A WEEE waste recycling challenge?

Sarah Harvey, Project Curator of The Rubbish Collection, talks to Dr Philip Morton, Chief Executive of REPIC about the challenges of dealing with growing volumes of electrical and electronic waste.

REPIC is the largest not-for-profit WEEE (Waste Electrical and Electronic Equipment) recycling scheme in the UK. Instead of letting valuable or harmful waste and scarce raw materials go to landfill, REPIC’s job is to recover and transport used electrical goods and batteries to specialist treatment plants. Upon arrival at the plant, the WEEE waste can be safely handled and recycled into new usable raw materials.

What is WEEE waste?

Every year, people in the UK buy around 1.5 million tonnes of electrical and electronic equipment, like toasters, TVs, washing machines and computers. We throw away about one million tonnes of equipment, so WEEE waste is one of the fastest growing waste streams in the UK and in the EU. It’s important that we take action now to stop it from piling up.

Some of the components used to make electronic goods can be hazardous and harmful to the environment, while others can be recycled and reused. Some are even precious and contain gold, silver, indium or palladium. It’s amazing to think that WEEE contains 40 times more gold than gold ore!

What are the biggest challenges faced by the industry in recycling and recovering these materials?

A big problem is the difficulty in separating the complex scarce trace metals using the technology currently available. Different proportions of trace materials are present in different bits of WEEE and some materials bind together, making separation a challenge.  At present, only a tiny percentage of these metals is captured in the recycling process, so it isn’t sustainable. 

What can people do to help?

Just as we separate our plastic bottles and tins from paper and compostables, we need to separate our old electrical appliances and take them to a local recycling centre.

As with electricals, it’s easy for batteries to end up in landfills if the proper recycling channels are not used. Batteries contain chemicals that can be hazardous if released into our soil, water and air.

But there is an alternative. You could save your batteries and take them to special battery bins at shops, schools and recycling centres. This ensures the batteries are recycled responsibly.

Our top three tips are:

  • Repair or re-use used electricals if possible
  • Recycle, but don’t make a special trip (check our website www.responsible-recycling.co.uk).
  • Choose energy and eco-efficient products where possible when buying replacements

What do you think the industry will be like in 50 years time? 

To meet the new EU directive we need to recycle 85 percent of WEEE generated in the UK by 2018. The value of WEEE will be higher as there will be less rare metals and raw materials to extract from the Earth.  Advances in technology will mean that electrical goods will be even lighter, more compact and flexible. Think projected keyboards, flatter TV screens – we’re already seeing roll up TV screens – so expect more to come.

 

 

Your future without antibiotics?

Georgie Ariaratnam, Assistant Content Developer, blogs about the rise of antibiotics, the subject of a display in the Museum’s Who Am I? gallery

Antibiotic resistance is one of the biggest challenges of our time. It affects all of us, so perhaps unsurprisingly, it was declared the winner of the Longitude Prize 2014.

At the Science Museum, we decided to examine this topic in more depth with a new exhibit, Your future without antibiotics?, which explores the rise of antibiotic resistance and the latest research to tackle it.

The exhibit, currently on display in our Who am I? gallery, changes every few months, giving the Science Museum the opportunity to explore current and significant research stories in health, genetics and neuroscience. With over a million people visiting the Who am I? gallery each year, it’s important to design exhibits that are interesting and relevant to our visitors’ lives.

We chose to tell three main stories in the display case. The Rise of Resistance looks at how bacteria have become resistant, Radical Research focusses on the latest research to tackle resistance and Stop the Spread explores how to prevent the spread of infection.

The display features unique and intriguing objects to tell these stories. You can see a Star Trek-inspired hand-held ‘tricorder’ which uses a virus to identify bacterial infection.  Alongside, you can spot a keyboard and mobile phone cover coated with the world’s first light-activated antimicrobial surface that also works in the dark. Other items include a bio-engineered medical honey which can kick start the healing process in wound treatment. There is even a giant, lime green stick insect, whose guts researchers are studying for new antibiotic compounds.

To develop the display case, we spoke to many institutions that focus on tackling antibiotic resistance including the World Health Organisation, Department of Health, Public Health England and Antibiotic Action. The exhibit also features research from scientists at University College London, University of Birmingham and the University of Leicester.

Your future without antibiotics? opened on 18 July and will be on display in the Science Museum’s Who Am I? gallery until late November 2014.

Going down the drain

In the latest of our blogs linked to The Rubbish Collection, Curator Sarah Harvey talks to Nick Mills, Waste Innovation Manager at Thames Water about what happens to our sewage and what the future holds for wastewater.

Sarah: What do Thames Water do with our sewage?

Nick: We have 350 sewage works and 68,000 miles of sewers across our region, which stretches from East London to the Cotswolds in the west. Last year, we removed and treated 4,369 million litres of sewage from 15 million customers. At our 350 sewage works we treat the sewage to remove contaminants and return it safely to the environment, it is often cleaner than the water in the river.

Sarah: What happens to the end products of the processing?

Nick: The main end-product of the sewage treatment process is something called sludge. This energy rich by-product is put to good use in anaerobic digestion, producing renewable energy that helps power our treatment sites. The digested sludge is then recycled to agricultural land.

Sarah: What are the biggest challenges you face in dealing with our sewage/ waste water?

Nick: London has outgrown its sewer system. The Victorian sewers are in great condition, but simply not designed for today’s population. They were designed for just over two million but are used today by just over six million. The proposed Thames Tideway Tunnel will stop tens of millions of tonnes of raw sewage flowing into the Thames every year via the outfall system. It is a must-do job. We can’t keep treating the Thames as a sewer.

Sarah: What are the strangest or most difficult things to deal with that people throw down the drains?

Nick: ‘Bin it – don’t block it’ is our campaign to end the misery caused by fatbergs. Leftover cooking fat and oil poured down the sink will set hard. This creates stinking, pipe-blocking fatbergs beneath your house or in your street.

Wet wipes are another big no-no because they are made of plastic. They don’t break down like toilet tissue, clinging to fat and clogging up the system. If drains get blocked, what you flush can come back up through your toilet or even your sink.

Sarah: What can consumers and organisations do better?  Is there a top 3 list of things people could do differently to help?

Nick: Our message is simple, if it’s not water, toilet tissue or poo, please… ‘Bin it – don’t block it’.

Sarah: What do you think the industry will be like in 20 years’ time? What are the new innovations and technologies that you are exploring at the moment?

Nick: In 20 years’ time I can see the wastewater industry becoming a net energy producer, by employing more efficient processes and increasing energy recovery. Combining advanced anaerobic digestion and technologies like pyrolysis, large increases can be made. Our Innovation team are busy demonstrating this at the moment. Phosphorus, a finite resource essential to life as we know it, will be recovered at every major sewage works and sold competitively as a fertiliser to farmers, this has also been demonstrated recently at our Slough sewage works by the Innovation team.

Sarah: What did you think when you first heard about Joshua Sofaer’s The Rubbish Collection project?

Nick: I think it is great. It shows the harsh reality of waste, but at the same time reveals the great work that people do behind the scenes to keep society moving. I hope it will encourage a new generation to start what is a very interesting and rewarding career as there are huge challenges yet to be solved.

Phase 2 of Joshua Sofaer’s The Rubbish Collection runs at the Science Museum until 14 September 2014.

Sending messages across the Atlantic: 156 years on from the first transatlantic cable

Chloe Vince, Science Museum Volunteer, tells the dramatic story of the laying of the first transatlantic cable, one of the highlights of our new Information Age gallery, which opens in October.

If you needed to send a message to North America, you wouldn’t think twice about drafting an e-mail, hitting ‘send’ and your message arriving in the recipient’s inbox almost instantly.

In 1858, however, communications were much slower. In those days, a message would take up to 10 days to arrive. This was the time it took for a ship to travel across the Atlantic.

Things changed in the August of 1858, when the first message was sent via a transatlantic telegraph cable, which ran from the east coast of North America to the West Coast of Ireland. Messages could now be sent in a matter of minutes, dramatically changing the history of transatlantic communication.

Experimenters had been investigating batteries and electromagnetism to develop a communication system since the early 19th century. The first practical system was executed successfully in the UK by the partnership of Charles Wheatstone and William Cooke. They used an electrical current to deflect magnetic needles which could be made to point to letters on a backboard. By the time of the 1858 transatlantic cable, their system had been developed and widely adopted for railway signalling across Britain.

American experimenter Samuel Morse (of Morse code fame), was also working on developing telegraphy. His system used a single circuit to send an electric signal along a wire to a receiver at the other end. Instead of using needles indicating letters of the alphabet, Morse’s system used a code of dots and dashes to spell out words. Morse received funding to use this technology to set up a telegraph system between Washington and Maryland in the USA. The telegraph became an instant success. People relished the ability to send and receive information much more quickly than before, and as a result the telegraph system expanded across America and Europe.

Soon after, in 1856, the Atlantic Telegraph Company was set-up with the objective of laying a cable across the Atlantic Ocean, connecting America with Europe. Luckily, opinions of the technology were high, which meant shares in the company sold quickly. As soon as enough money was raised, the first transatlantic cable, consisting of seven copper wires and recorded as weighing one ton per nautical mile, was laid from America to Ireland.

Queen Victoria sent the first official transatlantic telegram. She sent a message to US president James Buchanan congratulating him ‘upon the successful completion of this great international work.’  The message travelled through 2,500 miles of cable and took 16 hours, a dramatic improvement on the 10 days it would have taken beforehand. The same message was repeated back to Valencia in Ireland in only 67 minutes.

Unfortunately, the success enjoyed by this first transatlantic cable did not last. There were problems with the cable, and within a month it had failed completely. However, the desire for speedy transatlantic communication was great enough to attract more funds to try again.  A further attempt in 1866 was successful.

The consequence of this new form of communication was huge. By the end of the 19th century, new technologies began to emerge. The telegraph was replaced by telephony and these days we rely on the internet for high speed communication. However, the telegraph was the first technology that allowed us to communicate quickly and reliably over long distances, and acted as a turning point in communication history.

You can explore more about the laying of the first transatlantic cable in our Information Age gallery, which opens on 25 October.

 

Shedding light on the matter of rubbish

In the latest of our blog series linked to The Rubbish Collection, the Science Museum’s Inventor in Residence Mark Champkins finds an ingenious use for our discarded materials.

The second phase of The Rubbish Collection exhibition is open at the Museum until 14 September. Having documented every piece of waste that passed through the Museum for a month, this second phase is a chance to see what would have been thrown away.

Of the material that hasn’t been selected for display, I collected a small box of bits that I hoped to turn into a product that we might sell in the shop. I like the idea that with a little bit of effort and imagination, items that would otherwise be chucked, can be turned into something desirable. Unfortunately the collection of items in the box that I had gathered didn’t look at all desirable. A couple of umbrellas, some bits from a light fitting, an old copper funnel, an ash tray, some plastic cutlery, some glass cups and a selection of ball bearings didn’t look very promising.

The germ of my idea came from digging out the copper funnel and investigating it further. It was heavily corroded and covered in green verdigris, but underneath was structurally solid, and a beautiful shape.

I read somewhere that vinegar could be used to clean copper, so I popped down to the café, to get a couple of sachets to try out. It turns out it does a reasonable job on lightly tarnished areas, but can’t handle the extent of corrosion on the funnel. However, it did encourage me that the funnel could be saved.

Next I pulled apart the umbrellas, lined up everything from the box and had a think what I might make. A happy coincidence was that the handle from the umbrella fitted exactly into the top of the funnel.

My first thought was to make some sort of loudspeaker people could shout through. Next, I thought the umbrella handle might plug the funnel to make a water-tight vase or container of some sort. Finally, looking at the shining clean patch of copper I thought, coupled with a 1950s-style squirrel cage bulb, it might make a really nice light fitting.

The next step was to recondition the copper funnel. In the basement, the Museum has metal and wood workshops responsible for building, installing and maintaining the structures for new exhibitions. Amongst their equipment is a sandblasting machine, which I used to blast the corrosion from the funnel.

I decided to leave the matt finish left from the sand blasting on the inside surface, and polish up the outside. Using Brasso and eventually a buffing wheel I polished up the outer surface.

To ensure the lamp remains pristine, I decided to use a polymer based lacquer, applied in the workshop’s spray booth.

Finally I added the umbrella handle, and a lighting flex and fitting. I think the finished light looks rather good. It’ll be available for purchase in the Museum shop from mid August.

The Historic Heart of our Information Age Gallery

Dan Green, Content Developer, reflects on the incredible story of the Rugby Tuning Coil, one of the star objects of the Science Museum’s brand new Information Age gallery which opens in October.

The aerial inductance coil from Rugby Radio Station will soon have a new home at the Science Museum – see it being installed in the video below.

Measuring 6 metres high and resembling a series of giant spiders’ webs, this monumental coil is a powerful reminder of the invisible infrastructure which supports our desire to communicate.

Based at Rugby Radio Station, where it was housed in a huge cathedral-like room, the coil played a vital role in tuning a huge radio transmitter that sent out very low frequency signals. It was part of a huge system that linked the transmitter to the aerial masts, enabling messages to be sent and telegrams to be transmitted. During its long life, Rugby Radio held a huge personal resonance for many individuals, connecting people to each other, to the world and to home.

Rugby Radio Station began transmitting very low frequency signals on 1 January 1926 using the call sign GBR. Once the world’s most powerful radio transmitter, its very low frequency waves could follow the curvature of the Earth to travel very long distances, enabling one-way communication to Britain’s Empire. It transmitted wireless telegraph messages from the British Foreign Office, standard time signals from Greenwich, news bulletins, personal telegrams and Christmas greetings.

Although first hailed as a matter of national pride, in later years Rugby Radio Station was a hidden secret that played an important role in the Cold War, as its very low frequency signals could be picked up by submarines.

Godfery Dykes, one of many submarine communication operators, sat in a claustrophobic communications cabin, hunched over the radio, headphones on, sick bucket between his legs, receiving the Morse code signals. His role was to write down in pencil the dots and dashes coming through at the incredible speed of 30 words a minute, a rate that was undecipherable to the untrained ear. The dots and dashes would then be decoded and the messages delivered:

‘GBR meant a lot to us and we used the letters GBR in many ways. At the start of our patrol I used to think Goodbye BeRyl (my wife) …simply to hear Rugby’s call sign meant to me all those I loved back in the UK were still safe. I well remember moments of excitement on coming shallow to periscope depth after many hours down deep, watching the depth gauge creep slowly past 150 feet, 125, feet, 100 feet and then 75 feet, faint at first, that most lovely sound started to fill my ears – God Bless Rugby, GBR’

On 31 March 2003, 77 years after it transmitted its first Morse message, Rugby Radio station ceased broadcasting its very low frequency signals around the world. A year later, the twelve 250m high masts that radiated out Rugby’s signals were demolished, marking the end of an era. Former station manager Malcolm Hancock was invited to detonate the first explosion:

 “They had been there for so long and the red lights (on top of the masts) had always been there whenever you came home. That is what all the local people in Rugby say, ‘Oh yeah, the thing we’re going to miss is not seeing the red lights saying – oh we’re nearly home now’”.

The coil was donated to the Science Museum by BT Heritage and Archives soon after the decommissioning of Rugby Radio Station. From 25 October, you can see the Rugby Tuning Coil displayed in public for the first time at the centre of the Information Age gallery, as reflected in this artist’s impression.

An Antarctic Expedition

Assistant Curator Sarah Harvey looks back at Sir Ernest Shackleton’s Antarctic expedition, which launched a century ago today.  

On this day (8 August) 100 years ago, a ship called the Endurance set sail from Plymouth, bound for Antarctica. The ship carried Sir Ernest Shackleton’s Imperial Trans-Antarctic Expedition, the goal of which was to make the first transcontinental crossing of Antarctica through the South Pole, from the Weddell Sea to the Ross Sea.

The expedition failed when Endurance became trapped in pack ice and, after 9 months, was eventually crushed and sank, stranding Shackleton and the crew on the ice. Despite this failure the trip became famous as an epic feat of endurance, as Shackleton and his crew made a desperate and heroic bid for escape in three tiny boats, crossing the Southern Ocean to the island of South Georgia. Sadly, three lives were still lost: Victor Hayward, Aeneas Mackintosh and the Rev. Arnold Spencer-Smith from the Endurance’s supply ship the Aurora.

It was the last great expedition of what is known as the heroic age of Antarctic exploration, and for 100 years has provided inspiration for both explorers and artists alike, including author Tony White whose thought provoking and innovative latest novel, Shackleton’s Man Goes South, is the first novel ever to be published by the Science Museum. More information about Shackleton’s expedition and the novel, which is available as a free e-book until April 2015, can be found in the Science Museum’s Atmosphere gallery.

Drawing on tales of adventure from the past and cutting-edge new scientific research into the effects of climate change, White imagines a terrifying future where people are fleeing to Antarctica, instead of escaping from it; in a hot world instead of a cold one.

The author says that he became fascinated not only by Shackleton’s amazing feat of heroism, but the way that the story has been told. “I wondered what new resonances those early tales — and moving images — of Antarctica a century ago might have now when that great continent’s ice sheets are at risk because of climate change, and what kind of Shackleton myth might inspire future generations of migrants to Antarctica. Migration is being seen as a form of adaptation to climate change, and the novel suggests that climate change refugees, setting out in tiny boats on equally desperate and epic voyages, might be the Ernest Shackletons of our day.”

There are zeppelins over South Kensington and boat people in the South Atlantic. Among them are Emily and daughter Jenny, travelling south to safety and a reunion with John who has gone ahead to find work. They travel with Browning, a sailor who has already saved their lives more than once. In the slang of their post-melt world, Emily and Jenny are refugees known as ‘mangoes,’ a corruption of the saying ‘man go south’.

Transforming materials – the recycling journey

In this week’s blog linked to The Rubbish Collection Curator Sarah Harvey follows the route of the Science Museum’s recycled rubbish.

Joshua Sofaer’s art installation The Rubbish Collection showcases the sometimes surprising materials that are created from the everyday rubbish produced by staff, contractors and visitors at the Science Museum. After documenting all the Museum’s waste for 30 days we have traced where it goes, and how it is recycled and transformed from rubbish back into valuable materials.

For recyclable rubbish put into the Museum’s recycling bins the first port of call in the journey is the Grundon Material Recovery Facility (MRF) at Colnbrook near Heathrow. Here it is separated out into several different recycling streams. First magnets remove the ferrous metals (like steel cans) and non-ferrous metals (such as aluminium cans) then sophisticated infra-red technology identifies and separates the remaining rubbish into paper, card, glass and several different types of plastics. Any rubbish that cannot be recycled, or pieces too small to be captured, are taken to the Lakeside Energy from Waste plant for incineration, so no rubbish goes to landfill. At the end of the sorting process the materials are baled as raw materials for resale to companies who take on the next stage of processing.

For each material the recycling and recovery processes are necessarily very different, but it was interesting to find that there is always a loss of some material which cannot be recovered or usefully reused. For the plastics and the glass that loss comes from paper labels and glues that are soaked off in the washing process, forming an unpleasant sticky mulch which gets sent for incineration. Even for the steel and aluminium cans which can be endlessly recycled, there is still some loss from the paints and pigments used in printing their branded logos and decoration.

As processes improve and new technology is developed, hopefully one day these materials will either be captured for future use, or the waste will be designed out altogether. The model for keeping 100% of the materials in circulation is known as the circular economy. Sometimes only a small change is needed. In the exhibition we have the plastic label and mixed flake that is retained from PET plastic recycling. By using plastic labels instead of paper the material can be more easily collected and recycled to make new products like plastic bags.

There is lots of information on the web about the processing of different materials. Some of the online resources I have found most helpful during this project are:

Aluminium
Steel
PET plastics
HDPE plastics

Phase 2 of Joshua Sofaer’s The Rubbish Collection is now open at the Science Museum and runs until 14 September 2014.

Rubbish that powers homes and builds roads

In this week’s blog linked to The Rubbish Collection, Curator Sarah Harvey looks at some of the materials that are on display in the exhibition.

The second phase of Joshua Sofaer’s The Rubbish Collection art installation has involved tracing the journeys of the Science Museum’s rubbish, to find out where it goes, and how it is processed. This has enabled us to work out what materials to bring back for display, and in what quantities, to represent 30 days’ worth of Science Museum waste.

Rubbish leaves the museum via a variety of different companies but the vast majority is taken by Grundon Waste Management. It goes to their site at Colnbrook, near Heathrow, which holds three centres; a transfer station, a Materials Recovery Facility and the Lakeside Energy from waste plant, co-owned by Viridor Waste Management.

Today I’m going to focus on the materials on display from the Energy from Waste plant. When you think of an incinerator that burns rubbish you might picture a dirty, sooty, very smelly and unpleasant place, but it’s actually an extraordinary, almost clinically clean building (except for the container where the rubbish is held), and it’s surprisingly beautiful with a giant claw grabbing up to six tonnes of rubbish at a time to feed the incinerator fires.

All the Science Museum general (non-recycled) waste goes to Lakeside to be incinerated. Four products come out of that process: energy, incinerator bottom ash, air pollution control residue and clean air. The largest output is energy, with the plant providing enough to power 50,000 homes per year. We have calculated that the energy produced by incinerating one month of Science Museum waste is enough to light one of our gallery bulbs for nearly 24 years.

The energy is produced by burning the rubbish for approximately 3 seconds at 950 degrees centigrade, which is long enough to combust most materials. At the end of the process, incinerator bottom ash is left over. This ash still contains large pieces of metal which are separated and sent to be recycled, and the ash itself is left to ‘mature’ so that chemical reactions can take place that lower its pH value. This aggregate is then used in the construction industry, primarily in road building. You could be driving on your old rubbish.

One of the most remarkable things about the incineration process is that the air that comes out of the plant is actually cleaner than the air that goes in. This is because it is very carefully filtered to contain the toxins released during burning. The filtered ash is known as air pollution control residue (APCr). Historically this toxic ash would have been contained in hazardous waste landfill, but new technologies and research are now finding uses for it. Grundon have invested in a company called Carbon8 who use carbon dioxide to neutralise the toxic heavy metals and materials, making them permanently non-hazardous. This safe ash can then be used as an aggregate and, alongside other recycled materials including wood, makes the ‘Carbon Buster’ carbon-neutral breeze blocks we have on display in The Rubbish Collection.

It’s been very encouraging to find that the Science Museum rubbish is producing some useful and valuable products through incineration. However, one of the big findings from our documentation of the Museum’s waste was that there is still a lot of recyclable material ending up at the incinerator. Those materials retain much more value when they are recycled so by continuing to improve and refine our recycling systems, and through new initiatives like separating our food waste, we hope in the future to decrease our general waste further.

Phase 2 of Joshua Sofaer’s The Rubbish Collection is now open at the Science Museum and runs until 14 September 2014.

Modern art is Rubbish

In the latest of our series of blogs linked to The Rubbish Collection Science Museum Inventor-in-Residence Mark Champkins looks back at Phase 1, while Project Curator Sarah Harvey gives us a sneak preview of Phase 2 before it opens on 25 July.

Phase 1 – Mark Champkins, Science Museum Inventor-in-Residence

Tuesday 15 July was the last day of sorting through Museum waste for The Rubbish Collection project, and my last chance to put in a shift filtering through discarded drinks bottles and leftover lunches.

The project is fascinating. It aims to examine what constitutes the waste that passes through the Museum, where it would normally go, and what might be usefully recycled.

The exhibition is split into two parts. The first involves the collection of every piece of waste generated by the Museum over a month. A team of volunteers has been sorting and photographing the contents of the Museum’s rubbish bags, and pulling out items of particular interest. The second part will start on 25 July, and will be an exhibition of cleaned and collated rubbish materials.

As I began my shift, what struck me first was the smell of the gallery. It’s a sweet, fruity smell, not unlike over-ripe apples. It comes from the vast amount of sugary drinks and half eaten fruit thrown into the bins, the likely source being the hundreds of packed lunches eaten in the Museum every day. Throughout the Museum, the usual bins have been replaced with ‘General Waste’ and ‘Recycling’ bins. It soon became clear to me that in order to avoid the worst of the smell, the bags to pick out to sort through are the ones marked ‘Recycling’. This avoids the majority of the decomposing foodstuffs.

The task is to open up the bags, lay out the contents on a large white table, sort the contents as you see fit, and then snap a photo of the arranged items on an overhead camera. The opportunity to arrange the rubbish in whatever way you want has brought out the creativity of the volunteers. To this end, within a few days, a tumblr account was opened to show off some of the most imaginative of the layouts. Amongst my favourites are the seascape, composed of blue plastic bags and fruit, and blazing sun in the sky, made from bread sticks, paper towels and what looks like parsley. You can have a look here.

After half a dozen bags, a disheartening pattern starts to emerge. Much of what is being thrown away is perfectly good. Lots of the food is unopened or untouched. Leaflets and flyers are almost always pristine. It’s as though the bins are being used to de-clutter, rather than being a place to put things when they have reached the end of their useful lives. It seems inexplicable how many of the items have ended up in the bins. Three wheelchairs have been collected, over a dozen shoes, two fridges, a bra and a giant toothbrush.

Spurred by the some of the weird and wonderful items collected I have set myself a challenge. Like a Science Museum Womble, I aim to filter through the items left behind to put together some items that can be repurposed and redesigned to make a one-off product, that we can sell in the Museum shop. Watch this space…

Phase 2 – Sarah Harvey, Project Curator, The Rubbish Collection

After 30 frenzied days of documenting all the Science Museum waste, you might have expected artist Joshua Sofaer to take a well-earned break. No such luck. Since the documentation finished on 15 July, The Rubbish Collection has remained a hive of activity and an almost miraculous transformation has taken place. Gone are the sorting tables, bin bags and faint whiff of old packed lunch; in their place Joshua has created an intriguing and magical exhibition showcasing 30 days of Science Museum rubbish.

The exhibition is comprised of some of the bizarre and surprising items that were retained from the bins in the documentation phase of the project, displayed alongside almost 18 tonnes of materials processed and recycled from the Science Museum rubbish. Both the scale and the beauty of these materials and objects is quite unexpected, and I don’t want to ruin the surprise, so I’m just going to give you some teaser images (below). The exhibition opens to the public at 11am on Friday 25 July, so please come down and experience the wonder of ‘rubbish’ for yourself.
