my cleanliness statistics - 2 - Priya Ubale

Priya's responses are after the >>>>.
8000 tons of waste generated daily.
    - 2000 T of this is construction waste.
    - 35% of balance waste by weight is dry waste i.e. 2000 tons approx.
    - and balance is wet waste (food) i.e. 4000 tons approx.
60% of non-construction waste by volume is dry waste and handling, storage, landfill space costs are determined by volume.
>>>> I am quite sure that this is incorrect. In the past 4-5 yrs since I have 'worked' in this field it has magically increased from 6000 to 7000 tons and now they / u say 8000. The acceptable figure is 7000 tons of waste daily of which 40-45 % is 'wet' 10-20% is 'dry' and again 40-45% is Inert. Certainly not 1/4 as given above!
500 gm waste is generated per person per day (650 gm by rich people, 300 gm by poor) x 5 people / family = 2.5 kg waste / day / home.
>>>> Again this is wrong. Just think abt it.... How many kilos of subzi do u eat in a day? How many packets do u open per day? Can u really generate 500 gms yourself. Speak to Jyoti abt this. She shares this apprehension totally. Also our ALM study calculates an average of 345 gms of waste per family excluding inert. My maths is bad but if u add 40% more per that family as inert it is still less than 1 kg per family and nowhere near 2.5 kgs!!
On this basis, lot of things can be calculated. >>>> On a good index a lot of things can be calculated, certainly. But when the norm itself is , if I may say so, fudged bt the authorities to make certain projections to suit lobbies then what can one say? -- bin sizes, trucks needed, possible cost savings, etc.
Rs. 140 cr is spent on transporting garbage.>>>> 1.25 crore per day is spent on waste collection and disposal. Rs. 1.60 per kag of waste...
60% people live in slums. Generate 50% of the garbage.
>>>> Tho this is the accepted norm I question this too. How can 8% land accomodate 60% people, all of it horizontally???
It takes 30 days in theory to vermi-compost, 45 days in practice. >>>> Sometimes more. Other systems need less. But vermiculture is the most env-friendly 
This is needed to calculate pit size.
Mumbai has 1800 km roads - 1200 km are cleaned daily by BMC staff, 600 km are cleaned daily through outsourcing.


It is one of the beautiful compensations of this life that no one can sincerely try to help another without helping himself. --Charles Dudley Warner
