Plastics play important roles in modern life and currently the development of plastic recycling is highly demanding and challenging. To relieve this dilemma, one option is to develop new sustainable bioplastics that are compatible with the environment over the whole material life cycle. We report a sustainable bioplastic made from natural DNA and biomass-derived ionomers, termed as DNA plastics. The sustainability involves all aspects of the production, use, and end-of-life options of DNA plastics: (1) the raw materials are derived from biorenewable resources; (2) the water-processable strategy is environmentally friendly, not involving high-energy consumption, the use of organic solvents, and the production of byproducts; (3) recyclable and nondestructive use is achieved to significantly prolong the service lifetime of the plastics; and (4) the disposal of waste plastics follows two green routes including the recycling of waste plastics and enzyme-triggered controllable degradation under mild conditions. Besides, DNA plastics can be “aqua-welded” to form arbitrary designed products such as a plastic cup. This work provides a solution to transform biobased hydrogel to bioplastic and demonstrates the closed-loop recycling of DNA plastics, which will advance the development of sustainable materials.

由生物质 DNA 和离聚物制成的可持续生物塑料
塑料在现代生活中发挥着重要作用，目前塑料回收的发展要求很高，充满挑战。为了缓解这一困境，一种选择是开发在整个材料生命周期内与环境兼容的新型可持续生物塑料。我们报告了一种由天然 DNA 和生物质衍生的离聚物制成的可持续生物塑料，称为 DNA 塑料。可持续性涉及 DNA 塑料的生产、使用和报废选择的各个方面：（1）原材料来自生物可再生资源；(2) 水处理策略是环保的，不涉及高能耗、不使用有机溶剂和产生副产品；(3) 实现可回收和无损使用，显着延长塑料的使用寿命；（4）废塑料处理遵循废塑料循环利用和温和条件下酶促可控降解两条绿色路线。此外，DNA塑料可以“水焊”形成任意设计的产品，例如塑料杯。这项工作提供了一种将生物基水凝胶转化为生物塑料的解决方案，并展示了 DNA 塑料的闭环回收利用，这将推动可持续材料的发展。
