Impact on the environment The natural turf consists of green plants that absorb carbon dioxide through the physiological metabolic process of photosynthesis, emit oxygen, and absorb toxic gases such as sulfur dioxide, hydrogen fluoride, ammonia, chlorine, etc., to purify the air The role. Natural turf has a significant effect on the dust, the measured data show that in the scraping three or four winds, the bare soil over the dust concentration over the lawn 13 times. Studies have shown that 25 square meters of lawn can be a person out of the total absorption of carbon dioxide, into oxygen, to meet the human respiratory process required oxygen. Artificial turf is made of polyethylene, polypropylene and other polymers made of non-living matter, can not carry out the green plant metabolism activities, it does not have the role of regulating the balance of carbon and oxygen in the atmosphere. Although the artificial turf can block the dust to a certain extent, but do not have the function of absorbing toxic gases to purify the atmosphere. In addition, the low level of artificial turf fiber often contain chlorine impurity, in high temperature, strong sunshine conditions will decompose and release chlorine, damage to air quality.
Impact on the climate The turf of the natural lawn is a mixture of sediment, the structure of the pores can be in the irrigation and precipitation process to accumulate moisture, play a role in the conservation of water. When the climate is hot, the turfgrass absorbs the moisture in the depths of the roots, and takes a lot of heat from the surrounding environment by transpiration, effectively reducing the ground temperature and regulating the microclimate in a certain range. The turf structure of artificial turf consists of rubber, concrete or asphalt, which can not play the role of water conservation. Therefore, it can not reduce the surface temperature, and its heat capacity is small, which leads to the surface temperature is much higher than the air temperature, especially in the closed stadium The problem is more serious.
The final product of the natural lawn produced by the residual grass in the bed of sediment in the decomposition of microorganisms, into organic matter back to the soil. The final remaining non-toxic, harmless mixture of sediment, which can be added to the organic matter improved after another use.
The main ingredient of artificial turf is polyethylene non-biodegradable materials, after 8 to 10 years of aging eliminated, the formation of tons of high polymer waste. Foreign companies are generally recovered by the professional company degradation, and then to achieve the use of renewable resources, the domestic road can be used as road fillers. Such as the site to other uses need to remove the base layer built from asphalt or .
