waste – Watch documentaries of all time

Recycling e-waste – Good for business and the environment |

One way to tackle e-waste is to repair devices rather than throw them out. More companies are doing just that, from recycling solar modules to renting out second-hand smartphones. Their goal is to reduce e-waste and protect the environment.

Experts predict that by 2030, more than one million tons of solar modules will end up as waste in Germany alone. With his company 2ndlifesolar in Hamburg, engineer Martin Wilke wants to ensure that as many of these discarded modules as possible are recycled, for example as a small-scale solar panel system on a balcony. The company also recycles the raw materials in the discarded modules, such as silver and silicon.

And in the French city of Strasbourg, Elie Assémat is working to eliminate e-waste altogether. He’s the co-founder of the cooperative Commown, which has been renting out smartphones, computers, and headphones since 2018. Assémat is primarily concerned with sustainability and promoting product longevity.

India, meanwhile, has become a dumping ground for e-waste from all over the world, including illegal waste from Europe. Tens of thousands of people make a living from processing and reselling e-waste under dangerous working conditions. Swiss environmental scientist Dea Wehrli wants to tackle the problem with a project called E(co)work. It allows Indian scrap metal workers to rent a work or storage space that is safe and in line with regulations.

How technology makes life easier – and what’s still up to you / UNSEEN (5/5) |

Albert — Wed, 14 Jul 2021 16:00:05 +0000

Green tech could help to clean our air, secure our food and protect our cities. An innovative plastic upcycling machine is one promising device made in Taiwan. But can technology really save the planet?

Sometimes it seems like a bad dream: floods, air pollution, traffic jams. Sometimes it feels like we’re surrounded by eco-monsters. But they can be defeated. YouTuber Alex Lin presents state-of-the-art devices. Arthur Zhang builds machines for upcycling plastics. And Japanese researchers are even working on mirrors in space.

DW presents: UNSEEN (Five-part documentary series)
Invisible guests in your food, your hometown sinking, unhealthy dust hiding in your lungs. Discover heroes with amazing solutions – and inspiration for a better life!

Keeping your kids safe from air pollution / UNSEEN (1/5): https://youtu.be/KrsGQpSv5Co
How to avoid microplastics in your food / UNSEEN (2/5): https://youtu.be/acMYHAmNLlE
Fighting the floods: how not to lose your city / UNSEEN (3/5): https://youtu.be/9BTrzAGhy8U
How to cope with traffic jams (without going crazy) / UNSEEN (4/5): https://youtu.be/Hh1Do3PQCWA
How technology makes life easier – and what’s still up to you / UNSEEN (5/5): https://youtu.be/EJi3Vxdyqv0

UNSEEN opens your eyes. We travel through Southeast Asia and discover stories about people whose lives could be yours. In Indonesia, children suffer from air pollution – something doctors, architects and entrepreneurs are fighting with innovative and original concepts. Then we head to Malaysia for an episode in learning how to deal with microplastics in food. We follow a fan of great cuisine on his own personal journey. What’s safe to eat and drink? Which products are good, and which don’t measure up? Next up is Thailand’s capital Bangkok, one of Asia’s sinking cities. Its inhabitants prepare for future floods, adapting their city and seeking tools to make their homes safe. In Vietnam we get caught in gridlock. Nothing new! But this time, we’re stuck with some cool rappers teaching people how not to go crazy in traffic. And finally, in Taiwan, it’s all about green tech. Learn about the hopes and limits of the new technologies being developed to solve life’s challenges. Join us on an exciting trip in five episodes – one that will open your eyes to beastly challenges and promising solutions!

The 3D printing revolution |

Albert — Sat, 23 May 2020 17:00:31 +0000

Three-dimensional printing promises new opportunities for more sustainable and local production. But does 3D printing make everything better? This film shows how innovation can change the world of goods.

Is the way we make things about to become the next revolution? Traditional manufacturing techniques like milling, casting and gluing could soon be replaced by 3D printing -saving enormous amounts of material and energy. Aircraft maker Airbus is already benefiting from the new manufacturing method. Beginning this year, the A350 airliner will fly with printed door locking shafts. Where previously ten parts had to be installed, today that’s down to just one. It saves a lot of manufacturing steps. And 3D printing can imitate nature’s efficient construction processes, something barely possible in conventional manufacturing. Another benefit of the new technology is that components can become significantly lighter and more robust, and material can be saved during production. But the Airbus development team is not yet satisfied. The printed cabin partition in the A350 has become 45 percent lighter thanks to the new structure, but it is complex and expensive to manufacture. It takes 900 hours to print just one partition, a problem that print manufacturers have not yet been able to solve. The technology is already being used in Adidas shoes: The sportswear company says it is currently the world’s largest manufacturer of 3D-printed components. The next step is sustainable materials, such as biological synthetic resins that do not use petroleum and can be liquefied again without loss of quality and are therefore completely recyclable. This documentary sheds light on the diverse uses of 3D printing.
