A waste wet oxidation technique as a solution for chemical production and resource recovery in Poland

Effective municipal solid waste (MSW) management and waste-to-resource recovery has a key potential to play a vital role in economic growth of a country. MSW contains the different items of daily use that makes its composition mix in nature. Different waste-to-energy techniques are already available to treat this waste but these techniques always require some pretreatments such pre-separation and pre-drying of mix MSW that makes these processes less techno-economic to apply on large scales. To provide an effective solution to this problem, potential wet oxidation technique has been reviewed in this study. In the first section, the statistics for MSW generation and composition for different cities in Poland have been presented to show the existence of maximum organic content which can be converted to useful organic compounds. In the later section, the wet oxidation technique and its various aspects have been reviewed in detail to justify the potential of this technique to treat mix MSW at larger scales to produce different valuable products in the context of waste-to-resource recovery.
