Harden Machinery Ltd. Pioneers Eco-Friendly Waste Tire Solutions in South Africa
As a renowned manufacturer in the global waste management equipment industry, Harden Machinery Ltd. has recently collaborated with local environmental enterprises in South Africa to successfully launch an innovative waste tire resource recovery project, providing a practical new solution for waste management in the country.
Harden's resource recovery solution integrates multiple advanced processing technologies that effectively convert discarded tires into Tire Derived Fuel (TDF). This system includes several stages such as coarse shredding, fine shredding, and screening, processing waste tires into TDF substitute fuel sized to 50mm, with a compliance rate of over 99% for output size.
Through these advanced technologies, Harden maximizes the optimization of the physical properties of the tires, fully extracting their inherent energy, thereby producing an industrial kiln substitute fuel with a more stable combustion heat value fluctuation.
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.
Furthermore, this project addresses the environmental hazards that may arise from the accumulation of waste tires. The accumulation of waste tires not only poses a fire risk but also provides breeding grounds for disease vectors such as mosquitoes and rodents, leading to public health risks. The conversion of these tires into TDF will significantly alleviate the accumulation problem, fundamentally reducing environmental risks.
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 summary, the project implemented by Harden Machinery Ltd. in South Africa not only enhances energy utilization efficiency but also paves the way for sustainable waste management. Through this innovative solution, Harden promotes a harmonious coexistence of environmental protection and economic development. Looking ahead, Harden hopes to promote this technology in more regions, further supporting environmental protection practices and contributing positively to global sustainable development.
