Analysis of the Effectiveness of Green Waste Composting under Hyperbaric Conditions

Increasing global population growth has a significant impact on waste production. The European Union (EU) focuses recycling, biological treatment, and reuse. In the case of biodegradable waste, problem is long process material decomposition so that product meets requirements national regulations EU directives. search for way to accelerate this still ongoing. This study presents composting green under hyperbaric conditions. Eight experiments, four with air exchange frequency tAE = 4 h experiments 8 were established. conducted in variants: 0 (atmospheric pressure) overpressures 50, 100, 200 kPa. They carried out same input characterized by initial moisture content 60% mass 2000 g. During all parameters obtained (moisture content, pH, loss ignition (LOI), C:N ratio, nutrient (P, K), respiratory activity microorganisms (AT4)) also evaluated. most weight composted was observed variant an overpressure kPa (tAE h). compost relation original decreased 23.7%. highest organic matter removal efficiency variants 50 100
