Cement Returns to Its Sustainable Roots

cement green sustainable bricks
Chemists bring one of the oldest materials in building history back to its green roots. 

Cement is one of the oldest building materials cooked up by humans, but it’s so misunderstood. It’s not what paves your cement sidewalk, that’s concrete.  And it’s not concrete, although cement is a main ingredient. Modern advances in production and ingredient mix are reinventing this “everywhere” substance as a sustainable champ. The material itself is fairly green but fails miserably in whole lifecycle assessment. Cement relies on fossil fuels for processing its raw materials. Resultant emissions mean that making basic cement causes about 5 percent of all manmade carbon dioxide.

Think of it as glue. The ancients discovered that finely ground lime or silicates, mixed with water, will react at ordinary temperatures to form a sludgy ooze with superior binding powers. Recent advances in chemical mix and production technologies are not only making concrete carbon-neutral, it’s actually achieving carbon-negativity.

Turn Disposable Water Bottle into Pencil Case: Upcycling Tutorial

pencil case plastic bottle tutorialNow that the kids are back at school, time to go green and continue the celebrations with this back-to-school tutorial. Parents will need to help with this one.

This time of year with kids returning to school, many go on shopping spree spending lots of money on branded notebooks, agendas, and bags.

But why not for a craft and green option for a pencil case?

I’m all for using a reusable personal water bottle filled with tap water, but there are still plenty disposable plastic bottles around, so here is the step by step tutorial how to upcycle it to a cool pencil case!

Crafting has many benefits, in this case not only you are making your own personalised creation – using a water bottle allows for additional benefit: it’s transparent so you can easily see what’s inside your case. See below for instructions.

Spencer Tunick and Israel’s Tent Protest Leader Team up For Dead Sea

Dead Sea, Spencer Tunick, social activism, environmental activism, IsraelRenowned nude photographer Spencer Tunick and Daphne Leef, the leader of last year’s tent protests in Tel Aviv, are teaming up to promote creative social activism in Israel. In support of Save our Sea, a grassroots organization that strives to raise awareness of the Dead Sea’s declining ecological health, the pair have organized an overnight gathering and early morning photo shoot (sorry, no nudity this time).

The event scheduled to take place overnight on Thursday September 14th will include an early morning drumming session near the Masada ruins and end with a panel moderated by environmental photographer Roie Galitz.

3,000 Year-Old Public Water Works Unearthed in Jerusalem

jerusalem water well city temple periodJerusalem’s water consumption during the First Temple period was not solely based on the output of a natural spring, but relied on public reservoirs.

A large rock-hewn water reservoir dating to the First Temple period was recently discovered in the archaeological excavations that are being conducted in Jerusalem. The excavation, during the course of which the reservoir was discovered, is part of an archaeological project to expose the entire drainage channel of Jerusalem dating to the Second Temple period.

The channel runs north along the City of David spur, from the Siloam Pool to a point beneath Robinson’s Arch. The route of the channel was fixed in the center of the main valley that extends from north to south the length of the ancient city, parallel to the Temple Mount.

Is Organic Food Really Healthier?

Is Organic Food Really Healthier?

organic squash imageA study from Stanford University, California, concludes that organic food is no more nutritious than conventional. But how correct is that?

A furor of debate is breaking over a statistical analysis of data on food. Over 200 studies on organic and conventionally raised produce, grains, eggs, milk, poultry and meat were collated by Stanford University’s Center for Health Policy and broken down for comparison. The research was published in the Annals of Internal Medicine this month and concludes that organic produce has little nutritional value over the conventionally raised. This isn’t the first such study Green Prophet has reported.

Some argue that soil conditions of the organic produce wasn’t accounted for in the studies. Depleted soil will yield poor produce, no matter if organically farmed, and the soil conditions of the tested produce is unknown.

But the greater weight of the pro-organic argument falls upon the undoubtedly higher levels of pesticides, hormones and antibiotic-resistant bacteria in conventional produce. Consumers say that they’re less concerned with nutrition than with avoiding those evils. Even in the Middle East there are enough health-conscious consumers to justify opening organic stores.

It Took 15 Years to Build This and That’s a Good Thing

Ne'ot Semadar, Kibbutz, green building, Negev Desert, Israel, Organic Agriculture, green architecture

Remember the good old days when it took decades to build major monuments? Historians estimate that 30 years passed before the back-breaking pyramids of Giza came to glory, for example, and more than a century after construction began in 1882, La Sagrada Familia in Barcelona is still not finished.

Although laborers might disagree, there’s something honest about the kind of construction that requires slow extraction, transportation and re-assembly of the earth’s materials – especially compared to our current obsession with erecting buildings as fast as possible. In China, a 15-story building was supposedly built in a record-breaking six days.

Fortunately, not all people are beguiled by speed. We recently visited the renowned Kibbutz Ne’ot Semadar and talked to one of its founders about their iconic, passively-cooled community arts center that took 15 long years to build. Step-by-step, a group of like-minded nature-lovers learned the skills necessary to construct a landmark, structurally-sound earth building in the heart of Israel’s Negev desert.

Australia Kills Nearly 400 Camels From the Sky

Australia, camels, culling, feral camels, camel milk, genetically-modified camelsCamels are a nomad’s best friend but a serious nuisance in Australia, where the environmental ministry recently culled nearly 400 of them en masse. Despite efforts from locals to raise awareness of the numerous benefits of camels, the government has long waged a campaign against feral camels that roam the country’s desert region.

The South Australian Environment Department killed the camels after a truck collided with seven animals on the Eyre highway linking southern and western Australia. The truck driver wasn’t injured in the crash, but Nick Secomb, Project manager of the South Australian Feral Camel Management Project, told local press that “the camels weren’t so lucky.”

Meanwhile in Dubai, camels are being genetically engineered to produce pharmaceutical proteins through their milk. This is the first time, according to our sources, that drugs produced by transgenic animals will be approved for use in humans.

Bureaucracy Slows Israel’s Solar Energy Progress

Israel’s research labs such as National Solar Energy Center,  Grand Technion Energy Program (GTEP) and companies such as Zenith Solar and Arava Power Systems are developing advanced solar energy technology which is nearly cost-competitive with fossil fuels.  Israel’s solar technology has been used in places as far away as Australia and China.   Combine this with the fact that about 60 percent of Israel is a desert averaging more than 9 hours of sunshine per day and Israel’s solar energy industry should have a bright future.  But as of 2011 Israel had only installed 190 Megawatts of peak photovoltaic power generation capacity.  This is about 3 photovoltaic watts per person.  This places Israel at the top of the MENA countries, well ahead of Turkey which only has 0.1 peak photovoltaic watts installed per capita.  But outside of MENA, 19 countries exceed Israel’s photovoltaic generating capacity.  This surprising list includes such cloudy northern places as Canada with twice and Germany with 60 times Israel’s per capita photovoltaic capacity.

Tea Extract from Pakistan May Help Treat Breast Cancer

cleavage tea pakistanA tea made from a plant found in Pakistan, India, Africa and parts of Europe may help treat breast cancer, study suggests.

Following our report on turmeric‘s benefits for natural breast health, science is finding more evidence for Mother Nature’s healing possibilities. According to ScienceDaily.com, “scientists at Aston University and Russells Hall Hospital have discovered that an extract from a common plant in Pakistan may help treat breast cancer.”

While more research is needed, according to the report, the results were free from the side effects such as hair loss associate with modern cancer treatments. The plant, called Fagonia cretica, is part of a family of plants that grow in arid, desert regions including Africa, the Mediterranean and Middle East regions.

World’s First Genetically-Modified Camels in Dubai to Produce Medicine

Dubai, Camel Reproduction Center, science, health, FDA, genetically-modified animals, camelsThe same research laboratory behind the world’s first cloned camel and a hybrid llama and camel called Cama has recently announced that they are genetically modifying camels in order to produce pharmaceutical proteins through their milk.

Dr. Nisar Wani from the Reproductive Biology Laboratory at the Camel Reproduction Center outside of Dubai says the project is designed to decrease the cost of life-saving medicines such as insulin, but the words genetically modified are likely to sound off an alarm – especially since no other first world country has approved drugs produced from transgenic animals.

Bahrain’s Artifical Reef a Success After 16 Weeks

artificial reef bahrain

Only eight percent of our oceans are “shallow seas” (shallower than 100 feet), but these wildly diverse ecosystems harbor most of the world’s marine life.  Egypt, Israel, and Jordan (all connected to the Red Sea) and the Gulf states stand to lose enormous tourism revenue if their natural reefs continue to be destroyed by coastal development. Last year, the Bahraini government commissioned ten artificial reefs to be built in their coastal waters using perforated reef balls and tall structures designed to look like Arab wind towers.  Slap on your virtual scuba gear and see what’s happening four months after the first reef was placed.

Saphonian Blade-less Wind Turbines Save Birds and Energy

cleantech, green design, Saphonian, Saphon Energy, wind energy, sail, TunisiaWhile solar advancements continue apace, wind energy technology has remained fairly stagnant over the years, making it in most cases less viable than fossil fuels or nuclear energy. It’s expensive, harmful to birds and bats, deeply inefficient and comes with a host of annoyances such as noise and vibration.

Responding to what they perceive as a massive gap in innovation, Saphon Energy from Tunisia has designed blade-less turbines that mimic the shape and function of sails. Because they don’t rotate, Saphonian turbines are harmless to wildlife, and completely eliminate aerodynamic and mechanical losses associated with conventional turbines. And they cost nearly half as much to produce!

Travelling Without Money to Istanbul’s Travel House

istanbul travel houseA place where you can stay for free in Istanbul, meet other travellers and exchange travel experiences?

The Serbia Travel Club made their crazy idea reality, and Istanbul’s Travel House was open for everyone.  I paid them an overnight visit in Istanbul and rediscovered how enriching travelling can be. This summer, Serbia Travel Club established a temporary base in Istanbul, called the Travel House. It is a rented apartment in the center of Istanbul, whose doors are open to all travellers, from July 1 to September 1st. Staying in the Travel House was free for everyone. The goal of the Travel House is to provide a global meeting point for travellers, and thus be a small step towards building a global travel culture.

Souk Jara is Amman’s Favorite Flea Market

souk jara flea market amman

People usually associate a flea market with old, dusty clothes and other “junk,” consider it a sort of yard sale collision.  In Amman, however, Souk Jara is deemed a flea market and is a far better cry than that notion. A sort of upscale summer flea market, Souk Jara lets guests feast their eyes on a plethora of new, unique, handmade items on display by local artists – but that is not to say that antiques are not sold, too.

There is no rummaging through piles to find what lies underneath, as in typical flea markets.  But it’s a give and take: tediously combing through the crowd is always necessary, as the wide outdoor aisle that splits the merchant kiosks into two rows is packed with people.

A Sustainable Postcard from Turkey: You’ll Wish You Were Here

turkey plantersThis Green Prophet tours Turkey and sees a mosaic of eco-sensibility.

Little Eid, a Muslim holiday, is a great time for a getaway. So I reeled in my family from disparate zip codes for a week spent touring someplace new.  Years back, plump thighs on my enormous babies tagged the kids as “turkey legs”.  It feels right that we meet up in Istanbul. Turkey seems so sustainable. Look past the blinding kaleidoscope of colors and textures, tiled surfaces, carpets, spices and foods and spot clever detailing that tips off intrinsic enviro-awareness.

Atatürk International Airport has quiet little features that scream sensitivity to energy consumption. Overhead lighting throughout the main terminal is operated only when natural daylight is insufficient.
