Recyclable stool made from potato scraps and sawdust can be used for firewood

Posted on by

There are plenty of designs that advertise being sustainable, but many of them stop halfway through the product’s life cycle. They are usually made from sustainable or renewable materials, and some, but not all, are made with a reduced carbon footprint. That said, not many cover what happens after the product has served its purpose, which often means adding to the already enormous amount of waste we produce annually. Fortunately, there are some designs that do take that into account, creating a circular economy where the product or its materials can be used for other purposes. One example is this cork-like stool that, true to its wooden nature, can actually be used like firewood to heat up a space or, better yet, fuel workshops that will produce the materials to be used to create another stool.

Wood is a much-loved material by designers and producers. It has an innate beauty and texture that’s hard to reproduce artificially, it is biodegradable, and, to some extent, also renewable. It takes time for trees to grow, however, and not all parts of the wooded material actually end up getting used. Many get left on the cutting room floor, either as small chunks or, worse, sawdust. The latter is easy to take for granted until they pile up and become pollutants themselves, at least until they dissolve and disintegrate over a long period of time.

Briket is a stool that tries to solve that material waste problem by giving a new purpose to waste byproducts not just from woodworking but also from the food industry. In a nutshell, this nine-legged stool is made from sawdust scraps as well as potato scraps, both biodegradable and environment-friendly materials we throw out by the ton every day. Creating the parts of the stool itself isn’t exactly hard either, as it mostly involves compressing these minute pieces until they become a rigid and solid mass. This, in theory, can be done anywhere there’s an abundance of wood waste, which practically means sawmills, carpentry shops, workshops, and other places that work with large quantities of wood.

What makes the Briket stool more interesting, however, is how it can be used for some unrelated purpose when it has reached its end of life. Inspired by wooden pellets used for bonfires and fire pits, it can serve as fuel to heat up a place or keep the fire of a workshop going, letting it serve people one last time before finally biting the dust, pun intended. In fact, the legs of the stool can be individually removed and replaced, making the piece of furniture almost immortal as long as there are replacement parts available.

In terms of aesthetics, Briket has a unique raw appearance and texture that is more similar to cork than wood, something that might not sit well with everyone’s tastes. Because of that, some people might even have doubts about its stability and reliability as furniture you will sit on. Fortunately, that doesn’t seem to be the case, and Briket stands as a shining example of a truly sustainable design from start to finish.

Odd sustainable stool concept prioritizes minimizing materials over recycling

Posted on by

The majority of sustainable designs today focus on using responsibly sourced or biodegradable materials as well as the ability to recycle components at the end of the product’s life. While these are indeed a big leap compared to common production practices, it’s still from the ideal. Even sustainable materials like wood, metal, or bioplastics produce material waste that still gets discarded at the end of the production process. And depending on the materials involved, recycling can actually consume more energy and even result in more pollution, offsetting whatever benefits it should have brought. Another approach to sustainability is to actually reduce the materials used and, therefore, the materials that need to be recycled, as what this rather unconventional “two-piece” stool design tries to propose.

Designer: Kitae Pak

The less materials you use for a product, the more products you can make out of that material. If a single 1,220mm x 2,440mm sheet of plywood would normally yield 24 circular plates with a diameter of 310mm, you could potentially squeeze 219 plates with a diameter of 120mm. That’s the kind of increase in yield that the Dots stool concept is claiming, making more efficient use of a material without compromising on quality, at least in theory.

The concept accomplishes this by completely redesigning what a stool is expected to be. Yes, it’s still a piece of furniture for seating, but there’s no hard rule that the seat has to be one large and whole piece. Instead of a single big circle, the Dots stool utilizes two smaller discs to support the body at rest, hence the name. It delivers the same function but at a significantly lower material consumption right from the start.

With this minimalist design, which consists of two wooden rods for legs and recycled plastics to connect the pieces into a stable whole, you can make 4 times more Dots stools than a regular stool using the same materials. This kind of conservation means that the production process itself would use less materials and energy to produce the same number of stools, while recycling would also use less energy and water as well. And since it’s mostly made of wood, the stool can also be repurposed for other designs or returned to the Earth one way or another.

While the design does check all the right sustainability boxes, it does raise questions on conform and stability. It’s arguable that it does serve its function well, but neither its appearance nor its ergonomics inspire complete confidence. It’s not a complete loss, however, as the experiment proved that there’s still a lot of room for improvement even for already sustainable designs.
