可降解塑料袋回收利用
Recycling of degradable plastic bags
1.产量太少,目前缺乏系统的大规模回收处理手段。举个简单的例子,在上海进行垃圾分类的时候,很多人在扔垃圾的时候,会苦恼要把食物残渣从垃圾袋里抖出来,很容易弄脏手。于是生物降解性湿垃圾袋开始着火,人们希望生物降解性垃圾袋和湿垃圾一起扔进湿垃圾桶。但是垃圾处理部迅速发声说,“可分解垃圾袋”大部分可以分解,但有不可分解,甚有毒有害成分,会影响湿垃圾的处理。另外,这种垃圾袋的分解速度比厨房剩下的垃圾慢得多,不能同时处理,只能作为干垃圾焚烧处理。生物降解塑料可以生物降解,但这并不意味着打破回收处理的困难,分解为阻碍。
1. The output is too small, and there is a lack of systematic large-scale recovery and treatment means at present. For a simple example, when sorting garbage in Shanghai, many people will be distressed to shake food residues out of garbage bags when throwing garbage, which is easy to get their hands dirty. Therefore, biodegradable wet garbage bags began to catch fire, and people hoped that biodegradable garbage bags and wet garbage would be thrown into the wet garbage can together. However, the waste disposal department quickly said that most of the "decomposable garbage bags" can be decomposed, but there are non decomposable, even toxic and harmful components, which will affect the treatment of wet garbage. In addition, the decomposition speed of this garbage bag is much slower than the garbage left in the kitchen. It cannot be treated at the same time and can only be incinerated as dry garbage. Biodegradable plastics can be biodegradable, but this does not mean that the difficulty of recycling is broken down into obstacles.
2.生物降解塑料不能有效回收,进入垃圾填埋场后,在无氧环境中分解大量温室气体3354甲烷。
2. Biodegradable plastics cannot be effectively recycled. After entering the landfill, they decompose a large amount of greenhouse gas 3354 methane in an oxygen free environment.
3.生物降解塑料不能有效回收,进入海洋环境后海洋温度低,缺乏足够的微生物和氧气,生物降解的效率大大降低。由于不能及时分解,这些可分解塑料在还未分解之前很有可能对海洋生物造成危害。
3. Biodegradable plastics cannot be effectively recycled. After entering the marine environment, the ocean temperature is low, and there is a lack of sufficient microorganisms and oxygen, which greatly reduces the efficiency of biodegradation. Due to the failure to decompose in time, these biodegradable plastics are likely to cause harm to marine organisms before decomposition.
