Reference project
Eliminating VOCs at Hazardous Waste Management Facility
Introduction.
Mellifiq’s three-stage treatment solution eliminates VOC emissions and complies with strict environmental standards
In this project, we are partnering with a leading waste management company in Skåne to implement an Advanced Oxidation Process (AOP) solution, along with additional polishing steps, to address VOC (Volatile Organic Compounds) emissions. Headquartered in Malmö, the company specializes in treating hazardous waste, including liquid waste, sludge, and similar substances.
The problem.
To comply with the strict VOC (Volatile Organic Compounds) limits set by the European Commission under the Industrial Emissions Directive (IED) 2010/75/-EU, our partner needed to effectively manage and treat emissions from hazardous liquid waste arriving by tankers. During the unloading process, the waste is discharged in to a designated area, releasing a significant amount of VOCs that require effective treatment.
These compounds at waste management facilities pose several environmental and health-related challenges, including air pollution, regulatory compliance, and worker exposure risks. The composition of VOCs is unknown, but the primary sourceis oil. A total of 2,200 kg/year of VOCs is currently being emitted at the facility, while upcoming regulations require emissions to be reduced to 1,500 kg/year. Additionally, VOC concentrations must not exceed 40 mg/m³ at any measurement point.
The solution.
With a strong focus on environmental responsibility, the company turned to Mellifiq for assistance in achieving its emissions reduction goals. Mellifiq provided an Advanced Oxidation Process (AOP) solution, which includes a turnkey ozone system and a high-capacity UV system that treats up to 90% of the VOCs, followed by a final polishing step that ensures VOC reduction even with variable pollution loads. All liquid waste treatment processes, including sedimentation tanks, filter systems, and buffer tanks, are connected to air ducts that merge into a single exhaust stream. The collected exhaust gas is treated with ozone generated by an Ozonetech Rena Pro at two injection points.
The first injection occurs early in the process, allowing the ozone to react with the VOCs. The second injection takes place just before the Saniray UV filter, where ozone-VOC reactions are enhanced by the low-pressure UV-C in the Saniray Aurora system, forming the AOP necessary to break down challenging VOC compounds. Finally, the gas passes through a Nodora X system, which removes any remaining traces of VOC emissions.

Evaluation.
Despite initially high VOC levels, Mellifiq’s comprehensive three-stage treatment solution ensures that final emissions consistently remain well below the regulatory threshold of 40 mg/m³. With a treatment capacity of2,000 m³/h, the solution offers an efficient, scalable,and reliable method for meeting strict environmental standards.
Mellifiq significantly reduces the environmental footprint of waste management operations through close collaboration with the client, providing a tailored approach to address both current and future emission reduction goals.
