Sivakasi Firecrackers: History of India's Fireworks Town, Standard Fireworks and the SWAS, STAR and SAFAL Green Crackers

Sivakasi and Deepavali crackers go together. The town in Tamil Nadu's Virudhunagar district is India's best-known centre for fireworks and safety matches, and its products reach markets across the country every Deepavali season. Today the industry is also adapting to air-quality concerns through green-cracker formulations developed under CSIR and CSIR-NEERI. This guide covers Sivakasi's history, the story of Standard Fireworks and what SWAS, STAR and SAFAL actually mean.

Note: SWAS, STAR and SAFAL are names of green-cracker formulations, not Diwali rituals, and "green" does not mean pollution-free. For buying and local rules this Diwali, see our green crackers 2026 guide.

How Sivakasi became India's fireworks town

Sivakasi's fireworks industry grew out of safety-match making in the early twentieth century; local histories credit entrepreneurs including A. Shanmuga Nadar and Ayya Nadar with laying its foundations. The Second World War disrupted imports of fireworks and raw materials, opening the market to Indian makers, and by the early 1940s firms such as National Fireworks, Kaliswari Fireworks and Standard Fireworks had become prominent names.

Several things helped the industry grow:

• Dry climate: low rainfall suits seasonal manufacturing, drying and storage.
• Skills: experience from the match industry carried over into sparklers and fireworks.
• An ecosystem: suppliers of chemicals and paper, printing and packaging firms, transporters and distributors grew around the factories.
• People: generations of workers and entrepreneurs with specialised experience.
• Distribution: a network reaching wholesalers and retailers in every state.

Sivakasi and the Deepavali season

Deepavali is the industry's biggest season, so production, packing and dispatch are planned months ahead. The range spans flower pots and fountains, sparklers, ground chakkars, rockets, sound crackers, fancy items and aerial display products. Fireworks are a popular part of modern Deepavali, but they are not its foundation: lamps, prayer, family and the victory of light over darkness are at the heart of the festival.

Standard Fireworks: a Sivakasi name since 1942

Standard Fireworks (P) Ltd is one of the established names of the Sivakasi industry. According to the company's own history (stdfireworks.in), its journey began in 1942 with a safety-match unit in Sivakasi founded by Shri Yennarkay R. Rajaratnam; it later built its fireworks business and brands and describes ongoing modernisation of its production lines.

Its published product categories include sparklers, flower pots, chakkars, rockets, sound crackers, fancy fireworks and multi-shot "cakes". Availability varies by season and place.

Standard Fireworks and green crackers: a manufacturer is not a formulation. SWAS, STAR and SAFAL came out of CSIR research, and the 2018 programme included demonstrations and work with makers in Sivakasi; that does not make every product of any one company a SWAS, STAR or SAFAL cracker. Check each pack.

What are SWAS, STAR and SAFAL?

India's green-cracker programme, led by CSIR with CSIR-NEERI, set out to cut the pollution from conventional fireworks while keeping the industry viable. In October 2018 the Government announced three formulations:

SWAS: Safe Water Releaser

SWAS releases water vapour, together with air, which acts as a dust suppressant and dilutes gaseous emissions; the launch formulation also dropped potassium nitrate and sulphur. Later NEERI work describes hydrogel-based SWAS versions, so not every SWAS product uses the same recipe. A particulate cut of about 30 to 35% was reported at launch.

STAR: Safe Thermite Cracker

STAR uses a modified, thermite-type composition (NEERI's work mentions iron oxide) to make burning more efficient, also without potassium nitrate and sulphur. A particulate cut of about 35 to 40%, with lower sulphur dioxide and nitrogen oxides, was reported at launch.

SAFAL: Safe Minimal Aluminium

Aluminium gives conventional fireworks their brilliance but adds to fine particles. SAFAL uses only a minimal amount, mainly in the flash powder that initiates the effect. A particulate cut of about 35 to 40% was reported at launch.

SWAS vs STAR vs SAFAL at a glance

• SWAS (Safe Water Releaser): water vapour and dust suppression; about 30–35% less particulate matter reported in 2018.
• STAR (Safe Thermite Cracker): modified, more efficient combustion; about 35–40% less particulate matter reported, with lower SO₂ and NOx.
• SAFAL (Safe Minimal Aluminium): minimal aluminium; about 35–40% less particulate matter reported.

These are the figures reported when the formulations were launched, not a guarantee for every product on sale today; product test reports and current certification are what count.

Green does not mean pollution-free

Green crackers still release fine particulates (PM2.5 and PM10), sulphur dioxide, nitrogen oxides and smoke, and their noise still frightens people and animals. Follow local restrictions and timings, buy only from authorised sellers, keep children away from ignition, avoid hospitals and vulnerable neighbours, and consider lamps, community lighting and quieter celebrations.

How to identify an authorised green cracker

1. The pack declares its green-cracker category.
2. It carries the CSIR-NEERI green logo and a QR code you can scan to verify it.
3. Manufacturer, product and PESO licence details are printed.
4. The product is allowed under the rules where you live this year.

A shopkeeper's word, or "eco" printed on a box, is not proof. Rules differ by state and city; for example, Tamil Nadu's 2026 rules.

Why it matters for Hindu families

Sivakasi is an Indian industrial story of entrepreneurs, workers and distributors, and the green-cracker programme adds science to a festive tradition. The values Hindu families bring to it are ahimsa, compassion and consideration for others. The light of Deepavali, the light of the stories behind Diwali, can be celebrated while caring for people, animals and the environment, or with no crackers at all (ideas for a cracker-free Diwali).

Frequently asked questions

Why is Sivakasi famous for firecrackers?

Sivakasi in Tamil Nadu's Virudhunagar district grew from a safety-match town into India's best-known fireworks centre, helped by its dry climate, manufacturing experience, skilled workforce and nationwide distribution.

What is Standard Fireworks?

Standard Fireworks (P) Ltd is an established Sivakasi fireworks maker. By the company's own account its history began in 1942 with a safety-match unit founded by Shri Yennarkay R. Rajaratnam.

What are the full forms of SWAS, STAR and SAFAL?

SWAS is Safe Water Releaser, STAR is Safe Thermite Cracker and SAFAL is Safe Minimal Aluminium: three green-cracker formulations developed under CSIR, with CSIR-NEERI, and announced in October 2018.

How much do SWAS, STAR and SAFAL reduce pollution?

At the October 2018 launch, particulate reductions of about 30 to 35% were reported for SWAS and about 35 to 40% for STAR and SAFAL, compared with conventional crackers. These are development figures, not guarantees for every product sold today.

Are all Sivakasi crackers green crackers?

No. Sivakasi makes many kinds of fireworks. Check each product's green logo, QR code and licence details, and do not assume any brand's whole range is SWAS, STAR or SAFAL.

Are green crackers pollution-free?

No. They cut certain emissions but still release smoke, particulates, gases and noise.
