On December 29th, 2025, Beston Group successfully launched a high-efficiency oil sludge treatment project in Africa. Utilizing advanced TDU pyrolysis technology, the project converts industrial hazardous waste into high-value resources, marking a significant step forward for the region in achieving a circular economy and meeting environmental regulatory standards. Below are the detailed insights into this project:

Issues Faced & Core Objectives
- Issues: A mid-sized solid waste management company in Africa had long struggled with massive accumulations of oil sludge. Their previous incineration methods caused severe smoke pollution and a harsh operating environment (high temperatures and odors), making it impossible to meet local environmental regulations.
- Objectives: To implement advanced pyrolysis equipment that is stable in operation, highly automated, and capable of resource recovery.

Solution & Action: BLJ-16 TDU System
After a thorough assessment of the client’s site conditions and processing requirements, Beston Group provided a high-performance BLJ-16 Thermal Desorption Unit (TDU) solution. Below are the key project specifications for your reference:
Model Configuration
- Model: BLJ-16 thermal desorption unit (standard configuration)
- Process capacity: 16-18t/batch
- Working method: Batch
- Feeding system: Integrated combination of screw feeding and belt conveying
Project Information
- Raw material: Oil-based drill cuttings (moisture & oil content: ~35%)
- Project start date: March 27, 2025
- Successful operation date: December 29, 2025
- Project duration: 277 Days

Delivery Journey: Field Challenges & Professional Response
From November 16 to December 29, 2025, Beston Group completed the on-site installation in just 44 days. By using their technical skills, they solved several site problems to ensure the machine operated on time:
Challenge 1
Power Shortages and Material Loss
- The issue: Frequent power failures at the site and some parts damaged during shipping threatened the schedule.
- The solution: The team worked on “no-power” tasks first (like manual marking and tightening bolts). We also helped the client find matching parts in the local market so work never stopped.
Challenge 2
Bad Weather Interference
- The issue: Heavy rain during the rainy season stopped outdoor welding and slowed down the work.
- The solution: Engineers set up temporary sheds and moved the work focus to indoor pipe welding. This kept the project moving despite the rain.
Challenge 3
Physical Damage to Core Components
- The issue: Improper unloading by onsite personnel caused physical deformation to the bottom of the oil gas condenser, which could cause leaks.
- The solution: The technical team fixed the bend on-site and reinforced the metal. After high-pressure tests, the machine was perfectly sealed and safe to use.

Project Value & Results
Following the successful 15-ton oil sludge commissioning run in late December 2025, the plant is now fully operational, delivering the following key values to the client:
- Environmental compliance: The closed-loop operation eliminated the smoke emissions associated with traditional incineration.
- Economic circularity: The produced pyrolysis oil not only fuels the equipment but the surplus also generates additional profit for the client.
- Brand elevation: The stable operation of this project has helped the client transform from a traditional “incineration station” into a benchmark enterprise for environmental treatment in the region.
