How HERING WORP® Is Redefining Waste Oil Recycling: Scientific Innovation Meets Commercial Impact

In an era where environmental sustainability is no longer optional but essential, waste oil poses a serious global challenge. Every year, millions of gallons of used lubricants from automobiles, manufacturing plants, and industrial equipment are either burned, dumped into landfills, or illegally discarded leading to disastrous consequences for soil, water, and ecosystems. According to environmental experts, just one gallon of used oil has the potential to contaminate up to a million gallons of fresh water. This stark reality highlights the urgent need for scalable and efficient recycling solutions that can turn hazardous waste into valuable resources.

Enter the HERING WORP® waste oil re-refining plant, an advanced system engineered by HERING VPT that is setting new benchmarks in oil recovery technology. Leveraging a combination of non-cracking vacuum distillation and RCPS (Reusable Clay Polishing System), the HERING WORP® system transforms used oils into high-quality Group I and Group II base oils. These base oils meet the same API and ASTM standards as those derived from crude, making them a viable substitute for virgin materials.

The global scale of the problem cannot be overstated. In the European Union alone, over three million tonnes of used oil are generated annually. Worldwide, a significant portion of used oil—estimated at over 30%—goes unaccounted for, often ending up in places it shouldn’t. Even when oil is collected, a substantial share is incinerated as a dirty fuel, contributing to air pollution and missing the opportunity for full re-refinement. These inefficient practices are both economically and environmentally costly.

Used oil re-refining differs fundamentally from simple recycling. It is a technologically advanced process that involves dehydration, vacuum distillation, and final-stage polishing to remove impurities, contaminants, and degraded additives. Unlike outdated acid-clay methods, HERING WORP® deploys a modern thin-film evaporation technique that prevents oil cracking, improves yield, and avoids the production of hazardous waste.

One of the standout features of the HERING WORP® plant is its modular, plug-and-play architecture. This makes the system suitable for businesses of all sizes—from small-scale recyclers to large industrial operations. With no need for acids or chemical additives, and no cracking involved, the plant achieves up to 80% base oil recovery. The integrated RCPS unit efficiently removes sulfur, odor, and color, delivering a clean output that consistently meets the performance expectations of Group II base oils.

A real-world example of HERING WORP® in action comes from the Middle East, where a 4,000-liter-per-hour unit was commissioned. The system achieved base oil yields of around 75%, complied with Group II sulfur specifications, and reused light fuel by-products to heat its own processes—resulting in a full return on investment in less than four years. Such installations illustrate the dual benefits of sustainability and profitability, making HERING WORP® an attractive option for industries looking to modernize their waste management practices.

Deploying a HERING VPT re-refining system reduces the demand for crude oil, lowers carbon emissions, and eliminates the environmental risks associated with improper oil disposal. Additionally, the process consumes only one-third of the energy required to produce base oils from virgin feedstock. In many cases, operators report a payback period of just two to five years, along with compliance benefits for ESG reporting and regulatory mandates.

A wide range of industries stand to benefit from this technology. These include automotive fleets, mining and construction firms, manufacturing plants, power generation companies, and waste oil collection businesses. For each of these sectors, HERING WORP® offers a practical and sustainable way to close the loop on lubricant usage while reducing operational costs and environmental footprint.

With more than a century of engineering excellence behind it, HERING VPT delivers fully integrated, turnkey systems that are globally supported and field-tested. The company’s commitment to innovation, safety, and customer success ensures that its clients receive not only cutting-edge technology but also reliable performance and peace of mind.

Waste oil is no longer a problem it’s an opportunity. By adopting HERING WORP®, businesses can transform environmental liability into long-term economic value.
