The pollution of laundry wastewater is dependant on the origin of linen, soil degree of linen and laundering process. It is caused by dissolved organic and inorganic substances, as well as sedimented and toxic substances. In this research a moving bed biofilm reactor (MBBR) was used with active biomass colonised onto polyethylene carriers. Processes using attached biofilm in comparison to classical procedures with suspended biomass enable higher efficiency and stability of the process, especially at lower temperatures and high fluctuating loads.

Although laundering is an energy intensive process we can minimize the energy consumption by accurately specifying washing conditions. The aim of this research was to determine the influence of laundering procedures on the ecological parameters of wastewater and the electric energy consumption. Laundering procedures were simulated in a laboratory washing machine by varied laundering conditions.

The main aim of washing laundry is to remove soils and microorganisms from infected as well as dirty textiles and attain clean, fresh and disinfected textiles ready for use. Dirty textiles may contain many types of microorganisms that may be pathogenic depending on the origin of textiles. The aim of this study was to compare the disinfection effect of three disinfection agents (sodium chlorate (I), a combination of peroxyacetic acid and hydrogen peroxide, and hydrogen peroxide alone) in washing procedures at low temperature (30 °C).

The research project of the EU FP7 entitled: “Sustainable Measures for Industrial Laundry EXPANSION STRATEGIES: SMART Laundry-2015 with the acronym SMILES has the aim to design a smart laundry through research, further development and adaptation of sustainable technologies with its practical utilisations (combined for green sites or individual for existing plant augmentation). These include water reduction, energy savings, green fuel substitutions for CO2 reductions, new energy systems and improved sequencing of the process and greater textile hygiene.

The research project entitled: “Advanced CO2 Cleaning as an Ecological Process Technology’’ with the acronym ACCEPT has a main aim of improving and promoting a competitive, sustainable, hygienic, environmentally and labour-friendly carbon dioxide based cleaning technology to replace the conventional hydrocarbon and halogenated organic solvents. In the first period the research focused on the impact of CO2 inactivation towards bacteria and fungi. The germicidal effect was investigated with pure LCO2 under different working conditions (pressures, treatment and decompression times).
