Tips for fly ash bricks manufacturing

The fly ash brick manufacturing sector is a rapidly expanding and profitable business opportunity in India, driven by environmental awareness and regional restrictions on traditional red clay brick production.

Key considerations for starting a fly ash brick business

Land requirements

Approximately half an acre is the minimum, though one full acre is recommended for adequate stock and curing space.

Factory location

Position facilities within 100 km of a thermal power plant to secure a reliable fly ash quota from the electricity board.

Water availability

The fly ash bricks manufacturing process requires a lot of water, so proximity to freshwater sources is essential for operations.

Environmental concerns

Fly ash handling demands careful attention, as micro dust particles are harmful to the people around the facility. Sites should avoid residential areas, and some operators use silos for storage.

Project cost

Approximately Rs. 30,00,000 covers plant, machinery and working capital for operations producing 12,000 bricks per shift, excluding diesel generators.

Cement industry competition

Large cement manufacturers operate giant silos at thermal power plants, taking up most of the available fly ash supply, which makes procurement harder for smaller operators.

Labour availability

Recruiting suitable workers can be difficult due to dusty working conditions. Offering competitive wages and incentives helps attract personnel.

Profitability

Expected margins are approximately Re. 1 per brick, varying by location and dependent on raw material availability, labour costs and power supply reliability.

Fly ash sourcing

Success depends on securing consistent fly ash availability from thermal power plants rather than relying on unreliable sources.

Equipment selection

Rotary hydraulic machines are recommended for new entrepreneurs as a cost effective option that requires regular professional maintenance.
