What Is Upcycling?

Upcycling is defined as creating something new from discarded materials by repairing, refurbishing, or repurposing them. What formed from a growing concern about collective waste has become an outlet of creativity for many people who are focused on keeping things out of landfills. There are many techniques used to upcycle, as well as many products that can be upcycled. In a world where recycling is becoming limited, upcycling is a great way to avoid throwing objects away.

Upcycling, Downcycling, and Recycling

The phrases "upcycling" and "recycling" are often used interchangeably, and the Environmental Protection Agency's definition of recycling sounds very similar to definitions of upcycling. However, there are important distinctions.


Recycling is the process of collecting materials that would otherwise be trash, processing them, and turning them into new products.

Glass recycling, for example, is a closed-loop system that sees glass turned back into glass. Yet it is rare for materials to be able to be recycled so seamlessly, and in many situations, "recycling" is incorrectly used in place of "downcycling" or "upcycling".


Downcycling is the breakdown of materials into their base form to create a new product of lesser quality and value.

Downcycling decreases the quality and value of items because there are often contaminants within recycled materials, such as the paint on an aluminum soda can. A common example of downcycling is printed paper being turned into toilet paper. Construction and demolition waste are also cases of this. Downcycling presents a problem because, eventually, the materials are of such low quality that they become unusable.

This is not the case with upcycling, which either maintains or increasing the value of the new item. The added advantage is that the materials maintain their quality. Upcycling helps to create a circular economy, where materials can be constantly reused and not turn into waste. It is a practice that has been used throughout history as means to reduce waste in an inexpensive way, and it's now used in a wide range of processes — which are expanding the definition as a result.

What Can Be Upcycled?

Since upcycling repairs and repurposes materials in ways that add value to its compositional elements, so many products have the potential to be upcycled. Hobbyists and professionals across many industries create new products from old ones in an effort to increase sustainability and reduce costs. Below are just some examples.

Sometimes, the source material is evident in the new product; other times, the product is so removed from the source that it is completely unrecognizable. Plastic is often an example of the latter. Many fashion brands are using plastic waste from the ocean in their shoes and apparel. Other companies make use of recycled plastic bottles. While clothing is a popular subject of upcycling, artisans also create jewelry and functional art from seemingly mundane objects. Do-it-yourself (DIY) projects are creating an abundance of household goods from simple plastics like plastic bags, laundry detergent containers, and plastic bottles.

From replacing buttons to refashioning a T-shirt, upcycled clothing has long been a popular style choice. A quick search in Pinterest or YouTube will provide a plethora of tutorials on ways to upcycle clothes and fabric scraps. Textiles can be recycled just about 100% of the time. However, the threads of recycled materials, such as cotton, do not have the quality of the original fabric, which makes the life cycle of the resulting product shorter. Upcycling textiles, therefore, is a more sustainable option.

In West Africa, scrap aluminum is being used to create cooking pots and utensils. In 1988, Marc Newson created an aluminum sofa from the reclaimed material. Aluminum continues to be lauded for its flexible nature and ability to be crafted into sleek designs. With the damaging environmental affects of mining aluminum, recycling and upcycling are becoming popular alternatives. Recycling is now the main source of this malleable metal in the United States and is often used to manufacture soda and beer cans. But, the uses don't end there. Secondhand aluminum has been used to create musical instruments, furniture, and vehicles.

Glass that hasn't been mixed with any other materials can easily be recycled, but that hasn't stopped people from upcycling it as well. Glass jars and bottles can be used to create household items such as vases, storage containers, and even planters for succulents.

Industrial Waste

The rise of architectural upcycling is here. In The Upcycle: Beyond Sustainability--Designing for Abundance, authors William McDonough and Michael Braungart envision a world where industrial production creates little waste and no toxic chemical pollution; this aspirational world is based on the concept of creating with recycling and reuse in mind. Research has been done to manufacture glass ceramics from industrial waste, which have been shown to be heat- and moisture-resistant and usable in kitchen appliances as well as in the electrical and space industries. Upcycle artists have also found themselves using these non-recyclable materials in the fabrication of art and furniture.

McDonough and Braungart believe that design should be non-destructive and harmonious with the environment to model the greatest designer — Mother Nature herself. Pending every industry's desire to produce with a zero waste mindset, upcyling habits will continue to rise.
