Udyogamandal: The Story of Kerala’s Industrial Township

Key facts

FACT was incorporated in 1943 at Udyogamandal and began producing ammonium sulphate in 1947.
FACT was promoted by the Seshasayee Brothers, backed by Travancore’s Diwan Sir C. P. Ramaswami Iyer; it became a public-sector company in 1960.
Udyogamandal lies in Eloor municipality, an island of about 14 km² between two branches of the Periyar.
Travancore-Cochin Chemicals (1951) and Hindustan Insecticides’ Udyogamandal unit (1957) followed FACT into the township.
Greenpeace named Eloor one of the world’s toxic hotspots after studies that began in 1999.

An “unheard-of village” chosen for a fertiliser plant

FACT’s own history credits Sir C. P. Ramaswami Iyer, Diwan of Travancore, with clearing the way for a fertiliser plant in what it calls a “till then unheard of village” on the Periyar. The promoters were the Seshasayee Brothers, and the company was incorporated in 1943. The motive, FACT says, was food self-sufficiency after the Bengal famine. Production of ammonium sulphate began in 1947 – first using wood as the raw material for gas, later naphtha.

The new place needed a name, and Udyogamandal (from *udyogam*, industry, and *mandalam*, area) stuck. It is not a separate municipality; it is part of Eloor, a river island town between two distributaries of the Periyar.

How the township filled up

1947 – FACT’s ammonium sulphate plant starts; capacity is expanded in stages up to 1972.
1951–54 – Travancore-Cochin Chemicals incorporated; caustic soda from January 1954.
1957 – Hindustan Insecticides opens its Udyogamandal unit.
1960–62 – FACT becomes a public-sector company, with the Union government the major shareholder from 1962.
1965–66 – FACT adds an engineering consultancy (FEDO) and a fabrication division, FACT Engineering Works.
Later decades – a wider estate of chemical, rare-earth and allied units grows along the river towards Edayar.

Around the plants came housing for employees, schools, shops and bus routes, which is why older residents still talk of “the FACT township”. Many families in Kalamassery have a parent or grandparent who worked there.

Why Eloor, of all places?

The island position helped. Plants could draw water from one branch of the Periyar and were close to the Kochi port by water and, later, by road through Kalamassery. Hydroelectricity from Travancore’s Pallivasal scheme (commissioned around 1940) made power-hungry chemistry possible – very likely part of the reason the Alupuram aluminium smelter was also built nearby. When power became expensive decades later, several energy-heavy units struggled, a pattern you can read in the story of the belt’s mills and factories.

The other side of the story

Concentrated chemical industry on a drinking-water river has a cost. Environmental groups and journalists have documented coloured discharges, fish kills and health worries for decades. Greenpeace’s studies from 1999 led it to call Eloor a global toxic hotspot, and in May 2024 a large fish kill downstream of the Pathalam regulator was investigated by the Pollution Control Board. Any honest history of Udyogamandal includes both the jobs and these concerns.

Udyogamandal today

FACT is still the largest presence. It is a working public-sector company with a training and apprenticeship stream – see our FACT Udyogamandal guide for practical details. FACT’s Cochin Division at Ambalamedu, near Tripunithura, is a separate site, so check which one your letter names. The roads around Udyogamandal are busy with tankers at shift change, and the riverside is industrial rather than scenic. For the wider picture, read mills and factories around Kalamassery and how Kalamassery became an industrial town.

If you are joining a plant at Udyogamandal

Some trainees and contract engineers prefer not to live in the industrial zone itself. Kalamassery, across the river, has more food options, the railway station and the metro. Ashraf Gents Hostel is a boys’ hostel and PG on NAD Road, at the signal, Kalamassery, taking students, staff and working men only. Check the bus or two-wheeler route to your gate at your actual shift times before deciding.

Indicative rent from the hostel’s public profile is about ₹2,000–3,000 per head per month, negotiable, with one month’s advance – confirm on +91 90746 23855. Look at the rooms on the home page.
