
- set up an Eco-Kalan-C kitchen with Bingka ovens fired with wood and coconut shell charcoal and a traditional oven fired by wood for comparison; and
- officially launch the Eco-Kalan & Bingka Oven as a livelihood program for SUMAPI Dumandan under the Visayan Forum's umbrella.

In reviewing the interviews with SUMAPI members, guests and attendees at the launching, I learned about the limitations in the supply of coconut shell charcoal; restrictions in the production and supply of wood charcoal; and the seemingly unavoidable smoke when using wood as fuel for the Bingka oven. Smoke during baking can tarnish the appearance and taste of the baked product making it unmarketable.. And yet, wood is most often the fuel of choice when coconut shell or wood charcoal are not available or when wood is free for the picking.

I decided to make a clay stove which can function as a TLUD (gasifier) stove in phase 1 of the burn and as a charcoal stove in phase 2. That gave rise to the Whirly Pinay-S (2 kg wood capacity) and the Whirly Pinay-L (4 kg wood capacity) based on Kelpie Wilson's tin can Whirly Girl TLUD (Top Lit Upward Draft) stove. Our March 17, 2015 test runs with the large bingka oven using firewood in the improved Whirly Pinay (longer secondary air slits) produced clean, untarnished bingkas in all the 4 batches.

Eco-Kalan has adapted their Binkga Oven (named ofter the rice cakes that the ovens make) to use both locally available coconut charcoal and stick wood fuel.

The system uses the same oven bottom, and two different covers, one for wood and one for charcoal. Both ovens can bake high quality Bingka rice cakes, but with two different levels of particulate emissions. (Notice the soot on the wood fired oven). However, both ovens are cleaner than the hornohan stove that Eco-Kalan would like to replace.

The Bingka Oven works over a range of cooking temperatures (325 deg. F - 500 deg F) and has can cook both bingka and torta breads (with or without filling). Rebecca is anticipating that it will also work for a wide variety of other baked goods.

They have demonstrated the oven for local parents, teachers, government officials, and others. They have also reached out to people who work with remote communities that in the mountains. The first commercial production will target bakers who are preparing the bingka and torta on the more common and smokey hornohan stoves and anticipate the newer stove will give these bakers the ability to make high quality goods with lower costs and improved health.

Attached is my BINGKA OVEN fired by an Eco-Kalan-C using charcoal (oling) made from coconut shells. I have used charcoal as fuel as it burns clean. I have used firewood also but the soot that is formed inside the oven tarnishes the looks of whatever is baked in it. In the Philippines, there are many men and women who use the traditional “hornohan” for their home-based businesses of making bingka (sweet rice cake with coconut), tortas (breads filled or plain) and cakes made of cassava, ube, wheat and sweet rice. In most cases, one does not earn enough to pay for the medical costs of treating illnesses such as cancer, eye and skin infections and lung diseases which result from long term exposure to smoke and intense heat. By reducing fuel consumption and exposure to radiant heat and by removing the smoke from the cooking environment and immediate neighbourhood, the BINGKA OVEN can bring better health and higher living standards to poor families in the Philippines.
