Case Study | XINING, QINGHAI

1 . Project Background
A large dairy farm in Xining keeps >3 000 Holstein cows, producing nearly 40 t of manure every day. Traditional windrow composting for fertiliser was slow and labour-intensive, while the farm still spent heavily on sawdust bedding each year. In early 2024 management chose a circular “manure-to-bedding” model to cut costs and improve sustainability.
2 . Jiesonglin Solution

After extensive evaluation the farm installed six 200 m³ e-PTFE membrane composters from Jiesonglin Technology. The closed aerobic process works as follows:
- Blend fresh dung with bulking agents
- Load mixture into sealed compost cells
- Cover with gas-permeable nanomembrane
- Auto-control temperature & humidity for high-temperature kill of pathogens and eggs
- Harvest dry, fluffy, odour-free bedding
3 . Proven Results

| KPI | Value |
|---|---|
| Composting cycle | ≤ 25 days |
| Annual bedding output | ≈ 2 000 t |
| Bedding cost reduction | > 30 % (≈ CNY 200 000 saved/yr) |
| Animal health impact | Lower mastitis rate, higher milk yield |
The recycled bedding is highly absorbent and comfortable, enhancing udder hygiene and cow welfare.
4 . Customer Testimonial
“These composters solved our manure headache and slashed bedding expenses.
The cows like the soft, dry material, and we’re thrilled to turn waste into real value.”
— Farm Manager, Xining Dairy
5 . Demonstration Value
This project sets a “Xining model” for high-altitude dairy regions, showcasing efficient manure utilisation, cost savings and greener livestock production on the Qinghai-Tibet Plateau.
