Vegan handbags made of pineapple, cactus and cork could help save the planet

Vegan handbags made of pineapple, cactus and cork could help save the planet

LOS ANGELES – Pineapples aren’t just for piña coladas anymore.

As fashion looks to become more sustainable, designers are trying unusual materials – such as pineapple, cactus and cork – to create handbags and other apparel traditionally made of vinyl or leather.

Instead of relying on petroleum-based synthetic fabrics that dominate fashion, Remington Reble and other designers use vegan textiles intended to help heal the environment.

“Concern for the environment is increasing. And so with that comes those conscious choices to change how you live and consume,” said Reble, an Arizona State University fashion graduate who makes handbags from cactus.

Purveyors of plant-based leather alternatives tout their products as good for the environment because they don’t have toxic chemicals and, of course, don’t involve animal cruelty.

The trend delights animal-rights activists.

Plant-based leather is a “better option because it doesn’t involve factory farming, which is what animal leather is coming out of,” said Ashley Byrne, spokeswoman for People for the Ethical Treatment of Animals, or PETA.

Helga Douglas, creator of the Los Angeles fashion brand Svala, makes handbags out of pineapple and cork.

“I was always looking for handbags and accessories that were made from more sustainable, animal-friendly fabric,” said Douglas, who sells her bags online. “And I couldn’t really find exactly what I was looking for. So that’s why I created Svala.”

Her handbags are made of a leatherlike material called Piñatex, which is derived from pineapple leaf fibers collected by farming cooperatives in the Philippines. The processing is finished in Spain.

Because Piñatex is a byproduct of pineapple harvest and doesn’t require any extra land water or fertilizer, its manufacturer says on its website that it is one of the most sustainable textiles on the market.

She said customers are always curious about Piñatex, but she assures them they won’t smell like a tropical cocktail. The product holds up if taken care of properly, Douglas said.

“It really does require some maintenance in the same way that you would care for leather,” like occasional waxing and buffing, she said.

Svala’s cork bags also are popular, Douglas said. In contrast to the stoppers in wine bottles, the cork is finished in a way that makes it smooth to the touch with a glossy finish.

Adding to its sustainability, cork bark can be harvested without killing the tree; the bark just grows back. Douglas said Svala has associated itself with a nonprofit organization that helps plant trees.

In Arizona, Reble recently started his brand Ribellè to market his cactus handbags. The project ties into his upbringing as a native Arizonan.

“My mom … sent me an article about cactus leather,” he said. “And then that combined with living my entire life in Arizona. It just immediately clicked.”

He obtains his cactus leather from a company called Desserto, based in the Mexican state of Jalisco. On its website, Desserto says the material is made with the pads of nopal cactus.

Desserto says it grows its cactus without irrigation. The pads are harvested every six to eight months, then cleaned, mashed and dried for three days. Non-toxic chemicals are mixed with the organic raw material to produce a leather substitute. Because the spines are removed during processing, wearers needn’t worry about being pricked.

Reble said the cactus leather substitute feels the same as traditional leather. Other businesses are using cactus for jackets and automobile seats.

For instance, Mercedes-Benz says its new Vision EQXX electric car “is made with animal-free textiles – like cactus fibers, mushrooms and vegan silk – that provide a luxurious finish from upholstery to door handles.”

Vegan leather substitutes are somewhat less durable than animal leather because they’re thinner and more sensitive to cracks and tears. However, careful use can extend a product’s lifespan up to 10 years, Reble said.

Like Reble, Douglas is enthusiastic about these materials.

“I think that it’s really great to have a fabric that is very sustainable and eco-friendly,” Douglas said.

Algae biofuel back from dead, now with carbon capture

Algae biofuel back from dead, now with carbon capture

Algae biofuel stakeholders have been stuck in the doldrums for years, but in an odd twist of fate, the fossil fuel industry could help algae make a comeback. Apparently the new plan is to pair algae farming with waste carbon from gas power plants and other industrial operations. In addition to biofuel, algae farming can also produce animal feed, fish food, nutritional supplements and toiletries for people, and bioplastic products.

 

Why Algae Biofuel?
CleanTechnica spilled plenty of ink on the area of algae biofuel research some years ago, during the Obama administration. Unlike other energy crops, algae can be grown in ponds or human-made structures without taking arable land out of circulation, and it has a rapid growth-to-harvest cycle. The high oil content of certain strains of algae is another leading attraction, and the algae R&D pathway can lead in a carbon negative direction.

On the down side, figuring out an economical way to cultivate algae and extract the oil at an industrial scale is a challenging endeavor, especially when the over-arching goal is to reduce carbon emissions rather than adding them.

The picture was looking bright in the early 2000s, up through the Obama administration. However, by the time former President Obama left office in 2016, oil prices were crashing. The relatively low cost of petroleum seemed to put the idea of a bioeconomy fueled by algae biofuel to bed.

Nevertheless, the Energy Department’s National Renewable Energy Laboratory was among those continuing to invest in algae research projects, and the algae field continued to branch off into new angles. In 2018, for example, the Energy Department was funding the algae bioplastics angle. In 2020 researchers were exploring the idea of hooking up with high speed 3-D printing. The Mars mission has also sparked a new burst of interest in the algae biofuel field.

Carbon Capture To The Rescue
In January of this year the Energy Department’s Bioenergy Technologies Office (BETO) launched the new AlgaePrize competition for students, aimed at developing “the next generation of bioeconomy professionals by expanding novel solutions to production, processing, and new product development on the way to gigaton-scale algae commercialization for fuel, food, products, and carbon dioxide utilization/sequestration.”

If you caught that thing about carbon dioxide, that’s where the happy dance for natural gas stakeholders comes in. Carbon capture from flue gas could turn out to be a value-added element that improves the bottom line for algae farming.

That’s where BETO seems to be heading. Last week the office announced a $16.5 million round of funding for six algae projects related to carbon dioxide capture.

The six projects were selected for their potential to demonstrate an improvement in carbon capture by algal systems leading to biofuels and other products, while also cutting costs and decreasing overall greenhouse gas emissions.

“Algae can grow on waste CO2, functioning as a carbon sink. This algae biomass can then be used to create low or no-emissions biofuels and bioproducts which displace GHGs,” BETO noted.

 

Natural Gas Hearts Algae Biofuel
Not all six of the new BETO-funded projects are focusing on carbon captured from flue gas. The Colorado School of Mines, for example, plans to put its pond-grown algae system through its paces using concentrated carbon dioxide from direct air capture.

Another awardee, Colorado State University, is working on an algal system that functions efficiently on atmospheric carbon.

Three of the other awardees are focusing on carbon dioxide from industrial fossil energy users including power plants: Dioxide Materials, MicroBio Engineering, and the University of Maryland’s Center for Environmental Sciences. A fourth awardee in the point source class is Global Algae Innovations, which is focusing more specifically on flue gas from a naphtha-fired power plant.

If the biofuel angle doesn’t work out at commercial scale, other aspects of the algae biofuel market could come into play.

Market analysts are forecasting growth in the algae market in the coming years. Consumers are on the prowl for healthy diet supplements, especially among the up-and-coming generation.

“Rise in the acceptance of algae-based food products and a growing popularity of vegan food are expected to emerge as trends in the algae market. Algae are already widely employed in bioplastics, cosmetics, food, bio-packaging, biofuel, and pharmaceutical and nutraceutical products,” observes the firm Transparency Market Research.

 

The Long Algae Biofuel Game Of ExxonMobil
All this activity puts the on-again, off-again algae biofuel journey of ExxonMobil into perspective.

ExxonMobil spearheaded the charge into shale gas after the Bush Administration lifted Clean Water Act regulations in 2006, and the company continued to double down on gas acquisitions even as prices plummeted.

 

Next Steps For Algae
ExxonMobil, for one, is excited. The company lists the following benefits compared to corn ethanol and other biofuels made from land-based energy crops:

Unlike making ethanol and biodiesel, producing algae does not compete with sources of food, rendering the food-vs.-fuel quandary a moot point.
Because algae can be produced in brackish water, including seawater, its production will not strain freshwater resources the way ethanol does.
Algae consume CO2, and on a life-cycle basis have a much lower emissions profile than corn ethanol given the energy used to make fertilizer, distill the ethanol, and to farm and transport the latter.
Algae can yield more biofuel per acre than plant-based biofuels – currently about 1,500 gallons of fuel per acre, per year. That’s almost five times more fuel per acre than from sugar cane or corn.
That’s all well and good, but it’s about time for ExxonMobil and other fossil energy stakeholders to stop digging more carbon up from the ground and start taking giant steps towards a more sustainable energy profile.

Capturing carbon dioxide at power plants is a step in the right direction, but it doesn’t change anything in terms of the local environmental impacts of fossil energy extraction, and it doesn’t make a dent in the amount of fugitive emissions escaping from drilling sites, transportation networks and storage facilities.

To the extent that algae farming at gas power plants enables more gas extraction, it’s just another form of greenhouse gas whack-a-mole.

Either way, it looks like algae farming at power plants has a window of opportunity. Last November ExxonMobil re-upped its collaboration with Synthetic Genomics, under the new name of Viridos. If you have any thoughts about that, drop us a note in the comment thread.

From sneakers made of banana leaves to fish scale dresses, fashionistas hunt for eco-friendly materials

From sneakers made of banana leaves to fish scale dresses, fashionistas hunt for eco-friendly materials

Sneakers made from banana or pineapple leaves, dresses from nettles or fish scales – the search for sustainable materials has taken the fashion industry to some wild places.

Experts warn these new textiles are not a quick fix for fashion’s enormous problems with over-consumption and waste, but may be a necessary step in developing cleaner technologies.

“You could possibly eat the final product,” said Hannes Schoenegger, co-founder of Bananatex, which uses leaves from banana ..

He was speaking at the Premiere Vision Paris conference, where industry professionals gather to find out which fabrics will dominate coming seasons.

“We only harvest the sides of the plants, and they’re already growing in the forest, so no chemicals, pesticides or even water are used,” Schoenegger added.

He was among multiple stalls presenting new bio-sourced materials.

Brazil-based Nova Kaeru offered leather made from the discarded scales of the giant pirarucu fish and another from the tropical “elephant ear” plant.

Nearby, Ananas Anam showed off some Nike shoes made from waste pineapple leaves.

 

Nettles are in
These textiles can be relatively niche, but some companies are determined to bring them into the mainstream.

Spanish firm Pyratex offers multiple options, from recycling the waste of corn and sugar cane production, to making fibres from Icelandic seaweed, Chinese bamboo or Austrian wood.

“It’s not about replacing cotton with one alternative crop. It’s about finding a wide variety of substitutes to make sure that nothing is over-used,” said spokesperson Pilar Tejada Lopez.

One plant getting particular interest is the nettle, which can be turned into a silk-like and incredibly strong fabric that can be used in everyday and luxury clothing.

It highlights the fact that many of these technologies are not new.

“Nettles have actually been used for clothing for centuries, but we have largely forgotten,” said Lopez.

“Part of our job is reintroducing these ideas that have been lost.”

 

Natural limits
Others warn of over-reliance on new materials in the drive towards sustainability.

“Replacement materials serve no purpose if we continue to make the same amount of clothing,” said Victoire Satto, of The Good Goods, a media firm specialising in responsible fashion.

They could even add to the problem if scaled up by encouraging further deforestation to make way for newly fashionable plants, she said.

That is why companies like Baananatex refuse to go beyond natural farming limits.

“Our project is part of a reforestation programme, a good way of revitalising soils and providing work to local families,” said Schoenegger.

“There’s a natural limit and we won’t go beyond that, because then it would be harmful.”

Pyratex similarly puts a lot of emphasis on partnering with responsible farmers, and avoiding the ultra-complex supply chains that make it difficult for clothing companies to know who grows their raw materials and in what conditions.

But Satto says more research is also needed on the durability of bio-sourced materials, since half the ecological damage from an item of clothing is linked to its disposal.

“If the product only lasts six months, that’s enormous in terms of environmental impact,” she said.

 

Iterations
Ifeanyi Okwuadi, an award-winning British designer, says his focus is on how clothes are made – not what they are made from.

“When I speak about sustainability, I’m talking about the construction – right down to using the right stitch-length for each stitch because that kind of minute detail affects the longevity of the garment when you put it in the wash,” he said.

He says many bio-sourced materials are still evolving.

“Right now, there’s a lot of buzzwords to draw you in, but eventually we won’t need to say it’s from bananas or whatever — it will just be plant-based fibres.”

“I don’t use them in my work because the tech at the moment is quite primitive. But I see them as iterations, like with all technology, and we need these innovations.”
