Not many cleantech start-ups can claim a 40 million dollar deal only a year and a half after founding. But WateRevive, which was selected as one of the most promising Israeli cleantech start-ups by Calcalist newspaper in 2012, and which is active in water purification through constructed wetland, just closed such a deal in China. The Company is also (more…)
Israel has earned a leadership status in the international water arena, but to stay at the forefront innovation must keep pushing forward. A joint project by Israel NewTech, the Neaman Institute and the Israeli Export Institute has been launched in order to map out the needs for new water technology innovations in the largest industries in the world. The preliminary results (more…)
Safe drinking water from thin air? That’s the claim of San Luis Obispo, California, based Atmospheric Water Systems (AWS), which offers a product line of air-filtering water systems under the brand Dewpointe. Founded more than a year and a half ago by Co-owner Stephen Krauss, Dewpointe systems takes a different approach to creating safe drinking water. Rather than filtering the water that comes through a pipe, Dewpointe filters the moisture out of the air to create drinking water. There are no water pipes attached to the machine. The rectangular device simply plugs into a wall.
I caught up with Mr. Krauss on the second day of this year’s West Coast Green event held at Fort Mason in San Francisco, California, and found out more about the Dewpointe system.
How does it work? Magic?
No, similar to a dehumidifier, Dewpointe pulls moisture out of the air; but unlike a dehumidifier, the goal of this device is to make that moisture drinkable. A series of filters take out 99.99% of the impurities and create clean drinking water. Impressive as this may sound, it also means that there must be moisture in the air for Dewpointe to operate effectively. Hence, all tropical or even moderate humidity environments in the United States such as coastal states, the south and mid-west work well. In desert environments or low moisture areas such as the south-western US, the Dewpointe will struggle.
Ben-Gurion University of the Negev has partnered with the University of Johannesburg and the University of California, Los Angeles to conduct scientific research into the fields of water purification and microalgal biotechnology, according to a press release last month.
“This is an international partnership that will benefit the peoples of South Africa, Israel and other countries around the world,” said BGU’s Vice President for External Affairs Prof. Amos Drory on occasion of the signing. Drory and Prof. Derek van der Merwe, Pro Vice-Chancellor at the University of Johannesburg, signed the research collaboration agreement in South Africa.
“The two universities will become involved in extremely important, evolutionary research that will mainly benefit third world countries throughout the world,” said Dr. Bertram Lubner, Vice-Chairman of BGU’s Board of Governors and president of the SA Associates of Ben-Gurion University (SAABGU).
Prof. Sammy Boussiba and Prof. Yoram Oren from Ben Gurion University’s Blaustein Institute for Desert Research will head up the projects in Israel working together with Prof. Bhekie Mamba, leading the South African research teams. They will be assisted by Prof. Eric Hoek, an expert in the fields of water purification and microalgal biotechnology at UCLA. (more…)
“No doubts remain. Climate change is real and the build-up of greenhouse gases in our atmosphere is increasingly at an alarming rate.” With these words, Rafael Quiroga, General Manager of Accion RSE, initiated the seminar “Corporate Strategic Management of Climate Change and Greenhouse Gas (GHG) Emissions.” This is not another “green business” seminar from a European or North American city, it took place here — in Santiago, Chile.
The event brought together speakers from the Chilean private sector that gave concrete examples of their companies’ climate change and GHG management initiatives. First, it showed how Essbio, a water purification company, has been dealing with the ever-prescient and escalating challenges of decreasing water reserves due to climate change. Second, it illustrated the emissions and energy reductions Xstrata Copper, a mining company, has committed to and the steps it has taken to minimize the release of contaminants in its industrial processes. Third, it explained what Natura cosmetics has done since 2007 to become a “carbon neutral” business by calculating all GHG emissions in the company’s supply chain, transportation, and production of its various cosmetics products, and purchasing the equivalent amount of CO2 tonnage in carbon credits on the international carbon markets.
