Plastics offer many benefits to society and are widely used in our daily life: they are lightweight, cheap and adaptable. However, the production, processing and disposal of plastics are simply not sustainable, and pose a major global threat to the environment and human health. Eco-friendly processing of reusable and recyclable plastics derived from plant-based raw materials would be an ideal solution. So far, the technological challenges have proved too great. However, researchers at the University of G\u00f6ttingen have now found a sustainable method \u2013 \u201chydrosetting\u201d, which uses water at normal conditions \u2013 to process and reshape a new type of hydroplastic polymer called cellulose cinnamate (CCi). The research was published in Nature Sustainability.<\/strong><\/p>\n\n\n\n

Plastics are polymers, meaning that their molecular structure is built up from a large number of similar units bonded together. Currently, most plastics are manufactured using petrochemicals as raw materials, which is damaging to our environment to both extract and dispose of. In contrast, cellulose, which is the main constituent of plant cell walls, is the most abundant natural polymer on earth, constituting an almost inexhaustible source of raw material. By slightly modifying a very small portion of the chemistry of cellulose by introducing a \u201ccinnamoyl\u201d group, the researchers succeeded in making a specific CCi that is suitable for the formation of a new type of bioplastic with hydroplastic (ie soft and mouldable on contact with water) polymers.<\/p>\n\n\n\n

This means that it can be moulded using little more than water at everyday temperature and pressure. This unique method \u2013 known as hydrosetting \u2013 enabled the researchers to produce a variety of shapes simply by immersing the bioplastic in water and leaving it to dry in the air. The moulded shapes kept their stability in the long-term and could be reshaped over and over again into a variety of 2D and 3D shapes. Although the plastic should not be used for direct contact with water \u2013 because it will lose its shape \u2013 it can hold water and be used in humid conditions. The CCi bioplastics showed high quality mechanical properties when compared with plastics that are currently widely used.<\/p>\n\n\n\n

\u201cOur research provides a feasible method to design other eco-friendly hydroplastics from renewable resources,\u201d explains Professor Kai Zhang from the University of G\u00f6ttingen. \u201cThis should open up new avenues of research, stimulating further exploration of other sustainable bioplastics with superior mechanical properties and new features.\u201d<\/p>\n\n\n\n

The hydrosetting process avoids expensive and complex machinery and harsh processing conditions. This eco-friendly method highly simplifies plastics manufacture, making their processing and recycling more economical and sustainable. \u201cThis research offers tremendous potential for bioplastics like this to be applied in many different situations, such as biology, electronics and medicine,\u201d says Zhang before adding: \u201cIn particular, the detrimental effects of plastics on the environment, which is damaging to all forms of life on earth, would be minimized by reusing hydroplastics with their unique features.\u201d<\/p>\n\n\n\n
