“Piloto ”Manure-to-Fertiliser" - 20 compostores de membrana capacitam pequenas granjas de suínos

Case Study | HEZHOU, GUANGXI

1 . Project Background

Guangxi’s Hezhou City is a major pork-producing region. Hundreds of small and mid-size farms generate large volumes of pig manure, often stored in open piles that trigger odour complaints and water-pollution risks. In 2024 the Hezhou Agriculture & Rural Affairs Bureau launched a “Manure → Fertiliser” initiative, aiming to turn waste into profit while meeting tightened environmental regulations.

2 . Jiesonglin Solution

Under a government–enterprise partnership, 20 pilot farms each received a 200 m³ e-PTFE membrane composter supplied by Tecnologia Jiesonglin:

• On-site composting pad reserved at every farm
• Pig manure blended with rice husk / sawdust, loaded into compost cell
• Gas-permeable nanomembrane cover + smart aeration & temperature control
• Fully sealed process—no odour, seepage or fly nuisance

The “farm-level compost point” model keeps treatment local and scalable.
