What Henan Doing Environmental Protection Technology Co.,Ltd does

Henan Doing Environmental Protection Technology Co., Ltd (operating as "DOING") is a Chinese manufacturer of pyrolysis and recycling equipment, established in 2015 as a subsidiary of DOING HOLDINGS and headquartered in Zhengzhou, Henan Province. The company designs and builds industrial-scale systems that convert waste streams — including end-of-life tires, mixed plastics, oil sludge, refinery residues, waste engine oil, biomass, printed circuit boards, lithium batteries, and solar photovoltaic panels — into fuel oil, carbon black, recovered metals, biochar, and combustible gas. Its technology stack is built around low-temperature thermal pyrolysis, catalyst-based distillation, electrostatic separation, physical multi-stage sorting, and continuous-feed carbonization, with two named in-house patents: a catalyst distillation system that converts waste oil into fuel oil and a decoking device that mitigates coking in coal tar and oil sludge processing.

The company generates revenue primarily through one-time equipment sales across a wide capacity range (100 kg/day portable units to 50 TPD fully continuous systems), bundled with installation, commissioning, operator training, and post-sale process optimization. Pricing is quote-based and capacity-driven rather than disclosed publicly. Distribution is direct-to-end-user via the company's website, email, phone, and WhatsApp/WeChat, supplemented by an overseas warehouse and branch operation in Nigeria that supports the African market. End customers are industrial buyers — waste recycling firms, oil and gas operators, e-waste processors, agricultural/biomass players, and investment vehicles — across more than 120 countries, with documented projects in Southeast Asia, South Asia, Central Asia, West and East Africa, Europe, the Baltics, Latin America, North America, and Oceania. Certification footprint includes CE and ISO marks as well as Chinese National High-Tech Enterprise designation.

Scale indicators7 records

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• Andritz: Andritz supplies large-scale industrial and environmental process equipment, including separation and recycling systems for waste streams. It overlaps with DOING on the industrial-equipment buyer but at a much higher scale and broader portfolio.
• Veolia: Global waste-management giant that operates recycling and resource-recovery plants that are potential DOING equipment customers and competitors at the integrated project level — Veolia brings bundling and service revenue DOING cannot match.
• Suez: Waste-recycling operator and equipment/integrator across tire, plastic, and hazardous-waste streams in Europe and emerging markets — comparable as a downstream customer or competitor for integrated waste-to-resource projects.

Direct peers

• Beston Group: Beston is the most direct competitor to DOING — a Chinese manufacturer of waste-tire, plastic, and oil-sludge pyrolysis plants sold globally, with overlapping batch and continuous equipment lines and the same African/Southeast Asian project customer base.
• Klean Industries: Klean designs and supplies tire and plastic pyrolysis plants globally with a comparable turnkey project model, positioned as a Western-headquartered alternative to DOING for large-scale pyrolysis deployments.
• Henan Niute Environmental Protection Technology: Henan-based pyrolysis equipment peer with overlapping batch and continuous waste-tire/plastic lines, exported to similar emerging-market buyers — closely comparable technology stack and GTM motion to DOING.

Emerging players

• Brightmark: Brightmark develops plastics-to-fuel pyrolysis projects in the US, overlapping on the plastic-pyrolysis use case. While project-developer rather than equipment maker, it competes to influence which equipment platforms the industry standardizes on.
• GreenMantra Technologies: Canadian plastics-pyrolysis company converting mixed polyolefins into specialty chemicals, overlapping with DOING's plastic-to-fuel platform on feedstock and end-market.
