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，但全球对更坚固、更轻的材料的需求以及聚乙烯需求的增长推动了催化剂设计的不断创新。这种持续的创新已经并将继续使产品包装中较重的材料（如玻璃和纸板）的替代成为可能，从而在燃料效率和减少产品运输中的温室气体方面提供了显著的环境优势。此外，目前并非所有的塑料食品包装都是可回收的，因为需要将聚烯烃材料与其他材料混合，以产生良好的阻隔性能并保持食品新鲜。催化剂技术的改进，可以通过新的配体框架来实现，可以用来生产100%可回收的多功能聚烯烃。这将对减少进入垃圾填埋场的材料数量产生巨大影响，并通过允许回收现有材料减少所需的原始塑料树脂的数量。
