For the first time in seven years vehicle sales have risen to more than 16 million and automakers are capitalizing on the market upswing by offering customers a wide range of options from electric, to natural gas to traditional gasoline powered vehicles. On Tuesday at greenercars.org, the American Council for an Energy-Efficient Economy (ACEEE) released its 17th annual comprehensive environmental ratings for vehicles.

This year, the Smart ForTwo Electric Drive tops the "Greenest" list with a highest-ever score of 59 out of 100, just in time for the vehicle's nationwide rollout. Following closely behind are the Toyota Prius C and the Nissan Leaf with scores of 57 and 55 respectively.

Toyota's entire family of Priuses performs exceedingly well again this year, with the regular Prius and the Prius plug-in hybrid nabbing spots No. 4 and No. 7. Other top scorers for 2014 include the Honda Civic Hybrid (No. 5), Lexus CT 200H (No. 6), Honda Insight (No. 10), and the Volkswagen Jetta Hybrid (No. 12). Making its return to the "Greenest" list after an absence last year is the Honda Civic Natural Gas vehicle (No. 9).

New to the list this year is the Mitsubishi Mirage, Mitsubishi's new subcompact offering for the U.S. market. With a Green Score of 55, the gasoline vehicle takes the 8th spot on the list. The only other non-hybrid gasoline model to make the list this year is the Smart ForTwo, which placed at No. 11.

“We've had such an influx of hybrid and electric vehicles in recent years that the race to earn a spot on the ‘Greenest’ list is more competitive than ever, particularly for conventional vehicles. It's encouraging to see automakers investing heavily in eco-savvy vehicles on the whole,” said ACEEE lead vehicle analyst Shruti Vaidyanathan.

The greenercars.org website also identifies top widely-available models in each vehicle class. This "Greener Choices" list includes trucks and SUVs such as the Buick Encore, Nissan Rogue, and the Ram 1500 HFE. The Chevrolet Spark and Nissan Juke top their respective car classes. As the list demonstrates, consumers can make "greener choices" whatever their vehicle needs may be. Domestic manufacturers claimed four of the 12 “Greener Choices” spots.

 “From the rise in the number of efficient vehicles in car-sharing and car rental fleets to the myriad advanced technology vehicle choices available to consumers, the leading edge of the U.S. auto market is evolving rapidly,” said Steve Nadel, ACEEE's executive director.

 The site assigns each vehicle a “Green Score,” a singular measure that incorporates lifecycle greenhouse gas and criteria pollutant emissions. This year, a number of updates were made to the greenercars.org methodology to more accurately estimate vehicles' environmental impacts. These include updates to in-use emissions of methane and nitrous oxides, evaporative emissions estimates, and gasoline, diesel, and natural gas "upstream" emissions. Vehicles not intended to achieve significant sales volumes are not eligible for spots on the “Greenest” list.

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.
