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

Science

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."

It is far too easy to view scarcity and poor quality of water as issues solely affecting emerging economies. While the images of women and children fetching water in Africa and a lack of access to water in India are deeply disturbing, this is not the complete picture.

The city of Flint, Michigan, where dangerous levels of pollutants contaminated the municipal water supply, is a case in point — as is, more recently, the city of Newark, New Jersey.

The Past is No Longer a Guide to the Future

We get ever closer to "day zeros" — the point at when municipal water supplies are switched off — and tragedies such as Flint. These are not isolated stories. Instead they are becoming routine, and the public sector and civil society are scrambling to address them. We are seeing "day zeros" in South Africa, India, Australia and elsewhere, and we are now detecting lead contamination in drinking water in cities across the U.S.

"Day zero" is the result of water planning by looking in the rear-view mirror. The past is no longer a guide to the future; water demand has outstripped supplies because we are tied to business-as-usual planning practices and water prices, and this goes hand-in-hand with the inability of the public sector to factor the impacts of climate change into long-term water planning. Lead in drinking water is the result of lead pipe service lines that have not been replaced and in many cases only recently identified by utilities, governments and customers. An estimated 22 million people in the US are potentially using lead water service lines. This aging infrastructure won't repair or replace itself.

One of the most troubling aspects of the global water crisis is that those least able to afford access to water are also the ones who pay a disproportionately high percentage of their income for it. A report by WaterAid revealed that a standard water bill in developed countries is as little as 0.1 percent of the income of someone earning the minimum wage, while in a country like Madagascar a person reliant on a tanker truck for their water supply would spend as much as 45 percent of their daily income on water to get just the recommended daily minimum supply. In Mozambique, families relying on black-market vendors will spend up to 100 times as much on water as those reached by government-subsidized water supplies.

Finally, we need to understand that the discussion of a projected gap between supply and demand is misleading. There is no gap, only poor choices around allocation. The wealthy will have access to water, and the poor will pay more for water of questionable quality. From Flint residents using bottled water and paying high water utility rates, to the poor in South Africa waiting in line for their allocation of water — inequity is everywhere.

Water Inequity Requires Global Action — Now.

These troubling scenarios beg the obvious question: What to do? We do know that ongoing reports on the 'water crisis' are not going to catalyze action to address water scarcity, poor quality, access and affordability. Ensuring the human right to water feels distant at times.

We need to mobilize an ecosystem of stakeholders to be fully engaged in developing and scaling solutions. The public sector, private sector, NGOs, entrepreneurs, investors, academics and civil society must all be engaged in solving water scarcity and quality problems. Each stakeholder brings unique skills, scale and speed of impact (for example, entrepreneurs are fast but lack scale, while conversely the public sector is slow but has scale).

We also urgently need to change how we talk about water. We consistently talk about droughts happening across the globe — but what we are really dealing with is an overallocation of water due to business-as-usual practices and the impacts of climate change.

We need to democratize access to water data and actionable information. Imagine providing anyone with a smartphone the ability to know, on a real-time basis, the quality of their drinking water and actions to secure safe water. Putting this information in the hands of civil society instead or solely relying on centralized regulatory agencies and utilities will change public policies.

  • Mice exposed to nicotine-containing e-cigarette vapor developed lung cancer within a year.
  • More research is needed to know what this means for people who vape.
  • Other research has shown that vaping can cause damage to lung tissue.

A new study found that long-term exposure to nicotine-containing e-cigarette vapor increases the risk of cancer in mice.

It may seem innocuous to flush a Q-tip down the toilet, but those bits of plastic have been washing up on beaches and pose a threat to the birds, turtles and marine life that call those beaches home. The scourge of plastic "nurdles," as they are called, has pushed Scotland to implement a complete ban on the sale and manufacture of plastic-stemmed cotton swabs, as the BBC reported.
