How to Start Fly Ash Bricks Making Business in Pakistan – Waste to Money Industrial Guide
Pakistan me construction industry continuously grow kar rahi hai, lekin us growth ke sath ek serious issue bhi hai: industrial waste ka disposal. Power plants, textile mills, boilers aur cement industry se nikalne wala fly ash aur biomass ash aksar waste ban kar dump hota hai.
Lekin jo log industry samajh lete hain, un ke liye ye waste nahi hota — ye “raw material” hota hai paisa banane ka.
Is business ko kehte hain: Fly Ash Bricks / Eco Bricks Manufacturing Business.
Aaj hum isko practical industrial angle se samjhenge, Pakistan market ke hisaab se, aur real machines (Silver Steel Mills systems) ke reference ke sath.
Pakistan Me Fly Ash Aur Biomass Ash Kahan Se Aata Hai?
Pakistan me fly ash aur biomass ash mainly in industries se aata hai:
1. Textile Industry Boilers
- Nishat Mills
- Sapphire Textile
- Gul Ahmed
- Interloop
- Master Group of Industries
In factories me boilers continuously steam generate karte hain. Fuel burning ke baad:
- biomass ash
- coal ash
- boiler dust
waste form me nikalta hai.
2. Power Plants & Cement Industry
- coal based plants
- cement kilns
Yahan se fly ash large quantity me milta hai.
3. Sugar Mills & Industrial Boilers
Seasonal production ke sath ash waste generate hota rehta hai.
Fly Ash Bricks Business Kya Hai?
Fly ash bricks basically cement, fly ash, sand aur crusher dust se banne wali eco-friendly bricks hoti hain.
Traditional kiln bricks ke comparison me:
- strength zyada hoti hai
- water absorption kam hoti hai
- shape uniform hoti hai
- environment friendly hoti hain
Pakistan me ab:
- housing societies
- government projects
- commercial buildings
fly ash bricks ko prefer kar rahe hain.
Waste to Money Concept (Real Industrial Logic)
Agar aap simple language me samjhein:
- Boiler waste = free raw material
- Cement + machine = production system
- Brick selling = cash flow
Ek textile mill jahan pe ash dump hota hai, wahi ash agar collect karke factory me use ho jaye to cost drastically reduce ho jati hai.
Isi liye ye business “waste to wealth” model ban chuka hai.

Fly Ash Bricks Business Kaise Start Karein Pakistan Mein – Waste Se Money Tak
By Silver Steel Mills – Fly Ash Brick Machine Manufacturer Since 2005
Yeh baat hai 2018 ki. Main Lahore mein ek textile mill ke boiler room mein khara tha. Wahan se har roz tonnes ka bio mass ash (bagasse ash) nikalta tha. Mill wale woh ash kachra samajh kar phaink rahe the. Paise de kar truck bharte the ash ko dump karne ke liye.
Main ne unhe kaha, “Yeh ash mere de do. Main tumhe paise dunga.”
Unhe yakeen nahi aaya. Aaj wohi mill mujhe ash free mein deti hai. Aur main us ash se lakhon bricks bana kar textile industry ke hi contractors ko bechta hun.
Yeh article unhi logon ke liye hai jo “waste” mein “wealth” dekh sakte hain.
Pakistan mein har roz textile mills, sugar mills, aur power plants se hundreds of tonnes fly ash aur bio mass ash nikalta hai. Nishat, Sapphire, Gul Ahmed, Master Textiles, Kohinoor – yeh sab boiler ash ko kachra samajhte hain.
Agar aap yeh ash le kar fly ash bricks bana sakte ho, toh aapka raw material practically free hai. Sirf transport ka kharcha.
Aao samajhte hain kaise.
1. Fly Ash Kya Hai? Bio Mass Ash Kya Hai? Waste Kyon Hai?
Fly Ash: Coal jalane se banti hai. Power plants mein hoti hai. Pakistan mein coal plants limited hain, lekin jo hain unse ash milti hai.
Bio Mass Ash (Agri Waste Ash): Textile mills mein boiler jalane se banti hai. Bagasse (ganne ka chilka), rice husk, wood chips, aur textile waste se banti hai.
Pakistan mein ash waste kis industry se milti hai:
| Industry | Ash Type | Annual Ash (approx) | Current Disposal |
|---|---|---|---|
| Textile mills (Nishat, Sapphire, Gul Ahmed, Master, Kohinoor, etc.) | Bio mass ash | 10,000-50,000 tons per mill | Landfill (paying to dump) |
| Sugar mills | Bagasse ash | 5,000-20,000 tons per mill | Landfill or agricultural use |
| Coal power plants (Sahiwal, Hub, Port Qasim) | Fly ash (Class F) | 100,000+ tons | Some sold, most dumped |
| Rice mills | Rice husk ash | 1,000-5,000 tons per mill | Mostly dumped |
Yeh ash waste nahi hai. Yeh gold hai.
Agar aap is ash ko collect karte ho, fly ash bricks bana te ho, aur construction industry ko bechte ho – toh aap:
- Raw material almost free le rahe ho (sirf transport cost)
- Environment bacha rahe ho (landfill se ash hat rahi hai)
- Profit kama rahe ho
Real example: Lahore ke ek textile mill se main har roz 20 tons ash nikalta hun. Mill wale mujhe ash free dete hain. Sirf loading ka kharcha hai. 20 tons ash se 6,000-7,000 bricks banti hain. Raw material cost almost zero.
2. Fly Ash Brick Business Model – Waste Se Money
Purana model (clay bricks):
- Mitti = paid (plus royalty to government)
- Bhatha = banned in many areas (environmental issues)
- Coal/Diesel = expensive
- Labor = more (kiln needs many workers)
Naya model (fly ash bricks):
- Ash = almost free (mill se le kar aao)
- Cement = paid (thoda lagta hai – ratio 1:6 ya 1:8)
- Sand = paid (thoda)
- Machine = ek baar ka investment
- Labor = kam (machine automatic hai)
Raw material cost comparison (per brick):
| Material | Clay Brick | Fly Ash Brick (with free ash) |
|---|---|---|
| Clay/Ash | PKR 2-3 (clay + royalty) | PKR 0.50 (sirf transport) |
| Cement | 0 (nahi lagta) | PKR 10-15 |
| Sand | 0 (nahi lagta) | PKR 3-5 |
| Water | PKR 0.50 | PKR 0.50 |
| Coal/Diesel | PKR 5-8 | 0 (no burning) |
| Total raw material | PKR 8-12 | PKR 14-21 |
Fly ash bricks ka raw material cost zyada lagta hai? Gaur karo – clay bricks mein coal/diesel ka kharcha PKR 5-8 hai jo fly ash bricks mein nahi hai. Aur clay bricks ki strength kam hoti hai (500-800 psi). Fly ash bricks ki strength zyada hoti hai (2,000-3,500 psi).
Real cost comparison including all factors:
| Factor | Clay Brick (per 1,000 bricks) | Fly Ash Brick (per 1,000 bricks) |
|---|---|---|
| Raw material | 8,000-12,000 | 14,000-21,000 |
| Labor (kiln vs machine) | 5,000-8,000 | 2,000-3,000 |
| Fuel (coal/diesel vs electricity) | 5,000-8,000 | 3,000-5,000 (electricity) |
| Environmental compliance (zigzag, etc.) | 2,000-5,000 | 0 (no smoke) |
| Total cost | 20,000-33,000 | 19,000-29,000 |
| Selling price | 25,000-35,000 | 25,000-35,000 |
| Profit per 1,000 bricks | 2,000-5,000 | 4,000-8,000 |
Fly ash bricks double profit de sakte hain agar ash free mile.
3. Ash Kaise Hasil Karein – Nishat, Sapphire, Master, Kohinoor, Gul Ahmed Se
Step 1: Textile mills mein jaao
Pakistan ke bade textile mills:
- Nishat (Lahore, Faisalabad) – boilers hain, ash nikalta hai
- Sapphire (Lahore, Karachi) – bio mass boilers
- Gul Ahmed (Karachi, Lahore) – textile + power
- Master Textiles (Lahore) – boilers
- Kohinoor Textiles (Lahore, Raiwind) – boilers
- Indus Dyeing (Faisalabad) – boilers
- Chenab Textiles (Faisalabad) – boilers
Step 2: Boiler manager se milo
Unse kaho: “Main aap ki ash le kar jaunga. Aap ko paise dene ki zaroorat nahi. Bas mujhe loading ka time batao.”
Kyun koi mill ash free de ga?
- Abhi woh ash dump karne ke liye paise de rahe hain (truck, labor, landfill fee)
- Agar aap le kar jaao, toh unka kharcha bachta hai
- Some mills ash bechte hain (PKR 500-1,000 per ton). Negotiate karo.
Step 3: Ash ki quality check karo
| Ash Type | Quality for Bricks | Notes |
|---|---|---|
| Bio mass ash (bagasse, rice husk) | Good | Thoda light hai, lekin kaam karta hai |
| Coal fly ash (Class F) | Excellent | Strongest bricks |
| Wood ash | Average | Thoda weak hai |
| Textile waste ash | Good | Depends on what was burned |
Step 4: Transport arrangement
Ash utha kar apni factory lao. Ek tipper truck 10-15 tons ash le jata hai. Distance ke hisab se PKR 2,000-5,000 per trip.
4. Machine Specifications – Fly Ash Brick Machine
Fly ash bricks ke liye special machine chahiye. Ordinary block machine se nahi banegi.
Requirement for fly ash bricks:
| Requirement | Why |
|---|---|
| Higher pressure (hydraulic) | Ash mix ko compress karne ke liye zyada pressure chahiye |
| Vibration | Ash mix thoda dry hota hai – vibration se compact hota hai |
| Mould design | Fly ash bricks ka size different hota hai (9″x4″x3″ standard) |
| Curing system | Fly ash bricks ko steam curing (autoclave) ya 21 days water curing chahiye |
Silver Steel Mills – SSM Fly Ash Series:
| Model | Pressure (psi) | Daily Bricks | Price (PKR) | Best For |
|---|---|---|---|---|
| SSM-15 Fly Ash | 3,000+ | 3,500-4,500 | 45,00,000 | Startup |
| SSM-28 Fly Ash | 4,000+ | 8,000-10,000 | 1,10,00,000 | Medium |
| SSM-35 Fly Ash (with autoclave) | 5,000+ | 15,000-20,000 | 1,80,00,000+ | Industrial |
What makes SSM fly ash machine different:
| Feature | Standard Block Machine | SSM Fly Ash Machine |
|---|---|---|
| Hydraulic pressure | 2,000-3,000 psi | 4,000-5,000 psi |
| Vibration frequency | 3,000-4,000 RPM | 4,500-5,000 RPM |
| Mixer type | Normal | Heavy duty (ash mix is abrasive) |
| Mould steel | Normal | Wear-resistant (ash wears moulds faster) |
| Curing requirement | 7 days water | 21 days water OR steam autoclave |
Autoclave (steam curing) kya hai?
Fly ash bricks ki actual strength steam curing se aati hai. Agar aap sirf water curing karo ge, toh bricks 2,000-2,500 psi ki hongi. Steam curing (autoclave) se 3,500-4,500 psi ki strength aati hai.
Autoclave cost: PKR 25-40 lakhs for small scale. Agar aap Nishat ya Sapphire jesi mill ke paas plant lagao ge, toh woh boiler se steam de sakte hain (negotiate karo).
5. Production Capacity – Kitni Bricks Banegi Roz
SSM-15 Fly Ash (8-hour shift):
| Brick Size | Pieces Per Pallet | Pallets Per Hour | Daily Bricks |
|---|---|---|---|
| 9″ x 4″ x 3″ (standard) | 15 | 30-35 | 3,600-4,200 |
| 8″ x 4″ x 3″ | 18 | 30-35 | 4,300-5,000 |
SSM-35 Fly Ash with autoclave (8-hour shift + curing time):
| Brick Size | Daily Bricks | Steam Curing Time | Total Production Cycle |
|---|---|---|---|
| 9″ x 4″ x 3″ | 15,000-18,000 | 12 hours | Ready next day |
Ash consumption per 1,000 bricks:
| Mix Ratio | Ash (kg) | Cement (kg) | Sand (kg) |
|---|---|---|---|
| 1:6 (1 cement : 6 ash) | 180 | 30 | 30 |
| 1:8 (1 cement : 8 ash) | 200 | 25 | 25 |
| 1:10 (1 cement : 10 ash – weaker) | 220 | 20 | 20 |
Example: Agar aap 1:8 ratio use karo ge, toh 1,000 bricks ke liye 200 kg cement chahiye (4 bags – PKR 5,000 approx) aur 200 kg ash (almost free). Baqi 25 kg sand.
6. Electricity Requirements
SSM-15 Fly Ash:
| Component | HP |
|---|---|
| Hydraulic pump | 25 (zyada pressure ke liye) |
| Vibration motors | 10+10 |
| Mixer | 20 |
| Conveyor | 3 |
| Total | 68 HP |
Daily consumption: 350-400 units. Monthly cost: PKR 3.5 – 4.0 lakhs.

| Cement storage | 500 |
| Curing yard (water curing – 21 days) | 5,000-6,000 |
| Finished goods | 2,000-3,000 |
SSM-35 with autoclave: 6-8 Kanal (30,000-40,000 sq ft)
| Area | Size (sq ft) |
|---|---|
| Plant + batching | 2,000-2,500 |
| Ash storage (silo or covered) | 2,000-3,000 |
| Autoclave area | 1,500-2,000 |
| Curing yard | 10,000-15,000 |
| Finished goods | 5,000-6,000 |
Ash storage important: Ash mein moisture absorb hoti hai. Covered storage rakho. Khuli jagah mein ash wet ho jaye gi toh bricks weak banegi.
9. Manufacturing Process – Fly Ash Bricks
Step 1: Ash preparation
Ash ko seive karo (extra carbon ya bade particles hatao). Agar ash bohot dry hai toh thoda pani daalo (6-8% moisture).
Step 2: Batching
Ash : Cement : Sand = 6:1:1 ya 8:1:1. Measuring box use karo ya digital batching.
Step 3: Mixing
Dry mix karo pehle (ash + cement + sand) – 2 minutes. Phir pani daalo – 1 minute aur mix karo.
Mix consistency: Mix itna dry ho ke jab haath mein dabao toh shape ban jaye aur pani na tapke. Fly ash bricks ka mix clay bricks se dry hota hai.
Step 4: Molding and pressing
Mix mold mein dalo. Vibration (high frequency) chaloo karo. Phir hydraulic pressure (4,000-5,000 psi) apply karo. Yeh pressure fly ash bricks ko strong banata hai.
Step 5: Stripping
Mold uthay. Brick pallet par rehti hai. Fly ash bricks turant utha sakte ho (normal blocks se zyada strong hoti hai fresh stage par).
Step 6: Curing – do tareeqay:
| Method | Process | Strength Achieved | Time |
|---|---|---|---|
| Water curing | 21 days, spray water 4-6 times/day | 2,000-2,500 psi | 21 days |
| Steam curing (autoclave) | 8-12 hours at 150-200°C | 3,500-4,500 psi | Next day ready |
Step 7: Delivery
Bricks check karo – edges sharp hon, cracks na hon. Phir delivery.

11. Maintenance Guidance
Daily:
| Item | Action |
|---|---|
| Mixer | Clean – ash mix sticks to blades |
| Mold | Clean with wire brush |
| Hydraulic oil | Check level |
Weekly:
| Item | Action |
|---|---|
| Bearings | Grease (ash dust wears bearings faster) |
| Conveyor belt | Clean ash residue |
| Ash storage | Check moisture – wet ash ruins mix |
Monthly:
| Item | Action |
|---|---|
| Hydraulic oil | Change every 1,000 hours |
| Mould | Check wear – ash is abrasive, mould wears 30% faster than normal |
Ash-specific issue: Ash dust bahut fine hoti hai. Yeh machine ke bearings, motors, aur electrical panel mein ghus jaati hai. Machine ko daily clean karo. Sealed bearings use karo. Electrical panel ko sealed room mein rakho.
12. Comparison Table: Fly Ash Bricks vs Clay Bricks vs Concrete Blocks
| Feature | Clay Bricks | Concrete Blocks | Fly Ash Bricks |
|---|---|---|---|
| Raw material cost | Medium (mitti + coal) | Medium (cement + crush) | Low to zero (free ash) |
| Strength (psi) | 500-800 | 2,000-3,000 | 2,500-4,500 |
| Weight (per brick) | Heavy (3-4 kg) | Light (2-3 kg) | Light (2-3 kg) |
| Water absorption | High (15-20%) | Medium (10-15%) | Low (5-10%) |
| Heat insulation | Medium | Good | Excellent |
| Environmental impact | High (smoke, soil erosion) | Medium (cement CO2) | Low (waste utilization) |
| Govt approval | Restricted (kilns closing) | Approved | Encouraged |
| Selling price (per brick) | PKR 8-12 | PKR 12-18 | PKR 20-30 (higher due to strength) |
Why fly ash bricks sell for higher price: Contractors zyada price dete hain kyunki fly ash bricks light weight hain (transport cost kam), heat insulation achha hai (upstairs rooms thande rehte hain), aur strength zyada hai.
13. FAQs for Fly Ash Brick Business
Q1: Kya fly ash bricks ghar banane ke liye safe hain?
Yes. Fly ash bricks NESPAK aur PWD approved hain. Radiation ka koi risk nahi – Pakistani fly ash mein radioactivity negligible hai.
Q2: Ash free mein milti hai ya paise de kar?
Depends on mill. Kuch mill free mein dete hain (unka kharcha bachta hai). Kuch PKR 500-1,000 per ton lete hain. Negotiate karo. Agar mill paise mange, toh doosri mill try karo.
Q3: Kis mill se ash milegi?
Target:
- Textile mills (Nishat, Sapphire, Gul Ahmed, Master, Kohinoor, Indus, Chenab)
- Sugar mills (Kamalia, Ramzan, etc. – bagasse ash)
- Power plants (Sahiwal, Hub, Port Qasim – fly ash)
Q4: Steam curing autoclave necessary hai?
Water curing se bhi kaam chal jata hai (2,000-2,500 psi strength). Lekin agar aap high-strength bricks (3,500+ psi) banana chahte ho for commercial projects, toh autoclave chahiye.
Q5: Fly ash bricks ki selling price kya hai Pakistan mein?
| City | Price Range (per brick) |
|---|---|
| Lahore | PKR 22-30 |
| Rawalpindi/Islamabad | PKR 25-35 |
| Karachi | PKR 25-35 |
| Faisalabad | PKR 20-28 |
Q6: Kya main textile mill ke andar hi plant laga sakta hun?
Yes – best idea. Mill ki ash direct machine mein jaye gi. Mill boiler se steam autoclave ke liye mil jaye gi. Aur mill ke contractors bricks khareedenge. Nishat ke paas multiple plants hain aise.
Q7: Kya fly ash bricks ke liye special mould chahiye?
Yes. Size standard hota hai 9″x4″x3″ ya 8″x4″x3″. Hum SSM fly ash machine ke saath mould provide karte hain.
Q8: Nishat, Sapphire, Master boilers se kitni ash milti hai har roz?
Bade textile mill mein multiple boilers hotay hain. Har roz 20-50 tons ash nikal sakta hai. 20 tons ash se 6,000-7,000 bricks banti hain.
14. Buyer Guidance – Fly Ash Brick Plant Kaise Lagayein
Step 1: Mill se contract karo
Pehle ash ka source confirm karo. Mill management se milo. Agreement karo ke woh ash tumhe dein gay (free ya paid). Signed agreement le kar aao.
Step 2: Ash ki testing karo
Ash sample lab bhejo. Check karo:
- Unburned carbon content (kam ho toh better)
- Fineness (fine ash better bricks banati hai)
- Moisture (dry ash better)
Step 3: Machine choose karo
| Agar ash free ya cheap mil rahi hai… | Buy this |
|---|---|
| 5-10 tons per day ash | SSM-15 Fly Ash |
| 15-25 tons per day ash | SSM-28 Fly Ash |
| 30+ tons per day ash + boiler access | SSM-35 with autoclave |
Step 4: Mill ke paas ya qareeb land le lo
Ash transport cost bachta hai. Curing ke liye boiler steam bhi use kar sakte ho.
Step 5: Cement aur sand ka arrangement karo
Fly ash bricks mein cement ka ratio zyada hota hai (1:6 ya 1:8). Cement bulk mein lao (500+ bags) – sasta padta hai.
Step 6: Curing facility banao
Water curing ke liye 21 days ka space chahiye. Steam curing ke liye autoclave chahiye.
Step 7: Buy machine from Silver Steel Mills
Aao humare factory. Fly ash machine dekh lo. Ash lekar aao – hum run karein ge machine. Bricks ki quality check karo. Phir decide karo.
15. Market Demand for Fly Ash Bricks in Pakistan
Demand drivers:
| Driver | Explanation |
|---|---|
| Clay brick kilns band ho rahe hain | Environmental cases, zigzag compliance issues |
| Government promotion | Fly ash bricks ko green building material consider kiya jata hai |
| Contractor preference | Light weight = kam transport cost. Heat insulation = AC kam chalay |
| Housing schemes | DHA, Bahria, and others approved fly ash bricks |
Market size: 10-15% of brick market already fly ash. Expected to grow to 30-40% in 5 years.
Price trend: Fly ash brick prices steady increasing (PKR 20 in 2020, PKR 28 in 2026). Clay bricks prices volatile due to kiln closures.
16. Future Industry Trends
Trend 1: More textile mills will shift to bio mass boilers
Government policy encourages bio mass (bagasse, rice husk, wood chips) instead of furnace oil. More boilers = more ash.
Trend 2: Coal power plants will supply fly ash to brick plants
Currently, Sahiwal coal plant ash is underutilized. This will change.
Trend 3: Autoclave will become standard for fly ash bricks
Water curing se 21 days lagte hain. Autoclave se next day ready. Large scale producers autoclave adopt kar rahe hain.
Trend 4: Government will ban or restrict clay bricks eventually
It will take 5-10 years, but direction is clear. Fly ash bricks are the future.
