Eco-friendly Ganeshotsav in Bengaluru: idols, celebrations and visarjan

A natural river clay from Maharashtra, used unfired and air-dried. It dissolves back into water, so the idol returns to soil instead of settling as debris.

As eco-friendly as idol material gets. The open question is always the paint on top, which is why this page keeps asking about pigments.

Yes. It starts softening within minutes, and a household idol dissolves within a day or two.

Plaster of Paris and fired terracotta look similar and never dissolve. An idol that has not softened after a day in water is one of those two.

Depends where you are. Position as of 31 August 2026.

Maharashtra: making and selling PoP is allowed. Idols up to six feet go to artificial tanks, over six feet may go to natural water.

That is the High Court order of 24 July 2025, which the court confirmed on 20 August 2026 holds until it rules. Judgment is reserved and could land mid-festival.

Pune is stricter: no PoP in natural water at all, and a red circular oil-paint mark on every PoP idol.

Bengaluru bans PoP outright, down to making and selling it.

A clay idol is compliant in all three.

Cities publish locations two to three weeks before the festival: Mumbai as a BMC pond list, Pune via the PMC Care app, Bengaluru by QR code from the Greater Bengaluru Authority.

This page carries the year-stamped list, marked when it is still last year’s. Ward offices and helplines have the same by phone in the festival week.

Yes, for a clay idol up to about a foot and a half.

Remove the flowers first, immerse in a bucket, let it dissolve over a day or two, then pour the clay water into a garden or pot, never a drain.

Bengaluru’s civic authority recommends exactly this. The how-to above walks through it.

Do not immerse it in a lake, river or the sea.

Either immerse it symbolically at home, a brief dip and retrieve, and reuse it next year, or hand it to your city’s post-festival idol collection for managed disposal.

Reusing the same idol every year is the least wasteful option there is.

The kalash collects nirmalya: the flowers, garlands, durva and leaves that come off the idol before immersion, composted afterwards.

Pune alone keeps over a hundred tonnes out of its rivers this way each festival.

No idol, plastic or thermocol. Hand it over before you reach the water.

The material is contained and processed instead of settling in a lake: clay recovered, PoP to managed disposal.

In Pune, Punaravartan returns the collected clay to artisans for next year’s idols.

The pond is not a lesser visarjan. It is the one the courts are steering the festival toward.

Yes. Let the clay settle, pour the water into plants, and put the clay in a garden bed or planter.

A seed idol goes straight into a pot and grows. In Pune, Punaravartan collects immersed clay and returns it to artisans.

As of August 2026: kits Rs 499 to 1,499, seed idols Rs 249 to 900, a 12-inch shadu household idol Rs 2,500 to 3,500 in Mumbai and less in Pune, premium paper mache from Rs 7,500.

A clay price that looks too good is usually PoP.

A broken clay idol immerses at home like an intact one. A broken PoP idol goes to the post-festival collection, not into water.

If it breaks before the festival, most sellers replace early orders. One more reason to order early.

Monday 14 September 2026, puja around midday.

Household visarjan days: 15 September (1.5-day), 16 (third), 18 (fifth), 20 (seventh), and Anant Chaturdashi on Friday 25 September.

Some sites say 15 September for Chaturthi. The tithi starts the evening of the 13th; the puja day is the 14th.

Bulk shadu (25 to 50 kg sacks) comes from clay suppliers in Pune and Mumbai, and from craft suppliers online.

This page lists finished idols and kits. A local pottery studio can usually point you to its clay supplier if you ask.
