On-site energy from
what hospitals
already throw away.

Kitchen waste, STP sludge, and biomedical-adjacent organic streams converted into clean cooking gas and digestate, with audit-grade compliance documentation built in. The plant slots into existing facilities operations without disrupting clinical workflows.

What makes hospitals different

The clinical-side segregation that makes this work.

Hospital waste streams cannot mix. Anaesthetic, pharma, sharps, and pathological waste must remain in their own colour-coded streams under BMW Rules. What our plants accept is the kitchen-side organic stream and STP sludge, already separated by your housekeeping team.

How it works · in this sector

From waste to working plant.

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

P.01
Kitchen + STP
Segregated organic streams collected daily
P.02
Pre-treatment
Shredding, slurry prep, pH adjustment
P.03
Anaerobic digester
Mesophilic, 30–35 days retention
P.04
Gas + digestate
Scrubbed biogas to canteen + slurry to landscaping
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
Canteen & kitchen waste
60–250 kg/day
Cooked food, peels, plate waste from staff and patient catering.
F.02
STP sludge
0.3–1 m³/day
Co-digested with food waste, reduces sludge disposal cost simultaneously.
F.03
Garden & horticulture
Seasonal
Leaves, grass clippings used as supplementary substrate.

Hospital plants typically pay back in 4–6 years on gas savings + sludge disposal cost reduction combined.
Estimates are illustrative ranges. Site-specific output depends on feedstock quality, weather, and operating conditions.

Built around the regulations that govern hospitals.

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.

Bio-Medical Waste Rules · 2016
Confirms organic kitchen and STP streams are separately handled, not BMW.
SWM Rules · 2016 (Schedule II)
Bulk generator obligation, hospitals >100 kg/day waste must process on-site or contract authorised handler.
State PCB Consent
Consent to Establish + Consent to Operate; we handle filings.
NABH / NABL alignment

From decision to dispatch

Five phases. Predictable.

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

01
01 / Site audit
Week 1
Feedstock measurement, space survey, regulatory check.
02
02 / DPR + design
Weeks 2–4
Detailed Project Report, plant sizing, regulatory filings.
03
03 / Construction
Months 2–5
Civil works, digester install, gas line and burner integration.
04
04 / Commissioning
Month 6
Sensor calibration, methane stabilisation, training.
05
05 / Live + monitored
Ongoing
AI yield optimisation, predictive maintenance, monthly reports.

Frequently asked

Things hospitals always ask.

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

No. Those must continue to flow to a CBWTF (Common Bio-Medical Waste Treatment Facility) under BMW Rules 2016. Our plants accept only kitchen organic and STP sludge, both already separated upstream.
Roughly 80–120 m² of footprint, including digester tank, pre-treatment bay, and gas-storage. Most hospital campuses absorb this in service-yard or behind-MEP-block locations.
Plants tolerate 30–40% feedstock variation without intervention. For longer dips (e.g. summer break at teaching hospitals) we co-feed garden waste or temporarily reduce output.
Yes, scrubbed biogas meets cooking-grade specifications. We typically pipe it to staff canteens first, with a clean transition path to patient kitchens once you have institutional confidence.
The plant generates an automated audit trail, feedstock weights, gas output, digestate disposal, that integrates cleanly into your existing accreditation evidence files.
You do. We design, construct, commission, and operate under O&M contract. Models including BOOT (Build-Own-Operate-Transfer) and OPEX-only also exist if you prefer.
