可降解外卖打包袋的常规问题
来源:www.sdynbz.com 发布时间:2022-09-15 浏览次数:122
近阶段餐饮外卖行业发展的迅猛,各大外卖平台竞争的非常激烈,这也就给了消费者提供了更多的生活便利。但是一次的外卖会产生出很多一次性餐具和包装袋,对于环境的和人体健康带来了很大的负面影响,对于可降解外卖打包袋的常规问题我们一起来看看这其中的内容。
The rapid development of the catering takeout industry in the recent stage and the fierce competition among the major takeout platforms have also provided consumers with more convenience in life. However, a single take away will produce a lot of disposable tableware and packaging bags, which has a great negative impact on the environment and human health. Let's take a look at the general problems of degradable take away packaging bags.
1、是否只能堆肥化处理
1. Can only be composted
这是不一定的,可以在堆肥条件下降解,也可以在其它条件下进行降解,也能够在自然环境如土壤和海水等条件下生物降解,但是具体和塑料的化学结构、制品的配方等降解环境是有关系的,因此说只能在堆肥化处理是不对的,在以上讲的条件下都是可以进行降解的。
This is not necessarily. It can be degraded under composting conditions, or under other conditions, or under natural conditions such as soil and sea water. However, it is related to the chemical structure of plastics, the formula of products and other degradation environments. Therefore, it is wrong to say that composting treatment can only be used, and it can be degraded under the above conditions.
2、在厌氧消化装置中是不是能够完全降解
2. Can it be completely degraded in anaerobic digestion device
降解外卖打包袋能够被微生物降解的主要原因是因为其化学结构和传统塑料的不同,因此可以被微生物所降解。目前的讲解材料中,大多数都是可以在厌氧消化装置下被降解。
The main reason why the degradable takeaway packaging bag can be degraded by microorganisms is that its chemical structure is different from that of traditional plastics, so it can be degraded by microorganisms. Most of the current materials can be degraded in anaerobic digestion devices.

3、在土壤中是不是能够完全降解
3. Can it be completely degraded in soil
在天然土壤、温度、水分和微生物等不可控条件下,堆肥过程中可控条件的条件相对不可控。目前大部分可降解塑料在田间土壤条件下是可生物降解的,如PBAT、PHA、PCL、PBS等,在正常气候条件下埋入土壤5个月即可完全降解,不会对植物产生影响;PLA材料降解比较慢,需要很长时间,但与PBAT等材料混合后,半年左右就可以完全降解。
Under the uncontrollable conditions of natural soil, temperature, moisture and microorganism, the controllable conditions in composting process are relatively uncontrollable. At present, most degradable plastics are biodegradable under field soil conditions, such as PBAT, PHA, PCL, PBS, etc. They can be completely degraded after being buried in soil for 5 months under normal climatic conditions, without any impact on plants; PLA degrades slowly and takes a long time, but it can be completely degraded after mixing with PBAT and other materials for about half a year.
