可降解颗粒制品现如今能用吗？

可降解颗粒塑料是指其制品的各项性能可满足使用性能要求，在保存期内性能不变，而使用后在自然环境条件下能降解成对环境无害的物质的塑料。那么可降解颗粒制品现如今能用吗？

Degradable granular plastics refer to the plastics whose properties of products can meet the performance requirements of use, remain unchanged during the storage period, and can be degraded into harmless substances under natural environmental conditions after use. Can degradable particulate products be used now?

这类淀粉基可降解颗粒塑料是在传统PE（聚乙烯）等单体聚合过程中加入淀粉等添加剂进行改性，使塑料在环境中可裂解成微小的塑料碎片。

This kind of starch based degradable granular plastics is modified by adding additives such as starch in the traditional monomer polymerization process such as PE (polyethylene), so that the plastic can be cracked into tiny plastic fragments in the environment.

但是在后来的研究中发现，成为碎片后的塑料无法完全降解，会形成微塑料等继续毒害环境。因此淀粉改性塑料也被称为“生物破坏性塑料”（不完全降解型）。第二代降解塑料为光热降解塑料，因对温度、光照强度等降解条件要求十分严苛，发展也十分缓慢。

However, in the later research, it was found that the plastic that became fragments could not be completely degraded, and micro plastic would continue to poison the environment. Therefore, starch modified plastics are also called "bio destructive plastics" (incomplete degradation type). The second generation of degradable plastics is photothermal degradable plastics. Due to the strict requirements for degradation conditions such as temperature and light intensity, the development is also very slow.

可降解颗粒塑料对普通塑料的替代不可能一蹴而就，需要分步实现，需要禁止和替代的就是一次性用品，包括塑料袋、餐具、快递袋、编织袋、胶带等等。

The substitution of degradable granular plastics for ordinary plastics cannot be achieved overnight. It needs to be achieved step by step. The first thing to be prohibited and replaced is disposable products, including plastic bags, tableware, express bags, woven bags, adhesive tapes, etc.

可降解颗粒塑料前期一直发展很慢，主要原因就是生产成本较高，推行政策不够强力，为了解决比较严重的废物问题就开始禁止进口洋垃圾，这使得发达国家的处理成本突然大幅提升。

The development of degradable granular plastics has been very slow in the early stage, mainly because of the high production cost and the weak implementation of policies. In order to solve the serious waste problem, China began to ban the import of foreign garbage, which made the treatment cost of developed countries rise sharply.

所以可以看到18年开始欧洲国家陆续推出针对塑料的强制政策，国内政策也开始越来越严格，因此我们认为可降解颗粒塑料已经进入了行业爆发期，而聚乳酸（PLA）和PBAT是其中有前景的材料。

So it can be seen that since the beginning of 2018, European countries have successively introduced mandatory policies for plastics, and domestic policies have become more and more strict. Therefore, we believe that degradable particulate plastics have entered the industry explosion period, and polylactic acid (PLA) and PBAT are promising materials.

生物可降解高分子大多含有丰富的羟基、羧基等活性基团，开发具有针对性的生物可降解颗粒塑料专用多功能助剂显得尤为重要，同时在填充和回收领域要兼顾和低成本化。更多关于相关内容就来我们网站 //www.ucgmex.com咨询吧！

Biodegradable polymers mostly contain rich hydroxyl, carboxyl and other active groups. It is particularly important to develop targeted multifunctional additives for biodegradable particulate plastics. At the same time, in the field of filling and recycling, high efficiency and low cost should be taken into account. Come to our website for more information //www.ucgmex.com Consult!
