MICRO-POSITIVE PRESSURE AERATION FOR WINDROWCOMPOSTING OF MUNICIPAL SOLID WASTE IN CHANDIGARH:AN OPPORTUNITY IN A CARBON CONSCIOUS WORLD FORCOMBATING CLIMATE CHANGEVISHAL SHARMAAbstract The present study was a pilot project initiated in Chandigarh to discuss the feasibility andeffectiveness of adept schemes for successful co-composting of green waste and kitchen waste(food and fruit) waste in 64 m2 open covered windrows with bulking grass layer bottom upventilation system generating micro-positive pressure, making windrow piles aerobic, organolepticwith reduced green -house gases (GHGs) emission. The compost temperature profile shows twothermophilic peaks; first in bioreactor (74 oC) and second in charging pit (76.2 oC) after 40 days oninoculation and the high temperature fermentation was maintained for 80days. The high qualityfinal compost has 40oC temperature, 7.6pH, 42% moisture content, 3.36ds/m electrical conductivityand 25 C/N ratio. The main objective of the present study is to analyze and overview theconfiguration technology and analytical parameters to limit the global temperature rise to 1.5 oC,to meet the goals of the Paris agreement to avoid catastrophic impacts of climate change. Theinference of the study is the mitigation of carbon leakage, generating 346.7 carbon credits and 564quintals organic compost worth 25 lakhs to achieve sustainable zero waste future. |
