Tyre Pyrolysis Recycling presents a promising solution to environmental challenges posed by discarded tires, offering opportunities for sustainable resource management and energy recovery. With India's burgeoning waste tire problem, establishing a Tyre Pyrolysis Recycling facility not only contributes to environmental conservation but also presents a lucrative business opportunity.

Economic Growth and Tire Production: India's tire and recycling sector are witnessing significant growth, with tire production rising alongside economic expansion. This growth underscores the importance of recycling end-of-life tires, especially as the local tire industry grows at a rate of 12% per year.

Potential Growth: The global tire recycling market is experiencing steady growth, with a Compound Annual Growth Rate (CAGR) of 3.3% projected over 2022-2032. The Indian tire and rubber recycling industry have the potential to reach INR 350 Billion in the next five to ten years, driven by the growing domestic automobile industry.

Government Initiatives: The government is increasingly prioritizing sustainable growth, with initiatives aimed at fostering the tire recycling sector. Niti Aayog's comprehensive study on tire recycling and its subsequent recommendations exemplify this commitment.

Tire Pyrolysis Sector: The tire pyrolysis sector in India recycles 1.3 million tons of tires annually, producing almost half a million tons of fuel oil. This sector offers opportunities to collaborate with tire producers for value addition.

Extended Producer Responsibility (EPR): The Ministry of Environment, Forest & Climate Change (MoEF & CC), in collaboration with the Central Pollution Control Board (CPCB), has drafted the Tyre Recycling EPR policy, signaling a proactive approach to waste management and environmental stewardship.

PYROLYSIS PLANTS

Pyrolysis plants can be classified into several types based on the operational method and the scale of operation. Here are some common types:

1. Batch Pyrolysis Plants: These plants operate in batches, meaning they process one batch of material at a time. Once a batch is completed, the plant is cooled down, the end products are removed, and a new batch is introduced.

2. Continuous Pyrolysis Plants: These plants operate continuously, with raw materials being fed into the plant and end products being removed simultaneously. This type of plant is typically used for large-scale operations.

3. Conventional/Slow Pyrolysis Plants: These plants operate at a slow heating rate and low temperature ranges, producing tar and char as the main products.

4. Fast Pyrolysis Plants: These plants operate at high temperatures and rapid heating rates, commonly used to produce bio-oil and gas.

5. Ultra-Fast/Flash Pyrolysis Plants: These plants operate at very rapid heating rates and temperatures, producing gas and tar in fewer amounts compared to slow pyrolysis.

Each type of pyrolysis plant has its own advantages and is used for different applications. The choice of plant type depends on the desired end product and the characteristics of the feedstock. However, in India, within the pyrolysis method, there are two main types of plant setups that are used:

• 1. Batch pyrolysis plants
• 2. Continuous pyrolysis plants

Both batch and continuous pyrolysis processes produce the same final product. Most tire pyrolysis units in India use batch processes. These units vary in their process control, safety features, raw materials, finished products, and waste handling methods.

The Central Pollution Control Board (CPCB) mandates that only Advanced Batch Automated Process (ABAP) type tyre pyrolysis oil Units are permitted for standardizing batch pyrolysis operations

FINAL PRODUCT

In tire pyrolysis, the products generated are:

• 1. Pyro Gas: It's a combustible gas made up of various components. Hydrocarbon gas can be cleaned in a wet scrubber system to make harmless smoke for release into the atmosphere, or it can be reused for heating within the facility.
• 2. Pyro Oil: This is a liquid product that can range from valuable fuel oil to less valuable blend stock. The oil, mixed with light diesel oil, can be utilized in various industries such as boiler companies, rolling mills, casting industries, asphalt plants, and more.
• 3. Char: It's a solid residue containing carbon, silica, and other materials. Utilized in ink or cement sectors.
• 4. Steel: Thin wire from tires, sold as scrap steel.

RAW MATERIAL

According to the SoP published by the MoEF & CC, the raw material that the plant may use can be only indigenous generated waste tyre, that is, waste tyres generated within India only.

Raw materials for tire recycling business include:

• 1. Used or waste tires (Radial or Nylon)
• 2. Shoe soles
• 3. Waste conveyor belts
• 4. Coal for generating heat in the pyrolysis plant

GOVERNMENT POLICIES, PROGRAMS & FINANCIAL ASSISTANCE

1. Government Policies:
The Ministry of Environment, Forests, and Climate Change has introduced a draft notification outlining regulations for Extended Producer Responsibility (EPR) regarding waste tires. This policy expands the responsibility of producers or importers to include the disposal of waste tires. EPR obligations for 2022-23 are set at 35% of the quantity of new tires manufactured or imported in 2020-21, increasing to 70% in 2023-24 and reaching 100% by 2024-25 based on the quantity of new tires produced or imported in preceding years.

2. Financial Assistance:
For small-scale plants requiring an investment of approximately 20 to 25 lakhs, entrepreneurs can avail loans through the Pradhan Mantri Employment Generation scheme. As a recycling project, borrowers may secure up to 90% of their investment as a loan along with a subsidy of up to 15%. Additionally, the Ministry of Micro, Small & Medium Enterprises (MSME) in India provides various schemes and benefits tailored for businesses operating in the waste tire recycling sector.

3. Innovation Support:
The Union Ministry for MSMEs has initiated a scheme offering financial support of Rs 15 lakh and access to incubator facilities for aspiring entrepreneurs with innovative solutions, particularly in focus areas such as water and waste management.

ECOLOGICAL IMPACT:

I. Tyre Pyrolysis Waste:

Gas Emissions: During tyre pyrolysis, two types of waste gases are produced. The first is tail gas from the pyrolysis reactor, and the second is exhaust gas from heating the reactor. The first type, a non-condensing but combustible gas, is reused to heat the reactor. The second type undergoes purification through a flue gas system, including a tower for desulfurization and purification, a dust collector, and a water scrubber.

Wastewater: All water used in the tyre pyrolysis facility is recycled, with no discharge of wastewater.

Solid Waste: Carbon black is the residue left in the pyrolysis reactor, generated as a by-product. It can be sold directly, compressed into briquettes for fuel, or ground into powder for pigment production.

II. Environmental Impact of Tyre Pyrolysis Plants:

Production Concerns: Incomplete pyrolysis can lead to harmful substances if gas treatment is inadequate. Proper control measures prevent these substances from being released.

Gas Recycling: Recycling syngas is crucial to minimize fuel consumption and environmental impact. Failure to recycle can contribute to pollution and climate change.

Oxygen Levels: High oxygen levels during pyrolysis can lead to combustion instead of proper pyrolysis. Efficient energy recovery offsets emissions.

Explosion Risk: Safety features are necessary to prevent explosions due to oxygen bursts or defects.

CONCLUSION

With the rapid increase in the number of cars in India, the demand for tires has also risen. However, as each tire eventually becomes waste, recycling them has become crucial to address environmental and resource challenges. India generates around 0.6 million tons of tire scrap yearly, mainly due to the growing vehicle population.

Efforts like mandating the scrapping of old vehicles and the rise of organized players are expected to increase the availability of scrap tires. Stockpiled tires pose environmental and health hazards, but technologies like Gasification and Pyrolysis offer promising solutions. Pyrolysis, for instance, can turn tires into useful products like fuel oil, carbon black, and steel wires.

This technology, though faced with technical and economic challenges, is becoming more feasible. For instance, from 1000 kgs of waste tire input, around 450 liters of industrial fuel oil, 125 kgs of petroleum gas, 330 kgs of carbon black, and up to 110 kgs of steel wires can be produced.

The economics of tire reprocessing units are attractive, with profitability determined by factors like tipping fees, revenue from product sales, processing costs, and disposal costs. The initial investment for a small pyrolysis unit ranges from Rs 3.5 to 4.0 crores, increasing with capacity.

Maximizing the use of tires through technologies like pyrolysis can reduce environmental impact and conserve natural resources. While tire management remains a growing problem, pyrolysis offers a potential solution by converting tire waste into marketable products, thus addressing the tire disposal challenge in the years ahead.
