Company profile

Donau Carbon Technologies Srl, was born in 1981 (former SIRI) and since then, offers to  Customers a large range of solutions and services to fulfill needs relevant to environmental matters and laws compliance related to emission limits.The Company has been operating in air treatment field for years, providing solvent recovery plants, thermal oxidation plants, air treatment plants by means of wet scrubbers and bag filters, as well as technologies for treatment and removal of organic residuals on aluminum scraps and a full range of complementary services connected with said technologies.

DCT is in constant technological development with particular attention to the safety, environment, and sustainability of out plants. 38 years of solid experience with more of 350 plants installed in the flexible packaging industry, make us a worldwide reliable partner for air treatment

Giuseppe Dell'acqua Managing Director



Our  main technologies concern the treatment of volatile organic compounds (VOC), and specially: Solvent recovery and RTO units.

  • Solvent recovery plants:

We realize solvent recovery plants with activated carbon adsorption in most different field, employing,  processes with nitrogen (employed in presence of water soluble solvent)or with steam regeneration (employed in presence of water low soluble solvents) due to our yearlong experience we developed, besides “standard” solvent recovery plants, also solutions on skid in compact and modular type. DCT installed more than 100 solvent recovery plants worldwide from 2.000 to 560.000 Nm3/h.

  • DCT new patented product: X-CSR:

DCT’s innovative plant, X-CSR, is addressed to the printing ecosystem, and aims to extend solvent recovery technology, generally adopted only by big companies, also to typographies and SMEs, producing lower volume of solvent.A polluted air flow of 15.000 Nm³/h containing a solvent content of 4-8 g/Nm³ is cleaned passing through the activated carbon bed of the ADS-101. The air solvent content is reduced to 50 mg/Nm3. The solvent adsorbed inside the ADS-101 is removed and recovered with the activated carbon regeneration with hot nitrogen gas and vacuum desorption.

  • RTO

The Regenerative thermal oxidation (RTO) allows solvent oxidation by increasing the polluted air temperature over 750-800 °C with a high efficiency heat recovery system using ceramic media. Starting from 1995 till today, Donau Carbon Technologies, with more than 300 oxidisers of this type having capacities between 5.000 and 200.000 Nm3/h, achieved very high quality and reliability levels.
