Audi announced today that it will team up with biofuel startup Joule to test and validate the alternative fuel for the auto industry.

Joule Unlimited, a Massachusetts biotechnology company, has developed a genetically-engineered organism that secretes diesel or ethanol under conditions of sunlight, water and carbon dioxide. It can be manipulated to produce renewable fuels on demand in mass quantities in facilities of any size and at costs that are competitive with the cheapest fossil fuels.

According to Joule, this could be a huge breakthrough in energy independence. “If we're half right, this revolutionizes the world's largest industry, which is the oil and gas industry. And if we're right, there's no reason why this technology can't change the world,” said Joule's chief executive Bill Sims.

Last week, the company commissioned a demonstration plant in New Mexico to display its radical approach to making ethanol from sunlight and CO2 on a fraction of the land used with traditional methods.

As of February, the potential of the company's production process was supported with the publication of a detailed analysis of its breakthrough platform. Published by Photosynthesis Research, the peer-reviewed article examines the company's advantages of producing renewable fuel and chemical production with yields up to 50 times greater than the maximum potential of any process requiring biomass.

"In contrast to research of the past, we have shown that photosynthesis is the superior platform technology for direct, renewable fuel production at the volumes and costs required to supplant fossil fuels," said Dan Robertson, PhD, co-author of the article and Senior Vice President of Biological Sciences at Joule. "The engineering of a photosynthetic microorganism to directly synthesize an infrastructure-compatible product, and continuously secrete that product, represents a landmark in industrial bioprocessing. The process technology is equally unique in that a highly-efficient, low-cost SolarConverter® system enables unprecedented productivity, as fully explained in our analysis and now being demonstrated at pilot scale."

The deal with Audi will serve as a huge point of interest in the market of carbon-neutral driving.

“Joule and the fuels it is developing can ultimately enable sustainable mobility, as its highly-efficient process consumes waste CO2 emissions, avoids depletion of natural resources and doesn’t require agricultural feedstock or arable land,” says Reiner Manglod, the head of environmental products at Audi in a statement.

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.
