Secondary recycling is a waste management
process that recovers valuable components of waste to transform them into
reusable solutions. It helps reduce the demand for virgin resources, minimises
landfill space and promotes the re-utilisation of waste.
In this article, we’ll outline what
secondary recycling is and how this process can become a standard practice in
society. It is able to be applied to various different materials and
contributes to a more sustainable and circular economy.
At Gradeall, we are innovators of waste
management solutions, we seek to transform the waste management process by
building industry-leading machinery for pursuing recycling methods. If you

Secondary recycling, also known as
mechanical recycling or physical recycling, is a process of recycling waste
materials by converting them into a new product or raw material with similar or
lesser quality compared to the original material.
Secondary recycling can be applied to
various materials. Some common materials that can undergo secondary recycling
waste can be mechanically processed to produce recycled plastic pellets, which
can then be used as raw materials in the manufacturing of new plastic products.
Used paper and cardboard can be collected,
sorted, and processed to create recycled paper and cardboard products, such as
packaging materials, paperboard, or tissue products.
At Gradeall, we manufacture balers for collecting paper and cardboard waste, helping to streamline this first step in secondary recycling.
Glass waste can be crushed, sorted by
colour, and melted to produce new glass products, such as bottles, jars, or
glass fibre for insulation.
At Gradeall, we have developed an
industrial Glass Crusher that is the ideal first step in
secondary recycling for glass.
Various metals, including aluminium, steel,
copper, and others, can undergo secondary recycling. Metal waste is often
melted and purified to obtain recycled metal, which can be used in the
production of new metal products.
Textile waste, including clothing and
fabrics, can be mechanically processed to create recycled fibres. These fibres
can then be used to manufacture new textiles or incorporated into other
products like insulation materials or automotive components.
Secondary recycling methods are applied to
electronic waste to recover valuable materials, such as metals, plastics, and
precious metals. These materials can be reused in the production of new
electronic devices or other products.
Used tires can be processed through
secondary recycling methods, such as shredding and grinding to produce a crumb
rubber, which is then used in creating new materials. This is a great way to
deal with an otherwise non-biodegradable type of waste.
It’s important to note that the feasibility
and effectiveness of secondary recycling may vary depending on factors such as
the type of material, its composition, and the availability of suitable
Additionally, certain materials may require
specific processes, such as chemical recycling or advanced recycling
techniques, for optimal recycling outcomes.
In the context of waste tires, secondary
recycling refers to the process of converting used tires into new products or
materials through mechanical means. Here are some common methods used in
secondary tire recycling:
Waste tires can be turned into crumb
rubber, using a technique such as granulation or cryogenic grinding. This crumb
is then used in the production of playground surfaces, road asphalt and sports
Crumb rubber can also be mixed with other
additives, such as binders and chemicals, to create new rubber products. The
mixture can be moulded into various shapes or used as an ingredient in the
production of rubber-based products, such as flooring, mats or automotive
Pyrolysis is a thermal decomposition
process where tires are heated in the absence of oxygen, breaking them down
into liquid fuels, gases, and solid char. The liquid and gas products can be
used as fuel or chemical feedstock, while the solid char can be used as a
carbon black substitute.
The use of tires as fuel, also known as tire-derived fuel (TDF), is not typically considered secondary recycling. Instead, it falls under the category of energy recovery or thermal recycling.
Tire-derived fuel involves using shredded
or whole tires as a fuel source in industrial processes, such as cement kilns,
pulp and paper mills, or power plants. Tires have a high energy content, and
burning them as fuel can provide heat or generate electricity.
While tire-derived fuel can be an effective
means of utilising the energy content of waste tires and reducing reliance on
fossil fuels, it is not considered secondary recycling because the tires are
not transformed into new products or materials. Instead, they are used as a
direct energy source.
At Gradeall, we manufacture
industry-leading machinery that contributes towards the tire recycling
industry. We help tire handlers efficiently manage this type of waste so that
tire recycling methods are accessible and convenient for businesses to pursue.
Tire balers aid businesses in transporting
waste tires to recycling centres. By compacting tire waste into tight and
secure bales, businesses can transport more of them at once, which saves costs
on transport and reduces the amount of fuel used.
The Gradeall Tire Balers include the MK2,
and the Truck Tire Baler. Each tire baler has been
designed to meet various demands and tire types. If you’re unsure of which tire
baler would be most beneficial for your business, get in touch
with us for an expert opinion.
Removing the sidewalls from tires aids in
preparing them for further recycling methods. The Car Tire Sidewall Cutter is able to complete
this in just under 20 seconds and it can handle from 120-140 tires per hour.
At Gradeall, we are committed to pursuing
tire recycling methods with industry-leading machinery. Check out our full
range of tire recycling machines, or alternatively, give us a call
to discuss your operational needs.
