Compostable vs. Biodegradable: Don’t confuse these concepts

Written by fertilizer production line on January 30th, 2026.

In everyday use, “compostable” and “biodegradable” are often used interchangeably, but they are not equivalent. Compostable is a subcategory of biodegradable, with the core differences lying in decomposition conditions, product requirements, and applicable scenarios.

Decomposition conditions and timelines differ significantly. Biodegradable substances can be decomposed by microorganisms in the natural environment, with no strict parameter requirements, and the decomposition period varies from months to years, greatly influenced by environmental factors. Compostable substances require a specific composting environment (temperature 55-65℃, humidity 55%-60%, aerobic), and require equipment such as compost turning machines to control temperature, humidity, and aeration, achieving complete decomposition within 3-6 months; in large-scale processing, organic fertilizer production lines can precisely control parameters to ensure decomposition efficiency.

Decomposition products and standards differ. Biodegradable substances only require decomposition into water, carbon dioxide, and microorganisms, with no specific residue requirements. Compostable materials must decompose into harmless humus. After processing on an organic fertilizer production line, they can be used as organic fertilizer to improve soil and must meet environmental standards for heavy metals and other pollutants, without causing secondary pollution.

The applicable scenarios differ. Biodegradable materials have a wide range and are suitable for natural degradation scenarios; compostable materials are mostly organic waste such as kitchen waste and straw, which are standardized and processed using organic fertilizer production equipment to ultimately achieve resource utilization.

A common misconception is that not all biodegradable materials are compostable. Some materials are difficult to completely decompose in a composting environment and may even pollute the byproducts. The core difference lies in whether “complete degradation + resource utilization” can be achieved under composting conditions.

Can pesticides decompose in compost? Here are a few points to consider

Written by fertilizer production line on January 28th, 2026.

Composting is an important way to utilize organic waste resources and a core part of organic fertilizer production lines. However, if raw materials carry pesticide residues, whether they can decompose in compost depends on factors such as the type of pesticide, the composting environment, and equipment control.

The composting environment is crucial for decomposition, and organic fertilizer compost turning machines can precisely control this environment. Microbial communities are active in compost. Turning machines maintain an aerobic environment and ensure a high temperature of 55-65℃ for several weeks through regular turning, aiding microbial metabolism and decomposition of some pesticides. Simultaneously, the turning machine can adjust the uniformity of the material, optimizing organic matter and pH conditions in conjunction with the production line’s process parameters, thus improving decomposition efficiency. In the absence of oxygen, not only is decomposition inhibited, but toxic intermediate products may also be produced.

The type of pesticide determines the ease of decomposition. Organophosphates and pyrethroids, which are easily degradable, can be broken down into harmless substances by microorganisms under the suitable environment controlled by a compost turner, posing a low risk of residue. Organochlorines and other persistent pesticides, however, are structurally stable, heat-resistant, and resistant to degradation, making them difficult to completely decompose and prone to long-term residue.

Furthermore, high concentrations of residue can inhibit microbial activity and reduce the decomposition rate. Pesticides with prolonged residue time form stable bound states, making them even more difficult to degrade. This also places demands on the raw material testing process in organic fertilizer production lines.

It is recommended that organic fertilizer production lines prioritize the use of residue-free raw materials. If there are concerns about the raw materials, extending the high-temperature turning time and enhancing the aerobic environment through a compost turning machine can improve the degradation effect. Raw materials containing persistent pesticide residues must be strictly prohibited from being fed into the system to prevent the spread of contamination.

Key challenges in organic fertilizer composting: How to scientifically treat rainwater and leachate?

Written by fertilizer production line on January 28th, 2026.

In organic fertilizer composting, rainwater runoff and leachate produced during material fermentation can easily cause secondary pollution and damage the composting environment if not treated properly. Rainwater can lead to excessive moisture in the compost pile, triggering anaerobic fermentation. Leachate contains high concentrations of pollutants, and direct discharge can pollute soil and water sources.

Rainwater treatment should focus on “prevention first, rapid drainage.” Composting sites should have a 1%-2% slope, equipped with drainage ditches and collection pits to prevent rainwater accumulation. For open-air composting, movable rain shelters should be built, covered with impermeable membranes during the rainy season, balancing rain protection and ventilation. Simultaneously, the composting area should be divided, and emergency drainage channels should be reserved. After rain, the compost should be turned over and the moisture dispersed using a compost turning machine.

Leachate treatment requires proper collection and harmless disposal. An impermeable membrane and collection pipes should be laid at the bottom of the composting area, flowing into a dedicated collection pool to prevent leakage and groundwater contamination. Small amounts of leachate can be reinjected into the compost pile, both to decompose pollutants with the help of microorganisms and to replenish the pile’s moisture. For larger quantities, after sedimentation and filtration pretreatment, the leachate can be treated biochemically or entrusted to professional organizations for disposal, ensuring it meets standards before discharge or reuse.

Treatment efficiency can be optimized by combining leachate with organic fertilizer composting equipment. For example, using a compost turning machine to control the pile’s porosity can reduce leachate production; adjusting the raw material ratio in advance during the rainy season, increasing the proportion of dry materials, can enhance water absorption capacity.

In summary, rainwater treatment focuses on “prevention and drainage,” while leachate treatment focuses on “collection and treatment.” The synergistic treatment of both can mitigate environmental risks and maintain the stability of the composting system, thus building a strong environmental protection barrier for organic fertilizer production lines.

Don’t neglect maintenance! The key to long-term operation of compost turning machines

Written by fertilizer production line on January 26th, 2026.

As a core piece of equipment in organic fertilizer production lines, the operating status of compost turners directly determines composting efficiency and finished product quality. Many composting projects suffer from frequent equipment failures and shortened lifespans due to neglected routine maintenance, increasing operating costs and disrupting production processes.

Maintenance is crucial for ensuring production efficiency. Compost materials often contain impurities and are highly moist and viscous, making them prone to wear on turning teeth, bearing jamming, and hydraulic system leaks over time. Regular cleaning, lubrication, and component inspection ensure uniform mixing and stable power, preventing uneven fermentation and prolonged composting periods caused by equipment failures, thus maintaining efficient production line operation.

Maintenance can significantly reduce overall costs. The repair costs (parts + labor) for sudden failures are several times higher than routine maintenance costs, and downtime can easily lead to a chain reaction of losses, including raw material accumulation and finished product supply disruptions. Regularly identifying potential hazards reduces the failure rate, extends equipment lifespan, and allows for more reasonable allocation of depreciation costs.

Maintenance can mitigate safety and environmental risks. Aging components can easily lead to safety accidents such as material splashing and equipment tipping over. Hydraulic oil leaks and motor overheating can also cause secondary pollution, violating environmental compliance requirements. Proper maintenance allows for timely replacement of aging components and resolution of leaks, ensuring personnel safety.

In summary, compost turning machine maintenance is a crucial link connecting equipment stability, production efficiency, and cost control. Whether for small projects or large-scale production lines, prioritizing daily maintenance and establishing standardized procedures are essential to ensuring the continued value of organic fertilizer compost turning equipment and providing a solid foundation for compost production.

Sludge to fertilizer: A priority for the circular economy?

Written by fertilizer production line on January 22nd, 2026.

The core of the circular economy is “closed-loop resource flow and maximized value utilization,” and sludge, as the end product of wastewater treatment, has always been a challenging issue in the environmental protection field. Can converting sludge into fertilizer become a priority for the circular economy? The answer requires a comprehensive assessment—provided that harmless treatment is ensured, this conversion path undoubtedly possesses the core logic to become a priority.

From a resource recovery perspective, sludge contains abundant organic matter, nitrogen, phosphorus, and other nutrients, which are core raw materials for organic fertilizer production lines. Converting sludge into fertilizer achieves a precise closed loop of “waste-to-resource,” avoiding nutrient loss and resource waste caused by sludge landfilling and incineration, perfectly aligning with the core goal of the circular economy: “turning waste into treasure.”

From an environmental burden reduction perspective, traditional sludge disposal methods (landfilling, incineration) easily cause leachate pollution of soil and water bodies and the emission of harmful gases. Converting sludge into fertilizer can significantly reduce the environmental pressure of sludge disposal, while also reducing the reliance on mineral resources for fertilizer production, forming a green chain of “wastewater treatment – sludge resource utilization – agricultural application,” providing a crucial path for the ecological benefits of the circular economy.

It must be emphasized that the prerequisite for “priority” is harmless treatment. It is essential to build a strong defense line through technologies such as high-temperature composting and heavy metal removal. The high-temperature composting process often requires key organic fertilizer production equipment such as compost turning machines to ensure even heating and thorough composting of the sludge, ultimately ensuring that the sludge fertilizer meets safety standards and avoids secondary pollution.

How compost turning machines improve the production efficiency of powdered fertilizers?

Written by fertilizer production line on January 19th, 2026.

In the production of powdered fertilizers, the efficiency of the fermentation process and the quality of raw material decomposition directly determine the pace of subsequent processing. As a core production auxiliary equipment, compost turning machines improve overall production efficiency from multiple key points by optimizing the fermentation process, improving raw material characteristics, and connecting production processes.

Accelerating raw material decomposition. Powdered fertilizer raw materials are mostly organic materials such as livestock and poultry manure and crop straw. Natural fermentation cycles are long and prone to uneven decomposition. Compost turners, through deep turning and mixing, can quickly break up material clumps, allowing the material to fully contact the air, increasing microbial activity, and promoting the rapid decomposition of organic matter.

Optimizing raw material characteristics. During the turning process, the compost turning machine can simultaneously mix and crush the materials, reducing clumping and resulting in more uniform particle size of the decomposed raw materials, eliminating the need for additional crushing and screening processes. This pre-treatment optimization makes the raw materials more suitable for subsequent grinding and fertilizer mixing equipment for powdered fertilizers, preventing equipment blockage or processing difficulties, improving the processing efficiency of subsequent processes, and reducing energy consumption and material loss.

Ensuring continuous production. Compost turners can achieve continuous and large-scale operation without frequent shutdowns for adjustments, stably supplying qualified raw materials to subsequent processes and avoiding production interruptions due to raw material shortages. At the same time, its flexible operating mode can adapt to different scales of production needs, ensuring smooth production flow whether in small and medium-sized decentralized production or large-scale fertilizer production lines.

What are the core values of chicken manure in the fertilizer industry?

Written by fertilizer production line on January 19th, 2026.

In the wave of resource utilization of agricultural waste, chicken manure is no longer a pollution hazard, but a highly valuable raw material in the fertilizer industry. Its rich nutrient reserves and suitable physical and chemical properties give it an important position in the production of high-quality organic fertilizers.

Core Value One: High-quality nutrient supply, meeting crop needs. Chicken manure is rich in core nutrients such as nitrogen, phosphorus, and potassium, and its organic matter content is as high as 25%-30%, far exceeding that of ordinary livestock and poultry manure. After scientific composting, the nutrients are more easily absorbed by crops, providing comprehensive nutrition for crop growth and supplementing soil organic matter, improving soil compaction and acidification problems.

Core Value Two: Prominent ecological value, contributing to circular agriculture. If chicken manure from large-scale farming is piled up indiscriminately, it can easily cause water and soil pollution. However, using chicken manure organic fertilizer machines to convert it into organic fertilizer can achieve a circular economy in farming, reduce the use of chemical fertilizers, and reduce agricultural non-point source pollution.

Core Value Three: Lowering production thresholds and improving economic efficiency. Chicken manure is widely available and inexpensive, which can significantly reduce the raw material costs of organic fertilizer production lines. For small and medium-sized fertilizer producers, using chicken manure as the core raw material can simplify the pre-treatment process, and high-quality organic fertilizer can be produced with conventional compost turn ing machines and granulators; for farmers, converting chicken manure on-site can also reduce fertilization costs and increase planting income.

The value of chicken manure in the fertilizer industry is essentially a vivid embodiment of “waste resource utilization.”
