Waste tires are built to resist heat, mechanical stress, and degradation — the properties that make them durable in service make them intractable as waste. They consume land, present a persistent fire risk, and do not break down.

Pyrolysis converts them into oil, carbon black, steel, and gas, but doing so continuously rather than in batches requires sealed feeding, pressure control under negative draft, and heat management that few systems sustain at industrial scale.

The harder problem sits downstream: pyrolysis carbon black as produced is low-grade and cannot be used widely in rubber, so the economics of a tire pyrolysis plant depend as much on upgrading the carbon black as on the reactor itself.

Qingdao Ecostar Resource Recycling Equipment Co., Ltd. (伊克斯达) develops and manufactures green tire pyrolysis and carbon black deep-processing technology and equipment. The company states it has resolved 17 key common technical problems in waste tire circular utilization and received a major special project from the Ministry of Science and Technology in this field.

Continuous pyrolysis

The intelligent continuous pyrolysis equipment is built on ten core technologies, including controlled continuous feed sealing, self-adjusting micro-negative-pressure control, and hot-air circulation reuse. Sealed continuous feeding is what allows the line to run without batch cycling; the negative-pressure control keeps gas from escaping at the seals; and hot-air circulation cuts the external energy the process requires.

Carbon black upgrading

The deep-processing equipment carries five core technologies — crushing and magnetic separation of pyrolysis carbon, high-efficiency jet milling and classification, and continuous stable granulation. This is the stage that determines whether the carbon black can leave the plant as a product: jet milling and classification bring particle size into specification, magnetic separation removes residual steel, and granulation makes the material easier to handle for compounding customers.

Ecostar reports resulting process advantages in efficiency, energy consumption, quality, and added value.

Yields

A waste tire processed through the line yields approximately 40% oil, 30% carbon black, 20% steel wire, and 10% combustible gas. The oil serves as refinery feedstock; the steel returns to smelting; the upgraded carbon black is applied in rubber, construction, and road building; and the gas is recovered to fuel both pyrolysis and carbon black processing.

The company describes the outcome as zero emission, zero residue, zero pollution, and full utilization. Citing China Association of Circular Economy data, it states each ton of waste tires handled reduces CO₂ by 1.1 tons.

Whole-plant delivery

Beyond equipment, Ecostar delivers complete intelligent factory build-and-operate packages — from tire intake through to finished product — with its own plants running continuously as validation of equipment reliability, so customers receive proven process and operating experience rather than a design. The company states it has supplied customers across more than 20 industries, including tire, plastics, building materials, rubber products, and petrochemicals.
