GaiaRecycle™ Systems

California-based company, GaiaRecycle™, is well-established as a world leader within the organic waste recycling industry. The company has developed innovative technologies for transforming food scraps and other organic waste into high-quality soil amendments. Over 40 registered patents have been applied to the systems, which range in size, and are reported to reduce waste volume and weight by up to 90 percent. The systems speed up the organic decomposition process. Drying, sterilizing and grinding of materials can be completed within eight to eleven hours. The systems are used in both industrial and commercial applications, such as for large food manufacturers and producers, and livestock processing plants, across more than eight countries around the world.

“GaiaRecycle leverages proven technology, coupled with the latest clean technology and business innovations from Silicon Valley,” explains Young Song, CEO of GaiaRecycle, LLC. “Diversion of food scraps currently requires a lengthy process for developing local ecosystems to create a source-separated program, and an infrastructure for hauling and composting that requires many third-party dependencies. With GaiaRecycle systems, it provides a fast track for businesses to rapidly rollout an onsite organic recycling program, turn waste into valuable resources, and enhance corporate sustainability towards zero-waste without dependence on third-party operators.”

Green Mountain Technologies

Green Mountain Technologies has created a product line of composting systems, the newest and most advanced of which is the Earth Bin. This unique system is an extension of the Earth Tub, utilizing the same auger technology, with a much larger capacity and more automated controls, which are ideal features for use in large institutions, such as universities. Additionally, the unique, new system’s plug-flow technology significantly increases the amount of composting that can be done on a given footprint.

Vance Calvez, Manager of Sales & Customer Service at Green Mountain Technologies explains, “These systems help organizations reduce waste by allowing them to do on-site composting of their unused food scraps and unwanted landscape materials, such as leaves, cut grass or weeds. This substantially reduces their trash bill and helps reduce their carbon footprint. Plus, it keeps valuable nutrients in our soils, where they belong, and out of our landfills and waterways.”

The product has six installations so far and has been well received by customers. Calvez says, “The systems have been very successful. We have happy customers, and high-quality compost.”

GeoLogic GPS System

The GPS Landfill System, developed by GeoLogic, includes GCS:Density software, which measures compactor position as well as views compaction information. The leading-edge technology utilizes deflection information for calculating waste density. Plus, operators can view a map on the system-screen that measures surface deflection in real-time. The system also allows for information-sharing between compactors, in addition to progress-monitoring from the main office.

Considered to be one of the industry’s most accurate measurement tools, the device is best known for its ability to increase waste density. A customer of the company conducted an internal study, which indicated that the GeoLogic GPS Landfill System increased in-place waste density by seven to 14 percent. Lead Operator, Ed Worrell says,"On average, I would estimate we saw an increase of about 300 to 400 pounds per cubic yard since we began using the GeoLogic GPS.”

Molecular Waste Technologies Inc (MWT) Patented Microwave Technology

This patented process, by MWT, was created based on the use of microwaves, which have the unique ability to break down molecular bonds in hydrocarbon chains to basic carbon. Through the process, landfill components can be condensed into a light-oil, similar to diesel. The only items unable to be reduced through the process include glass and metals.

According to MWT, “The balance of the entire waste stream can be processed and reduced to carbon and oil.” The system has a modular design, which can be adapted to any size. “The technology was designed to accomplish two important goals. First, it had to be environmentally clean, with almost zero emissions; second, it had to reduce everything in the waste stream—Municipal Solid Waste, like tires and plastics—in short, all organics. The MWT Technology has accomplished both of these,” says MWT.

Celtic Cement Technology

This UK-based business has invented a way to repurpose materials that are generally discarded into landfills. Celtic Cement Technology has developed an innovative, environmentally-friendly process for converting landfill waste into cement replacements. The patented technology, which has been evolving over the last ten years, manufactures flexible, high-performance, sustainable cement substitute.

The company performs extensive testing and analysis to determine which industrial by-products can be used as cement alternatives, with the lowest amount of greenhouse gas emissions, and using minimal energy consumption. According to Celtic Cement, “In order to maximize the use of industrial by-products in cement and concrete, an understanding of all the characteristics of each raw material is required. It is essential that each material is tested in accordance with current standards to establish the short-, medium- and long-term effects in concrete structures.”

Sakuu Corporation creates 3D printer for EV batteries

Sakuu is set to enable high-volume production of 3D printed solid-state batteries for electric vehicles as more investment ploughs into SSB production

Sakuu Corporation has announced a new industrial-grade 3D printer for e-mobility batteries which it claims will unlock the mainstream adoption of electric vehicles.

Offering an industrial scale ‘local’ battery production capability, Sakuu believes the technology will provide increased manufacturer and consumer confidence. Sakuu’s Alpha Platform for its initial hardware offering will be available in Q4.

Backed by Japanese automotive parts supplier to major OEMs, Musashi Seimitsu, Sakuu is set to enable fast and high-volume production of 3D printed solid-state batteries (SSBs) that, compared with lithium-ion batteries, have the same capacity yet are half the size and almost a third lighter.

The company’s KeraCel-branded SSBs will also use around 30%-50% fewer materials – which can be sourced locally – to achieve the same energy levels as lithium-ion options, significantly reducing production costs. Sakuu anticipates the 3D printer’s attributes being easily transferable to a host of different applications in other industry sectors.

"For the e-mobility markets specifically, we believe this to be a landmark achievement, and one that could transform consumer adoption of electric vehicles,” said Robert Bagheri, Founder, CEO and chairman, Sakuu Corporation. “SSBs are a holy grail technology, but they are both very difficult and expensive to make. By harnessing the flexibility and efficiency-enhancing capabilities of our unique and scalable AM process, we’re enabling battery manufacturers and EV companies to overcome these fundamental pain points."

The ability to provide on-demand, localised production will create more efficient manufacturing operations and shorter supply chains, he added.

Sakuu will initially focus on the two-, three- and smaller four-wheel electric vehicle market for whom the company’s SSB proposition delivers an obvious and desirable combination of small form factor, low weight and improved capacity benefits. The agility of Sakuu’s AM process also means that customers can easily switch production to different battery types and sizes, as necessary, for example to achieve double the energy in the same space or the same energy in half the space.

Beyond energy storage, Sakuu’s development of print capability opens complex end device markets previously closed off to current 3D printing platforms. These include active components like sensors and electric motors for aerospace and automotive; power banks and heatsinks for consumer electronics; PH, temperature and pressure sensors within IoT; and pathogen detectors and microfluidic devices for medical, to name a few.

"As a cheaper, faster, local, customisable and more sustainable method of producing SSBs – which as a product deliver much higher performance attributes than currently available alternatives – the potential of our new platform offers tremendous opportunities to users within energy, as well as a multitude of other markets," said Bagheri.

Ongoing research and new funding collaborations

Omega Seiki, a part of Anglian Omega Group of companies, has partnered with New York-based company C4V to introduce SSBs for EVs and the renewable sector in India. As part of an MoU, the two companies are also looking at the manufacturing of SSBs in the country, according to reports.

Solid Power, which produces solid-state batteries for electric vehicles, recently announced a $130 million Series B investment round led by the BMW Group, Ford Motor Company and Volta Energy Technologies. Ford and the BMW Group have also expanded existing joint development agreements with Solid Power to secure all solid-state batteries for future EVs. Solid Power plans to begin producing automotive-scale batteries on the company's pilot production line in early 2022.

"Solid-state battery technology is important to the future of electric vehicles, and that's why we're investing directly," said Ted Miller, Ford's manager of Electrification Subsystems and Power Supply Research. "By simplifying the design of solid-state versus lithium-ion batteries, we'll be able to increase vehicle range, improve interior space and cargo volume, deliver lower costs and better value for customers and more efficiently integrate this kind of solid-state battery cell technology into existing lithium-ion cell production processes."

A subsidiary of Vingroup, Vietnam’s largest private company, Vinfast has signed an MoU with SSB manufacturer ProLogium - which picked up a bronze award at the recent Edison Awards - to accelerate commercialisation of batteries for EVs (click here).

Xin Li, Associate Professor of Materials Science, Harvard John A. Paulson School of Engineering and Applied Sciences, is designing an SSB for ultra-high performance EV applications. The ultimate goal is to design a battery "that outperforms internal combustion engines so electrical vehicles accelerate the transition from fossil-fuel-based energy to renewable energy," according to The Harvard Gazette.

The dramatic increase in EV numbers means that the potential battery market is huge. McKinsey projects that by 2040 battery demand from EVs produced in Europe will reach a total of 1,200GWh per year, which is enough for 80 gigafactories with an average capacity of 15GWh per year.
