Harden Machinery Ltd., a globally recognized leader in waste management equipment, has recently partnered with local environmental companies in South Africa to introduce an innovative waste tire recycling initiative. This project offers a practical and sustainable solution for the country's waste management challenges. Harden's approach combines several advanced technologies to efficiently convert waste tires into Tire Derived Fuel (TDF). The process involves multiple stages, including coarse and fine shredding, followed by screening, which produces TDF fuel sized to 50mm, achieving a compliance rate of over 99% for output size.
By leveraging these cutting-edge technologies, Harden optimizes the physical properties of the tires, effectively extracting their latent energy and converting it into a more stable industrial kiln fuel with consistent combustion heat values.
Compared to traditional fossil fuels, the high calorific value characteristic of TDF makes it an ideal alternative fuel for energy-intensive facilities such as cement kilns and pulp and paper production. A South African environmental enterprise stated: “The TDF substitute fuel derived from waste tires will ultimately be used in industrial kilns at cement plants, with a heat value of 7500 kcal, which is 20% higher than that of coal. The TDF obtained through Harden’s processing system is more uniform and finer, resulting in a more stable combustion heat value fluctuation in actual applications within industrial kilns, perfectly meeting our requirements.”
Harden's TDF production system not only aims to enhance energy efficiency but also provides solutions for reducing dependence on fossil fuels. Currently, South Africa generates approximately 300,000 tons of waste tires annually, yet its recycling rate is less than 20%. By promoting the application of TDF, Harden's project is expected to reduce the demand for traditional fuels, alleviate pressure on landfills, and facilitate the effective conversion of waste tires into renewable energy, making a positive contribution to environmental protection.
It is worth noting that Harden's solution strictly complies with relevant environmental regulations. Environmental agencies in many countries have recommended that cement kilns incorporate TDF when burning coal to reduce emissions of nitrogen oxides (NOx) and sulfur oxides (SOx). This practice not only enhances combustion efficiency but also allows the ashes produced from TDF combustion to be utilized as a resource, effectively decreasing landfill needs and improving resource recovery rates.
In conclusion, the project launched by Harden Machinery Ltd. in South Africa not only improves energy efficiency but also sets a benchmark for sustainable waste management. This innovative solution demonstrates Harden's commitment to balancing environmental protection with economic growth. Moving forward, Harden aims to expand the reach of this technology to additional regions, further advancing environmental sustainability and making a positive contribution to global development.
