Emission limits, permits & BAT/BREF
EMISSION LIMITS: Requirements for Industrial Emissions
Permit, limit values or state of the art: see how the requirements fit together and what they mean technically.
Emission limits, permits and BAT/BREF
Industrial processes generate emission-relevant exhaust air. Legal and technical requirements vary depending on the process, pollutants, volume flow rate, location, type of system, and permit situation.
The legal framework differs from country to country. It usually covers emission limit values, permit requirements and the state of the art.
For operators, the question is no longer whether exhaust air treatment is necessary. The decisive question is how to treat it in a technically sensible way. Understanding this leads to better decisions for both plant and operation.
Briefly Explained
✓ The permit comes first. It decides whether your plant needs approval and which duties you have as operator.
✓ Limit values follow. Your permit sets emission limits and rules for measurement and monitoring.
✓ BAT/BREF defines the state of the art in the EU. KMA designs its systems to this strict standard.
Approval to operate your plant
Emission limits and monitoring
Best Available Techniques (BAT) under EU law.
Set by the local authority

Your site sets the requirements
Which limit values apply depends on your country and your site. In most cases they follow from your permit and your emission measurements.
What is in your exhaust air comes from your process and your measurements. This data shows which exhaust air treatment makes sense.
Our engineers use it to develop the concept that fits your site.
BAT, BREF, and BVT: Understanding the State of the Art
BAT stands for Best Available Techniques. The EU describes them industry by industry in so-called BREF documents: which techniques prevent or reduce the environmental impact of an industry sector most effectively? The key results are recorded in the BAT conclusions. In the EU, these are the binding reference for permit conditions and emission limit values.
No single process is prescribed. What matters is the technical level considered the state of the art for an industry as a whole. As techniques and industries evolve, the documents are regularly revised – new conclusions can directly change existing permit requirements.
The interplay: the BAT conclusions set the industry-wide technical level. Authorities translate this framework into concrete limit values and monitoring duties for your plant.
For exhaust air filtration, this means: It is not just the emission reduction that is evaluated, but also the energy used, the auxiliary materials required, and the waste generated. State of the art refers to the entire system – from capture at the source through suitable filter stages to energy efficiency, operational reliability, and heat recovery. The decisive question is not which filter is used, but whether the entire exhaust air concept fits the process, the load, and the operating mode.
KMA systems are designed for the strictest European requirements. They can also meet other national requirements. We develop the concept from the requirements that apply at your site.
FAQ
What is the TA Luft?
The TA Luft is the “Technical Instructions on Air Quality Control”. It is an important administrative regulation in German immission control law and specifies requirements that can play a role in industrial and commercial systems. For operators, it is particularly relevant when production processes can cause air pollution. This includes, for example, dust, smoke, aerosols, organic substances, odours, or gaseous components. The specific assessment always depends on the individual case.
Which companies is the TA Luft relevant for?
The TA Luft can be relevant for companies whose systems generate emission-relevant exhaust air. This includes, for example, businesses in metalworking, foundry, die casting, plastics processing, rubber and elastomer processing, the food industry, or industrial manufacturing. Decisive factors include the industry, system, substances, volume flow rate, location, and permit situation. It is important for operators to technically understand their own process exhaust air. From this, it can be derived which exhaust air filtration, filter technology, or heat recovery may be technically sensible.
What does the TA Luft have to do with industrial exhaust air filtration?
The TA Luft describes requirements for air pollution control and emission limitation that can play a role in certain industrial systems. Industrial exhaust air filtration can be a technical building block to reduce emissions from production processes. Whether an electrostatic precipitator, activated carbon filter, UV module, wet scrubber, heat exchanger, or combined filter system is suitable depends on the specific exhaust air load. KMA therefore considers the process, substances, temperatures, volume flow rates, and operating mode together. The goal is a technically appropriate solution.
What does the BImSchG regulate?
The Federal Immission Control Act forms a central basis of German immission control law. It deals with protection against harmful environmental impacts, for example from air pollution, noise, or similar effects. For manufacturing companies, the BImSchG is particularly relevant when systems can cause emissions. In everyday technical practice, it often concerns questions of emission reduction, exhaust air capture, filter technology, and system design. KMA supports operators in planning and implementing suitable technical exhaust air filtration systems but does not replace legal or permit advice.
What is the difference between BImSchG and TA Luft?
The BImSchG is the overarching German law for immission control, system operation, and operator obligations, while the TA Luft, as an administrative regulation to the BImSchG, specifies the requirements for air emissions, measurement, and monitoring within this framework.
When does a system require a permit according to BImSchG?
Whether a system requires a permit according to BImSchG depends, among other things, on the type of system, size, capacity, operating mode, and the specifications of the 4th BImSchV. This lists the types of systems for which an immission control permit may be required.
What does BAT or BREF mean?
BAT stands for “Best Available Techniques”. The EU describes them for each industry in BREF documents. The BAT conclusions in these documents are the reference for permit conditions and emission limits in the EU.
BREF documents are related to the Industrial Emissions Directive and the state of the art. For operators, BAT and BREF can provide important guidance when it comes to modern, efficient, and low-emission system concepts. In exhaust air filtration, filter technology, heat recovery, automatic cleaning, and energy-efficient system design can be technically relevant.
What are BAT reference documents?
BREF documents are the EU reference documents for each industry. They describe which techniques are the best available and which emission levels can be reached with them. They also frequently contain information on emission-related ranges. For operators of industrial systems, BAT reference documents can help to better classify technical requirements. However, the specific relevance depends on the respective process. KMA can support the technical assessment of which exhaust air filtration solution fits the process, exhaust air load, and operating mode.
Can modern filter systems help to reduce emissions?
Yes, modern filter systems can be an important building block for reducing industrial emissions. Depending on the process, particles, smoke, oil mist, aerosols, odours, VOCs, or other exhaust air components can be technically treated. Which technology is suitable depends on the substances, concentrations, temperatures, humidity, volume flow rate, and operating mode. In many applications, the connection with heat recovery is also interesting because exhaust air filtration and energy efficiency can be considered together. KMA supports the appropriate technical design for the respective location.
