Toothbrush pops open for recycling in Seymourpowell’s Un-Made concept

British design studio Seymourpowell has put cheap electronic goods under the spotlight with Un-Made, a project imagining four possible ways to design for quick disassembly and recycling.

As part of the project, Seymourpowell devised four automated disassembly mechanism concepts using an electric toothbrush as an example for their animated graphics.

Each of the mechanisms could be built into a product during manufacturing and then activated in a factory at the end of the item’s life.

The first Un-Made concept is a pin mechanism. Similar to the action of opening a SIM card slot on a smartphone, it involves poking a pin into a small, sealed pinhole on the rear of the product to release the internal components.

The second concept is a vacuum mechanism. It involves placing the product into a vacuum, causing closed cell foams and air-sealed features within it to expand and bust the external housing open.

Third, there is a piston mechanism that works by pushing a piston through a cap on the bottom of a device and forcing all of the internal components upwards until they emerge through the top.

The final concept involves using UV glue – a type of adhesive that deactivates under ultraviolet light. In this concept, the product is placed into a specially lit chamber to release the clamshell construction.

The Un-Made project was led by Eddie Hamilton, a senior industrial designer at Seymourpowell, who was driven to make the work after researching what electric toothbrush to buy for himself.

“Inevitably I went for the cheap one, at which point Amazon smugly pointed out they’d sold 10k+ of that model last month alone,” said Hamilton.

“As an industrial designer, I spend time obsessing over the product I’m working on, typically thinking of it in isolation,” he added.

“But one thing I occasionally fail to remember or adequately picture is the true scale of that product once manufactured. 10,000 units sold per month seems vast.”

Using Amazon’s bestsellers list, Hamilton ascertained that fabric shavers, steam irons, wireless doorbells, wireless computer mice, digital tyre inflators and USB-C adaptors were all items selling in their thousands each month, at a price of less than £20.

While designing products so they can be repaired is important, the associated expense may not be something that customers can justify for small items sold at this price point, Hamilton said.

“Even if we change societal attitudes, the bottom line is whether you should open that cheap toothbrush to replace a failing battery when you only paid £24.99 for it two years ago,” he said.

“I’m optimistic for some product categories to get the ball rolling, namely expensive and bulky items. But I’m also a realist that we need alternative strategies adjacent to repair. This is where we must design for disassembly.”

In Hamilton’s view, disassembly and recycling is a worthy “next best option” to repair for cheaper objects, as it keeps the materials in a circular material flow.

The Un-Made design team took inspiration from Agency of Design’s Design Out Waste project, which looked at three strategies for keeping a toaster out of landfill. But they particularly wanted to explore just how efficient the disassembly process could be made through automation.

The cheaper and easier the process, they say, the more motivation there is for companies to pursue this approach and recover the components and materials inside their devices.

“A huge part of the reason e-waste ends up in landfill is because of product complexity and the inherent challenges involved in their disassembly,” Seymourpowell lead designer Alex Pearce told Dezeen.

“To date, because e-waste has been considered too time-consuming and costly to disassemble – there has been no (commercial) incentive strong enough to make it a viable option.”

The fourth Un-Made concept uses UV light to dissolve the glue holding the device together

The materials inside even cheap devices are valuable, Pearce points out, particularly when there are supply shortages or when it comes to rare-earth minerals.

“When you consider that more gold exists within a ton of e-waste than within a ton of gold ore dug from the ground, a straightforward economic imperative becomes clear for companies who are able to recover and reuse these materials,” said Pearce.

Seymourpowell imagines disassembly taking place either at the manufacturer’s facilities following a take-back procedure, or potentially at a public recycling centre if disassembly processes have been sufficiently standardised.

The London-based studio is known for its innovative product and transport designs, as well as concepts that challenge current norms. Recent projects from the studio have included the two-in-one reusable Bottlecup and a spaceship cabin for Virgin Galactic.

A bio-based electric toothbrush is compostable and recyclable 

Spotted: The second largest contributor to plastic pollution after plastic bags, plastic toothbrushes are almost all non-recyclable because of the number of tiny parts they contain. Bamboo brushes have become a common replacement, yet for those who love electric toothbrushes, what can they use instead? UK company SURI has the answer. The name stands for Sustainable Rituals, and the brand’s first product is the Sustainable Sonic Toothbrush. 

A mix of recyclable and compostable components, plus a modular design, gives SURI’s electric toothbrush an extensive life. Replacement brush heads come in packs of three, and the company provides a compostable return mailer with each order for users to send back used brush heads in for recycling.

Most current toothbrushes use nylon bristles, a material that contributes to the inability of waste management facilities to recycle them. SURI, on the other hand, uses castor oil for the bristles and corn starch for the brush head. The handle is easy-to-recycle aluminum. Available accessories include a UVC light self-cleaning and charging travel case, a magnetic mirror mount, and a paper washbag. Most components are recyclable or compostable, and the company provides instructions on its website for deconstructing products if a user is unable to ship them back for recycling.

Toothpaste tubes are also part of the personal hygiene pollution problem, and Springwise has spotted innovations seeking to change this through refillable toothpaste dispensers as well as toothpaste tablets.

Suri unveils modular electric toothbrush with recyclable brush head

London-based toothbrush company Suri has created Sustainable Sonic Toothbrush, an electric toothbrush with an aluminium body and brush heads made from plant-based materials that can be recycled after use.

Suri founders Mark Rushmore and Gyve Safavi designed the Sustainable Sonic Toothbrush after learning that nearly every plastic toothbrush ever owned still exists in the world. They believe it could replace plastic toothbrushes – four million of which they say are disposed of each year around the world.

“Over the last few decades, electric brushes haven’t meaningfully changed; only novelty features, such as Bluetooth-enabled apps, have emerged on the market under the guise of innovation,” Rushmore told Dezeen.

“While most are bulky composites of plastic that can’t be recycled because they’re welded shut, it’s no surprise that every year over four billion brushes – including electric ones – are thrown away and end up either in landfill or in our oceans,” he added.

“We wanted to create a brush that champions design, performance and sustainability without compromise.”

The Sustainable Sonic Toothbrush heads, which come with medium to soft bristles are made from corn starch and castor oil.

Traditional toothbrushes usually have bristles made from nylon, which end up as landfill waste or marine waste for decades.

By contrast, Suri claims that they are 100 per cent recyclable. Users can send their used brush heads back to the brand in the post in compostable paper bags provided by the company.

By using a pre-paid compostable return service, Suri hopes to make the process of changing heads as easy as possible and discourage its customers from switching back to disposable brushes out of convenience.

The company recommends changing the brush head every three to four months as you would traditional electronic toothbrush heads.

Alternatively, the brush heads can be recycled at home by removing the bristles and disposing of them in a home waste bin where the brand says they will eventually break down in a couple of years.

According to the toothbrush manual, the metal clips that connect the bristles to the head and the inner core of the head can also be recycled at home in the same way as aluminium foil. The remaining cornstarch shell can be sent to a local industrial composter.

Meanwhile, the aluminium body can be sent back to Suri to be repaired or have its rechargeable Li-ion batteries replaced once they run out. The batteries are designed to last for up to 30 days without being charged.

“Once a customer’s battery dies, they can send back the brush to us to replace the battery or complete any other repairs, if necessary,” Safavi explained.

“Whilst we’re refurbishing the brush, we will send that customer a replacement brush so they can still brush their teeth.”

Despite Suri’s sustainability claims, the brand sources the materials and manufactures its toothbrushes in China. As a result, the product’s carbon footprint is much larger than it would be if the product was manufactured locally.

“All components are sourced in China but we found that we could reduce our scope three emissions by not shipping parts to the region to assemble and then ship on once again,” Rushmore said.

“We are looking to make production more local, but this was the most optimal way to launch with sustainability in mind.”

Cutting down on virgin plastic in toiletries is one way that designers are trying to make their products more sustainable.

New York toiletries company By Humankind created refillable deodorants and dehydrated mouthwash that come in paper pods made of biodegradable paper while design studio Visibility developed a re-fillable container for plant-based deodorant brand Myro that uses 50 per cent less plastic than a regular disposable toiletry.

Suri’s Sonic Toothbrush has been shortlisted in the product design category of the Dezeen Awards. Other products shortlisted for design awards include Tenuto 2, a wearable vibrator by MysteryVibe that is designed for those who experience erectile dysfunction.
