Engineering cleaner air with a patented Nigerian invention
Benemes International is home to the Air Pollution Strainers (APS) a direct carbon capture technology registered and patented by the Federal Republic of Nigeria. From our base at the Technology Incubation Center in Port Harcourt, we design, build, and deploy engineering solutions that take carbon straight out of the air where it's produced.
Certificate of Registration of Patent
Patents and Designs Act; CAP 344, Laws of the Federation of Nigeria 1990
Direct carbon capture from the source of emissions storage and utilisation, engineered in Nigeria.
A Nigerian technology incubation company, built around one patented idea
Benemes International operates out of the Technology Incubation Center under the Nigeria Board for Technology Incubation in Port Harcourt, Rivers State. Our flagship invention, the Air Pollution Strainers (APS), is a split-unit direct carbon capture system: one unit installed right at the point of emission, and a processing unit positioned nearby for monitoring, evaluation, storage, and utilisation.
The system captures over 98% of emissions at the source before they reach the atmosphere, helping industries offset their carbon footprint while advancing UN Sustainable Development Goals 3, 9, and 13 good health, industry & infrastructure, and climate action.
From point of emission to clean, monitored air
APS is engineered as two connected units, so capture happens right where the emission is produced not downstream, after the damage is done.
Stage One
Capture at the source
The strainer unit is fitted directly at the emission point a factory exhaust, a generator outlet, or a vehicle tailpipe intercepting gases before they disperse.
Stage Two
Monitor & evaluate
A processing unit positioned nearby continuously evaluates what's been captured, so operators know exactly what's being removed from the air.
Stage Three
Store & utilise
Captured carbon is held for safe storage or routed for utilisation, closing the loop instead of letting it re-enter the atmosphere.
One capture technology, engineered for every source
Three purpose-built variants of the Air Pollution Strainers, each designed for a different emission source.
Factory Hazardous Gas Capture APS
Rotates as it captures dangerous gas emissions and particulates, maintaining a safe working environment on factory floors.
ViewAPS for Small Generators
Captures generator fumes and releases cleaner air, eliminating the risk of sudden death common to small-generator use at home.
ViewAPS for Vehicles
Installed on vehicles to reduce exhaust emissions down to a tolerable, safer level for cleaner city air.
ViewAligned with the UN Sustainable Development Goals
Capturing carbon at the source doesn't just clean the air, it advances goals that matter to industry, government, and public health.
Good Health & Well-being
Reducing generator and industrial fumes at the source lowers the everyday health risks that come with poor air quality in homes and workplaces.
Industry, Innovation & Infrastructure
A locally engineered, federally patented technology gives Nigerian industry a homegrown route to cleaner, more resilient infrastructure.
Climate Action
Direct source capture helps industries offset their carbon footprint, supporting national and corporate climate commitments.

Start a partnershipFrequently asked questions
A quick primer on what APS is and how it fits into a facility, home, or vehicle.
What exactly does an Air Pollution Strainer do?
It intercepts gas emissions and particulates right at the source a factory exhaust, generator outlet, or vehicle tailpipe before they disperse into the surrounding air, then routes what's captured to a processing unit for monitoring, storage, or utilisation.
Who is APS designed for?
Three variants cover industrial factory floors, residential and small-business generator setups, and vehicles anywhere combustion produces emissions that would otherwise reach the open air untreated.
Is the technology protected?
Yes. APS is registered and sealed under Nigeria's Patents and Designs Act, CAP 344 LFN 1990, with Patent No. RP: NG/PT/NC//2019/4013, patentee Benemes Nigeria Limited.
