The rise of the take-away industry has facilitated our lives. We only need to move our fingers and food will be delivered to our doors! However, behind the convenience, there is a problem that cannot be ignored, that is, take-away garbage! Just how much garbage can a small takeaway produce?
according to statistics, the number of online take-out users in the first half of 2118 was 363.87 million, an increase of 21.49 million compared with 343.38 million at the end of 2117, accounting for 45.4% of the total netizens, an increase of 1.9% compared with the end of 2117. According to conservative estimation, if you are hungry, Meituan's take-out platform is about 21 million units/day. If each unit has 1 plastic bags and each plastic bag is 1.16㎡, the total area of plastic bags used is about 1.2 million ㎡/day, which can cover 168 football fields. In addition, if each unit takes out an average of 3.27 disposable plastic lunch boxes/cup, the consumption of lunch boxes will exceed 61 million units/day. At the same time, in order to attract customers, some "online celebrity" stores over-package take-away food, resulting in more unnecessary garbage ... Control of take-away garbage must be put on the agenda.
Some people question this. The take-away box is made of degradable material or recyclable plastic material. Is it sensational to keep emphasizing the data of take-away lunch boxes?
In fact, although degradable lunch boxes have been put into production, the utilization rate and popularization rate are not optimistic because of its high cost. At present, the degradable lunch boxes used by most stores are facing different difficulties in the process of recycling, degradation and incineration to generate electricity.
as a degradable plastic in theory, PP can be said to be environmentally friendly. But it is not completely without impact on the environment. According to the waste management office of Xi 'an Urban Management Bureau, it takes 31 years for PP plastics to be buried and degraded. The most common non-plastic domestic waste, such as skins and bamboo sticks, can be degraded in one or two years. The degradation time of 31 years is also affecting the land use efficiency.
garbage power plants mainly generate electricity by burning garbage. Then, what will happen to the burning of commonly used PP takeout boxes? As an organic polymer, the incomplete combustion of PP take-out box is easy to produce toxic gases such as black smoke or carbon monoxide. The essence of black smoke is carbon, which has strong reducibility at high temperature and can lead to more harmful gases, such as dioxins.
Take-away food is convenient for our work and life, but take-away garbage is potentially damaging our living environment. What should we do about the disposal of take-away garbage?
