india's urban poor have no access to clean water and sanitation

According to NITI Aayog, 70% of our water is contaminated

India is currently ranked 120th among 122 countries in the global water quality index.

Rural India, which accounts for more than 60% of the total population, has no access to  sanitation systems.

Effective Sanitation Coverage in India extends to less than 12% of the population. 

crop residue Management


India Produces over 500 million tonnes of crop residue annually.

Of this, nearly 93 million tonnes are burned, 20 million tonnes every year in Punjab alone. Crop burning is a major contributor to smog, particularly in the National Capital Region.

faecal sludge treatment plants


What is an FSTP?

A faecal sludge treatment plant, or FSTP, as the name suggests, is a processing facility for the treatment and disposal of human waste,which typically consists of urine and faeces. 

An FSTP can treat septage, which is the human waste which accumulates in a septic tank over a period of time; it can also treat sewage sludge, which is the residual organic matter which is left over after a conventional sewage treatment process. 

In some case, FSTPs can even be optimised to deal with fresh human waste.

Our Proprietary Process: Co-digestion of faecal matter with agri biomass

Biomethanation is a naturally-occurring process by which organic matter is converted into gas. Co-digestion refers to the use of more than one type of organic matter within the digester vessel. Co-digestion allows for a better nutrient balance for the bacterial culture to work upon. Higher quantities of gas are produced in a shorter time.

Solutions for Local Bodies and Real Estate Sector

Madon Applied Sciences LLP (MAS) is an environmental engineering start-up company. We design and build Faecal Sludge Treatment Plants (FSTP) operating on our proprietary process of Anaerobic Co-digestion. Our solution utilises faecal sludge and septage from septic tanks along with supplementary biomass such as crop residue, horticulture residue and food waste. 

MAS FSTP technology can be scaled to meet the requirements of a community of 200 households, or for cities as large as 1 million people. The resource recovery in the form of energy (biogas and/or electricity) and organic fertiliser ensures that the FSTP functions as a profit centre. Instead of conventional sewage treatment solutions which always cost money, MAS FSTP technology makes money. 

MAS' faecal sludge and septage management solutions comply with extant laws such as the FSSM Policy 2017 and Municipal Solid Waste (MSW) Rules 2016. 

Current pipeline of FSSM projects extends to the states of Maharashtra, Punjab, Haryana, Andhra Pradesh and Telangana.
