The heat wave gripping the country is bad—more so than ever before.

The first five months of 2012 have been the hottest on record in the U.S. In June, 164 all-time high temperature records were broken around the country, compared to 47 all-time high records broken last June. Winter this year was also the driest and hottest its ever been in the western US since records have been kept.

According to the National Weather Service, that heat doesn't appear to be dissipating anytime soon. The summer will continue to see unusually high temperatures across the country.

So is this what climate change looks like? Well, since there's been a significant increase in these types of events over time, yes.

"An increasing frequency of heat waves —that's one aspect of climate change you can point to," National Weather Service meteorologist Greg Carbin told the Huffington Post.

In recent years, daily record high temperatures outpace daily record lows 2-to-1, according to Climate Central. That number would be expected to be even if the planet wasn't warming. Alarmingly, there have been over 40,000 high temperature records set or tied, compared to nearly 6,000 cold records this year alone, a ratio of around 7-to-1.

Learning to live more sustainability is becoming especially critical now as even the richest of nations gets a hard hit from the planet's killer heat. For those of us suffering through it with minimal or no air conditioning, here are a few tips for staying cool through summer:

  • Close your blinds during the day to block out excess heat.

  • Open the windows at night to let the hot air of the day out. Just make sure to close them again by sunrise as early as 5 or 6 in the morning.

  • Insulate your home (there may be government grants available to help offset this kind of upgrade).

  • Use light-colored roofing if you have a choice to reflect sunlight rather than absorb it.

  • Install attic vents.

  • Build a summer porch on the north side of your house where you can reflect on how to start reducing your carbon footprint.

Itronics successfully tests manganese recovery process

Itronics - a Nevada-based emerging cleantech materials growth company that manufacturers fertilisers and produces silver - has successfully tested two proprietary processes that recover manganese, with one process recovering manganese, potassium and zinc from paste produced by processing non-rechargeable alkaline batteries. The second recovers manganese via the company’s Rock Kleen Technology.

Manganese, one of the four most important industrial metals and widely used by the steel industry, has been designated by the US Federal Government as a "critical mineral." It is a major component of non-rechargeable alkaline batteries, one of the largest battery categories sold globally.

The use of manganese in EV batteries is increasing as EV battery technology is shifting to use of more nickel and manganese in battery formulations. But according to the US Department of Interior, there is no mine production of manganese in the United States. As such, Itronics is using its Rock Kleen Technology to test metal recoverability from mine tailings obtained from a former silver mine in western Nevada that has a high manganese content. 

In a statement, Itronics says that its Rock Kleen process recovers silver, manganese, zinc, copper, lead and nickel. The company says that it has calculated – based on laboratory test results – that if a Rock Kleen tailings process is put into commercial production, the former mine site would become the only primary manganese producer in the United States.

Itronics adds that it has also tested non-rechargeable alkaline battery paste recovered by a large domestic battery recycling company to determine if it could use one of its hydrometallurgical processes to solubilize the manganese, potassium, and zinc contained in the paste. This testing was successful, and Itronics was able to produce material useable in two of its fertilisers, it says.

"We believe that the chemistry of the two recovery processes would lend itself to electrochemical recovery of the manganese, zinc, and other metals. At this time electrochemical recovery has been tested for zinc and copper,” says Dr John Whitney, Itronics president. 

“Itronics has been reviewing procedures for electrochemical recovery of manganese and plans to move this technology forward when it is appropriate to do so and has acquired electro-winning equipment needed to do that.

"Because of the two described proprietary technologies, Itronics is positioned to become a domestic manganese producer on a large scale to satisfy domestic demand. The actual manganese products have not yet been defined, except for use in the Company's GOLD'n GRO Multi-Nutrient Fertilisers. However, the Company believes that it will be able to produce chemical manganese products as well as electrochemical products," he adds.

Itronics’ research and development plant is located in Reno, about 40 miles west of the Tesla giga-factory. Its planned cleantech materials campus, which will be located approximately 40 miles south of the Tesla factory, would be the location where the manganese products would be produced.

Panasonic is operating one of the world's largest EV battery factories at the Tesla location. However, Tesla and other companies have announced that EV battery technology is shifting to use of nickel-manganese batteries. Itronics is positioned and located to become a Nevada-0based supplier of manganese products for battery manufacturing as its manganese recovery technologies are advanced, the company states.

A long-term objective for Itronics is to become a leading producer of high purity metals, including the U.S. critical metals manganese and tin, using the Company's breakthrough hydrometallurgy, pyrometallurgy, and electrochemical technologies. ‘Additionally, Itronics is strategically positioned with its portfolio of "Zero Waste Energy Saving Technologies" to help solve the recently declared emergency need for domestic production of Critical Minerals from materials located at mine sites,’ the statement continues.

The Company's growth forecast centers upon its 10-year business plan designed to integrate its Zero Waste Energy Saving Technologies and to grow annual sales from $2 million in 2019, to $113 million in 2025.
