Acrylonitrile butadiene styrene (ABS) is a popular engineering thermoplastic that is often chosen for its low cost and impact-resistant properties. Due to its relatively low melting point, ABS is easy to melt down and use in injection moulding, making it a versatile material for a wide range of applications. Despite being safe and non-toxic, some of the individual elements of ABS can be potentially dangerous. However, as ABS is non-leaching, there is no way for any of its polymer elements to get into food, water, or soil. As recycled ABS is becoming more popular, here is a guide on how to recycle it.

What You'll Learn
ABS plastic is safe and non-toxic
Acrylonitrile Butadiene Styrene (ABS) is a plastic material used in injection moulding. It is made up of three different materials: acrylonitrile, butadiene, and styrene. This combination makes the plastic very strong with excellent resistance to impacts and other desirable properties.
ABS is non-toxic and odourless, with an opaque, ivory-coloured, granular appearance. It is also free from harmful plasticizers and heavy metals. ABS is "non-leaching", meaning that there is no way for any of the polymer's elements to get into food, water, or soil.
ABS is a thermoplastic with outstanding properties, but its application must be in compliance with safety and environmental standards. It is non-toxic under normal usage conditions and does not contain harmful chemicals like Bisphenol A (BPA) and phthalates. However, it can produce harmful substances when processed or burned, so it is crucial to avoid high-temperature sterilisation methods for products made from ABS material and to follow the relevant usage regulations and standards.
ABS is recyclable and is becoming an increasingly popular material to recycle. The recycling process for ABS is similar to other rigid plastics and is facilitated by its easy melting. Recycled ABS input can be mixed with virgin resin in the manufacturing of new products while retaining product quality.

ABS is recyclable, but not through street-collection programs
Acrylonitrile butadiene styrene, or ABS, is a popular engineering thermoplastic. Its low cost, impact resistance, and low melting point make it a versatile choice for manufacturing. Despite being recyclable, ABS is not typically recycled through street-collection programs.
The recycling process for ABS is similar to that of other rigid plastics. Its low melting point and glass transition temperature make ABS easy to melt down and use in injection moulding. This makes it ideal for a wide range of applications. Recycled ABS can be mixed with virgin resin to create new products without compromising quality.
However, ABS does not have its own unique resin identification number, which is why it is not commonly recycled through street-collection programs. Instead, it is classified under code 7, or "other". This classification may vary depending on the region and the recycling program.
To recycle ABS, it is often necessary to utilise specialised services or programs. Some companies offer ABS recycling services, catering to businesses looking to reduce their environmental impact. These services collect and recycle ABS scrap from various industries, including vacuum forming, signage, and injection moulding. The recycled ABS can then be used in manufacturing, providing a more sustainable alternative to raw ABS.

ABS is popular for its low-cost and impact-resistant properties
Acrylonitrile butadiene styrene, commonly known as ABS, is a popular engineering thermoplastic. Its low cost and impact-resistant properties make it a popular choice for many applications.
ABS is composed of three distinct chemical components: acrylonitrile, butadiene, and styrene. The proportions of these components can vary, but they come together to form a strong and durable polymer. Acrylonitrile contributes to the plastic's chemical resistance, fatigue resistance, hardness, and rigidity, while increasing the heat deflection temperature. Butadiene, a rubbery substance, provides toughness and ductility at low temperatures, although this comes at the cost of heat resistance and rigidity. Styrene gives the plastic a shiny, impervious surface, as well as hardness and rigidity, and it also improves processing ease.
The impact-resistant properties of ABS make it suitable for a wide range of applications. In the automotive industry, for example, ABS is used for both interior and exterior components, such as dashboards, door panels, mirror housings, and bumper bars. Its ability to withstand impact is also why it is often used for protective gear, sports equipment, and helmets. Additionally, ABS is used in the manufacturing of toys and games due to its durability and ability to be moulded into intricate shapes.
ABS is also chosen for its low cost. Recycled ABS, in particular, is becoming an increasingly popular alternative to raw ABS, which can be expensive to use in manufacturing. The recycling process for ABS is similar to other rigid plastics, and its easy melting makes it versatile for a variety of applications.

ABS is lightweight and has high tensile strength
Acrylonitrile Butadiene Styrene (ABS) is a lightweight plastic with high tensile strength. Its tensile strength typically falls between 35 and 60 MPa, indicating its capacity to resist pulling forces without breaking. This property, along with its high impact strength, heat resistance, and rigidity, makes it a popular material in various industries, especially electronics and automobiles.
In the electronics industry, ABS is used for enclosures for electrical and electronic assemblies, such as computer cases. Its excellent electrical insulation and mechanical strength make it ideal for this purpose. Additionally, ABS's ease of processing and ability to be finished in various colours and textures further contribute to its popularity in this sector.
The automobile industry also heavily relies on ABS for parts such as dashboards, bumpers, and interior decorations. Here, its high tensile strength, impact and shock resistance, and rigidity are crucial. The ability of ABS to withstand forces without breaking ensures the safety and durability of these automotive components.
ABS's lightweight nature, combined with its high tensile strength, also extends its applications beyond traditional industries. For instance, it is used in the manufacturing of golf club heads, protective headgear, luggage, and small kitchen appliances. Its strength-to-weight ratio makes it ideal for these products, ensuring they are both lightweight and durable.
Recycling ABS plastic is becoming increasingly popular due to the high cost of raw ABS. The recycling process for ABS is similar to other rigid plastics, and its low melting point makes it easy to melt down and use in injection moulding. This recycled ABS can be mixed with virgin resin to create new products without sacrificing quality.

Recycled ABS can be mixed with virgin resin to create new products
Acrylonitrile butadiene styrene (ABS) is a popular engineering thermoplastic. It is lightweight, rigid, and highly impact-resistant. It is also versatile, with a wide range of applications, including in the automotive, electronics, and consumer goods industries.
ABS plastic is recyclable and can be collected from the vacuum forming, signage, and injection moulding industries. Its low melting point makes it easy to melt down and use in injection moulding, which is why it is often chosen for low-heat applications.
Recycled ABS is becoming an increasingly popular alternative to raw ABS, which can be expensive to manufacture. It is also more environmentally friendly than sending plastic waste to landfills or incinerating it. Recycled ABS can be used in blends with virgin resin to create new products. However, it is important to note that the two phases of ABS and recycled ABS can generate incompatible polymer couples. The recycled ABS resins may undergo degradation, leading to a decrease in molecular weight and mechanical properties. This can be mitigated by adding polymer additives to enhance the strength and toughness of the recycled ABS.
Virgin resin, or plastic resin obtained through the traditional manufacturing method using fossil fuels, is often used in the pharmaceutical industry due to regulatory and safety requirements. However, advanced recycling processes can transform plastic waste into molecular feedstocks to create virgin plastics, providing an eco-friendly alternative.
