Codipac - a hygienic, reusable packaging solution designed to replace disposable plastics in grocery supplies.

将减少、再利用、再循环的废物等级应用于食品包装是一项具有挑战性的工作。减少包装将导致更短的保质期和更多的食物浪费，其影响比减少包装更严重。目前46.2%的食品包装被回收，其余的被焚烧、掩埋或出口，命运不明。由于对卫生的担忧，几乎没有食品包装被重复使用。重复使用的包装需要使用者之间的消毒才能被消费者接受。高温洗涤或化学杀菌对环境的影响意味着不利于重复使用食品包装。CodiKoat开发了一种名为Cydal的新型抗菌技术。它可以作为许多材料的表面涂层，杀灭病毒或细菌。我们已经证明，经过赛达尔处理的材料对人类来说是安全的。在这个项目中，我们将开发含有赛达尔的新型食品包装材料。我们将设计适合于杂货递送的容器。我们将与超市和消费者合作，看看如何用我们的可重复使用的替代品取代目前的食品包装。我们将确定用户之间需要多少洗涤，以防止细菌或病毒在用户之间传播。我们还将确定包装可以安全使用的次数，并设计一个系统来指示何时需要更换。我们还将计算我们的新食品包装对环境的改善程度。我们有来自两个超市的强烈兴趣，一旦我们完成这个项目，就会使用我们的技术。

It is challenging to apply the waste hierarchy of _reduce, reuse, recycle_ to food packaging. Reduction would lead to shorter shelf life and greater food waste, with worse impact than the reduction in packaging. 46.2% of food packaging is currently recycled, with the remainder incinerated, buried in landfill or exported with unknown fate. Virtually no food packaging is re-used, due to concerns around hygiene. Re-used packaging requires sterilisation between users to be acceptable to consumers. The environmental impact of high temperature washing or chemical sterilisation means it is not beneficial to re-use food packaging.CodiKoat have developed novel antimicrobial technology called Cydal. This can be applied as a surface coating to many materials and kills viruses or bacteria. We have already shown that materials treated with Cydal are safe for humans to handle. In this project, we will develop new food packaging materials that contain Cydal. We will design containers suitable for use in grocery delivery. We will work with supermarkets and consumers to see how we could replace current food packaging with our re-usable alternative. We will determine how much washing is needed between users to prevent bacteria or viruses being passed between users. We will also determine how many times packaging can be used safely and design a system to indicate when it needs replacing. We will also calculate how much better for the environment our new food packaging could be. We have strong interest from two supermarkets to use our technology once we have completed this project.
