The intensive development of the polyurethanes industry and limited resources (also due to the current geopolitical situation) of the raw materials used so far force the search for new solutions to maintain high economic development. Implementing the principles of a circular economy is an approach aimed at reducing the consumption of natural resources in PU production. This is understood as a method of recovery, including recycling, in which waste is processed into PU, and then re-used and placed on the market in the form of finished sustainable products.

- - This study explores using wheat straw-derived biochar (BC) to reduce nitrogen levels in landfill leachate (LLCH) and ammonium chloride solutions, with BC performing better in nitrogen adsorption (95.08%) compared to commercial activated carbon (93.11%).
- - Laboratory tests showed BC's effectiveness might be due to its higher carbon content, but its lower performance with LLCH is likely due to the complex chemical makeup of leachate, necessitating the use of various adsorption models for analysis.
- - The research indicates that biochar demonstrates significant potential for treating landfill leachate, suggesting further investigation into other biochar materials could help tackle environmental issues related to waste disposal.
