Advancing VOC Emission Control in Flexible Packaging industries
Best Practices and Environmental Considerations
Flexible Packaging is a type of packaging that is characterized by its ability to conform and adapt to the shape of the product being packaged: it is widely used in various industries, including food and beverages, pharmaceuticals, personal care products, and more. Flexible packaging offers advantages such as lightweight construction, excellent barrier properties, extended shelf life, and convenience for consumers. Rotogravure, flexo, lamination, coating, and lacquering are different processes commonly employed in the production of flexible packaging.
Pioneering Sustainable VOC Emission Control in Printing and Packaging
In an era of increasing environmental awareness and stringent regulations,flexible packaging industries worldwide are facing immense pressure to reduce their ecological footprint. Nowhere is this more evident than in the printing, painting, and coating industry, where Volatile Organic Compounds (VOCs) pose significant challenges. DEC has emerged as a global leader, providing cutting-edge and sustainable solutions for VOC emission treatment and abatement, particularly for flexible packaging converting and diverse printing operations.
The Pressing Need for VOC Reduction
Volatile Organic Compounds are a major component of industrial emissions, contributing to ground-level ozone formation, smog, and posing serious health risks. From the solvents in inks used in flexographic printing and rotogravure printing to the cleaning agents in various package & printing operations, VOCs are released into the atmosphere throughout the production cycle. The urgency to address these emissions is underscored by evolving Air Pollution Control Regulations in flexible packaging and global directives aimed at Controlling VOC Emissions from Flexographic and Rotogravure Printing.
Historically, packaging industries have grappled with the complex task of Control of Volatile Organic Compounds from Printing Operations. The challenge lies not only in achieving compliance but also in doing so in a way that is economically viable and truly sustainable. This is where DEC's expertise shines.
DEC's Holistic Approach to VOC Abatement
DEC, with its deep-rooted history in technical innovation, has dedicated itself to developing sustainable VOC emission control technologies. DEC's approach is comprehensive, addressing the entire spectrum of Emissions Management - Industrial VOC air filtration and treatment.
Addressing Existing Stationary Sources
The challenge of Control of Volatile Organic Emissions from Existing Stationary Sources is a significant one for many established printing and packaging facilities. Retrofitting older plants with efficient VOC abatement systems requires careful planning and expertise. DEC's solutions are designed for adaptability, allowing for seamless integration into existing infrastructure while maximizing VOC abatement efficiency.
VOC emission control is mandatory in several countries, with specific limits at the stack of every industry. In this document we will cover the specific needs and solutions for the flexible packaging sector.
The Industrial Emissions Directive (IED) is a European Union directive that sets limits on VOC emissions from industrial processes. The IED includes a Best Available Techniques (BAT) Reference Document (BREF) for the flexible packaging sector, which outlines the best practices for controlling VOCs.
The US Clean Air Act (CAA) is a federal law that regulates air pollution in the United States. The CAA includes a number of provisions that address VOC emissions.
There are a number of VOC emission control technologies that can be used in flexible packaging manufacturing, to comply with environmental regulations.
Tailored Solutions for Diverse Printing Processes
Flexible packaging converting presents unique challenges due to the variety of solvent-based inks (mono and multi solvent), varnishes, coatings and adhesives used. DEC's VOC abatemnt systems are specifically engineered for these applications, providing efficient abatement. When considering choosing the Best VOC Systems for Rotogravure Printing, DEC processe stand out for their efficiency, versatility, and environmental benefits.
DEC provides comprehensive assessments to identify and quantify VOC emission sources, enabling the implementation of precisely tailored VOC emission control strategies. This includes understanding the specific solvent types and concentrations to recommend the most effective abatement technology.
Beyond regulatory compliance, DEC helps companies integrate sustainability into their operations, providing Key Sustainability Facts for flexible packaging converting, proposing solutions to lower their carbon footprint, to contribute to a greener industry.

DEC stands as a testament to the power of innovation in addressing critical environmental challenges. Their commitment to sustainable VOC emission control technologies provides industries with the tools they need to achieve cleaner air, healthier communities, and a more sustainable future.
The most performing technologies include:
SRU™ • Solvent Recovery units
SRU, Solvent Recovery Unit (also known as SRP, Solvent Recovery Plant) is a gas phase VOC adsorption system, based on activated carbon, complete of onsite desorption technology, typically employed as VOC Emission Control, allowing to respect VOC emission limits with a typical efficiency up to 99%, while recovering the solvents for direct reuse, at a fraction of their purchase cost, generating a very interesting ROI (a sustainable technology and a true path to decarbonization). They can cover from small to large SLA (solvent laden air) volumes and deal with a wide variety of VOCs, including water-miscible, non-water-miscible solvents.
XTO™ • thermal oxidizers
RTO, Regenerative Thermal Oxidation works by burning VOCs at high temperatures in a closed combustion chamber: through the oxidation reaction VOCs are converted to GHG (green house gasses, CO2, NOX, CO, and H2O). The heat generated during the combustion process is then captured and used to preheat incoming air (SLA, solvent-laden air), which in turn reduces fuel consumption and enhances energy efficiency compared to traditional thermal oxidation methods. The multi-tower design of RTO allows for continuous operation. Please note that catalytic oxidation is generally not applicable in flexible packaging, being the catalyst may be poisoned by some chemicals in the VOC emissions, which can make it quickly ineffective. Please note that catalytic oxidation is generally not applicable in flexible packaging, being the catalyst could be poisoned by some compounds in the chemicals (e g. inks, varnishes, lacquers, adhesives, etc), which can make it quickly ineffective. Any thermal oxidation processes will dramatically contribute to increasing your GHG (green house gasses) emissions and your fuel consumptions.
conclusions
Selecting a VOC emission control technology that is appropriate for your specific needs and that will help you to comply with VOC emission regulations while minimizing the overall environmental impact (as VOCs and GHGs), avoiding any form of greenwashing. You have to consider different factors, including the type of VOCs being emitted (type of solvents used), the size of the facility (quantity of solvents used per year), the area available for the installation and the budget (CAPEX) constraints for the selected VOC abatement system.
However, even if all of the VOC Emission Control Technologies listed above are effective in complying with VOC regulations, only SRU, Solvent Recovery Unit technology is aligning with both environmental compliance requirements and environmental responsibility. SRU, Solvent Recovery units offer a sustainable and efficient solution for DECarbonization and circular economy implementation. By capturing and reusing solvents that would otherwise be wasted, these VOC emission control systems not only reduce the environmental impact of the Flexible Packaging industries but also contribute to cost savings (ROI) and regulatory compliance. Compared to thermal oxidation systems, Solvent Recovery units demonstrate superior energy efficiency, reduced GHG emissions, versatility, and a commitment to long-term sustainability (reduced resource consumption). Embracing such innovative technologies is crucial for industries to meet their environmental goals, drive sustainability (economic growth and environmental stewardship), and pave the way for a greener future.
