With the rise of red wine, red wine packaging is also widely used accordingly. Nowadays, more and more people choose red wine boxes to package red wine for sales and gifts. However, as people’s requirements for quality of life are getting higher and higher. , As well as people’s recognition of the concept of health and environmental protection, everyone is increasingly paying attention to the health of the product. The first choice when people choose is to make it harmless to human health. And the environmental protection of the product, to see if it has an impact on the environment.
It is well known that plastic products contain many harmful substances, and they also cause great damage to the environment. The pvc material, which is widely used in the red wine skin box of red wine packaging, is also a kind of plastic product. At present, the main factors affecting the human body and the environment in plastic products are substances such as dioxins. So does it have an impact on the health of the human body and on the environment?
The chemical industry as a whole, especially the PVC production chain, has only very slight dioxin emissions, which are far less than 1% in the world. As an example, a survey conducted in 1993 attributed the entire chemical industry to only 0.5 g/year in 2001 and a total of 484 g of dioxin emissions in the Netherlands each year. American PVC manufacturers have carried out extensive monitoring procedures to assess the level of dioxin emissions and the impact on the environment. The most likely estimate is 32 grams, about 12 grams of I-TEQ/yr are released into the open environment and 19 grams are safely landfilled. In comparison, the total amount released into the air is only a few kilograms. The recent ecological archives of the PVC industry show that in the production of PVC in Western Europe, the total emissions of dioxins now form about 2 grams of TEQ each year and only a very small amount of dioxins can be produced. This is in the case of ethylene oxide chlorine. One of the process steps leads to the production of VCM. These dioxin molecules are adsorbed by solid catalysts, so they can be easily filtered and processed. The production and use of PVC and PVC products are much lower than the temperature required for the formation of dioxin.
Any waste may contain chlorine, including dioxins when wood and food residues are burned. Although the amount of chlorine in the waste exceeds a few percent of a threshold, this is not an important factor. The main factor is the operating conditions of the incinerator. One of the most important factors in the formation of dioxins is the temperature of the combustion gas. Oxygen concentration also plays an important role in the formation of dioxins, but the design of modern incinerators minimizes the chlorine content and optimizes the stability of PCDD/F formation during the thermal process. Under the operating conditions of modern incinerators, the formation of dioxins can be minimized, and pollution control devices are equipped to capture the harmful substances produced. In addition, a study commissioned by the EU authorities shows that perishables account for 35% of emissions, while plastics account for only 25%. Some studies also show that removing PVC from waste will not significantly reduce dioxin emissions.
