    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.

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

    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.

  5. Nithya says:

    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!

    • rumi says:

      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. Meera K says:

    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.

  7. Meera K says:

    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!

  8. Sneha says:

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

  9. Shree D N says:

    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.

Taking flight: Does Chennai need a second airport and at what cost?

Civic and environmental activists question the feasibility of the greenfield airport in Parandur and suggest expansion of Chennai airport.

Ten lakes, two streams, 3,500 acres of agricultural land, 1,005 families and hundreds of plant and animal species — these are all under threat because of one development project.

Explainer: Electrical components and ways to increase BESCOM sanctioned load

Here is an explainer on electrical system components and its maintenance, how to calculate sanction load and the process to increase it.

(Part 1 covered the components of BESCOM bill, tariff structure and sanction loads. Part 2 delves into electrical system maintenance) With the adoption of electric vehicles, owners are tapping into their existing meters to charge their vehicles, leading to electrical mishaps. If you need to connect a 3.3 kw/7.2kw EV charger, your sanctioned load needs to be enhanced. This leads to cable/wire, MCB (miniature circuit breaker) and RCCB (residual current circuit breaker) replacement, possibly the energy meter too may need to be replaced.  Overall, if every household enhances sanction load, this leads to constant tripping of the transformer and short…
