These cookstoves use a lot of fuel, firewood, and produce a lot of smoke. Ester told us that cooking with this type of stove made her eyes turn red and she often had a chest cough. Her children, ages 5, 2 and 3 months are often with her when she is cooking. Her sister-in-law, Shadya Jumanne, age 11, helps her cook as well. Not long ago Ester’s 3 month-old developed a cough, It kept getting worse and so they took her by motorcycle to the hospital at night. Ester started really worrying about this. After this Ester and her husband agreed that they needed to buy a clean cookstove and started saving. The girl helping Ester cook in some of the images is her sister-in-law Shadya Jumanne, age 11. Ester met Solar Sister entrepreneur Fatma Mziray when she married her husband and moved to this village, Mforo near Moshi, Tanzania. Ester said that Fatma is like a mother to her in the village.

857-66658 - Seven workers are disassembling computers at TES-AMM Shanghai, which was founded on September 21, 2005, currently has 67 employees of which 26 are workers. With an annual production capacity of 10,000 tons, it has only treated 2,000 tons of e-waste from its founding more than a year ago. 'The biggest problem is that there isn't an e-waste recycling channel in China. The biggest chunks of raw materials we get are from government bodies, which are upgrading their equipments, and electronic appliances franchises that are washing out their outdated inventories. We don't have any imported e-waste because that's banned by the government. It takes a worker no more than ten minutes to disassemble a computer, and each worker can deal with between 60 to 70 computers a day,' says Janice Wu, who's the Environment & Quality Management Dept. Manager and Plant Manager Assistant.
