The innovators: looped water system for Earth friendly shower

The innovators: looped water system for Earth friendly shower

When he was working on an academic project with Nasa, Mehrdad Mahdjoubi, a Swedish industrial designer, realised there could be parallels between sustainability in space and on Earth. The extremes of space required that the vital resource of water be used in the most efficient way possible. Water should also be used like this in the home, he thought.

Inspired by those experiences with the space agency, Mahdjoubi created a shower system that reuses the same water in a circular loop, while two filters take out impurities as it circulates.

This Shower of the Future , from his company, Orbital Systems, can operate on five litres of water. The water constantly circulates for 10 minutes or so – the time of an average shower – in turn saving also on energy.

“The reason that we make it work sustainably in space is because we have to do it,” the Swedish industrial designer said. “What if we try the same things on Earth … [if] the house was like a space capsule, how would we go about it? The most sustainable lifestyle is the one that we have in the most extreme environments and that may be in space or in a submarine where you actually have no choice but to really care for the resources that you have.”

Mahdjoubi said that while savings have been made in how water is used in toilets and washing machines, the same was not true of the shower. “Without changing the technology, we seem to just heat up water and put it down the drain,” he said. In Sweden, where the company is based, the average shower emits 15 litres of water a minute. During a 10-minute shower this amounts to 150 litres, he said.

The Orbital Systems shower starts with five litres of water and adds more if some is splashed out or is taken out of the system by the filters.

Water is first pumped through two filters, one which takes out larger particles such as sand, skin and dust and then a finer filter to extract bacteria, viruses and blood.

From there the water travels through a heater that moderates the temperature, which is set by a wheel control the user can change from hot to cold. The water then exits the shower nozzle as normal.

But when the water trickles through the drain it goes through a sensor which analyses it. If it is contaminated, the sensor recognises this and replaces the water.

The company says water flows at a rate of 20 litres a minute, compared to conventional showers, which typically range between seven and 12 litres a minute.

The shower takes in water from the mains until it senses that there is enough to go in a constant loop, said Mahdjoubi. “Even though the water is clean we would always flush it out before the next user. Comparing [it] to a hot tub where you sit in your own dirt for however many minutes, this is way more hygienic. When you stand in front of one of these showers you completely forget that the water is being recycled. It is the most unremarkable thing.”

The shower unit can be fitted as either an integrated system in the floor or as a standalone cabin with glass walls. The first units were delivered in December with most of the sales to commerical customers such as gyms, residential homes, swimming pools and the Swedish military. Nursing homes and hospitals have also bought them, said Mahdjoubi, because of the filter system.

“Not because they really want to save a lot of water but because you can guarantee that the water is clean and free from Legionnaires’ disease because it is always being filtered.”

How much money is saved depends on the cost of water and energy and how often the shower is used, he said. The company claims that a UK home can save £1,100 a year assuming there are four showers taken a day lasting nine minutes each.

Offsetting this is the price of the shower. The cheaper of the two residential units, where the shower is integrated into the floor of the bathroom, costs £3,300 while the standalone cabin costs £4,100.

As sales increase, Mahdjoubi said, the price would fall to less than £2,000 in three years. “I would say that we are steadily going down in price but we have to start where the market can afford it, that is why we have this premium and commercial focus we have right now,” he said.

A family would need to spend an average of about £110 every year replacing the purification capsules.

So far hundreds of the showers had been sold, said Mahdjoubi, and there had been particular interest from Denmark (location of one of the highest water prices in the EU) and from California, where there had been persistent droughts over recent years.

The Guardian view on COP 21 climate talks: saving the planet in a fracturing world

The Guardian view on COP 21 climate talks: saving the planet in a fracturing world

Powered by Guardian.co.ukThis article titled “The Guardian view on COP 21 climate talks: saving the planet in a fracturing world” was written by Editorial, for The Guardian on Sunday 13th December 2015 20.16 UTC

In the late 20th century, those who stood against globalisation were charged with swimming against an unstoppable tide, caricatured as “Stop the world, I wanna get off!” But in the 21st century, history is running with the anti-globalisers. World trade talks have gone nowhere, immigration controls have shot up the agenda, and two post-national EU projects – the euro and Schengen – are under strain. Figures as diverse as Donald Trump, Nicola Sturgeon and Marine Le Pen – who failed to convert a remarkable first-round victory in French regional elections into any outright wins – are all peddling one form of nationalism or another. Rumours of the death of the nation state, then, have proved exaggerated: globalisation is spinning into reverse.

Looking back on the future as it appeared in the 1990s – as a technocratic, transnational order – a democratic push-back was surely inevitable, in some senses even desirable. But when problems from the overuse of antibiotics to terrorism refuse to respect national borders, the retreat from the dream of global governance has some frightening consequences, especially in connection with climate change, the archetypal global problem. Saving the planet in a fracturing world is a daunting challenge indeed.

The Paris COP 21 talks surpassed expectations in rising to it, demonstrating just how much can be achieved by determined diplomacy, even while working within the unbending red lines of jealously sovereign states. A formal treaty was precluded because it would hand a veto to the intransigent legislators of Capitol Hill, while also offending the sensibilities of Delhi and Beijing. Fortunately, it proved possible to work within the fudged alternative framework of a “legally binding instrument”. Everyone offered up voluntary emission targets, and agreed, too, to a five-yearly review of these. While the targets on the table are not yet adequate to avoid the disaster of more than 2C of warming, the surprise inclusion of an aspiration to cap temperature rises at 1.5C signals a shared understanding that the targets will have to be tightened at each successive review. The destructive standoff between developing and developed countries that doomed Copenhagen six years ago has been transcended: the big developing economies, which now produce the bulk of emissions, are no longer pretending that they can delay doing anything until the rich world is perfectly green; at the same time the rich world is effectively accepting that it will have to help shoulder the “loss and damage” costs inflicted by the long legacy of western pollution.

This is, on the face of it, a rare and heartening case of disparate peoples being led to a common conclusion by evidence and reason, but serendipity played its part too. It happens, for example, that in 2015 there is a progressive US president who never has another election to win. It happens, too, that China is the midst of replacing filthy old power stations, which is already curbing its emissions growth, making it less painful than before for Beijing to engage. Indeed, the latest global CO2 data registers a striking levelling off, raising the tantalising possibility that technological progress could be entering a phase where the cast-iron link between emissions and growth begins to rust. If that pattern were borne out in future years, future climate negotiations could get smoother on every front. Then there is the great oil price crash, which facilitates a more fruitful discussion on fossil fuels, by making it much more imaginable to keep it in the ground.

One anxiety is whether this fortuitous alignment of political and economic stars will remain, as nations move from making promises, towards real action. Paris cannot guarantees success, but it does encourage hope – and particularly if Ms Le Pen’s chauvinist form of nationalism can be seen off. The Front National dabbled in greenwash last year, but its insistence on an ecology defined by “patriotism and the national interest”, and its instinctive suspicion of a multilateral UN approach is precisely the attitude which could thwart the translation of impressive COP 21 words into deeds.

Paris has given the world new hope in the possibilities of pragmatic diplomacy, at a time when France’s own politics illustrate the difficulties of assuming solidarity extends beyond national borders. If the answer to climate change is going to have to be found in continuous haggling between 200 nations, then success is also going to depend on winning the argument against narrow nationalism in every corner of the world.

Biofuel from trash could create green jobs bonanza, says report

Biofuel from trash could create green jobs bonanza, says report

Powered by Guardian.co.ukThis article titled “Biofuel from trash could create green jobs bonanza, says report” was written by Arthur Neslen in Brussels, for theguardian.com on Tuesday 17th February 2015 10.26 UTC

Creating biofuels from waste produced by industry, farms, and households could generate 36,000 jobs in the UK and save around 37m tonnes of oil use annually by 2030, according to a new report.

Across Europe, hundreds of thousands of new jobs could be created by using these ‘advanced biofuels’, which could replace 16% of the continent’s road transport fuel by the same year, the International Council on Clean Transportation (ICCT) study said. But the gains will not come without ambitious policy to promote advanced biofuels, it warned.

“Alternative fuels from wastes and residues offer real and substantial carbon savings, even when taking account of possible indirect emissions,” said Chris Malins who led the analysis for ICCT . “The resource is available, and the technology exists – the challenge now is for Europe to put a policy framework in place that allows rapid investment.”

However, a key vote in the European Parliament’s environment committee next week could stop this potential being realised, as a centre-right grouping of MEPs has signalled that it will oppose a biofuels reform package considered crucial to the fledgling industry.

The committee will vote next Tuesday on a compromise biofuels reform bill that would mandate a goal of advanced biofuels providing 1.25% of Europe’s transport fuel by 2020.

This advanced fuel could come from woody crops, agricultural residues, algae or household and industrial waste. It is seen as less environmentally damaging than first generation biofuels produced by growing crops such as rapeseed, which have been criticised for displacing food crops and raising commodity prices.

Malins said that a mandatory advanced biofuels goal was “absolutely crucial” to realising the sector’s potential, as it would bring market certainty and long-term signals for investors.

But sources at the centre-right European People’s Party (EPP) told the Guardian that they were unlikely to back such a package. “We think it is unrealistically ambitious,” a source said. “We are not going to support the compromise proposal.”

The bill would also introduce criteria for assessing biofuels’ sustainability and set a 6% cap for the amount that first generation biofuel could contribute to the EU’s 2020 target of providing 10% of road transport fuel from low carbon sources.

Marko Janhunen, the vice-president of UPM Biorefining in Finland, said that parliamentary manoeuvring could risk the advanced sector’s potential for hi-tech job creation in rural areas.

“This is a critical moment for the advanced biofuels sector and this discussion is very frustrating,” he told the Guardian. “We want to see incentives and reasons to invest. We want to get rid of the regulatory uncertainty that has been surrounding the discussion.”

UPM recently opened a €175m renewable waste biorefinery that transforms residues from pulp into renewable diesel that can be used by cars – or potentially, one day, by planes. British Airways is one of several members of a Leaders of Sustainable Biofuels group that Janhunen also chairs.

“The EU has spent hundreds of millions in projects supporting the uptake of these technologies,” Janhunen added. “Now they are here, it is very important to set policies in place that enable them to be brought into the market.”

The current proposal has faced a tortuous journey and campaigners fear that even a narrow victory now will embolden east European states to finally bury it in the European Council.

“If the EPP votes against the compromise, there is a massive risk that the whole package could fall into a conciliation process, or even no conclusion at all,” said Nusa Urbancic, a clean energy programme manager at the Transport and Environment group. “This will mean continued negative impacts on deforestation and food prices, as well as leading the EU away from our climate objectives.”

The European ethanol industry association (ePURE) has thrown its weight behind the biofuels bill. Its secretary-general, Robert Wright, told the Guardian that “only a binding target will send a clear signal to investors that there will be a future market for advanced biofuels.”

But other industry figures were sceptical about the likelihood of meaningful regulation at the EU level, and about the ICCT’s analysis more generally.

“Studies like this have rosy assumptions that feed into rosy conclusions,” said Eric Sievers, the CEO of Ethanol Europe Renewables. “You don’t make a large capital investment in a regulatory regime that expires in 2020, so the potential and reality are at odds. Nothing prevents this stuff from being imported from the US or Brazil so the whole jobs argument goes down the tubes.”

In the absence of EU renewable targets for 2030, however, Malins said that the cleaner fuel process in Europe could still be continued with carbon intensity fuel standards similar to those in California, an extension of the bloc’s Fuel Quality Directive, or fiscal measures by European states.

Urbancic said that the US already had advanced biofuels targets which would likely deter its small industry from importing to the EU, while Brazil was likely to focus its industry on aviation.
