Since the early 1990s, the Energy Star certification program has made consumer electronics and appliances more energy efficient, and the Energy Star logo has become internationally recognized as the symbol of an eco-savvy consumer.  Originally implemented by the U.S. Environmental Protection Agency (EPA) and Department of Energy (DOE), the program quickly gained ground in Australia, Canada, Japan, New Zealand, Taiwan and the European Union.  Now the EPA is raising the bar on the energy star program, and implementing its highest ranking, simply called, “Most Efficient.”

In 2010 alone, the EPA and DOE calculated that American consumers saved $18 billion on energy bills by using Energy Star products. 

The new Most Efficient category for the Energy Star certification will apply to the top five percent of products in each given category according to a set of new criteria.  The first categories that will be part of the new ranking are clothes washers, heating and cooling appliances, furnaces, televisions and refrigerator-freezers.

“This new designation will help Americans save money and cut pollution by quickly pointing them to the best Energy Star products have to offer,” says EPA Administrator Lisa Jackson.  “Highlighting Energy Star’s Most Efficient products is a great way to encourage the strides in innovation that bring even more energy and money saving choices to our stores. We know American consumers are eager to make purchases that save them money on their utility bills and reduce the pollution in the air we breathe, and these labels will help them identify the best ways to find those purchases.”

Several companies have managed to obtain Most Efficient ratings early, including: Electrolux Major Appliances, Sears’ Kenmore, LG, Samsung, Best Buy’s Insignia Brand, Panasonic, Nordyne, and Rheem

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.
