Harden International Limited

What Harden International Limited does

Harden International Limited (operating as Harden Machinery Ltd.) is a privately-held Chinese industrial equipment manufacturer founded in 2010 and headquartered in the Torch Development Zone of Zhongshan City, Guangdong Province. The company designs, engineers, and manufactures industrial shredders (single-shaft, two-shaft, four-shaft, primary, and one-step models), screening and separation equipment (disc screens, triangle disc screens, combined vibrating screens, flip-flow screens, and single- and double-drum wind shifters), and integrates these into modular turnkey RDF/SRF alternative fuel preparation systems branded as DWS. Its patented close-packed crushing cutter shaft increases cutting efficiency by 50% and underpins the SG-series single-shaft shredders.

The company sells primarily through direct enterprise field sales, with quote-based pricing (no public list prices) to cement producers, coal-fired power plants, paper mills, and municipal or environmental-services waste operators. Revenue derives from three streams: (1) standalone hardware sales of shredders and separators, (2) turnkey DWS alternative fuel preparation systems delivered as customized projects, and (3) managed services where Harden operates Alternative Fuel Preparation Centres for clients, exemplified by a 200 tons/day facility for Huaxin Cement's Chongqing Diwei subsidiary. Demand generation is heavily event-driven, with booth presence at international trade fairs including RESIDUES EXPO (Mexico), Waste-to-Energy Asia Summit (Vietnam), and ISRI (Las Vegas), supported by LinkedIn, Instagram, Facebook, YouTube, and a content-marketing blog.

Harden has delivered more than 200 DWS projects across cement, power generation, paper manufacturing, and solid waste management, with named installations or partnerships in China (Huaxin Cement, a Hubei paper mill, a Shanxi power plant, an Anhui environmental firm), South Africa (waste-tire-to-TDF), Southeast Asia (50 t/h MSW-to-SRF), and service specialists covering the USA, Germany, Vietnam, South Korea, and Mexico. Documented technical outcomes include fuel substitution rates exceeding 60% (Huaxin Cement), more than 40,000 tonnes of coal saved annually per project, over 95% impurity removal in the DWS system, and over 99% output size compliance on the South African TDF line.

Revenue model

1. Industrial Equipment Manufacturing and Sales: Harden designs, engineers, and manufactures industrial shredders, sorting machines, and processing lines, selling this equipment directly to cement producers, power plants, paper mills, and municipal waste management operators. Equipment includes single-shaft shredders (SL Series, SG Series), two-shaft shredders (TS Series, TD Series, TDH Series), four-shaft shredders, primary shredders, disc screens, triangle disc screens, wind shifters, and combined vibrating screens. Pricing is quote-based for large industrial equipment.
2. RDF/SRF Alternative Fuel Preparation Systems (Turnkey Projects): Harden provides complete alternative fuel preparation system solutions including equipment integration, installation, and commissioning. Systems are designed for specific waste types (municipal solid waste, industrial waste, waste tires, biomass, paper mill waste, construction and demolition waste) and are sold as customized turnkey projects to industrial clients, enabling them to produce RDF/SRF for cement kiln and power plant combustion.
3. Alternative Fuel (RDF/SRF) Production as a Service: Harden has established Alternative Fuel Preparation Centres for clients, converting solid waste into RDF/SRF on a production basis. For example, Harden established a centre for Huaxin Diwei Cement with a daily capacity of 200 tons, processing nine categories of solid waste into alternative fuel.

Partnerships

Three partnerships are on record, tiered flagship and major.

• Chongqing Huaxin Diwei Cement Co., Ltd. (subsidiary of Huaxin Cement Co., Ltd.)flagshipStrategic or Co-development Partner · 1 November 2024Harden Machinery successfully partnered with Chongqing Huaxin Diwei Cement Co., Ltd., a wholly-owned subsidiary of Huaxin Cement Co., Ltd. (established 1907, the cradle of China's cement industry), to implement an alternative fuel benchmarking project. Harden established an Alternative Fuel Preparation Centre, employing a modular combination of two-stage fine crushing, screening, and dust removal equipment. The system achieves a daily capacity of 200 tons, converting nine categories of solid waste into RDF/SRF with contamination rate under 10%, and delivering a fuel substitution rate exceeding 60%. The project saves over 40,000 tonnes of coal annually, demonstrating Harden's ability to achieve measurable carbon reduction outcomes for global cement leaders.
• Local Environmental Companies in South AfricamajorStrategic or Co-development PartnerHarden Machinery collaborated with local environmental companies in South Africa to launch an innovative waste tire recycling project, providing a solution to convert discarded tires into Tire Derived Fuel (TDF). The system processes waste tires through coarse shredding, fine shredding, and screening to produce TDF at 50mm output size with a compliance rate exceeding 99%. South Africa generates approximately 300,000 tons of waste tires annually with a recycling rate below 20%, making this partnership strategically significant for environmental protection in the region.
• Local Stakeholders in Southeast AsiamajorStrategic or Co-development PartnerHarden Machinery partnered with local stakeholders in Southeast Asia to establish a new international project focused on sustainable waste management, converting municipal solid waste into high calorific value SRF/RDF. This project addresses urban household waste challenges using Harden's specialized RDF/SRF single-shaft shredder and advanced sorting technologies, achieving a design capacity of 50 tons per hour. The project represents Harden's expansion into new international markets.
