D.C. building earns three Green Globes
The Green Building Initiative has awarded its second-highest rating of three Green Globes to the new Washington, D.C. headquarters of the American Forest Foundation for its environmentally-focused design and construction.
A nonprofit, AFF tapped the Green Globes program to guide and assess its new office project in seven standard categories: energy, water, materials and resources, emissions, indoor environment, site and project management. To guide the assessment, GBI furnished an independent, on-site, third-party assessment to help determine that AFF had earned three Green Globes out of a possible four using the Green Globes for New Construction tool.
The 11,000-square-foot space makes considerable use of wood certified through the Sustainable Forestry Initiative, one of four North American forest certification standards supported by Green Globes. As the offices were constructed within the confines of the existing office building at 2000 M Street NW, AFF was able to re-use many elements that might otherwise have gone to a landfill.

“We're delighted that AFF used Green Globes to guide and evaluate this new office and that AFF and its design and construction team were committed to achieving a strong rating,” said Jerry Yudelson, GBI president. “After all, their mission—to protect our forest heritage—is completely in alignment with GBI's commitment to sustainable buildings and reducing the carbon footprint of the built environment.”
In addition to using Green Globes, the team applied strategies from AFF's environmental education program Project Learning Tree to ensure energy efficiency. Light-harvesting technology limits electrical usage, and nearly everything in the office incorporates at least some recycled materials – from the furniture upholstery to kitchen countertops. Carpeting was installed using less adhesive to reduce the amount of volatile organic compounds (VOCs) emitted into the air, and low-VOC paints and varnishes were selected. The wood fibers in the ceiling panels are made of a material called Tectum, made from Wisconsin-grown aspen trees.
“It's a home for everyone who cares for forests,” said AFF CEO and President Tom Martin. “We're very proud of the way the office represents the mission and values of the American Forest Foundation, and of the recognition from Green Globes.”

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.
