The looming rooster feather disaster is lastly getting some consideration from science, as researchers discover methods to mine wads of fouled, moist, waste feathers for precious keratin protein. In one of many newest developments, a workforce from ETH Zurich and Nanyang Technological College Singapore Followers has utilized a tailor-made type of keratin to make bio-based membranes for zero emission hydrogen gasoline cells.

Hen Feathers Can Pack a Highly effective Hydrogen Gasoline Cell Punch

On a worldwide degree, the ETH/Nanyang analysis workforce estimates that 40 million metric tonnes of rooster feathers are incinerated yearly for lack of something higher to do with them.

The workforce did discover one thing higher to do with them. Nonetheless, utilizing keratin to manufacture membranes for hydrogen gasoline cells just isn’t so simple as it sounds, contemplating the punishing setting of a gasoline cell.

Earlier than being rendered into membranes, the researchers processed their feather-derived keratin into the type of extraordinarily effective fibers referred to as amyloid fibrils. If that rings a bell, you might be considering of the amyloid fibrils deposited on organs and tissues within the human physique, that are usually indicative of a pathological situation.

As defined by our good friend over on the US Nationwide Institutes of Well being, amyloid fibrils are related to Mad Cow illness, amongst others. Nonetheless, additionally they have a secret superpower.

“Amyloid fibrils are extraordinarily secure and proof against degradation. They’ve been described as having an identical tensile power to metal, a property that they share with their structural cousin, silk,” NIH observes.

That explains why the brand new bio-based membrane from rooster feathers is at house within the tough and tumble world of hydrogen gasoline cells. Gasoline cells generate electrical energy via a response between hydrogen and ambient oxygen, shepherded by a catalyst. The membrane in a gasoline cell performs a central function and it had higher be as much as snuff.

“It [the membrane] permits protons to cross via however blocks electrons, forcing them to move via an exterior circuit from the negatively charged anode to the positively charged cathode, thereby producing an electrical present,” ETH explains.

Extra Hen Feathers For Extra Hydrogen Gasoline Cells

As for what to do with the leftover feathers, that’s a great query. In accordance with ETH, rooster feathers encompass 90% keratin. That also leaves 10% of 40 million tonnes of post-keratin waste to dispose of every yr.

Leaving that apart, the ETH/Nanyang workforce just isn’t the one group within the utility of rooster feathers to hydrogen gasoline cells.

Again in 2009, CleanTechnica took observe when a workforce of researchers on the College of Delaware gained a modest grant to deploy keratin from rooster feathers as a hydrogen storage medium for gasoline cell Electrical Autos.

The researchers set a aim of assembly Vitality Division benchmarks for value and capability. Hen feathers had been a great wager, partly as a result of using a bio-based materials may assist resolve prices that bedevil different supplies, together with end-of-life disposal prices.

“So as to resolve the H2 storage downside in gasoline cell Vehicles, varied sorts of nano-structured supplies have been investigated and produced, none of which may fulfill these targets solely,” the workforce noticed. “Their disposal strategies and degradability are nonetheless an enormous query mark. Moreover, the costs of those supplies are extraordinarily costly.”

Constructing A Higher Hydrogen Storage System

The UD workforce uncovered their feather-derived keratin to a excessive warmth therapy to carbonize it for hydrogen storage. The top consequence was a cloth with a a lot bigger floor space than uncooked keratin fibers.

“When keratin-based rooster feathers are warmth handled by managed pyrolysis, hole carbon microtubes are shaped with nanoporous partitions,” the workforce defined. “Their floor space will increase considerably by the formation of fractals and micropores thus enabling extra hydrogen adsorption than untreated feather fibers.”

That specific thought appears to have fallen by the wayside at UD, however others have picked it up. In 2019, for instance, the Institute of Physics hosted a presentation on the subject of carbonized rooster feathers as a hydrogen storage medium.

One Hen Feather To Rule Them All

Hydrogen gasoline cells are only one department of the rooster feather saga.

The US Division of Agriculture has been on the lookout for an answer to the rooster feather disaster no less than way back to 2000, when it assessed an effort to upcycle feathers for the whole lot from filters and diapers to insulation and fabric padding.

That concept appears to have gotten misplaced someplace, however in 2009, USDA researchers had been exploring the thought of constructing biodegradable flower pots from rooster feathers. Hen feathers are a major supply of nitrogen in addition to keratin, the thought being to compost the pots on the finish of their lifespan.

Carbonized rooster feathers have additionally been investigated for quite a few different makes use of, together with EV batteries and bio-based plastics.

The seek for an upcycling answer additionally consists of deploying feather-derived protein to provide textiles. Final yr a analysis workforce in Nebraska reported important progress on their feather-to-textile challenge, although challenges nonetheless stay.

Final yr a multinational analysis workforce additionally printed a research on using rooster feathers as a comparatively cheap, biobased supply of waterproof coatings for meals packaging.

European Union Decided To Resolve Hen Feather Disaster

The EU emerged as a hotspot of rooster feather exercise final Could, when it launched a brand new collaboration referred to as UNLOCK. The brand new initiative goals at extracting keratin from the 3.6 million tonnes of feathers generated by the European poultry business every year.

The challenge is run by the Spanish impartial analysis group CIDETEC Basis, which notes that solely about 25% of Europe’s feathers are re-used. Feed and fertilizer are the first makes use of for salvaged feathers within the EU.  The remainder go to waste.

UNLOCK has tasked itself with capturing extra of the waste and upcycling feathers into seed trays, nonwoven textiles, mulch movies, hydroponic foams, and different supplies utilized by the agriculture business.

In addition they anticipate end-of-life-benefits from the nitrogen launched into soil when the merchandise are biodegraded.

Hydrogen Gasoline Cells: The Subsequent Era

The UNLOCK initiative is scheduled to conclude in 2025, so keep tuned for extra on that. In the meantime, the seek for extra sustainable supplies for hydrogen gasoline cells goes on.

The hydrogen a part of the equation starting to come back underneath management. Pure fuel continues to be the primary supply of the worldwide provide, however various sources together with water and biomass are rising (see heaps extra CleanTechnica protection right here).

Discovering alternate options for the membranes utilized in hydrogen gasoline cells is a complete ‘nother kettle of fish. The proprietary polymer Nafion has dominated the roost ever because it was invented within the Sixties. The model is owned by Chemours, which spun out of DuPont in 2015.

The place’s Congress?

In fact, no story about rooster feathers and hydrogen gasoline cells could be full with no point out of the US Home of Representatives, the place the Republican majority has empowered the lunatics to run the asylum.

Republican members of Congress fired Consultant Kevin McCarthy from the all-important put up of Speaker on October 4, and the Home can not conduct regular enterprise till they change him, which they appear decided to not do.

That’s all effectively and good for any member of Congress who goals to make hash out of probably the most highly effective democracy within the trendy world (spoiler alert: all of those Republicans), however the remainder of us want to understand how lengthy these people anticipate to gather their salaries from us taxpayers with out doing any precise work.
