From Pond Scum to Food Bowl, Dutch Designers 3D-Print Algae Into Everyday Products

You might not think of pond scum as something that's good for the environment, but Dutch designers have developed a bioplastic made from algae that they hope could replace petroleum-based plastics.

According to Dezeen, Eric Klarenbeek and Maartje Dros have been cultivating live algae and processing it into material that can be used for 3D printing. This algae polymer can be churned into everyday items, from shampoo bottles to bowls to trash bins. 


Their innovation can currently be seen at Museum Boijmans Van Beuningen in Rotterdam as part of its Change the System exhibition.

Klarenbeek and Dros have also 3D-printed from other types of biopolymers, such as mycelium, potato starch and cocoa bean shells. One day, the duo hope to set up a local network of biopolymer 3D printers, which they have dubbed the "3D Bakery."

"Our idea is that in the future there will be a shop on every street corner where you can 'bake' organic raw materials, just like fresh bread," Klarenbeek told Dezeen. "You won't have to go to remote industrial estates to buy furniture and products from multinational chains. 3D printing will be the new craft and decentralized economy."

Klarenbeek believes that the 3D Bakery could be a reality within 10 years.

The designers tout that their project is one way to help stop the planet's unsustainable consumption of fossil fuels.

"All around the world in recent decades enormous amounts of fossil fuels—materials that lay buried in the ground for millions of years—have been extracted," they said. "In this relatively brief period, a vast amount of carbon dioxide has been released into the atmosphere, with damaging consequences. It is therefore important that we clean the CO2 from the atmosphere as quickly as possible and this can be done by binding the carbon to biomass."

Klarenbeek and Dros researched algae for three years with Wageningen University, Salga Seaweeds, Avans Biobased Lab and other institutions in the Netherlands. They have since established a research and algae production lab at the Luma Foundation in Arles, France.

The pair pointed out that their creations do more than just replace plastic, as algae can also suck up carbon dioxide, a greenhouse gas that drives global climate change.

"Algae is equally interesting for making biomass because it can quickly filter CO2 from the sea and the atmosphere," they said. "The algae grow by absorbing the carbon and producing a starch that can be used as a raw material for bioplastics or binding agents. The waste product is oxygen, clean air."

Celebrating the Biggest Conservation Wins of 2017

It's been a big year for conservation.

Together we assured the world that the U.S. is still an ally in the fight against climate change through the We Are Still In movement, a coalition of more than 2,500 American leaders outside of the federal government who are still committed to meeting climate goals. WWF's activists met with legislators to voice their support for international conservation funding. And we ensured that Bhutan's vast and wildlife-rich areas remain protected forever through long-term funding.

Cell Phone Radiation Risks: California Issues Groundbreaking Guidelines

By Olga Naidenko

This week, California officially issued groundbreaking guidelines advising cell phone users to keep phones away from their bodies and limit use when reception is weak. State officials caution that studies link radiation from long-term cell phone use to an increased risk of brain cancer, lower sperm counts and other health problems, and note that children's developing brains could be at greater risk.

3 Extreme Weather Events in 2016 'Could Not Have Happened' Without Climate Change, Scientists Say

Three of 2016's extreme weather events would have been impossible without human-caused climate change, according to new research.

The Bulletin of the American Meteorological Society published a collection of papers Wednesday focused on examining the effect of climate change on 27 extreme weather events last year. The research found that climate change was a "significant driver" in 21 of these weather disasters, and that three events—the temperatures making 2016 the hottest year on record, the heat wave over Asia in the spring, and a "blob" of extremely warm water in the Pacific—"could not have happened" without climate change.

Netherlands Launches Landmark Zero-Subsidy Wind Power Auction

The Netherlands has launched the world's first “zero subsidy" tender on Friday to build 700 megawatts of offshore wind. Shortly after the announcement, the country already found its first bidder.

Zero subsidy tenders have been labeled as a “game-changer" for the sector because it means that potential bidders would rely solely on wholesale electricity prices without financial aid from the government.

World's Largest Solar-Wind-Storage Plant Planned for India

A wind, solar and battery storage plant is being planned for the southeastern Indian state of Andhra Pradesh, which has faced power woes in recent months due to grid failure.

The renewable energy facility will consist of 120 megawatts of solar, 40 megawatts of wind, 20-40 megawatt-hours of battery backup and will be spread over 1,000 acres in the district of Anantapur.

How Cities Can Meat the Climate Challenge

By Kari Hamerschlag and Christopher D. Cook

Addressing a crowd of mayors gathered in his hometown last week, former President Obama called on the "new faces of American leadership" on climate change to take swift action to spare our children and grandchildren from a climate catastrophe. Twenty-five U.S. mayors signed the "Chicago Charter," affirming a commitment from their cities to meet the Paris agreement target for greenhouse gas reductions by 2025.

Mercury From Industrialized Nations Is Polluting the Arctic—Here’s How It Gets There

By Daniel Obrist

Scientists have long understood that the Arctic is affected by mercury pollution, but know less about how it happens. Remote, cold and seemingly pristine, why is such an idyllic landscape so contaminated with this highly toxic metal?

I recently returned from a two-year research project in Alaska, where I led field research into this issue alongside fellow scientists from the University of Colorado; the University of Nevada's Desert Research Institute; the University of Toulouse and the Sorbonne University in France; and the Gas Technology Institute in Illinois.
