“…The addition of NO x to the atmosphere possibly might enhance the formation of polar stratospheric clouds that activate chlorine-catalysed destruction of ozone and increase ozone in the troposphere [63]. Ground level ozone, or tropospheric ozone, is harmful for human health and is formed by the action of sunlight on ozone precursors, such as nitrogen oxides, VOCs methane and carbon monoxide [64][65][66], compounds that are related to the extraction and burning of fossil fuels [67,68]. Another category where a high impact is observed, is "Terrestrial ecotoxicity".…”

In the last twenty years, research activity around the environmental applications of metal–organic frameworks has bloomed due to their CO2 capture ability, tunable properties, porosity, and well-defined crystalline structure. Thus, hundreds of MOFs have been developed. However, the impact of their production on the environment has not been investigated as thoroughly as their potential applications. In this work, the environmental performance of various synthetic routes of MOF nanoparticles, in particular ZIF-8, is assessed through a life cycle assessment. For this purpose, five representative synthesis routes were considered, and synthesis data were obtained based on available literature. The synthesis included different solvents (de-ionized water, methanol, dimethylformamide) as well as different synthetic steps (i.e., hours of drying, stirring, precursor). The findings revealed that the main environmental weak points identified during production were: (a) the use of dimethylformamide (DMF) and methanol (MeOH) as substances impacting environmental sustainability, which accounted for more than 85% of the overall environmental impacts in those synthetic routes where they were utilized as solvents and as cleaning agents at the same time; (b) the electricity consumption, especially due to the Greek energy mix which is fossil-fuel dependent, and accounted for up to 13% of the overall environmental impacts in some synthetic routes. Nonetheless, for the optimization of the impacts provided by the energy use, suggestions are made based on the use of alternative, cleaner renewable energy sources, which (for the case of wind energy) will decrease the impacts by up to 2%.

“…This group of chemicals evaporates easily from fluids or solids at room temperature. VOCs can have natural or anthropogenic origins and occur for example in agriculture, in many industry branches, in traffic and also in common household products, for example, in paints, adhesives, cosmetics and cleaning agents [4,5].…”

In recent years the degree of automation in life science laboratories increased considerably by introducing stationary and mobile robots. This trend requires intensified considerations of the occupational safety for cooperating humans, since the robots operate with low volatile compounds that partially emit hazardous vapors, which especially do arise if accidents or leakages occur. For the fast detection of such or similar situations a modular IoT-sensor node was developed. The sensor node consists of four hardware layers, which can be configured individually regarding basic functionality and measured parameters for varying application focuses. In this paper the sensor node is equipped with two gas sensors (BME688, SGP30) for a continuous TVOC measurement. In investigations under controlled laboratory conditions the general sensors’ behavior regarding different VOCs and varying installation conditions are performed. In practical investigations the sensor node’s integration into simple laboratory applications using stationary and mobile robots is shown and examined. The investigation results show that the selected sensors are suitable for the early detection of solvent vapors in life science laboratories. The sensor response and thus the system’s applicability depends on the used compounds, the distance between sensor node and vapor source as well as the speed of the automation systems.

Organic solvents have been frequently and excessively used in the printing process for a long time. The use of organic solvents in solvent-based ink is responsible for fire hazards, volatile organic compounds emission, and high manufacturing cost during printing. The present study aimed at replacing solvent based ink with water-based ink for reducing the volatile organic compounds emissions and carbon footprints in gravure printing without affecting overall printing quality. The PET film was printed with a water-based ink laser engraved cylinder having reduced cell depth and it resulted in the transfer of a low volume of inks on printing substrate. The cost of printing one kg of polyester film with water-based ink was reduced by US$ 1.95 compared to solvent-based ink. The volatile organic compounds emissions for water-based ink were measured at 2478 ppm against 3373 ppm for solvent-based ink. The water-based ink reduced the carbon footprint by 3.04 kg, which was equivalent to CO2 during printing of one kg polyester film used for making flexible pouches compared to solvent-based ink. The outcome of this study may be the benchmark to authorities for green manufacturing systems in gravure printing applications for the betterment of the environment and humanity.
