OED (Odour Eliminator & Decomposer) is a scalable indigenous microbial bio-solution that eliminates landfill odour, accelerates decomposition, reduces methane and restores biological activity to waste ecosystems.

How fast does OED remove odour?

Foul smell is typically neutralised within 2-5 minutes of application, with 95% odour control on day one and 100% within a week.

Where has OED been deployed?

OED has been deployed across 15 municipal corporations in Maharashtra, Odisha, Jharkhand, West Bengal, Assam and Eastern India, and with private clients including UltraTech Cement, Dalmia Cement, ACC Cement and Reliance Bio-Energy.

Controlling RDF odour in cement plants — without downtime

Refuse-derived fuel releases persistent odour and toxic gases. A biological layer neutralises it inside live operations.

Why RDF smells

Refuse-derived fuel (RDF) is a mixed, organic-rich feedstock. Stored and handled at a cement plant, it releases methane, hydrogen sulphide and ammonia — an odour and worker-health problem with no scope to pause fuel operations.

Fogging a bio-film

OED is fogged and sprinkled across RDF storage and handling zones at roughly 1 litre per tonne, forming a protective bio-film that neutralises odour-causing gases and reduces the smell of fresh incoming waste.

In practice

At UltraTech Cement (Manikgarh and Rawan), smell was neutralised within 1–2 minutes of application. After about a month of regular dosing, the plant atmosphere stayed largely free of harmful gases — with zero operational downtime.
