Upcycling: corrugated plastic can be repurposed
Corrugated plastic, also known as corrugated polypropylene or coroplast, is a strong and lightweight material used in packaging, construction, and industrial applications. It is made of twin-wall polypropylene sheets with a wavy or ribbed pattern. While corrugated cardboard is a greener alternative to corrugated plastic, the latter can still be recycled or upcycled.
Corrugated plastic can be upcycled into new products without undergoing a complete breakdown. Used corrugated plastic sheets can be transformed into various items, such as storage bins, signs, or reusable packaging. This approach avoids the need for traditional recycling methods and allows the plastic to retain its structural integrity.
One example of upcycling corrugated plastic is to cut and reshape the sheets into storage bins or containers. These can be used to organise items at home or in an office, providing an eco-friendly and cost-effective solution for storage needs. Additionally, the ribbed structure of corrugated plastic makes it ideal for creating partitions or dividers within storage spaces.
Another creative way to upcycle corrugated plastic is to use it for signage. The lightweight and sturdy nature of the material makes it perfect for making signs that can be easily mounted on walls or displayed outdoors. With some paint or vinyl lettering, corrugated plastic sheets can be transformed into promotional signs, informational boards, or even artistic displays.
Furthermore, corrugated plastic can be upcycled into reusable packaging. By cutting and folding the sheets, you can create unique and durable boxes or envelopes for gifts, documents, or fragile items. This approach not only reduces waste but also adds a personalised touch to your packaging.
Through upcycling corrugated plastic, we can extend the lifespan of these materials and promote sustainability. By transforming used corrugated plastic into new products, we reduce our reliance on virgin resources and contribute to a more circular economy.

Composite materials: combine with other materials
Corrugated plastic, also known as Coroplast or corrugated polypropylene, can be recycled through various methods. One of the most common methods is mechanical recycling, where the plastic is collected, cleaned, and shredded into small flakes or pellets. These recycled materials can then be used to create new corrugated plastic products or other plastic items.
Another method is chemical recycling, where corrugated plastic undergoes chemical processes to break it down into its constituent molecules. These molecules can then be used as raw materials to create new plastics or other products. Corrugated plastic can also be upcycled into new products without being broken down completely. For example, used corrugated plastic sheets can be repurposed into storage bins, signs, or reusable packaging.
Composite materials are another important aspect of corrugated plastic recycling. This involves combining corrugated plastic with other materials to create composite materials with enhanced properties. By doing so, the recycled corrugated plastic acts as a reinforcing component, improving the strength and performance of the final product. This approach is particularly useful in packaging, signage, and other applications where corrugated plastic is commonly used.
There are several ways to combine corrugated plastic with other materials to create composite materials:
- Mixing: Corrugated plastic flakes or pellets obtained from mechanical recycling can be mixed with other materials, such as recycled plastics or natural fibres. This creates a homogeneous composite material with improved properties.
- Layering: Corrugated plastic sheets can be layered with other materials, such as thin metal sheets or other types of plastic sheets. This creates a laminated composite with enhanced strength and durability.
- Embedding: Corrugated plastic scraps can be embedded into other materials, such as concrete or rubber. This adds reinforcement and improves the impact resistance of the composite material.
- Coating: Corrugated plastic can be coated with other materials, such as resins or polymers, to create a protective layer. This coating can enhance the corrosion resistance, water resistance, or fire retardancy of the final product.
- Sandwich Structures: Corrugated plastic can be used as a core material in sandwich structures, with other materials as the facing sheets. This construction technique is commonly used in lightweight, high-strength composite panels, combining the benefits of different materials.
By combining corrugated plastic with other materials in these ways, it is possible to create a wide range of composite materials with enhanced properties, contributing to sustainability and reducing the environmental impact of plastic waste.

Corrugated cardboard is greener than plastic
Corrugated cardboard is widely considered a greener alternative to plastic. It is made primarily from trees, a renewable resource, and has a high recovery rate of around 90%. In 2018, the corrugated industry recycled 96% of old corrugated containers, compared to only 15% for plastic. Corrugated cardboard is also biodegradable and can be recycled multiple times without losing strength or quality.
On the other hand, corrugated plastic is more durable and moisture-resistant than cardboard, making it reusable and cost-effective. However, the process of fabricating paper from wood uses chlorine-based bleaches, resulting in toxic emissions into the air, water, and soil. Additionally, paper mills are some of the largest consumers of energy and water globally, and it takes about 91% more energy to recycle paper than plastic.
Despite these considerations, the debate about the environmental impact of paper, cardboard, and plastic continues. Some sources suggest that paper and cardboard embody more greenhouse gases than their plastic equivalents over their lifetime. For example, Riverford Organics, a large vegetable box scheme in the UK, has considered switching from cardboard to plastic packaging to reduce its carbon footprint by 70%. However, public perception often views plastic as more harmful to the environment than paper-based products.
To recycle corrugated cardboard, remove additional packaging materials such as foam, plastic wraps, or wood inserts. Cut the packing tape using a box cutter to loosen it, extend the flaps, and press the box flat for easy storage and transportation. Check with your local recycling program to determine if corrugated boxes need to be separated from bottles and cans, and then place them in the correct recycling bin.
Overall, while corrugated plastic has certain advantages, corrugated cardboard is generally considered greener due to its renewability, high recovery rate, biodegradability, and recyclability.
