Converting waste tyres to oil is now a highly effective technique for solving the difficulties that waste tyres cause. This is also true in relation to the vitality crisis which we are currently facing.
The tyre-to-oil process involves pyrolysis, and also this technique demands a high temperature. Before using one of those plants to convert waste tyres into oil, here are some considerations you need to be aware of:
- First thing that is essential is to extract the steel wire out of the tyres
- Another consideration is so that the waste tyre sizes can reach a certain standard. For continuous and semi-continuous waste tyre-to-oil equipment, the size has to be around 50mm. To the batch pyrolysis plants, the size and style needs to be below 1,200mm.
From this point, the recycling technique of turning tyres into oil may start:
- The waste tyres are placed inside a reactor
- The reactor is heated by using fuels such as charcoal, coal, wood, or fuel gas. After the temperature has reached about 120 degrees, the burning process produces oil gas
- Several of the oil gas will flow into a condensing system where it makes liquid oil. The gas that cannot liquify under this pressure will pass back in a combustion system after it provides passed through the purification system. This gas will then be used being a fuel to provide heat towards the reactor, which helps to conserve energy
- After the oil-production process completes, the reactor is going to be cooled down. In this step of your process carbon black is produced
- There exists a additionally a dedusting system which is used to process any smoke and to make sure that the machinery fails to produce air pollution
When the tyre-to-oil process completes, you happen to be left with around 45% fuel oil, 8% combustible gas, 12% steel wire, and 35% carbon black. Every one of these end-goods are useful and can be used for various applications:
- Fuel oil is commonly used as the industrial fuel materials or it is actually refined further into diesel
- The carbon black can also be used as a kind of fuel or it could be processed further
- The steel wire is either recycled or resold to steel plants for producing new items
- The combustible gas is also recycled and employed to provide fuel for the reactor, which will help to save lots of energy through the entire working process

Tire pyrolysis has emerged as a promising solution for both the disposal of waste tires and the production of valuable by-products. As the global demand for sustainable waste management and energy production grows, pyrolysis plants offer an innovative approach to transforming waste tires into useful products, including fuel oil, carbon black, and steel wire. However, the profitability of tire pyrolysis projects depends on various factors that influence operational costs, product yields, and market demand. Revenue Streams from Tire Pyrolysis Tire pyrolysis plants operate by heating waste tires in the absence of oxygen, causing them to decompose into several products, primarily oil, gas, and carbon black. The resulting products can be sold for various industrial applications, creating multiple revenue streams. The profitability of a tyre pyrolysis plant largely hinges on the market demand for these products. Fuel Oil The primary product generated from tire pyrolysis is fuel oil, which can be used as an alternative to traditional fuels such as diesel or furnace oil. This fuel oil has a high calorific value and is used in industries such as cement, brick manufacturing, and power generation. The demand for low-cost, alternative energy sources continues to rise, particularly in regions facing energy shortages or those striving to reduce reliance on fossil fuels. As a result, tire-derived fuel oil has become a valuable commodity, contributing significantly to the profitability of pyrolysis projects. Carbon Black Another key by-product of tire pyrolysis is carbon black, a material used extensively in the production of rubber, plastics, and batteries. The demand for carbon black has surged in recent years, driven by its use in the automotive and electronics industries. As the global automotive market grows, particularly in developing economies, the demand for high-quality carbon black is expected to continue its upward trajectory. By optimizing the pyrolysis process to produce high-grade carbon black, tire pyrolysis plants can generate substantial revenue from this product. Steel Wire Tire pyrolysis plants also recover steel wire from the tires during the process. Although the value of steel wire is lower compared to fuel oil and carbon black, it is still a notable contributor to the overall revenue. The steel can be sold as scrap metal for use in the steel industry, adding an additional income stream for plant operators. Factors Affecting Profitability While tire pyrolysis projects offer multiple revenue streams, their profitability is influenced by several critical factors that determine operational efficiency and cost-effectiveness. Capital and Operating Costs One of the main challenges in establishing a profitable continuous tyre pyrolysis plant is the high initial capital investment required. The cost of purchasing and installing a pyrolysis plant can be substantial, particularly when considering advanced technologies that ensure higher efficiency and better product yields. In addition to the initial investment, operating costs such as labor, maintenance, and energy consumption can add up quickly. The key to profitability lies in optimizing the operational costs while maximizing product yield and quality. Feedstock Availability and Cost The availability and cost of feedstock—waste tires—are crucial in determining the economic viability of a tire pyrolysis project. In many regions, waste tire disposal is a growing concern, making tire pyrolysis an attractive option for waste management. However, in areas with abundant and affordable tire waste, the cost of feedstock may be lower, which directly impacts profitability. In contrast, regions where tire waste is scarce or expensive can reduce the economic feasibility of such projects. Product Yield and Quality The efficiency of the pyrolysis process directly affects the quantity and quality of the products produced. The yield of fuel oil, carbon black, and steel wire can vary depending on the temperature, pressure, and other operating parameters within the pyrolysis plant. Optimizing these conditions is essential for maximizing output and reducing waste. In addition, the quality of carbon black and fuel oil plays a significant role in determining their market value. High-quality products are more likely to command a higher price, which enhances the profitability of the project. Regulatory and Environmental Compliance As with any industrial operation, tire pyrolysis plants must comply with local environmental regulations, including those governing emissions, waste management, and safety standards. Compliance with these regulations can require additional investment in emission control systems, waste handling, and air quality monitoring. While these regulatory requirements are essential for sustainable operation, they can also increase the overall costs of running a pyrolysis plant. Nonetheless, proper adherence to environmental standards is critical to the long-term success of any tire pyrolysis project. Market Demand and Economic Factors The market demand for the products derived from tire pyrolysis plays a significant role in determining profitability. Fluctuations in the prices of fuel oil, carbon black, and steel wire can directly affect revenue generation. Additionally, shifts in global economic conditions, such as changes in oil prices or the demand for carbon black in various industries, can impact the financial stability of a pyrolysis plant. To mitigate these risks, it is crucial to diversify markets for the by-products and build strong relationships with key customers.
The conversion of plastic waste into usable fuel is a thermochemical process that fundamentally alters polymeric structures. Unlike mechanical recycling, which reshapes plastic without changing its chemical composition, thermal degradation breaks down long-chain hydrocarbon molecules into smaller, energy-rich compounds. A pyrolysis plant serves as the reactor environment for this controlled molecular transformation, turning heterogeneous plastic inputs into valuable liquid and gaseous fuels through depolymerization, cracking, and condensation mechanisms. Depolymerization of Synthetic Polymers The primary chemical transformation begins with the depolymerization of plastics. Most plastic waste streams—polyethylene (PE), polypropylene (PP), and polystyrene (PS)—consist of long hydrocarbon chains formed through addition polymerization. Under elevated temperatures (typically 350°C–500°C) in an oxygen-deprived plastic pyrolysis reactor , the polymer chains absorb thermal energy and reach their activation energy threshold. As the temperature rises, covalent bonds between monomer units weaken and begin to break. This process, known as random scission, produces a complex mixture of radicals, oligomers, and low-molecular-weight hydrocarbons. The specific bond dissociation pathways are influenced by the polymer type and the residence time in the reactor. Thermal Cracking and Molecular Fragmentation Once the polymeric backbone is destabilized, thermal cracking intensifies the degradation process. Cracking reactions cleave C–C and C–H bonds, producing alkanes, alkenes, and aromatic compounds. These reactions are highly endothermic and can occur via free-radical mechanisms, especially in the absence of catalysts. In a plastic into fuel machine , the reactor design (e.g., rotary kiln, fluidized bed, or auger type) determines heat distribution and molecular residence time, directly impacting the product composition. Shorter residence times favor lighter hydrocarbons and gas formation, while longer durations can promote secondary cracking of intermediates into lower-boiling-range compounds. The gaseous phase contains hydrogen, methane, ethylene, and butane, while the condensable vapor stream yields pyrolysis oil—comprising paraffins, olefins, naphthenes, and aromatics in varying proportions. Condensation and Phase Separation As the vapor exits the high-temperature zone, it passes through a series of condensers in a controlled cooling process. This step selectively condenses heavier hydrocarbons into liquid fuel fractions while allowing non-condensable gases to be recovered for combustion or storage. The resulting pyrolysis oil exhibits a variable composition, typically containing C5–C20 hydrocarbons with heating values ranging from 38–42 MJ/kg. The oil may contain traces of oxygenates, sulfur compounds, and halogenated derivatives depending on the feedstock purity. Further refining may involve distillation, hydroprocessing, or catalytic upgrading to produce transportation-grade fuels. Non-condensable gases such as hydrogen, carbon monoxide, and light hydrocarbons are often recirculated into the pyrolysis plant to fuel the reactor, enhancing energy efficiency and lowering operational costs. Solid Residue and Char Formation In addition to fuel products, the process generates solid carbonaceous residue—commonly referred to as char. This by-product consists of unconverted carbon, inorganic fillers, and additives present in the original plastic. While its calorific value is lower than that of pyrolysis oil, char can be used in industrial heating or further processed into activated carbon, depending on composition. Certain reactor configurations may also be equipped with dechlorination or filtration systems to capture problematic elements like PVC-derived hydrogen chloride, thus protecting the integrity of downstream systems and meeting emission standards. Influence of Polymer Type on Conversion Outcomes The molecular transformation pathway varies by plastic type. Polyethylene and polypropylene yield high liquid fuel ratios due to their saturated hydrocarbon structure. Polystyrene predominantly forms aromatic hydrocarbons, particularly styrene monomer. Polyvinyl chloride (PVC) and polyethylene terephthalate (PET), if present, introduce complications such as corrosive by-products and require pretreatment or segregation to prevent process instability. Optimizing feedstock composition in the pyrolysis plant is essential for maximizing fuel yield and minimizing secondary contamination. Sorting technologies and chemical compatibility analysis play a critical role in ensuring product uniformity and economic viability. In thermochemical terms, the transformation from plastic to fuel is a decomposition–recombination sequence governed by temperature, pressure, and feedstock chemistry. The pyrolysis plant acts as the controlled environment in which synthetic polymers are dismantled at the molecular level and reassembled into usable energy carriers. Through precise process control, waste plastic becomes a source of liquid hydrocarbons, supporting both waste reduction and alternative fuel production in a carbon-constrained economy.
