Project Background A large duck farm in Tong Ling, Anhui, finishes >500 000 ducks per year, producing ≈30 t of fresh manure daily. Open-air stockpiles created odour, flies and regulatory fines. Management decided to “treat the source” with a closed, high-efficiency composting solution. 2. Jiesonglin Solution In 2022 we installed six 400 m³ e-PTFE membrane composting units. The system follows an “collect → mix → on-site ferment → on-site reuse” workflow: 3. Measurable Results KPI Before After Compost cycle 60 days 25 days Odour / flies Complaints & fines >99 % reduction Fertiliser output 0 4 000 t y⁻¹ organic fertiliser Finished humus is applied to the farm’s orchards and vegetables; surplus is sold locally—turning a cost centre into a profit stream. 4. Customer Testimonial “Duck manure used to be a headache—now it’s black gold.The membrane composter passed our environmental audit with ease and creates an extra fertiliser revenue stream while saving land, labour and money.”— Farm Manager, Tong Ling
