Plastic Eating Microbes Found In The Alps

A Chilling End To Plastics

Hello Tech Lovers!

In the Alps, microbes that can east plastic at low temperatures have been discovered.

Microorganisms capable of destroying plastic polymers have previously been discovered and as a result, scientists and businesses have latched onto bioengineering enzymes found in bacteria and fungi, as a means to tackle plastic pollution.

However, since the majority of those found require high temperatures to function, the industry has been limited due to the process been costly and not carbon neutral.

The most effective performers are two fungi discovered by the Swiss Federal Institute, which work at just 15 degrees Celsius. They are capable of digesting biodegradable polyester-polyurethane (PUR), and two commercially available biodegradable mixtures of polybutylene adipate terephthalate (PBAT) and polylactic acid (PLA.)

PUR is commonly used in artificial textiles, PBAT is used widely in industries for packaging, and PLA is found in biomedical applications.

A total of nine fungi, and eight, bacteria species from multiple genera found, are able to digest PUR. And a total of 14 fungi and three bacteria, managed to eat mixtures of PBAT and PLA

During the hunt for a microbe capable of digesting in the cold, the team studied 19 strains of bacteria and 15 fungi growing on plastic that had been left behind, or intentionally buried in Greenland, Svalbard, and Switzerland.

Scientists let isolated microbes grow as single-strain cultures in a dark laboratory at 15 degrees Celsius. Molecular techniques were used to identify them.

In the study published in the journal Frontiers in Microbiology, in total, 59% of strains, including 11 fungi and eight bacteria, could digest PUR at 15 degrees Celsius

Scientists Use Mushrooms to Make Biodegradable Computer Chips

The Future Of Computer Chips

Hello Tech Lovers!

The skin from the stems of a mushroom could potentially offer a sustainable alternative to insulative substrates in computing chips.

Scientists are looking at alternatives to common components like the mircochip, as production of electronic devices increases. Peeling the skin from the mycelium of a mushroom can protect chips from heat up to 392°F (200°C.)

The equivalent of the scale of ewaste produced each year

Scientists from Johannes Kepler University in Austria, discovered that once dried, the skin was found to be not only heat resistant, but lasted for years – withstanding being bent and folded thousands of times without wearing or tearing.

The fungus, Ganoderma lucidum grows on dead rotting wood in European mountains. As it reaches maturity, it creates a fibrous skin to protect its own substrate which if peeled, can be used to protect microchips.

Currently computing chip bases tend to be made with un-recyclable plastic materials and the increase of electronic devices has not been paired with an increase in their lifespan. Throwing them away is more economical for users than replacing individual parts. “The vast number of devices produced every day along with the decrease of their lifetime inevitably results in the generation of enormous amounts of electronic waste,” wrote the authors of a paper published in Science Advances.

“Circular economy and recycling concepts alone cannot solve the growing waste crisis. Electronics research, and especially electronic materials research, thus must shift its focus from strictly high-functionality concepts to sustainable, cost-effective approaches.”
