The Environmentalist Family: Shlomit and Guy Valensi

Shlomit and Guy live in a small village in the lovely Hof HaCarmel region, one hour drive north from Tel Aviv and a 7 minutes walk from the beach. Shlomit practices Chinese traditional medicine, a field she has studied for many years. When she speaks you can hardly believe she used to be an aeronautics engineer working for the Israeli renowned Rafael Advanced Defense Systems. “My high school years instilled in me the green point of view. I studies in a unique environmental program in Sde Boker [in the Israeli Negev desert]. I was always aware to environmental issues, a
nd cared about them. After bringing my children into the world, I have decided to change tracks. To live closer to nature and closer to my children.”



HomeBiogas In. Composter and Gas Out.

“We used to have a composter, but recycling our kitchen waste with the HomeBiogas system is so much easier. It’s cleaner, you toss scraps in and forget about it. And the amazing thing is, that unlike the composter, it generates our cooking gas ”

Shlomit has a pet name for their HomeBiogas system: Tshuva. Tshuva in Hebrew means “Answer”. Tshuva is also the last name of the Israeli business magnate who owns the rights of the natural gas reserves located off the Israeli coast. “We pointedly call cur system Tshuva, because it is our own answer to energy needs” she says.

Shlomit and Guy discuss the problem of waste management and different energy alternatives with their children freely. Their son, Shahar who is 9 years old, is already very knowledgeable about the topics and happily explains the biogas generation process: “The bacteria digests the rubbish and makes methane. Because methane is lighter than air and water, it goes up to the gas tank above, and from the tank the gas flows into our stove.”

Vision for the Future

Shlomit says they aspire to build their new home using the most environmentally-sustainable methods available. The family is planning  to install solar panels on their roof, as well as a grey water recycling system.  They will expand their garden to include a wider variety of fruit trees and create a small edible forest. The fertilizer produced from the HomeBiogas system will help nourish the plants.

“My vision is to build a new house on our land, with the smallest carbon footprint possible.”
