While NASA has made a name for itself by exploring the potentials of life outside our planet, its new Sustainability Base building embraces and respects Earth’s natural resources. Officially deemed, ‘The Greenest Federal Building’, the new eco-structure was awarded the U.S. Green Building Council’s Leadership in Energy and Environmental Design’s (LEED) prestigious Platinum status, which is the highest possible rating awarded by the rigorous program.

The 50,000 square foot, two story office building cost NASA approximately $25 million dollars to build, and integrates natural sunlight into the employee’s working environment through the use of skylights and open windows. Building controls react to slight fluctuations in weather, light, and occupancy, which enables the building to regulate its energy consumption based on immediate need rather than blanket approximations.

Another revolutionary aspect of the building is that it does not have air conditioning. Instead, the building design incorporated air vents in the flooring, which captures the cool night air, and distributing it during the day.

The building is so efficient, it actually generates more electricity than it consumes, due in large part to onsite solar panels, fuel cells and a small wind turbine. The building also incorporates geo-thermo well field water, which circulates through the building through ceiling coils in order to heat or cool the building.

Very limited material was needed during construction due to a lightweight insulated metal panel cladding, and the infrastructure was made of steel instead of concrete because of steel’s flexibility in rebuilding -- should damage from a natural disaster occur.

NASA also incorporated some of its own technologies into the building, including a Bloom Energy Box fuel cell, and a duplicate of the International Space Station’s water recovery system.

While the building is visually stunning, it is also a monument honoring the future potential of green buildings. It proves that engineering is the key to gleaning the most bang for our resource buck, and with NASA leading the way, the future of sustainability is looking greener than ever.

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.
