1. Impact on the soil environment
If non-woven bags are not properly handled after being discarded, they will have a certain impact on the soil environment. Most non-woven bags are made of synthetic materials such as polypropylene, which are difficult to degrade quickly in the natural environment. When non-woven bags enter the soil, they will change the physical structure of the soil. They will hinder the air circulation in the soil and affect the respiration of microorganisms in the soil. For example, aerobic microorganisms in the soil need sufficient oxygen to decompose organic matter. The presence of non-woven bags may cause local soil to be in anoxic state, thereby inhibiting the activity of these microorganisms. At the same time, if non-woven bags do not decompose in the soil for a long time, it will also affect the water penetration of the soil, causing water to accumulate or lose unevenly on the surface of the soil, posing a potential threat to the growth of crops and the balance of the soil ecosystem.
2. Pressure on the garbage disposal system
The large amount of waste of non-woven bags has brought obvious pressure to the garbage disposal system. In the landfill, non-woven bags take up a lot of space. Due to their non-degradable characteristics, they will exist in the landfill for a long time, reducing the effective storage capacity of the landfill. Unlike organic waste that can be degraded quickly, Non-woven bags do not significantly reduce in volume over time, which means that more landfill sites need to be opened up to accommodate the continuous generation of garbage. In terms of incineration treatment, although Non-woven bags can be burned, some harmful substances such as dioxins may be produced during the combustion process. If these substances are discharged into the atmosphere, they will harm air quality and human health, and in order to deal with these harmful substances, waste incineration plants need to be equipped with more complex waste gas treatment equipment, which increases the cost of treatment.
3. Threats to wildlife and marine ecology
Discarded Non-woven bags are also a threat to wildlife. In the natural environment, animals may mistake Non-woven bags for food or be entangled by them. For example, birds may use fragments of Non-woven bags to build nests, and these fragments may cause harm to young birds during hatching or growth. In the marine environment, Non-woven bag fragments may be eaten by marine organisms, causing blockage in their digestive systems and affecting their normal growth and reproduction. In addition, a large amount of Non-woven bag garbage may also damage the marine landscape and affect the development of industries such as marine ecotourism.
4. Damage to the visual landscape
From an aesthetic point of view, discarded non-woven bags will damage the visual landscape of the environment. Whether in city streets, parks or rural fields, the non-woven bags garbage everywhere will give people a dirty and messy feeling. They are scattered on the roadside, grass or beach, affecting people's aesthetic experience of natural landscape and urban environment, reducing the overall quality of the environment, and also reflecting the environmental management and civilization level of a region.
