Wouldn’t it be nice if this pesky little “climate change” talk would just disappear into the oblivion and we never had to worry about being responsible with our planetary resources ever again? Yeah, me too. Unfortunately, all signs point to us destroying our planet through carbon pollution and, our little piece of Eden and its atmosphere are starting to really heat up. Literally.

As we now know, as the population rises, so do the carbon emissions; as the amount of carbon pollutions rise, so does the heat index; when the heat index rises, so do our energy bills. That’s a fun little cycle, isn’t it? I suppose those of you with endless finances that live in cooler climates wouldn’t mind such changes to the environment but there are a few billion of us that find this trend extremely precarious.

Did you know that excessive heat is the number one weather-related killer in America? It beats out deaths from all other weather-related incidents combined. The elderly and children are at a higher risk during those deplorable summer months, as are people with kidney and cardiovascular diseases, but as temperatures reach record highs year after year, we all become at risk.

Heat Wave and Energy

We all know that summer is peak time for our energy needs. The kids are home for the summer, they insist on watching television, playing video games, leaving the doors to the refrigerator open, charging their iPhones, iPads, iPods and whatever other iProducts they can get their hands on, and the air conditioning and every light in the house stays on throughout the day.

Not only does this increase your electric bill, but the combined usage in your state severely saps the electrical grid. This could mean that if we don’t start conserving power now, our supply of electricity could fall short when we need it most to survive those scorching summer days. So what are we going to do?

It Starts With You and Me

If we want to live and thrive on a sustainable planet, we need to start making some small changes. Here are a few ways to beat the heat this summer and help slow the process of global warming:

  • Keep your thermostat to a reasonable level, set it on a timer when you’re not home, or turn it off. If slowing global warming isn’t enough of an incentive, as an added bonus, you can save anywhere from five to fifteen percent on your electricity bill for every ten degrees that you raise your thermostat during the month.

  • Install and use ceiling fans instead of air conditioning.

  • Unplug everything in your house, when not in use, or invest in a smart power strip.

  • Use energy efficient light bulbs and make sure they’re cleaned regularly. Dust on a light bulb produces more heat.

  • Plant trees. If strategically placed, they provide shade in the summer and block the wind in the winter.

Remember, if you want to change things, the power is always in your hands.

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.
