30 day composting vs. 3-month composting: the dual advantages of "speed and ecology" of GGT aerobic fermentation equipment

On August 1, 2025, the "Technical Specification for Returning Livestock and Poultry Manure to the Field" (GB/T 25246-2025) was officially implemented, marking an industry revolution in the treatment of livestock and poultry manure. The new standard clearly stipulates that strict hygiene indicators such as a mortality rate of roundworm eggs ≥ 95% and a fecal coliform value ≤ 10 ⁻ ² must be met before returning livestock and poultry manure to the field. For breeding farms and agricultural enterprises that are still using traditional composting methods, this is like a warning bell - those who rely on natural fermentation for a long 3-month wait not only mean low efficiency, but also may face compliance risks due to excessive bacteria.

The GGT aerobic fermentation equipment provides a new solution for the industry with a "speed" of 30 day maturation cycle and far exceeding the standard "ecological" indicators.

Time Revolution: Crossing from Season to Month
The traditional method of composting is like a gamble of 'watching the sky and eating'. Due to temperature fluctuations and insufficient oxygen supply in the natural environment, a qualified composting process often takes no less than 90 days to complete. The emergence of GGT aerobic fermentation equipment has completely rewritten this situation. The core of it is to cover a layer of specialized molecular film on the surface of the pile to form a closed environment, reduce the emission of pollutants, and supply oxygen through aeration pipes at the bottom of the pile to promote rapid decomposition of materials. The entire fermentation process takes 30-60 days.
Ecological efficiency comparison between aerobic fermentation and traditional heap fermentation with hard core
1. Bacterial killing: the "purification power" of high temperature
Traditional composting is difficult to sustain at standard temperatures (usually fluctuating between 30-50 ℃), resulting in incomplete killing of bacteria. The Guogangtong equipment adopts a constant temperature control system of 60-70 ℃, combined with a high-temperature section design that lasts for more than 3 days, to achieve a pathogen removal rate of 99.9%, fully meeting and exceeding the hygiene requirements of the new national standard. This treatment not only avoids the risk of disease and pest transmission after returning manure to the field, but also reduces the environmental hazards of antibiotic substances penetrating through the soil.

2. Nutrient retention: the "preservation technique" of time
The nitrogen loss rate of aerobic fermentation is only 10-20%, much lower than the 30-50% of traditional composting. The membrane fermentation technology used in GGT equipment achieves selective emission of water vapor and carbon dioxide through a specially designed polymer membrane, while intercepting volatile nutrients such as ammonia.
Compliance Era: Technology Selection under the New National Standard
The implementation of GB/T 25246-2025 marks the entry of the "mandatory standard era" for livestock and poultry manure treatment. Compared to the 2010 version, the new standard has three key changes worth noting:
Upgrading of terminology system: Clearly distinguish between "livestock and poultry manure" and "livestock and poultry manure fertilizer", emphasizing that only products that have undergone harmless treatment can be returned to the field.
Tightening hygiene indicators: Merge the requirements for dispersed compost and biogas fertilizers into a unified hygiene standard for livestock and poultry manure.
Strengthening of standard responsibility traceability: adding a new chapter on "Recording and Effect Monitoring", requiring full recording of processing parameters throughout the process.
The intelligent control system of GGT equipment precisely responds to these changes - the PLC system automatically records key data such as temperature, oxygen concentration, processing time, etc., forming a traceable electronic ledger; The molecular membrane coverage design controls the ammonia concentration below 5ppm in emissions, which complies with the "Odor Pollutant Emission Standards" while avoiding compliance risks.
Not Just Fast: Deep Reconstruction of Ecological Value
The significance of aerobic fermentation goes far beyond efficiency improvement. The GGT device achieves triple ecological value through a composite system of "biotransformation+environmental regulation":
Carbon Reduction effect: High temperature aerobic environment allows microorganisms to consume more than 80% of greenhouse gases, reducing ammonia emissions by 57% and hydrogen sulfide emissions by 89% compared to traditional composting.
Pollution zero emissions: The sealed design of the membrane oxygen chamber effectively eliminates the problems of odor diffusion and non-point source pollution in traditional composting, eliminates mosquito and fly breeding and sewage leakage, and completely solves the pain points of secondary pollution in traditional composting.
Soil improvement: Fermentation products rich in humus (organic matter ≥ 45%) can significantly enhance soil water and fertilizer retention capacity, forming a virtuous cycle of agricultural production.

Agriculture and Rural Affairs, aerobic fermentation equipment is transforming the 'environmental burden' of the breeding industry into the 'ecological capital' of the planting industry, which is exactly the development direction that GB/T 25246-2025 wants to guide. ”
Choice is the future
When 30 days of efficient processing can meet the requirements of the new national standard and create higher economic value, the withdrawal of traditional composting methods will become inevitable. The dual advantages of speed and ecology in the aerobic fermentation equipment of Guogangtong are not only a technological victory, but also a practice of the concept of green agricultural development.
For aquaculture enterprises, what needs to be considered now is no longer "whether to change or not", but "how to upgrade as soon as possible" - after all, driven by the dual drive of environmental compliance and efficiency improvement, every day of hesitation may mean more cost losses and missed opportunities.
