Environmental Protection Technologies
Reduction technologies of PFASs input to the environment
Per- and polyfluoroalkyl substances (PFASs) have been widely used in industry and consumer products such as in coatings for textiles, paper products, cookware, firefighting foams, photographic imaging, construction, electronics, and aviation industries. PFASs are highly persistent, including their high resistance to biological degradation. Thus, if PFASs are not adequately used or treated, they may be emitted into the environment and accumulate in the environmental compartments (including soil and freshwater), posing a risk to human health. It was already evident that PFASs have been linked to many harmful health effects, including cancer, liver damage, and hormone disruption. Since February 2023, around 200 PFASs will be banned based on EU regulations. Due to PFASs’ unique properties, and high risk, even at environmental concentrations in the ppb or ppt level, it is necessary to have good control of PFASs. Reduction of PFASs using environmental protection technologies is essential in the PFASs control mechanism.

Impact of syngenetic elements of lignocellulosic feedstock on adsorptive features of biochar
The growing demand for organic products in the market promotes their use in various fields. One of such products is biochar. It was found that for the climate change mitigation the biochar production from lignocellulosic biomass has higher potential rather than biomass combustion for energy generation. Among the innovative environmental applications, biochar has the potential as an adsorbent for retaining contaminants in environmental engineering and agrotechnical systems. Artificial modification of biochar can improve its adsorption capacity, however, indirect/natural change of biochar composition (e.g. contaminated biomass) based on syngenetic elements provides prospects for new applications of biochar as well as decreases the modification costs.
