2012 Product Overview

Our Cookstoves

Our cookstoves are beautiully engineered to meet the environmental needs o our planet and

the desires o amilies around the world. Uniting combustion science and cutting edge product

design, we create highly ecient, clean burning cookstoves that are as durable as they are

beautiul. Envirot has helped more than 300,000 amilies breathe healthier air and spend less

time and money on uel. And the worlds orests breathe easier, too.

Our Lighting Products

We know how to create products that are at the center o indoor living. Beautiul products that

people want to own and care or engineered to last. Thats why weve created Envirot Lighting.

Durable. Aordable. Desirable.

Enviroft Quality Testing Services (EQTS)

Through years o hard work, Envirot has gained a deep understanding o what it takes to make

clean and ecient cookstoves and energy products. So we have created our own engineering

service business to assist household energy programs and projects around the world. We want to

share our knowledge with the world.

The Enviroft Way

We believe the right clean energy products put in the hands o people in emerging markets can

change the world. Those products must be aordable, durable and desirable. This can only be

done by combining advanced engineering, fexible manuacturing, and modern product design

strategies. Creation o local jobs and helping local entrepreneurs develop their businesses.

Thats what we do.

Rigorous Engineering & Testing

A clean, ecient cookstove is a simple idea. But designing

and producing hundreds o thousands o cookstoves thatare both durable and aordable is very complicated. It

requires the best science and technology on the planet.

Envirot and Oak Ridge National Laboratories worked

together to create a proprietary alloy which provides

the lowest cost, highest perorming and most durable

combustion chamber ever used in a clean cookstove.

Rigorous Engineering & Testing

We have developed new testing and modeling

techniques that allow us to develop products aster

to meet the changing needs o a diverse global

market place.
