Integrated Cooking

INTRODUCTION

Food supply often represents the largest component of aid to stressed populations in post-disaster, post-conflict and generally impoverished situations. It is therefore important that it is properly usable. One crucial aspect of this is through the provision of sustainable innovation and technology for food preparation through integrated cooking mechanisms, which can be comprised of necessary combinations of solar energy, combustion stoves and retained heat.

In most areas, fuel is scarce (as can be seen in Haiti, Afghanistan and many refugee camps). Solar cooking sometimes can help, but sunlight is not always available. As a result, integrated cooking – a combination of solar ovens, high-efficiency stoves and retained heat baskets containing stones or bricks, can significantly (up to 75-90%) reduce fuel use compared to open-pit fires. If properly tied to other infrastructures, the heat used for cooking could sterilize water, and use of hot stones or bricks for heating could reduce public health risks from smoke inhalation from open fires, especially in shelters. Lowered fuel demand could mitigate deforestation, give people more time for non-fuel-gathering activities, and reduce security risks to gatherers.

KEY RESOURCES:

Which technology and energy source(s) are compatible with an emergency environment can best be determined by evaluating all contextual variables. Towards ensuring the most effective provision of power resources and innovation in post-disaster, post-conflict and impoverished conditions, STAR-TIDES is working to provide a useful database of information for inexpensive, sustainable infrastructure that can be supplied to emergency situations and development scenarios with minimal transportation costs.

The Sphere Project www.sphereproject.org is a good resource that offers common standards used by the international community when providing support to disaster victims, refugees, and other displaced populations. Nutrition is considered to be a “basic requirement” for sustaining the lives and dignity of stressed populations. Sphere provides detailed standards for minimal nutritional support within the humanitarian relief and assistance arena. TIDES highly recommends that those involved in such operations become familiar with the Sphere Standards available at the above link.

Notes: For detailed information on all types of solar cookers go to the solar cooking archive.

Combustion:

A detailed USAID study provides the most recent evaluation of fuel-efficient stoves. The non-profit ETHOS also provides information and assessments on various fuel-efficient stoves available on the market and for local manufacture.

Retained heat:

There are currently no standards or published assessments on retained heat cookers, which can be made by stuffing a container with any insulating material (straw, grass, cloth) to surround a cooking pot with at least 10 cm of insulation on all sides. Approximate cooking times for simmering over a heat source and then sealing in a retained heat cooker are as follows:

FOOD SIMMERING TIME HAYBOX TIME
White Rice 5 min 1-2 hours
Brown Rice 10-15 min 2 hours
Potatoes (whole white) 5-10 min 1-2 hours
Creamed Soups 2 min 1 hour
Dried Beans (soaked) 10-15 min 3-4 hours
Meat Roast 20-30 min 3-5 hours

Earthen Solar Cookers

The Earthen Solar Cooker is a low cost and low environmental impact design envisioned by Bart Orlando [1] for use by the poor in refugee camps and in villages of non-industrialized nations. The design is simple; a large parabolicly shaped hole in the ground lined with reflective materials such as salvaged pieces of broken glass mirror or reflective can lids.
