Wet waste in.
Common-area
power out.

A 500-flat society generates ~250 kg of wet waste daily. With segregation done at source, that runs the clubhouse, common-area lighting, and security cabin power, and dramatically cuts the society's waste-management contract.

What makes societies different

Segregation at the doorstep is the only thing that matters.

Plant economics live or die on whether residents segregate. Our setup includes resident-onboarding kits, twin-bin distribution, weekly review with the housekeeping team, and a dashboard the RWA can show in monthly meetings.

Same four-stage process across every sector, but tuned to the inputs, peaks, and outputs that matter here.

Feedstock

What goes in.

The substrate determines plant size, gas yield, and everything downstream. Here is what we typically design for in this sector.

F.01
Segregated kitchen waste
0.4–0.6 kg/flat/day
Door-to-door pre-segregated organic stream from residents.
F.02
Garden trimmings
Seasonal
Society-maintained landscaping waste, shredded for input.
F.03
STP sludge
Optional
Co-digested if society STP exists, additional yield.

Society plants typically pay back in 4–7 years (depends on subsidy access and existing waste contract).
Estimates are illustrative ranges. Site-specific output depends on feedstock quality, weather, and operating conditions.

Built around the regulations that govern societies.

Compliance is engineered in from the design stage, sensor-driven audit trails, automatic reporting, and pre-filled regulatory submissions are part of the plant, not bolted on afterward.

SWM Rules 2016
Bulk generator threshold (>100 kg/day), most mid-size societies qualify.
State PCB consent
Standard residential establishment-level consent.
RWA resolution
Society-level approval; we provide template + presentation deck.
Municipal byelaws
On-site processing typically incentivised, property tax rebates in some states.

From decision to dispatch

Five phases. Predictable.

A typical societies deployment moves through these five phases. Timelines are real, not aspirational.

01
01 / Society audit
Week 1–2
Flat-count, waste-room inspection, RWA presentation.
02
02 / Resident onboarding
Weeks 3–6
Twin-bin distribution, segregation training, housekeeping plan.
03
03 / Plant install
Months 2–4
Skid-mounted digester, clubhouse-adjacent.
04
04 / Soft launch
Month 5
Common-area uses go live; resident dashboard active.
05
05 / Continuous review
Ongoing
Monthly RWA review, segregation quality scorecard.

In their words

Residential societies already running.

A small selection of operators we work with in this sector.

"The maintenance bill went down. The compliance file got thinner. Residents stopped complaining about the waste truck."

Frequently asked

Things societies always ask.

Six questions we hear in nearly every first conversation with a societies operator.

It happens. Our onboarding program reaches 80%+ compliance in most societies within 2 months. We screen at intake, non-segregated bags go to municipal pickup, not the plant. The dashboard tracks segregation quality publicly so peer pressure does its work.
A 500-flat society plant fits in 40–60 m², typically next to the clubhouse or in an unused corner of the property. Skid-mounted designs minimise civil work.
Yes, most societies pass it via AGM or special resolution. We provide a presentation deck, FAQ document, and have our team attend the meeting if needed.
Not a problem, STP integration is optional. The plant runs on kitchen waste alone. STP integration is a 10–15% yield bonus where it makes sense.
Yes, state-level under SBM-Urban, central-level under MNRE, plus property-tax rebates in some municipalities. We help you tap whichever apply locally.
