The present study discusses physicochemical methods of organic waste processing in closed biotechnical life support systems (BTLSS). Sanitary and household cotton wastes were processed by the method of wet combustion in hydrogen peroxide using an alternating current electric field – a promising physicochemical method for organic waste processing in the BTLSS. The highest efficiency of the process (in terms of power consumption, duration of the process, and oxidation rate) was achieved in experiments with oxidation of a combination of cotton fabrics and urea-containing wastes such as human urine and feces. The reason for this must be that urea is a reactive aqueous solvent of cellulose.

本研究讨论了封闭的生物技术生命支持系统（BTLSS）中有机废物处理的物理化学方法。卫生棉和家用棉的废物是通过使用交流电场在过氧化氢中进行湿式燃烧的方法处理的，这是BTLSS中用于有机废物处理的一种有前途的理化方法。该过程的最高效率（就功耗，过程持续时间和氧化速率而言）是在棉织物与含尿素废物（如人尿和粪便）的混合物进行氧化的实验中获得的。其原因必须是尿素是纤维素的反应性水性溶剂。
