The plug and play units will remove ions from industrial waste water by using the power of electricity (electrodialysis technology) and ultrasound as pre-treatment, with low pressure and energy, without using chemicals or high pressure osmosis.
It is supported by automatic regeneration of ions and self-cleaning filters and included with online water quality monitoring and telemetric control system.

Aquion did come up with a breakthrough saltwater battery. It is environmentally friendly, cost effective and has a life cycle way beyond any other battery: up to 5,000 cycles.
The development of sustainable saltwater batteries enters the next level.
The American company Aquion Energy has received $ 33 million extra finance.
Previously, Bill Gates invested in Aquion Energy.
Saltwater conductor
Aquion developed batteries that can store solar and wind energy to serve as backup for times when there is no wind nor sun. Saltwater batteries are not new, but the batteries from Aquion are special because they are using salt water as a conductor, instead of acids or bases.
Aquion has come up with a clever twist on a 200 year old salt water battery technology using:
Activated carbon (anode)
Manganese oxide (cathode)
And basically a salt water electrolyte
They have come up with a breakthrough solution. It is environmentally friendly, cost effective and has a life cycle way beyond any other battery: up to 5,000 cycles
So what’s Aquion’s energy storage innovation?
The startup — which was backed by Bill Gates and VCs like Kleiner Perkins and Foundation Capital — is making a low cost, modular grid battery made from basic materials like sodium and water.
The battery pairs a carbon anode with a sodium-based cathode, and a water-based electrolyte shuttles ions between the two electrodes during charging and discharging.
The technology was developed out of Carnegie Mellon University by founder and chief technology officer Jay Whitacre.
By using basic materials, Aquion is hoping its product is inexpensive enough to disrupt the current grid battery market.
Aquion’s CEO Scott Pearson:
“When the battery has been manufactured at a commercial scale for awhile, the price point of the battery could be $300 per kilowatt hour. That’s about a third of the cost of some of the more expensive lithium ion battery grid products.”
Advantages
Saltwater batteries are tolerant to wide temperature ranges, partial state of charge cycling, and daily deep cycling with minimal degradation.
In addition to the safety and sustainability advantages of using water as electrolyte, another advantage is the thermal mass of the embodied water means that Aquion products neither heat nor cool rapidly. As such, the products can operate in a very wide operating temperature window because they simply take so long to heat and to cool.
The saltwater battery chemistry relies on charge/discharge mechanisms which are unaffected by partial state of charge – these batteries can sit indefinitely at partial, or even no state of charge, without irreversible capacity loss like lead acid batteries.
In June 2016, Aquion Energy has introduced the Aspen 24S, a 24-volt version of its award-winning Aqueous Hybrid Ion (AHI) battery.
The new product is designed for energy-intensive applications that use solar panels, such as off-grid solar-powered LED lighting, as well as small pumps and motors. It is also an ideal drop-in replacement for existing systems using 24-volt lead-acid batteries.
The shipping sector needs a robust and ambitious action plan in order to decrease the emissions in the sector.
Ships are responsible for more than 5.5% of the global emissions!
That’s why the Sustainable Shipping Initiative (SSI) wants the International Maritime Organisation (IMO) quickly to make firm commitments to significantly reduce CO2 emissions from shipping. Read More

The rubbish bin, designed to float in marinas, inland waterways, residential lakes and harbors, catches floating debris and liquids by sucking water from the surface and letting if flow out through the bottom of the structure, trapping waste in a catch bag.
Do you love your boat? And do you want to clean up the water in the harbor? This is what we have for you. This genius bucket can suck garbage right out of the ocean.
It’s called the SeaBin and it works just like a fish tank filter. Let’s get rid of the plastic soup. Read More
“We have got a very good year,” according to IKEA Group President and CEO Peter Agnefjäll at the presentation of the Annual Review and Sustainability Report of the past year. “As a result we have been able to continue significant investments in sustainability, improving our product portfolio and more increasing the number of our stores.”
An atlas of pollution: the world in carbon dioxide emissions
The final declaration of the G20 summit in Antalya (Turkey) seems to be not an great start for the next climate summit in Paris. Especially India and Saudi Arabia will not cooperate. To limit the rise in global temperature to below two degrees Celsius, all countries must reduce greenhouse gas emissions.
Even after twenty hours of negotiations, both countries refused to agree a passage which included periodic monitoring of the reduction of greenhouse gas emissions.
The approach of circular economy is: make – use – maintain/ reuse/ remanufacture/ recycle. Waste should be seen as source of valuable resources. Products should be repaired, remanufactured and reused. A genius idea in times when resources get scarce – be it oil, water or different metals and when the world has to face a growing population. It is estimated that 9.2 billion people will live on earth in 2050 (UN).
The world in 2050: That world is a fair, high-tech and sustainable one – with advances that mean food for all, a reformed capitalism, and a circular economy.
But the road getting there will not be easy.
The more I look at the two sides – the environment and the economy – the more convinced I become that the way forward is to fully integrate resource efficiency into the way we live and do business in the world.
We know why a circular economy is a good idea. At the moment the world is still locked into a linear production chain that is resource intensive. We obtain resources and then discard them as waste.
The integrated electronics are easily to connect the solar hot water systems with panels that only supply electricity. Alius offers both variants.
The Dutch solar panels supplier AliusEnergy presented a solar panel that generates electricity as well as renewable heat. Smart inverters optimize the yield.
AliusEnergy supplies solar panels that will produce within the same module, both solar and renewable power. The pipes, used in the solar panel, have a module of 14 liters. Read More

He can heat his jacuzzi without receiving an utility bill with the extra energy he is generating. This is comfort!
Jan van Liempt, director of In2Ecobuildings:
“The electronics industry makes perfect stuff for consumers: TVs, iPhones, sound equipment. Everything is made because customers want it. Clients get value for their money.
Any complains? Most of the times, it’s resolved perfectly. Why not for houses? Nor installations? That’s my passion. I build energy neutral buildings and I have learned that comfort in an energy neutral building is possible!”
The idea is simple: create a car-free street for two months and let the people decide what to do with the space
For a period of two months, 25 streets in Ghent (Belgium) are transformed to the perfect play ground for kids.
The streets are closed to traffic.
The asphalt is covered with a green carpet. Neighbors made scattered tables and benches with wooden pallets. Street Live is returning, and even the opponents are turning – slowly.
Nowadays the traffic is too dangerous and parents are too afraid to let the children play outside.
In this Living Street, kids can play outside again.
Biomass power plants—in some cases, biorefineries—work much like a fossil fuel power plant. A plant-based product, such as wood scraps, trees, switchgrass, corn stover, hemp, sugarcane, corn, yard clippings or even garbage, is combusted to heat water into steam. That steam spins an electric turbine and electricity is created.
Six EU-countries have developed a calculation tool for suppliers of renewable energy from biomass.
The tool allows them to create an insight of the emission-savings if electricity and heat are conversed from biomass. Read More
