Affordable Clean Energy for Homes & Small Farms
Our small biogas plants are designed for individual households, small dairy farms, hostels, and rural communities. With capacities ranging from 2 m³ to 20 m³ per day, these compact systems convert daily kitchen waste and cattle dung into cooking gas, eliminating LPG cylinder dependency while producing nutrient-rich organic fertilizer.
Perfect Biogas has installed over 1000 small-scale biogas plants across rural and semi-urban India since 1998, bringing clean cooking fuel to families and reducing deforestation caused by firewood collection.
Small biogas systems offer energy independence at minimal investment. They're perfect for families keeping 2-10 cattle or generating 20-50 kg of kitchen waste daily.
| Plant Size | Daily Input | Gas Production | Cooking Hours | Family Size |
|---|---|---|---|---|
| 2 m³ | 10-15 Kg | 2 m³/day | 2-3 hours | 3-4 members |
| 5 m³ | 20-30 Kg | 5 m³/day | 4-5 hours | 5-7 members |
| 10 m³ | 40-50 Kg | 10 m³/day | 8-10 hours | Joint family/hostel |
| 15 m³ | 60-80 Kg | 15 m³/day | 12-15 hours | Small dairy/hostel |
| 20 m³ | 80-100 Kg | 20 m³/day | 15-18 hours | 10-15 cattle farm |
Families keeping 2-10 cows or buffalo produce 20-100 Kg dung daily. A small biogas plant converts this waste into cooking gas, eliminating firewood collection and LPG costs while improving kitchen hygiene.
Apartments and bungalows generating 5-15 Kg daily kitchen waste can install compact 2-5 m³ plants. Perfect for eco-conscious families wanting to reduce waste sent to landfills.
Dairies with 5-15 animals benefit from 10-20 m³ plants. Generate cooking gas for dairy workers' quarters plus premium organic fertilizer for fodder cultivation.
Residential institutions with 50-100 students generate substantial food waste. A 15-20 m³ plant provides cooking gas for mess kitchens while teaching students about sustainable energy.
Religious institutions serving daily meals can convert kitchen waste into cooking fuel, demonstrating environmental stewardship while reducing operating costs.
Perfect Biogas small plants feature two proven designs:
Small biogas plants accept various organic materials:
Do NOT feed: Plastics, metal, glass, bones, excessive oil/grease
Time Required: 10-15 minutes daily (feeding & basic checks)
Example: 5 m³ Family Biogas Plant
Small biogas plants qualify for:
Perfect Biogas assists with subsidy applications and documentation.
Q: How much space is needed?
A: 2m³ plant needs 10 sq.m, 5m³ needs 20 sq.m, 10m³ needs 35 sq.m
Q: Does it work in winter?
A: Yes, but gas production reduces 20-30% below 15°C. Insulation or heating recommended for cold regions.
Q: What if I travel for 10-15 days?
A: No feeding needed. Plant remains dormant, resumes when feeding restarts.
Q: Can I use it for lighting?
A: Yes, with biogas lamps or small generators (5m³+ plants)
