Tyre recycling process: stages and machinery

The tyre recycling process transforms a complex, bulky waste stream into distinct fractions that can be reused. To achieve this, tyres arriving at a treatment facility go through different stages of sorting, size reduction, separation and screening.

The exact configuration of a tyre recycling plant depends on the type of input material, the treatment capacity required and the final product to be obtained. Reducing whole tyres to make them easier to handle is not the same as producing a rubber fraction with a controlled particle size.

In this article we explain how tyres are recycled, what happens at each stage and what machinery is involved in an industrial treatment line.

How are tyres recycled?

Tyre recycling generally consists of progressively reducing their size and separating the materials they are made of.

Before mechanical treatment begins, tyres are received, inspected and sorted. Those that cannot be reused or retreaded move on to the treatment lines, where they may undergo primary shredding, steel separation, secondary reduction, fibre separation and size classification.

The goal is to obtain fractions that are as homogeneous as possible and to prepare the material for subsequent recovery or transformation.

In simplified terms, a line can follow this scheme:

Reception and sorting → preparation → primary shredding → steel separation → secondary reduction or granulation → fibre separation → screening and classification.

Stages of the tyre recycling process

1. Reception and sorting of tyres

The process begins with the reception of tyres at the facility.

Before shredding, their condition must be determined and they must be sorted according to their characteristics. Some tyres can follow other recovery routes, while those destined for material recycling move on to the mechanical treatment stages.

Depending on the plant design, this stage may include storage, controlled feeding, pre-cutting or preparation of the tyre before it is fed into the shredder.

Regular feeding is important to maintain a stable flow and avoid overloading the equipment further downstream.

2. Primary shredding

Tyre shredding is one of the most important stages of the process.

Tyres are tough, elastic materials reinforced with metal components. For this reason, the shredding equipment must be able to work with materials that are difficult to tear apart and withstand demanding industrial conditions.

In this first reduction, the whole tyre is transformed into smaller pieces. This makes it easier to transport within the facility and prepares the material for the subsequent separation and reduction stages.

Twin-shaft shredders are one of the technologies used for this type of application, since their counter-rotating rotors are able to grip, cut and tear bulky materials.

At Reverter Industries we work with SatrindTech shredders for tyres, whose configuration must be selected according to input size, treatment throughput and the required result.

3. Steel separation

After the first reduction, separation of the different materials present in the tyre begins.

One of the main fractions is the steel used as structural reinforcement. As these elements are progressively released during shredding, magnetic separation systems can be used to remove them from the material flow.

The efficiency of this stage matters for two reasons: it allows a usable metal fraction to be recovered, and it prevents steel from unnecessarily continuing on to the subsequent reduction and classification equipment.

Depending on the process, separation can be carried out at more than one point in the line to improve the cleanliness of the different fractions.

4. Secondary reduction and granulation

Once the first shredding has taken place and part of the metal elements have been removed, the material can move on to a second reduction stage.

The goal is to progressively reduce the size of the rubber until the particle size required by the process is reached.

Depending on the desired final product, secondary shredders, granulators or other reduction equipment can be used. This stage must be sized taking into account the feed capacity, the size of the pieces coming from primary shredding and the required output size.

The smaller and more homogeneous the final fraction needs to be, the more important it becomes to correctly control the different reduction stages.

5. Textile fibre separation

Besides rubber and steel, tyres contain textile materials that must be separated during the recycling process.

After the reduction stages, these fibres become more exposed and can be extracted using specific separation and extraction systems.

Correctly removing the textile fraction helps improve the purity of the recovered rubber and eases subsequent classification operations.

The technology used will depend on the design of the facility and the quality requirements of the final product.

6. Screening and classification by particle size

The last part of the mechanical process consists of classifying the material according to the size obtained.

Screening systems make it possible to separate different particle sizes and return to the circuit any particles that still need further reduction.

This recirculation system helps achieve a more uniform final product and allows the process to be adjusted to different output requirements.

Tyre recycling, therefore, does not depend on the shredder alone. It is the result of the coordinated combination of feeding, shredding, separation, conveying and classification equipment.

What machinery is used to recycle tyres?

A tyre recycling line can incorporate different equipment depending on the capacity required and the final product.

Process stage	Typical machinery	Main function
Reception and feeding	Hoppers, dosers and conveyors	Regulate the input of material
Preparation	Cutting or pre-preparation equipment, depending on the process	Ease subsequent treatment
Primary shredding	Industrial shredder	Reduce the whole tyre into manageable pieces
Metal separation	Magnetic separators	Recover steel and remove metals from the flow
Secondary reduction	Secondary shredders or granulators	Progressively reduce the size of the rubber
Fibre separation	Extraction or separation systems	Remove textile components
Classification	Screens	Separate the material by particle size
Internal conveying	Belts and conveyors	Connect the different stages of the line

Choosing the tyre recycling machinery must be done as a whole. Correctly sizing a shredder but not the feeding, conveying or classification systems can limit the capacity of the entire facility.

For this reason, in industrial projects it is advisable to study the complete process rather than each piece of equipment in isolation. You can browse our range of recycling machinery to learn about the different technologies that can be integrated into a treatment line.

What materials are obtained from tyre recycling?

Mechanical treatment mainly separates three major fractions: rubber, steel and textile materials.

Recycled rubber

Rubber represents the main fraction sought for recovery.

Depending on the reduction and classification stages, it can be obtained in different sizes, from shredded pieces to rubber granulate with a finer particle size.

The final use determines the level of reduction, cleanliness and homogeneity required. That is why, before designing a facility, it is important to define which product is to be obtained.

Recovered steel

The metal elements built into tyres can be separated using magnetic systems as they are released during shredding.

The goal is to obtain a metal fraction separated from the rubber and prevent it from continuing on to the subsequent stages.

Textile fibre

The textile fraction is progressively released during the shredding and granulation stages.

Separation systems make it possible to remove it from the rubber to improve the quality of the fractions obtained and to ease their subsequent management or recovery.

How is a tyre recycling plant designed?

There is no single configuration valid for every facility.

The design of a tyre recycling plant must start from the actual characteristics of the project. Before selecting machinery, it is advisable to define at least:

Type and dimensions of the tyres to be received.
Treatment capacity required.
Planned operating hours.
Maximum input size.
Desired final particle size or size.
Purity required for the recovered fractions.
Feeding system.
Need for material recirculation.
Separation equipment required.
Available space and plant layout.
Level of automation.
Conveying equipment between processes.

A machine’s nominal capacity alone does not determine the actual output of a line. The facility must be balanced so that the different stages can work continuously and in a coordinated way.

At Reverter Industries we design and integrate recycling plants adapted to the characteristics of the waste and the needs of each project.

The role of the shredder in a tyre recycling line

The shredder shapes much of how the subsequent stages perform.

Its job is not just to reduce the volume of the tyre. Cutting geometry, output size, treatment capacity and feeding regularity all directly influence the downstream separation and reduction processes.

To select a piece of equipment, variables such as the following must be analysed:

Tyre dimensions.
Material composition.
Input size.
Required output.
Target output size.
Cutting technology.
Blade configuration and thickness.
Installed power.
Equipment located before and after the shredder.

Within the SatrindTech range, models such as the K30 cover tyre applications. The final selection, however, must be made based on the actual working conditions and the line as a whole.

If you want to compare different reduction technologies for other waste streams and applications, also check our range of industrial recycling shredders.

Recycling and management of end-of-life tyres

The industrial recycling process is only one part of managing tyres at the end of their useful life.

Before treatment, aspects such as collection, sorting, traceability, reuse, retreading and delivery to authorised operators and facilities must be considered.

In this article we have focused specifically on the technical side of the treatment and the machinery needed to transform the material.

To learn more about the regulations, obligations and management of end-of-life tyres, you can read our guide on environmental management of tyres.

Frequently asked questions about tyre recycling

How are used tyres recycled?

Tyres destined for recycling are sorted and go through different reduction and separation stages. The process typically includes primary shredding, steel separation, secondary reduction, textile fibre separation and screening by size.

What machinery is needed to recycle tyres?

It depends on the final product and the capacity of the facility. A line can integrate feeding systems, industrial shredders, magnetic separators, secondary reduction or granulation equipment, fibre separation systems, screens and conveyors.

Why are tyres shredded?

Shredding reduces the size and volume of the tyre, progressively releases the different materials it is made of, and prepares the waste for the subsequent stages of separation, classification and recovery.

What materials can be recovered from a tyre?

Mechanical treatment mainly separates rubber, steel and textile materials. The degree of cleanliness and the size of the fractions depend on the configuration of the line and the treatment stages installed.

What is the difference between shredding and granulating tyres?

Shredding carries out an initial or intermediate reduction of the tyre’s size. Granulation corresponds to a more advanced reduction stage aimed at obtaining smaller particles with a more controlled particle size.

Are all end-of-life tyres shredded?

Not necessarily. Before recycling, tyres must be sorted. Some can be directed to other recovery routes when their condition allows it, while those destined for material recycling move on to the corresponding mechanical treatment processes.

A recycling line must be designed as a complete process

The tyre recycling process combines several technologies that must work in a coordinated way. Shredding is essential, but its performance depends on how feeding, separation, secondary reduction, conveying and screening are integrated.

For this reason, the design of a facility must start with the waste to be treated and the product to be obtained. From this information it is possible to define the technology and correctly size each stage.

At Reverter Industries we study every project to select and integrate the most suitable recycling machinery for the process.

How scrap metal is recycled: process, stages, benefits

Scrap metal is recycled in five stages: collection and traceability, inspection and sorting, magnetic and eddy-current separation, shredding and screening, and smelting to produce new metal. The process separates ferrous metals (iron, steel) from non-ferrous ones (aluminium, copper) and returns them to the production cycle with the same quality as virgin raw material.

Unlike other materials, metals can be recycled infinitely without losing their physical or chemical properties. That makes scrap a strategic resource that sustains entire industries —from steelmaking to the automotive sector— reducing dependence on primary mining.

Summary table: stages of scrap metal recycling

Stage	What happens	Key technology
1. Collection	Extraction, transport and weighing of the material	Reverse logistics, legal documentation
2. Sorting	Inspection and assessment of metal quality	Visual inspection, appraisal
3. Separation	Splitting ferrous and non-ferrous	Magnets, eddy currents, spectrometry
4. Shredding	Volume reduction and screening by size	Twin-shaft shredders, screens
5. Smelting	Melting the clean metal into ingots	Furnaces, briquetting

Why is recycling scrap metal important?

Scrap metal recycling is a pillar of the circular economy because of its environmental and economic impact:

Massive energy savings: producing aluminium from scrap requires 95% less energy than producing it from virgin bauxite. Recycling steel consumes less than 40% of the energy needed to make new steel.
Lower emissions: manufacturing with recycled material can cut CO₂ emissions by up to 20%, which is key to global climate targets.
Less mining: it avoids one of the most destructive activities for the ecosystem —soil erosion and biodiversity loss— and preserves finite deposits.
Stable supply: an estimated 40% of the world’s steel comes from recycled scrap.

Types of recyclable metals

Ferrous metals: steel and cast iron

They contain iron as their base element and include steel and cast iron. Their magnetic property greatly simplifies their separation during the process. Since steel is one of the most widely used materials in construction, managing it is critical to maintaining industrial supply.

Non-ferrous metals: aluminium, copper, nickel, tin and zinc

They contain no iron. They represent a smaller volume but greater economic value. Their demand in electronics and high technology stems from properties such as electrical conductivity or corrosion resistance. Nickel and zinc are essential in alloys that require durability under extreme conditions.

The 5 stages of the scrap metal recycling process

1. Collection, transport and traceability

The cycle begins with the extraction of the material from industrial dismantling operations or urban collection points. Specialised vehicles transport it to the plant. The initial weighing and legal documentation are essential: they ensure regulatory compliance and set the real economic value of the incoming batch. Good segregation at source reduces later costs.

2. Inspection and sorting at the plant

The materials undergo rigorous inspection. Appraisers identify contaminants and assess the quality of the metal in order to determine its destination in the production chain.

3. Separation of ferrous and non-ferrous

Here technology is decisive:

Magnetic separation: high-power magnets extract iron and steel.
Eddy currents: they repel conductive non-ferrous metals such as aluminium, separating them from plastics.
Spectrometry: it identifies specific alloys in real time, allowing sorting to a very high degree of purity and maximising market value.

4. Shredding and screening

Industrial shredders reduce the size of bulky pieces such as car bodies. Twin-shaft shredders are ideal for metals and hard scrap thanks to their high torque and low energy consumption. Screening then separates the particles by size, and non-metallic components (plastics, textiles) are removed to prevent contamination of the final ingots.

5. Smelting and preparation

The clean, homogeneous material is melted down to return to the production chain. In the case of turnings and material that burns off excessively, briquetting compacts the metal and makes it possible to recover oils, coolants and emulsions, increasing resale value.

Handling specific types of scrap

Not all metal waste is processed the same way. Each stream requires differentiated techniques according to its origin and composition.

Electronic waste (WEEE)

Electrical and electronic devices are a challenge because of their technical complexity: they mix materials that must be separated with precision.

Precious metals: phones and circuit boards hold small but valuable amounts of gold, silver and copper, which are isolated from the plastic and ceramic matrix through specialised processes.
Hazardous waste: some components contain toxic substances that are managed under strict protocols to prevent contaminants from leaching into soil or water.

Industrial and demolition scrap

Dismantling warehouses or buildings generates beams and heavy structures that require robust machinery capable of cutting and breaking them up before sorting. The resulting mix contains various steels and alloys that are separated with magnets and eddy currents so that each fraction reaches the smelter with the necessary purity.

Packaging and cans

Drink and food cans form a steady, homogeneous stream with excellent recycling opportunities. Aluminium keeps its properties after multiple cycles and saves enormous amounts of energy compared with primary production. Before melting it, it is vital to remove leftover contents, labels and impurities through washing and drying, guaranteeing a flawless secondary metal.

Frequently asked questions about scrap metal recycling

What are the stages of scrap metal recycling?

Five: collection and traceability, inspection and sorting, separation of ferrous and non-ferrous, shredding and screening, and smelting. Each stage prepares the metal to return to the production chain with maximum purity.

How are ferrous metals separated from non-ferrous ones?

Ferrous metals (iron, steel) are extracted with high-power magnets thanks to their magnetic property. Conductive non-ferrous metals, such as aluminium, are separated with eddy currents. Spectrometry refines the sorting by identifying specific alloys.

How much energy does recycling scrap metal save?

Producing aluminium from scrap requires 95% less energy than from virgin bauxite, and recycling steel consumes less than 40% of the energy needed to make it new. This drastically reduces greenhouse gas emissions.

What machinery is needed to recycle scrap metal?

Twin-shaft shredders for hard metals, magnetic separators for ferrous metals, eddy-current separators for non-ferrous metals, screens to sort by size and conveyor belts to move the material between stages.

Does scrap metal lose quality when recycled?

No. Metals can be recycled infinitely without losing their physical or chemical properties, which makes them an ideal raw material for the circular economy.

Optimise your metal recycling process

Recycling scrap metal profitably depends on having the right machinery at every stage. Discover our industrial shredders and scrap metal shredders, or ask our team how to design a complete recycling machinery line tailored to your plant.

Waste Management Regulations: Keys to a Circular Economy in Spain

Waste management regulations in Spain are essential to ensure sustainable waste management and reduce environmental impact. These regulations establish measures for waste collection, treatment, recycling, and recovery, while also promoting the development of the circular economy and environmental protection.

Regulatory Framework for Waste Management

Spanish waste legislation is based on national, regional, and European regulations. Among the most important are the Waste Legislative Royal Decree and the State Framework Waste Management Plan, which establish objectives for prevention, recycling, and reducing the amount of waste sent to landfill.

In addition, Spain’s autonomous communities develop specific regulations adapted to the needs of each territory, coordinating with local authorities to improve management efficiency. European Union directives also play a key role, especially in promoting the circular economy and ecological transition.

Types of Waste and Specific Regulations

The regulations distinguish different types of waste according to their hazardous nature and origin. The most important categories include:

Hazardous waste, which requires strict controls for storage, transport, and disposal.
Municipal and non-hazardous waste, managed through selective collection and recycling systems.
Industrial and construction waste, subject to specific treatment plans.
Waste electrical and electronic equipment (WEEE), regulated through extended producer responsibility systems.

Each category has specific protocols to minimize environmental risks and improve material recovery.

Extended Producer Responsibility

One of the pillars of current regulations is extended producer responsibility. This system requires manufacturers and distributors to take responsibility for managing the waste generated by their products at the end of their useful life.

This particularly affects sectors such as:

Packaging and plastic products.
Electrical and electronic equipment.
Tires and other special waste.

To comply with these obligations, many companies participate in collective collection and recycling systems that allow waste to be managed more efficiently and sustainably.

Waste Collection and Treatment Operations

Waste management includes several key stages:

Collection and transport.
Classification and storage.
Recycling and recovery treatments.
Controlled disposal.

Among the most common treatments are material recycling, composting of organic waste, energy recovery, and in some cases, controlled incineration or disposal in authorized landfills.

Treatment facilities must comply with very strict technical and environmental requirements to ensure safety and minimize polluting emissions.

Waste Prevention and Circular Economy

Current regulations prioritize waste prevention over disposal. To achieve this, measures are promoted such as:

Reducing the use of single-use plastics.
Encouraging product reuse and repair.
Implementing separate collection systems.
Developing recyclable packaging and eco-design strategies.

The goal is to reduce waste generation and keep materials within the production cycle for as long as possible, thereby promoting the circular economy.

Environmental Protection and Administrative Control

The legislation also establishes control mechanisms to protect the environment and public health. These include:

Regulation of contaminated soils.
Environmental inspection and monitoring systems.
Waste registration and traceability.
Control of emissions and polluting activities.

Authorized companies and waste managers must comply with registration, reporting, and waste tracking obligations to ensure safe and transparent management.

Future Challenges in Waste Management

Among the main challenges are the increase in waste resulting from urban growth and consumption, as well as the need to modernize infrastructure and recycling systems.

Plastics Recycling Processes: A Guide to a Sustainable Future

Recycling plastics is a crucial activity for environmental sustainability and the circular economy. As everyday life produces large amounts of plastic waste, it is essential to understand the processes involved in its transformation and reuse.

This comprehensive guide explores the key steps in plastics recycling, the different types of materials, and their impact on the environment. Through education and awareness, we can contribute to a more sustainable and responsible future.

Key processes in plastics recycling

Recycling plastics is an essential process for waste management in an increasingly sustainability-conscious world. Not only does this process reduce the amount of plastics that end up in landfills and oceans, but it also encourages the circular economy, where materials are reused instead of being discarded. The key processes in plastics recycling are described below.

Collection and sorting of plastic packaging

The first stage of plastic recycling begins with the collection of discarded packaging in homes and workplaces. It is essential that citizens properly separate plastic containers in the yellow container, which is specifically designated for this type of waste. A correct initial classification facilitates the subsequent process, since plastics can be mixed with other materials, which would complicate their recycling.

Once the plastic containers are deposited in the yellow container, they are transported to recycling plants where they are sorted. In these facilities, a distinction is made between plastics, metals and bricks, thanks to an automated process that uses advanced technology. The purity of the materials is crucial, as it determines the quality of the recycled plastic that will ultimately be obtained. A good level of separation is essential to ensure that recycled plastics are suitable for the manufacture of new products.

Sorting and separation in specialized plants

The next phase in plastics recycling takes place in sorting plants, where a more detailed process is carried out. These plants are equipped with technology that allows for a precise selection of different types of plastics. This step is key, as plastics have diverse properties and chemical compositions that require specific procedures for processing.

In Spain, Ecoembes manages a network of 97 sorting plants. There, plastic packaging is classified into categories that include PET (polyethylene terephthalate), HDPE (high-density polyethylene), PVC (polyvinyl chloride) and polypropylene (PP), among others. Thanks to this type of sorting, the recycling process is optimized, ensuring that each type of plastic is treated with the most appropriate method to maximize its recovery and reduce pollution in recycling.

Transformation of plastics into recycled raw material

Once the plastic packaging has been sorted and sorted, the next step is its transformation into recycled raw material. The plastics are grouped into bales and sent to approved recyclers, who are entities specialized in the processing of these materials. This process involves various treatment techniques, which usually include washing and crushing.

In the case of PET, commonly used in bottles, it undergoes rigorous washing to remove impurities, followed by a crushing process in which it is converted into small chips. These chips are the ones that will be used to manufacture new packaging or even textile fibers. HDPE, on the other hand, also goes through a similar wash and is transformed into pellets that can be used to produce new products, such as pipes or containers.

In summary, plastic recycling is a complex process that begins with the collection and sorting of packaging and culminates in the transformation of these into recycled raw materials. Each stage is critical to ensure that effective recycling is achieved that contributes to a more sustainable future.

Types of plastics and their specific recycling methods

Recycling plastics is a process that varies significantly depending on the type of material used. Knowing the particularities of each plastic is essential to optimize its recovery and recycling. This section will address the specific recycling methods of the most common plastics, such as PET, HDPE, as well as the challenges associated with PVC and polypropylene.

PET recycling: washing and shredding

Polyethylene terephthalate (PET) is one of the most recycled plastics in the world, mainly used in beverage bottles. The recycling process begins with the collection of PET containers, which are then transported to recycling plants. There, an exhaustive washing and crushing process is carried out.

In the washing phase, the containers are purified to remove contaminants such as labels and content residues. The clean PET is then shredded into small pieces, known as chips or flakes. These flakes are the ones that will be used as raw material for the manufacture of new products, including bottles, textiles, and other packaging.

HDPE Recycling: Processes and Applications

High-density polyethylene (HDPE) is another commonly recycled plastic, prevalent in cleaning products and food packaging. Like PET, the HDPE recycling process includes washing and transformation stages. HDPE containers are sorted and cleaned to remove impurities.

Once cleaned, the HDPE is crushed and turned into pellets. These granules have very diverse applications, allowing the manufacture of new products such as containers, pipes and toys. The versatility of recycled HDPE makes it a highly valued material, thus contributing to the circular economy.

PVC and polypropylene recycling: challenges and solutions

Recycling other types of plastics, such as polyvinyl chloride (PVC) and polypropylene (PP), presents several challenges. Both plastics are less common in the recycling cycle, in part due to the complexity of their composition and the risks associated with their processing.

Purification requirements: PVC, for example, can release toxic substances during recycling, requiring more careful processes.

Limitations in mechanical recycling: Polypropylene, although recyclable, is not always accepted in recycling plants due to its low demand on the secondary market.

Technological innovations: New chemical recycling technologies are being developed to address these limitations, allowing these plastics to break down into their building blocks.

With the development of better methods and technologies, it is possible to increase the recycling rate of these plastics and minimize their environmental impact, contributing to a more sustainable future.

Impact and management of plastics recycling

Recycling plastics has a significant impact on both an environmental and economic level. Proper management of plastic waste not only contributes to the reduction of environmental impact, but also offers opportunities to strengthen the circular economy. Through a comprehensive approach to recycling management, it is possible to maximize the benefits derived from this crucial process.

Environmental and economic benefits of recycling

Plastic recycling is presented as an effective solution to mitigate various environmental problems. First, it helps reduce the amount of waste sent to landfills, which in turn decreases soil and water pollution. By recycling plastics, the generation of new materials from virgin resources is avoided, which translates into lower energy consumption and a reduction in greenhouse gas emissions.

From an economic point of view, plastics recycling not only creates jobs in the waste management and recycling sector, but also promotes innovation in the production of new materials and products. The integration of recycled plastics in the manufacture of products, such as new packaging and textile fibres, boosts the competitiveness of companies by offering more sustainable alternatives to consumers.

Education and public awareness for responsible recycling

Education and awareness are fundamental pillars in the management of plastic recycling. Ecoembes and other organisations work to provide information and resources that help citizens understand the importance of correctly separating waste and contributing to the recycling process. Awareness programs promote sustainable practices in the home, thus encouraging responsible behavior that positively impacts the environment.

The formation of a culture of recycling among the population allows not only to improve the recovery rates of materials, but also to generate a sense of shared responsibility in the fight against plastic pollution. A comprehensive educational approach can lead to greater citizen participation and more effective waste management, benefiting both the environment and the local economy.
