可降解顆粒塑料是指其制品的各項性能可滿足使用性能要求，在保存期內性能不變，而使用后在自然環境條件下能降解成對環境無害的物質的塑料。那么可降解顆粒制品現如今能用嗎？

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?

這類淀粉基可降解顆粒塑料是在傳統PE（聚乙烯）等單體聚合過程中加入淀粉等添加劑進行改性，使塑料在環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.

但是在后來的研究中發現，成為碎片后的塑料無法完全降解，會形成微塑料等繼續毒害環境。因此淀粉改性塑料也被稱為“生物破壞性塑料”（不完全降解型）。第二代降解塑料為光熱降解塑料，因對溫度、光照強度等降解條件要求十分嚴苛，發展也十分緩慢。

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.

可降解顆粒塑料對普通塑料的替代不可能一蹴而就，需要分步實現，需要禁止和替代的就是一次性用品，包括塑料袋、餐具、快遞袋、編織袋、膠帶等等。

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.

可降解顆粒塑料前期一直發展很慢，主要原因就是生產成本較高，推行政策不夠強力，為了解決比較嚴重的廢物問題就開始禁止進口洋垃圾，這使得發達的處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年開始歐洲陸續推出針對塑料的強制政策，國內政策也開始越來越嚴格，因此我們認為可降解顆粒塑料已經進入了行業爆發期，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豐富的羥基、羧基等活性基團，開發具有針對性的生物可降解顆粒塑料專用多功能助劑顯得尤為重要，同時在填充和回收領域要兼顧和低成本化。更多關于相關內容就來我們網站http://tecnoleo.com咨詢吧！

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 http://tecnoleo.com Consult!
