San Diego Gas & Electric Named US Climate Leader
San Diego Gas & Electric(SDG&E) will be nationally recognized tonight with theSupply Chain Leadership Award at the second annualClimate Leadership Awards in Washington, D.C. The Climate Leadership Awards recognize organizations that go beyond business as usual in the management and reduction of greenhouse gas (GHG) emissions and are presented by theU.S. Environmental Protection Agency(EPA), theAssociation of Climate Change Officers(ACCO), theCenter for Climate and Energy Solutions(C2ES) andThe Climate Registry(TCR).
TheSupply Chain Leadership Award is being presented to SDG&E for being a leader with comprehensive GHG inventories, aggressive emissions reduction goals and leading edge management of GHGs in their supply chains.
"At SDG&E, environmental stewardship is a corporate value and an important part of our culture," said Pamela J. Fair, SDG&E vice president, environmental and operations support and chief environmental officer. "We have a holistic and comprehensive view on sustainability and proactively look at incorporating sustainable best practices in everything we do."
SDG&E is receiving the award tonight at theClimate Leadership Conference held in Washington D.C. The national awards program recognizes and encourages exemplary corporate, organizational, and individual leadership in reducing carbon pollution and addressing climate change. Last year, SDG&E was awarded theOrganizational Leadership Award for taking aggressive actions to reduce their carbon footprint.
"I commend SDG&E for leading by example with their outstanding actions to help reduce carbon pollution," said Gina McCarthy, assistant administrator for EPA's Office of Air and Radiation. "SDG&E and all our Climate Leadership Award winners are tackling the challenge of climate change with practical, common sense and cost-effective solutions to improve efficiency and cut waste."
Over the past year, SDG&E collaborated with key suppliers to develop innovative programs to reduce the company's environmental impact such as:
Designed more efficient, lower-carbon ways to build concrete vaults Installed more environmentally friendly utility poles Right-sized the lengths of electrical cable to reduce waste Recycled assets taken out of service and diverted 16 million pounds of materials from landfills Sourced certified "green" chemicals for janitorial services Increased use of recycled, rather than non-recycled, paper for required business needs and minimized paper usage with double-sided printing Launched a pilot Supplier Relationship Management program to track sustainability metrics with four key suppliers
"We are 'greening' our entire value chain - beginning with our suppliers - by challenging them to provide us with more sustainable solutions and greener products," said Fair. "We challenge ourselves and our employees to continuously pursue more sustainable ways to operate our business and to provide service to our customers. Finally, we work every day with all our customers to offer programs and information to help them save energy."
SDG&E continues to focus on achieving aggressive targets for renewable energy procurement, delivering innovative energy efficiency customer programs, and encouraging the use of alternate fueled vehicles, among other initiatives.
SDG&Eis a regulated public utility that provides safe and reliable energy service to 3.4 million consumers through 1.4 million electric meters and more than 860,000 natural gas meters in San Diego and southern Orange counties. The utility's area spans 4,100 square miles. SDG&E is committed to creating ways to help customers save energy and money every day. SDG&E is a subsidiary of Sempra Energy(NYSE: SRE), a Fortune 500 energy services holding company based in San Diego.

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.
