Automotive giant Chevrolet is investing up to $40 million in carbon reduction projects across the country over the next few years. Thus far, the company is at 23,000 metric tons of carbon reduction, but the ultimate goal is up to 8,000,000 metric tons, or the equivalent of the carbon dioxide emissions that will come from the vehicles it plans to sell through the next year.

All based in the US, the projects will focus on energy efficiency (weatherization and building retrofits), renewable energy and planting trees. In Maine, Chevy is working with the Maine State Housing Authority in a carbon reduction program that will include the weatherization of 5,500 low-income homes over the next 5 years. To spread awareness, the company also promises to plant a tree for every person who plants a “virtual tree” on its Facebook page.

“Reducing carbon dioxide emissions is one of mankind’s greatest responsibilities,” said Dr. Michio Kaku, theoretical physicist, futurist, and presenter of the Carbon Stories web video series. “Creative carbon stories – like turning harmful emissions into energy – are everywhere.”

According to recent reports, Chevy will be working on a total of 16 similar projects across the country. Some of the contracts include replacing natural gas with renewable biomass in greenhouses, installing wind turbines for rural farmers, waste heat recovery at gas pipeline pumping stations and reforestation.

“We’ve chosen projects we believe will make a lasting difference in communities across the country. Progress is already underway, and we estimate it will take up to five years to achieve our initial goal. There’s still a lot of work to be done, but every project is a step in the right direction.” – Chevrolet

Investing millions in energy efficiency projects is always a good thing, but for a major automaker to launch a highly commercialized project, it's clear to be an act of saving face. GM recently launched its first fully electric car in over ten years with hopes that it will topple the popularity of the Nissan LEAF. After failing to hit its target sales of the Chevy Volt, the company is clambering to gain back its image of being a sustainable innovator.

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.
