Understanding your waste generation for scientific approach of solutions

Waste Audit, method 1: Assumption method 1. Number of Households ( ) X 0.5 Kgs = ……………. Kgs/day of wet

waste 2. Number of households ( ) X 0.3 Kgs = ……………. Kgs/day of Dry

waste 3. Number of Households ( ) X 0.1 Kgs = ……………. Kgs/day of

Rejects + Sanitary waste 4. Total waste produced per day: 1 + 2 + 3 = ………….. Kgs

Waste Audit, method 2: Per capita method 1. Number of Households ( ) X 0.8 Kgs = ……………. Kgs/day of wet

waste 2. Number of households ( ) X 0.49 Kgs = ……………. Kgs/day of

Dry waste 3. Number of Households ( ) X 0.07 Kgs = ……………. Kgs/day of

Rejects + Sanitary waste 4. Number of Households ( ) X 1.4 Kgs = ………….. Kgs per day of

Waste Audit, method 3: Scientific method Step 1: Collect semi-segregated waste (Wet, Dry and Reject) from the household Step 2: Employee 2-3 housekeeping staff to secondary sort the waste into three categories Step 3: Weigh each of these and record it on daily basis Step 4: Repeat above steps for a week continuously

Background information:Is waste being segregated at a household level?Who is the agent collecting waste?How much is he being paid monthly?Is space allocated for waste management? If yes how much ( in sq.ft)List all the empty/unused spaces in your apartment (in sq.ft)Total number of gardening and housekeeping staffIs there a nearest DWCC (Dry Waste Collection Center) and where?Is there a Green committee in the association?
