Degradable Bags Become Organic Fertilizer After Use Safety and Environmental Protection

The process of biodegradable bags turning into organic fertilizer in soil mainly relies on their biodegradation characteristics. This process not only reduces the pollution of plastic waste to the environment, but also provides rich organic matter to the soil, improving soil structure and fertility.The following is a summary of relevant research and applications:

1. Composting process of biodegradable bags

Degradable bags (such as corn starch, calcium carbonate, polylactic acid PLA, and polycaprolactone PCL) can be decomposed into small molecular substances under composting conditions, ultimately converted into carbon dioxide, water, and organic matter. Research has shown that these bags can achieve up to 98% polymer to small molecule conversion within a few days in standard soil compost and household tap water. This process not only reduces the pressure on landfills, but also generates nutrient rich compost for soil improvement.

2. Improvement effect on soil

The organic matter decomposed from biodegradable bags can significantly improve soil quality. For example, compostable biodegradable bags can increase the organic carbon content in soil, improve soil structure, enhance soil water retention capacity and fertility. In addition, these organic matter can promote the activity of soil microorganisms, further accelerating the decomposition of organic matter and nutrient cycling in the soil.

3. Environmental benefits

Compared with traditional plastic bags, biodegradable bags decompose faster in the natural environment and do not accumulate for a long time like traditional plastics, resulting in microplastic pollution. Research has shown that the degradation process of biodegradable bags in soil is relatively mild, does not release harmful chemicals, and is more environmentally friendly.

4. Practical application

Some biodegradable bags have already passed relevant certifications, such as the European Union (DIN CERTCO, TUV), the United States (BPI), Australia (ABA) and other countries or regions' degradation certifications, ensuring that they can be completely decomposed in composting systems without leaving toxic residues. These bags have broad application prospects in agriculture and horticulture, and can serve as carriers for organic fertilizers to promote crop growth.

5. Research prospects

Although biodegradable bags have significant advantages in composting and soil improvement, their degradation process and long-term impact on soil ecosystems still need further research. For example, some studies have shown that biodegradable bags degrade faster under high temperature conditions, but their surface oxidation and fragmentation processes require further investigation.

In summary, the process of biodegradable bags turning into organic fertilizer in soil not only reduces the pollution of plastic waste to the environment, but also provides rich organic matter to the soil, improving soil quality, and is a sustainable environmental solution.

The safety of biodegradable bags is mainly reflected in the following aspects:

Environmental safety

• Natural degradation: Biodegradable bags can be decomposed by microorganisms in the natural environment and ultimately converted into harmless substances such as carbon dioxide, water, and inorganic salts. They will not accumulate in the soil for a long time like traditional plastic bags, causing damage to soil structure and fertility, nor will they float in the ocean for hundreds of years, endangering marine life.

• Reduce pollution: Its degradation process does not produce a large amount of harmful gases or residues, effectively reducing the burden on landfills and the potential harmful gas emissions during waste incineration, greatly reducing the risk of environmental pollution.

Use Security

• Non toxic and harmless: Degradable bags produced in a formal manner usually use natural plant starch, polylactic acid and other non-toxic and harmless raw materials. These raw materials undergo strict quality control during the production process and will not release harmful chemicals to the human body, such as phthalates and bisphenol A, making them safer and more reliable to use.

Food safety: Some biodegradable bags have also passed food safety certification and can be used to hold food. Their materials will not undergo chemical reactions when in contact with food, and will not have adverse effects on the quality and safety of food, ensuring the hygiene and safety of food during storage and transportation.

Production process safety

Green production: The production process of biodegradable bags is relatively environmentally friendly, with lower energy consumption and greenhouse gas emissions compared to traditional plastic bag production. The wastewater, exhaust gas and other pollutants generated during the production process are also relatively small, with minimal impact on the surrounding environment, which meets the requirements of sustainable development.

Strict quality supervision: With the increasing awareness of environmental protection and the improvement of relevant regulations, the production of biodegradable bags is subject to strict supervision. Production enterprises need to follow strict quality standards and environmental requirements to ensure the quality and safety of their products. Regulatory authorities will also conduct regular spot checks on biodegradable bags in the market, and products that do not meet the standards will be prohibited from sale, thereby ensuring that consumers can use safe and reliable biodegradable bags.
