Corporate Knights, the magazine for clean capitalism, recently announced its Greenest U.S. Presidents ranking just seven weeks before Americans head to the polls to select their next commander-in-chief. The results of the ranking, the first to be determined by top environmentalists themselves, show that protection of our natural world has a long tradition with both Democrats and Republicans.

Indeed, Republican presidents captured the two top spots in the ranking, followed by two Democrats. Of the 12 environmental groups surveyed, America's 26th President Theodore "Teddy" Roosevelt was overwhelming selected as the greenest president in history for making conservation of the country's natural resources a cornerstone of his policy. Richard Nixon, America's 37th president, who was responsible for creating the Environmental Protection Agency and signing several seminal pieces of environmental legislation into law, ranked second.

"Conservative environmentalist is not an oxymoron," said Theodore Roosevelt IV, a managing director at Barclays Capital and the great-grandson of Teddy Roosevelt. "The records of my great grandfather and Richard Nixon show the GOP is also the 'Green Old Party.' Reconnecting with these roots is crucial, not only to honor our covenant with future generations, but for our relevance as a political force."

"Every single person on the planet depends on nature – the environment – for their survival and prosperity," said Mark Tercek, CEO of The Nature Conservancy. "As the Greenest Presidents list attests, we have a strong tradition in America of bi-partisan support for conservation issues. We should be able today to find ample common ground on issues so fundamental to our own well-being."

Twelve individuals led their respective group's participation in the survey: Frances Beinecke, president of the Natural Resources Defense Council; Phil Radford, executive director of Greenpeace USA; Michael Brune, executive director of the Sierra Club; Carter Roberts, CEO of WWF-US; Mark Tercek, CEO of The Nature Conservancy; Robert Engelman, president of the Worldwatch Institute; Erich Pica, president of Friends of Earth; Kevin Knobloch, president of the Union of Concerned Scientists; Van Jones, president of Rebuild the Dream; Bill McKibben, founder of; Joe Romm, publisher of Climate Progress; and Ralph Nader, founder of Public Citizen.

"Determining the greenest president is a tricky exercise," said Tyler Hamilton, editor-in-chief of Corporate Knights. "Does one give credit to intentions, actions or successes? Jimmy Carter, for example, may have had the best intentions but his successes were more limited compared to Richard Nixon, who by all accounts didn't have a green bone in his body but was politically motivated to get the job done."

Corporate Knights asked top environmentalists to make the judgment call. The result is a first-of-its-kind survey that shines a light on a bi-partisan environmental tradition in the White House that is often forgotten. The ranking and an accompanying feature story can be found in the latest issue of Corporate Knights, distributed today through the Washington Post and available for download on iTunes via the App Store. Results, including each judge's selections and a background research document, can also be found at

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.
