1. Industry Background & Challenges
A medium‑sized heavy machinery manufacturing enterprise in Australia has long been troubled by waste oil management issues. The enterprise is mainly engaged in the production of parts for mining equipment. In daily operation, its hydraulic systems, engine units and other equipment continuously generate a large volume of waste engine oil and waste hydraulic oil, with a considerable annual output.
Local environmental regulations impose very strict requirements on hazardous waste disposal. Entrusting third‑party professional institutions for treatment not only incurs high transportation costs, but also often requires scheduling several months in advance due to limited local hazardous waste treatment capacity in Australia, frequently leading to waste oil backlog. Meanwhile, traditional disposal methods such as open‑air storage or simple landfilling not only violate local environmental regulations, but also bring legal risks of soil and groundwater pollution. The enterprise once received rectification notices from regulatory authorities due to non‑standard disposal.
In addition, the enterprise’s production and backup power generation systems are highly dependent on purchased diesel. Affected by fluctuations in international oil prices, procurement costs have continued to rise. Meanwhile, a large amount of waste oil is only treated as waste without being recycled. Dual pressures of environmental compliance risks and economic costs have seriously restricted the enterprise’s production expansion plans.
2. Solution
After an in‑depth investigation of local environmental standards in Australia, the characteristics of the enterprise’s waste oil, and its actual energy demand, the enterprise established in‑depth cooperation with our company.
In response to Australia’s dry climate, complex working conditions and high requirements for automation, we customized a complete waste oil regeneration diesel system suitable for high‑temperature and dry environments. The solution adopts mature technologies including high‑efficiency catalytic cracking and precision rectification, equipped with an intelligent control system compatible with Australian electrical standards, which can accurately adapt to the regeneration of different types of waste oil and ensure that the produced diesel meets local industrial energy standards.
We provided full‑process one‑stop service, covering on‑site survey, process optimization and design in the early stage, modular manufacturing and full‑condition testing of equipment, cross‑border sea freight logistics planning, as well as on‑site installation, commissioning and operator training abroad. Our professional technical team provided full guidance, helping the client complete site planning, pipeline connection and safety system construction, and carried out targeted training in line with local operation specifications, enabling the operation and maintenance team to quickly master equipment operation, routine maintenance and emergency handling skills, ensuring efficient implementation from design to commissioning.
3. Project Outcomes
After the project was put into operation, the enterprise achieved harmless and resourceful closed‑loop treatment of waste oil, completely solving environmental compliance problems, eliminating annual waste oil backlog, and no longer bearing high costs of third‑party hazardous waste treatment and transportation.
The regenerated diesel features stable quality and can be directly used in the enterprise’s generator sets and partial production equipment, fully replacing purchased diesel. It is estimated that, including savings in diesel procurement, waste oil disposal and potential environmental rectification costs, the enterprise reduces annual costs by millions of US dollars. Meanwhile, the high degree of automation of the equipment greatly reduces manual maintenance input and significantly improves the self‑sufficiency rate of production energy.
This project has become a benchmark for industrial waste oil recycling in the Australian region. The client highly recognizes the stability of the equipment, process adaptability and full‑process services, and plans to promote the solution to other overseas factories under the group.
