• 1400 bricks are made from 200 cubic foot soil/clay

• In one day 2 labors can make 1000 green bricks

• One batch is of 3000 bricks

• In one day 4 firing men are required for firing

• Fresh bricks are sold at Rs 4200 – Rs 5700 per 1000 bricks depending upon the quality

Financials(3/3)Financials(3/3)

• Cost per 1000 bricks• Rs. 715 for soil (Rs1000/1400)*1000• Rs. 450 for 2 labors for making green bricks.• Rs. 1000 for coal (Rs3000/ 3000)*1000• Rs. 300 for firing crew ((Rs225*4)/3000)*1000• Rs. 200 for shifting, assorting and arranging bricks.

– Total cost for 1000 bricks is Rs. 2665• Gross profit

• Average Sales (Rs. 5100) – direct cost (Rs. 2665) = Rs. 2435 per 1000 bricks

Types of kilnsTypes of kilns

• Clamp Kiln – ANCIENT TECHNOLOGY - 4,000 B.C.The Most Commonly Used Kiln In The Developing World. These Kilns Have A Devastating Impact Both On The Environment And Workers.

• Tunnel Kiln - Invented Germany 1877Most Common In Developed Countries, Since Their Invention Tunnel Kilns Have Now Become Highly Automated.

• Bulls Trench – Invented England 1876Commonly Used In India. It Has No Roof And Can Only Be Used Outside The Monsoon Season.

• Vertical Shaft Kiln – Invented China 1958Reasonably Fuel Efficient However The Kiln Is Limited Due To A Low Throughput.

Bull’s Trench KilnBull’s Trench Kiln

• More fuel efficiency compared to periodic kilns

• Low initial investment

• High capacity

• Production rigid to market fluctuations

• Experienced firing crew

• Moveable chimneys have a short working life

• Less optimum firing conditions
