You don’t get much more elegant and luxurious than the Proximity Hotel in Greensboro, North Carolina, but add eco-friendly to the mix and you’ll sleep extra sound. The Proximity uses 36 percent less electricity and 30 percent less water than comparable luxury hotels and is LEED Platinum certified: the highest institutionalized standard of green building certification in America.

The 147-room hotel features custom designed furnishings, locally commissioned art, and various unique sustainable design aspects. North America’s first regenerative drive Gen2 elevator system has been installed at the Proximity hotel, which captures the elevator’s energy and feeds it back into the building’s electricity grid for added efficiency. There are 100 solar panels mounted on the roof to generate electricity to heat water. However, the building was specifically designed not to hinder the overall luxury of the hotel, and guests are none-the-wiser to the energy saving capabilities of the Proximity.

The hotel rooms themselves feature giant 50-square-foot windows to promote natural light. Room service and the hotel restaurant use local food to create traditional dishes as well as signature European bistro-style cuisine. The kitchen uses a sensor-controlled ventilation system and geothermal energy for refrigeration equipment. Dining tables are made from reclaimed walnut.

The reinforced steel used in the Proximity’s construction is made of 90 percent post-consumer recycled content. 75 percent of the hotel’s waste is recycled, and the walls and floors feature low-VOC paints, carpets and adhesives. The Proximity is even planning a green rooftop, featuring vegetation to reduce heat absorption in the building.

So if you find yourself in Greensboro, North Carolina and want to stay somewhere both luxurious and eco-friendly, be sure to visit the Proximity Hotel: the greenest hotel in America.

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.
