While polyethylene catalysis is a mature field, global needs for stronger, lighter materials and growth in polyethylene demand drives ongoing innovation in catalyst design. Such ongoing innovation has enabled, and continues to enable, the replacement of heavier materials with (such as glass and cardboard) in product packaging, thereby offering a significant environmental advantage in terms of fuel efficiency and reduced greenhouse gases in product transport. Furthermore, not all plastic food packaging is currently recyclable due to the need to mix polyolefin materials with other materials in order to create good barrier properties and keep food fresh. Improvements in catalyst technology, that could be achieved through new ligand frameworks, could be used to produce multifunctional polyolefins that are also 100% recyclable. This would have a tremendous effect on reducing the amount of material going into landfills, and would reduce the amount of virgin plastic resin needed by allowing recycling of existing material.

虽然聚乙烯催化是一个成熟的领域，但全球对聚乙烯需求中较轻材料和生长的需求是催化剂设计中正在进行的创新。 这种持续的创新已启用并继续使产品包装中的较重材料（例如玻璃和纸板）更换，从而在燃油效率和产品运输中的温室气体降低方面具有很大的环境优势。 此外，由于需要将聚烯烃与其他材料混合以创建良好的屏障特性并保持食物新鲜，因此并非所有塑料食品包装目前都可以回收。 可以通过新的配体框架来实现的催化剂技术的改进，可用于生产多功能聚芬，也可以100％可回收。 这将对减少进入垃圾填埋场的材料量产生巨大影响，并通过允许回收现有材料来减少所需的原始塑料树脂量。
