Every industrial sector produces different emissions. We analyse and measure them, and design the right system to treat them, whether it involves recovering a valuable solvent or breaking down a difficult VOC. In over 40 years, we have installed more than 900 systems in over 50 countries, across sectors ranging from flexible packaging to pharmaceuticals, from chemicals to industrial waste treatment. Understanding the specific process requirements of each sector is an integral part of the Donau Carbon Technologies design methodology.
In flexographic and rotogravure printing lines, we recover ethyl acetate, alcohols and MEK through modular SRU systems custom-engineered for each plant layout. Purified solvent returns directly to production, eliminating the cost of virgin solvent purchasing, reducing CO₂ emissions to zero and ensuring compliance with the most stringent regulatory limits. Typical payback is between 1.5 and 3 years.
Find out moreWe design RTOs and SRUs for processes involving complex VOCs, benzene, BTX, cumene and chlorinated hydrocarbons in ATEX-classified environments with stringent safety requirements and often variable flow rates. We integrate LEL control systems, paramagnetic analysers and dedicated PLCs, and also carry out revamping and retrofitting of existing third-party installations that no longer comply with current regulatory limits.
Find out moreWe recover acetone, ethyl acetate and IPA generated by pharmaceutical synthesis and coating processes, bringing them to purity and ready for direct reuse in the production process. Our plants are designed for highly regulated environments: ATEX compliance, continuous monitoring of critical parameters, integrated safety systems and full technical documentation, including traceability of every component.
Find out moreWe install regenerative and recuperative thermal oxidisers to treat intense odours and VOCs generated by industrial frying, flavours and fragrances rendering and extraction processes characterised by discontinuous flows, variable concentrations and some of the most stringent regulatory limits of any sector. Our solutions are engineered for operational reliability even under the most critical conditions, with minimised NOₓ and CO emissions and documented compliance with applicable thresholds.
Find out moreWe install SRU plants up to 150,000 Nm³/h for the selective recovery of toluene and plasticisers, managing both the ducted and diffuse emissions that characterise these production processes. Our solutions are scalable and BAT-compliant: designed to recover the economic value of the treated solvent and to adapt to evolving production mixes without requiring structural modifications to the plant.
Find out moreWe design thermal oxidisers integrated with wet scrubbers and bag filters to treat complex gas streams: VOCs, odours, HCl, SOx and fine particulates generated by industrial waste treatment. The variable composition and discontinuous operating conditions of these processes require flexible plants and advanced control systems: we design all of this while ensuring regulatory compliance even under the most critical conditions.
Find out moreRegulatory requirements enter the plant architecture from day one. We engineer to applicable European directives, local standards and site-specific requirements, not as a final constraint to be met, but as the starting point of the engineering. The result is a plant that is compliant from the first line of calculation, with no technical or legal surprises during its operational life.
Donau Carbon Technologies has held ISO 9001 certification since 1998. Our plants are designed to comply with all applicable regulations depending on country and context: European directives (IED, ATEX), ASME standards, and local safety and emission requirements. Compliance is not an add-on, it is built into the design from day one.
