Innopack Systems and Pure Infinity have been working together for 10 years. In the flexographic market, Pure Infinity provides Innopack’s customers with the most competitive VOC treatment systems available: the VOCUS and -since 2019- also the new BONCUS system.
Both systems provide solvent emissions treatment technologies based on biology, which will have a much lower maintenance cost than traditional RTO’s or Incinerators. The elegant and modern systems of Pure Infinity are very easy to operate and are already successfully running at over 10 customers in Spain and Portugal.
VOCUS was specifically designed for flexo companies with one printer or with low ink coverage jobs. The VOCUS will easily remove the solvents from the air emissions at a very low cost, as the biology will eat the solvents nearly for free. Additionally, with the new BONCUS, the solvents are converted to gas that can then be utilised to heat the drying air during the flexo printing process or other processes that require heat. In some cases, the gas can even be used to produce electricity in combination with heat, increasing the value of the energy released. The energy that it produces is considered green energy, so the carbon footprint will be reduced significantly. Therefore, the BONCUS will not only save CO2, but it will also give a return on investment whilst still removing the solvents from the air.

BONCUS treating solvent air emission from flexographic industy
The first BONCUS system – a solvent air emission treatment system that converts the air emissions from a flexographic printing company into energy- is ready for commissioning. There is finally a payback model for the waste solvents in the flexographic industry. Pure Infinity has developed this technology for air treatment together with the University of Valencia and is thrilled with the finalization of this project. This project proofs the fit for the BONCUS in the industry. This project consist of a hybrid system with a VOCUS and BONCUS combination.
Solvent air emissions in the flexographic industry are to be treated according EU legislation’s to prevent photo-chemical SMOG in the atmosphere. See also here for more information.
The solvents in the air emissions are removed from the air and subsequently biologically converted into bio-methane. First the air is treated in a scrubber with water to clean the air. The air is than clean enough to emit to the atmosphere. As a second step the water is fed into a biological reactor where bacteria are converting the solvents into methane: green gas. This green gas can be used without further treatment to heat a thermal oil burner or to produce electricity in a CHP (combined heat and power unit). In every location the options should be looked at in detail to maximize the financial business case. Read more on the BONCUS over here.
Bio-methane is also called green-gas referring to what it is: renewable energy. Turning the waste solvent emission into energy and at the same time contributing to the energy transition.

Finland-based Exel Composites has completed a four-year project called Next Air Biotreat that explored biotrickling filtration as a way to limit styrene emissions. One of the most widely-discussed concerns among the composites industry is how to control styrene – a volatile component of polyester resin. In the past, researchers have tried to clean the styrene-contaminated air inside and outside production facilities, but those methods have often been very energy-intensive. To combat this problem, Exel Composites collaborated with the University of Valencia in Spain and Pure Air Solutions from the Netherlands to explore biotrickling filtration.“Biotrickling filtration is a combination of a biofilter and a bioscrubber. It is a biological system that uses clean and natural processes to remove VOCs [volatile organic compounds],” says Eric Moussiaux, General Manager of Exel Composites’ Belgium unit. “The styrene fumes are absorbed in water and decomposed by bacteria. The pilot unit erected at [our Oudenaarde, Belgium] factory proved to be very efficient. We will certainly do the necessary investments to take this process into use,” he added.
Professor Carmen Gabaldón from the Chemical Engineering Department of the University of Valencia, who led the project, believes the project was a success.
“We are extremely pleased with the results of the project,” Gabaldón said. “In comparison with conventional technologies, biological VOC treatment is economically beneficial, it contributes to a lower ecological footprint and implies a reduction of CO2”, Prof. Gabaldón continues.
The issue has become a particular hot topic in the United States as well, with the California EPA recently adding styrene to its list of substances “known to the state to cause cancer” under its Proposition 65 regulation. While there has not been a significant foray into biofiltration in the United States, the American Composites Manufacturers Association has released guidelines and tools to help manufacturers determine if their products are below Calfornia’s proposed “No Significant Risk Level” of 27 micrograms per day average life time.

The Biotrickilng Filter performance is based on the natural process of biological oxidation (aerobic degradation) of organic compounds (COVs) that yields ultimately inert products such as carbon dioxide (CO2) and water. In a Biotrickling filter reactor, the polluted air to be treated is passed through a bed on which it has developed a film of microorganisms (biofilm) which are the responsible for degrading organic contaminants to carbon dioxide and water. In turn, an aqueous phase is circulated continuously through the bed allowing adequate biofilm irrigation. In the figure it can be seen the functioning of this system. This cleaning technology is especially attractive for treating large volumes of polluted air with low concentrations of (VOCs)
because of simplicity, low operational cost and minimal environmental impact since it does not generate toxic or hazardous waste products.
VOC removal from air emissions in industry is mainly based on the European Directives. These are in place to protect the environment from these VOC’s or also referred to as solvents. VOC’s generally create photochemical SMOG. SMOG is causing increasingly health problems in densed populated area’s in Europe.
Volatile organic compounds (VOCs) are carbon-based chemicals that easily evaporate into gaseous forms at room temperature. Commonly referred to as solvents, the human health risks associated with exposure to VOCs vary from mild to severe and are dependent upon several factors including length of time and level of exposure. Treatment of these various vapor sources to reduce the VOC emissions is often required to comply with regulations.
While some VOCs cause no known health effects, others are known to be highly toxic. Their effects vary and are dependent upon several factors including, most notably, length of time and level of exposure. Common symptoms associated with exposure to VOCs include eye, nose, and throat irration, nausea/vomiting, allergic skin irritation, dizziness, and visual disorders. Extended exposure in the long-term can result in more serious conditions such as cancer, damage to the liver, kidney, and central nervous system, and loss of coordination. More infomation on VOC’s can be found for example on wikipedia
VOC removal techniques
Numerous technologies exist to perform VOC reduction in vapor streams; The most environmental friendly and lowest cost solution, is to use biological techniques. Pure Infinity has a long experience in the biological treatment of solvent emissions from industry with our VOCUS biotrickling technology.
Other techniques all require additional chemicals, energy or adsorbtion material like activated carbon while in biological solutions it is the biology that works. Based on our experience, Pure Infinity promisses working solutions that have the lowest costs.
