Pyrolysis has long held immense promise for the resource utilization of organic solid waste. However, the industry has historically been bottlenecked by several critical hurdles: equipment coking, the difficulty of maintaining dynamic seals during continuous feeding and discharging, and the tendency of pyrolysis products to polymerize.

Consequently, most equipment has been limited to intermittent batch operations, making large-scale, long-term stable industrial operations elusive and leaving many projects stranded at the laboratory or pilot stage.

For a long time, foreign enterprises held a first-mover advantage in the high-end continuous pyrolysis equipment sector, posing high barriers to entry for many Chinese domestic projects.

This challenge highlights Niutech Environment Technology Corporation’s competitive advantage: entirely independent and controllable industrial continuous pyrolysis technology.

Unlike the widespread batch equipment in the industry, the company’s systems enable continuous feeding and discharging under oxygen-free or oxygen-deficient conditions. Operating within a securely sealed environment, the system drastically mitigates secondary pollution risks while advancing solid waste disposal toward harmless treatment, reduction, and high-value resource recycling. This approach finally unlocks the true potential of turning waste streams into valuable new resources.

The Breakthrough: Pyrolysis as Continuous Capability

The reason pyrolysis has long been viewed with optimism is precisely because it offers a viable path to reintroducing difficult-to-treat organic solid waste back into the resource cycle. Conversely, the reason it has struggled to scale globally is that achieving true "continuous operation" is an immense engineering hurdle.

The true significance of Niutech’s technology lies in its ability to overcome the industry's critical pain points—such as coking, dynamic sealing, and product polymerization—to chart a proven path toward industrial continuous operations.

For the industry, the value of this capability is transformative: it elevates pyrolysis from a process that is merely "feasible" to one that is "stable, continuous, and scalable", establishing a genuine industrial foundation for turning waste streams into valuable new resources.

Implementation: The Power of Turning Waste into Treasure

Niutech has successfully transformed laboratory breakthroughs into tangible, real-world recycling success stories.

1.Karamay, Xinjiang

Oilfield extraction leaves behind vast amounts of oily sludge, which not only occupies valuable land but also poses significant environmental risks. Niutech implemented a globally leading-scale single-facility industrial continuous pyrolysis project here, with an annual processing capacity exceeding one million tons. The system efficiently recovers crude oil from the oily sludge while ensuring the remaining residues meet strict environmental disposal standards.

This project reduces carbon emissions by 336,000 tons annually and was awarded the First Prize of the Xinjiang Science and Technology Progress Award, successfully achieving the localized, high-value disposal of hazardous oilfield waste.

2.Zouping, Shandong

Serving as a national-level demonstration project for the comprehensive utilization of waste tires, Niutech’s waste tire pyrolysis project has established a stable and reliable resource recovery pathway. Through the company’s advanced pyrolysis equipment, discarded old tires are converted into recycled oil, pyrolysis carbon black, steel wire, and combustible gas, achieving complete resource utilization.

The "black pollution" that once caused severe industrial headaches is now being successfully transformed into valuable raw materials for industrial production.

What is even more remarkable is that this technology is not limited to waste tires and waste plastics; it also covers over thirty distinct scenarios involving organic solid waste and hazardous waste, including oily sludge, coal tar residue, paint sludge, and medical waste. It even extends into application areas such as metallic ore reduction, continuously expanding the boundaries of the circular economy.

Transitioning from pure equipment manufacturing to a model of "equipment sales + project operations", Niutech provides complete, customized pyrolysis solutions tailored to different regions and diverse operating conditions.

Going Global: From Chinese Solutions to Worldwide Applications

This Chinese technology is continuously expanding its footprint, moving far beyond the domestic market to make a global impact.

1.Denmark Waste Plastics Disposal Project

The waste plastics disposal project in Denmark has gained recognition from BASF, with the pyrolysis products being reused to manufacture new plastics, successfully achieving a chemical loop from waste plastics back to new plastics.

Meanwhile, an EU-funded project in Hungary has obtained official testing and certification from an EU-authorized agency; a project in Germany has been successfully deployed; and a UK client signed a contract worth approximately RMB 198 million for a waste plastics pyrolysis production line. Chinese environmental protection equipment is continuously proving its worth and gaining validation across overseas markets.

While many environmental protection companies on the market focus solely on manufacturing single pieces of equipment, Niutech Environment Technology stands out as a full-chain service provider that integrates technology R&D, standard setting, high-end intelligent equipment manufacturing, and project construction and operation.

Niutech is simultaneously a participant and a driving force in shaping industry standards. The company served as the primary drafter for Chinese National Standards and has participated in the compilation of numerous other national, industrial, and group standards.

Recognized as a national-level "Little Giant" enterprise specializing in niche and innovative markets, its technologies and equipment have obtained certifications such as the European Union's CE mark. These systems continue to be deployed in overseas projects across Germany, the UK, Denmark, and Hungary, driving Chinese recycling solutions further into the international market.

While many industry peers focus solely on "disposing of waste", Niutech pursues high-value regeneration. This is demonstrated by

the chemical recycling pathway in the Denmark project, where waste plastic pyrolysis products are reused to manufacture new plastics;
the recovery of valuable oil resources from oily sludge;
and the extraction of valuable components through low-temperature reduction in specific mining scenarios.

It is not merely about destroying garbage, but about actively unlocking the hidden resource value within waste streams. This approach puts the circular concept of "urban mining" into practice and aligns perfectly with carbon neutrality goals and zero-waste city initiatives.

From laboratory research to domestic project implementation, and finally to winning overseas client recognition, the story of Niutech proves that the circular economy is far more than a political slogan. Driven by core, hardcore technology, it successfully transforms complex environmental headaches into sustainable industrial opportunities.
