Perforated Bags – As optimum flow of air is a key point in the composting, these bags plays vital role. They serves purpose of allowing aeration to the mixture (Garbage + Culture) unloaded. According to the study, we requires to provide more than 30 % open area in order to avoid the foul smell. The bags are made with shade net (50% open area) stitched to the MS ring (FRP coated) with the help of thread. MS rings are of 18 inch diameter. There are 3 rings attached at a distance of 1 feet between each ring. The reason to use 18 inch diameter ring is, the air can reach up to 9 inch distance from the outer surface. So to avoid the anaerobic composting, the diameter of bags should not exceed 18 inch.
