Frequently asked questions

Quick answers

What is a smokeless incinerator?

A smokeless incinerator burns waste at controlled high temperatures and cleans the exhaust before release. Stree Sanman’s INCECO uses an electrically heated primary chamber (about 800 °C) and secondary chamber (about 1000–1050 °C), followed by a water scrubber, activated carbon and a patented corona-discharge smoke absorption unit.

What types of incinerators does Stree Sanman make?

Stree Sanman’s INCECO range covers biomedical waste (BMW) incinerators for hospitals and labs, municipal solid waste (MSW) incinerators for municipalities and grampanchayats, sanitary napkin incinerators for schools, offices and public toilets, and animal carcass and dead poultry incinerators for farms and veterinary use. We also supply pyrolysis and gasifier machines for waste-to-energy.

How does Stree Sanman purify air?

At source, ECOFILT flue-gas filtration cleans emissions from industrial stacks, incinerators and crematoria before they leave the chimney. For ambient air, eTree active outdoor purifiers clean the air people breathe in cities, on highways and on campuses, with live O₂, PM2.5/PM10 and CO₂ monitoring.

What STEM education products does Stree Sanman offer?

Stree Sanman brings hands-on science learning to schools, colleges and government institutions through Planetarium domes for astronomy and space science, and Sparkboard for interactive classroom STEM learning. Both can be funded as CSR education programmes.

How does Stree Sanman help us choose the right waste disposal machine?

We start with a waste and emissions assessment of your site: waste types, daily volume, space, power and the rules that apply. We then recommend the right technology and capacity (incineration, pyrolysis or air-pollution control), design for compliance, verify performance with a pilot, and monitor results after installation.

Can INCECO treat both municipal and biomedical waste?

Yes. INCECO is configured for municipal solid waste (MSW) and for biomedical waste (BMW), with the secondary chamber set to the temperature each set of rules prescribes. Models range from 5–7 kg to 45–50 kg per batch.

What makes Stree Sanman a research-led company?

Our products come out of in-house R&D and are protected by Indian Patent No. 422515. We test with independent institutions such as VJTI Mumbai, and we are developing a circular-carbon model in which carbon recovered from waste processing is reused as filtration media in eTree and Ecofilt.

Where can Dovey sanitary napkin vending machines be installed?

Dovey machines suit offices, schools and colleges, hospitals, hotels, railway stations, airports and public toilets. Models range from manual and push-button units to coin-operated, smart and online machines holding 25 to 99 napkins.

Can our company fund these projects through CSR?

Yes. Stree Sanman prepares CSR-ready proposals for incinerators, eTree air purifiers and menstrual-hygiene programmes in government schools, hospitals and institutions, matched to your CSR budget and Schedule VII focus areas.

Where is Stree Sanman located?

Our head office is at C-214, 2nd Floor, Eastern Business District, LBS Marg, Bhandup West, Mumbai, Maharashtra 400078. We supply and install across India and internationally.
