Understanding how to segregate waste

What do you mean by waste segregation?

Waste segregation basically means keeping wet and dry wastes separately, so that dry can be recycled and wet waste can be composted.

Why should I do it?

  1. So that it reduces waste that reaches landfills and reduces pollution to air and water
  2. So that different processes- composting, recycling, incineration can be applied to different kinds of waste

How do I practice waste management at home?

  1. Keep separate containers for dry and wet waste in the kitchen
  2. Keep two bags for dry waste collection- paper and plastic , for the rest of the household waste
  3. Keep plastic from the kitchen clean and dry and drop into the dry waste bin. Keep glass /plastic containers rinsed of food matter
  4. Send wet waste out of the home daily. Store and send dry waste out of the home , once a week.
  5. Keep a paper bag for throwing the sanitary waste

What is the first few steps to initiating waste management in the apartment complex?

  1. Form a group of like-minded people
  2. Explain waste segregation to your family / neighbours in your apartment building.
  3. Get the staff in the apartment building to also understand
  4. Get separate storage drums for storing the dry waste and wet waste.
  5. Have the dry waste picked up by the Dry waste collection centre or your local scrap dealer

DRY WASTE

What is Dry Waste?

Paper, plastics, metal, glass, rubber, thermocol, Styrofoam, fabric, leather, rexine, wood – anything that can be kept for an extended period without decomposing.

Will dry waste smell if I store it for a week?

Not if it is clean and dry. Make sure that plastic sachets of milk, curds, oil, idli batter, any food item, are cleaned of all their contents and dried before being put in the dry waste bag. Then they will not stink.

  1. Hi, which brand do you use? You can flush it down the toilet, but do check whether your plumbing system allows it. Organic stuff should be easily compostable and vermicompostable too, but you have to figure out and come up with your own systems to do it.

  2. Hi Meera K, in case of changing the cat litter, how do I dispose the used cat litter? I use the organic type.

  3. Rita Mishra,
    Used paper napkins can be put into kitchen waste, they will decompose. But they are manufactured using chemicals, so better avoid them as much as possible!

  4. Nithya,
    For cat litter, a natural organic plant­/wheat fibre-based product can be used like Cat’s Best Litter. Once used, the clumps can flushed easily (depends on type of plumbing ­ – check with your apartment). The wheat fibre based material is quite absorbent, and breaks down in water (like poop). Available online or in pet stores. The flip side is it is more expensive. But very convenient in an apartment.

    Do not use clay (bentonite) ­based litter – they are not compostable or degradable. They have to be wrapped and put into reject.

    There is also plain sawdust (cheap!) ­that may work if you have a house with some garden space. You can buy sawdust from a local wood mill or from Daily Dump Compost. There is also recycled paper-based litter but not sure where it is available.

  5. Hi all. I have a cat at home and I use clay based cat litter at home. How should this waste be disposed?

    I was storing this separately and the BBMP waste collection person refuses to collect cat litter now – I am not sure why. Please can someone help?

    Thanks very much in advance!

    • I’m facing the same problem with bbmp refusing to take cat litter .What are the steps taken to avoid.Please let me know.

  6. Is there a difference between Segregate and Sorting?
    Will my child react differently if I tell my child that “Everything is Useful.” instead of saying n “Nothing is waste?”
    Will my child’s future get wired differently if my child get’s to know that sorting and putting in ANY order (size, texture, material, colour, shape) adds VALUE (aesthetic and then comercial) to EVERYTHING.

  7. I want to ask BBMP where to put used kitchen paper napkin which are wet ……should it go in wet waste tell me plzzzz….as soon as possible ……

  8. ITC picks up plastic and paper waste from my apartment. Try contacting them.

    Are there BBMP collection centres for HHW?

  9. I have tried composting vegetable & fruits wast and vegetarian leftovers at home. It attracts too many fruit flies (even though the smell was almost zero).

    The plastic, paper, chocolate/biscuit wrappers that I collected are not accepted by the scrap dealers in my neighbourhood (even though it is offered free).

    Unless there is a solution for the above recycling plastic & pager and composting will fail.
