You say that you are in Karnataka and that you have a registered association. Under which Act is your association registered, under the Societies registration act or under the Karnataka Ownership Flats Act? You may be having bye-laws. Do the bye-laws say anything about the disposal of garbage? Are you in Bangalore City or in any other city in Karnataka? Generally the municipalities are responsible for the ultimate disposal of garbage.
The present arrangement in Mumbai city is like this: There are specific spots not very far away from the buildings, where the Societies should make arrangements to dumb the waste. The municipality will make arrangement for their further disposal. Previously there was a scheme, probably the brainchild of Advocate Agrawal, called Advanced Locality Management (ALM). Under the scheme each housewife should segregate the waste generated in the household into bio-wastes and non-bio-wastes. Bio-wastes are those which can putrefy and give smell like kitchen wastes. Non bio-wastes are wastes like paper. The service person of the Society like the sweeper engaged for the purpose will carry them to the Municipal dump and dump them separately. The Municipality had separate schemes for the disposal of the two categories.I knew from the very beginning that it was a Tuglakian scheme. Tuglakian means something which is excellent in principle but impossible to practice. The scheme presupposed a high degree of discipline and knowledge on those responsible to put ALM into the practice, viz the Society Managing Committee, the housewives and the sweepers. Besides that they have neither the knowledge nor the discipline, each one will not obey the other one in the line of command. What happened? The Societies were fined. The Secretaries paid the fines. It was not their own money in any case. The housewives could not bother less. They did not know the Society was paying and didn't have the time to realize that it was their money. The sweeper gets his or her salary. The Society will dare not cut their salaries. After a few impositions of fines here and there, the scheme died a natural death. In a country where a simple thing like prevention of littering or urinating on the wayside could not be prevented, how do a sophisticated scheme like ALM can work?
You sit down and think how in practical terms your problem can be solved. Who is the person or authority who is not taking appropriate action? Is it your Secretary? If so, if you were the Secretary what action would you have taken? Will you dump the waste near another person's car or is there an isolated place? Who is responsible for the ultimate disposal of waste, like say, the Municipality and what is their scheme?
If you can find answers to these questions you have solved your problem.
