Harden's recycling solution integrates several advanced processing techniques that effectively convert discarded tires into Tire Derived Fuel (TDF). The system involves various stages, including coarse shredding, fine shredding, and screening, processing the waste tires into TDF alternative fuel sized at 50mm, with an output size compliance rate exceeding 99%. Through these advanced technologies, Harden optimizes the physical properties of the tires, efficiently extracting their inherent energy to produce a more stable alternative fuel for industrial kilns.

Compared to traditional fossil fuels, TDF's high calorific value makes it an ideal substitute for energy-intensive facilities such as cement kilns and pulp and paper production. Local South African environmental firms stated, “The TDF produced from waste tires will ultimately be applied in the industrial kilns of cement factories, achieving a calorific value of 7500 kcal, which is 20% higher than that of coal. The TDF from Harden's processing system is more uniform and refined, leading to more stable calorific fluctuations in practical applications within industrial kilns, perfectly meeting our requirements.”

Harden's TDF production system not only aims to enhance energy efficiency but also provides a solution to reduce dependence on fossil fuels. Currently, South Africa generates approximately 300,000 tons of waste tires annually, yet its recycling rate is below 20%. By promoting the use of TDF, Harden's project has the potential to decrease the demand for traditional fuels, alleviate landfill pressures, and facilitate the effective conversion of waste tires into renewable energy, making a positive contribution to environmental protection.

Additionally, the project addresses the environmental risks associated with the accumulation of waste tires. The buildup of waste tires can not only lead to fires but also provide breeding grounds for pests, such as mosquitoes and rodents, posing public health risks. The conversion to TDF will significantly mitigate these accumulation issues and fundamentally reduce environmental hazards.

Notably, Harden's solution adheres strictly to relevant environmental regulations. Environmental agencies in many countries have recommended the incorporation of TDF in cement kilns during coal combustion to reduce emissions of nitrogen oxides (NOx) and sulfur oxides (SOx). This practice not only enhances combustion efficiency but also allows the ash produced from TDF burning to be treated as a resource, effectively decreasing landfill demand and increasing resource reuse.

In conclusion, the project undertaken by Harden Machinery Ltd. in South Africa has not only improved energy efficiency but also laid a sustainable foundation for waste management. Through this innovative solution, Harden fosters a balanced coexistence between environmental protection and economic growth. Looking to the future, Harden aims to extend the reach of this technology to more regions, further bolstering environmental initiatives and making a positive contribution to global sustainable development.
