“…Bacteria‐driven biomineralization is another fast‐growing field of research for biomatter‐based materials and composites. For example, CaCO 3 precipitation of certain bacterial strains when grown in favorable conditions, is an emerging research field with applications in self‐healing materials, such as bioconcrete, other structural applications, as well as heavy metal removal 249 . We refer the reader to recent reviews on this topic 250–252 as these works focus on utilizing the inorganic product catalyzed by the bacterial activity rather than the actual microorganism as a building block by itself, which is the thesis of our review.…”

The mass production and disposal of non‐degradable fossil‐based plastics is responsible for alarming environmental and social issues when not managed responsibly. Towards manufacturing environmentally‐friendly materials, biopolymers, that is, polymers synthesized by living organisms, emerge as promising sustainable alternatives as they combine attractive mechanical properties, compostability, and renewable sourcing. In this review, we analyze the structural and mechanical properties of three of the most studied biopolymer classes: cellulose, chitin, and protein beta‐sheet structures. We first discuss the hierarchical structure of the biopolymers and how their rich interaction networks induce appealing mechanical properties. Then, we review different fabrication and processing methods to translate these attractive properties into macroscopic materials and composites. Finally, we discuss a nascent approach, which leverages the direct use of microorganisms, in the form of intact cells, tissues or dissociated biological matter (biomatter), as meso‐scale material building blocks. These non‐ or little pre‐processed biomatter building blocks are composed of the biopolymer structural elements (molecular‐nano scale), but also inherit the higher‐scale hierarchical characteristics. Processing‐structure–property relationships for biomatter‐based materials are discussed, emphasizing on the role of hierarchical arrangement, processing‐induced transformations, and intermolecular bonding, on the macroscopic mechanical properties. Finally, we present a perspective on the role of biopolymers in a circular economy.

“…For example, self-healing materials can be used to fix damages on wearable devices and allow for new shape and function reconfigurations of a handheld controller by breaking and rejoining the dynamic bonds. [21,94,95] (iii) Systems designed with morphing matter that evolve over time, through techniques such as self-organizing, [96] phase shifting, [97] self-growth, [98,99] and controlled degradation, destruction, and evolution [100,101] may also achieve multi-functionalities. Additionally, morphing matter can promote sustainability by serving ecological purposes.…”

Morphing matter that change shapes and properties in response to external stimuli have gained significant interests in material science, robotics, biomedical engineering, wearables, architecture, and design. Along with functional advances, there is growing pressure and interest in considering the environmental impact of morphing matter during its life cycle. The unique manufacturing and usage of morphing matter means that existing sustainable design frameworks and principles for general physical products may not apply directly. For example, manufacturing morphing matter often requires designing and predicting materials' behaviors over time, and using devices fabricated with morphing matter often involves harnessing renewable energy and self‐reconfiguration, which pose unique sustainability opportunities and challenges. This study reflects and summarizes the field's practice in sustainable manufacturing, transport, use, and end‐of‐life handling of morphing matter. The term “sustainable morphing matter” (SMM) is coined, suggesting that sustainability‐conscious factors can become an integral component of morphing matter. In addition, ways to apply sustainability‐conscious factors to augment the existing design pipeline of morphing matter are presented, and more quantitative and algorithmic‐level developments are needed to apply these factors rigorously to the design process.

“…[ 16,17 ] However, this strategy renders the controlled incorporation of pores whose diameters span many orders of magnitudes difficult. In fact, these synthetic mineral‐based composites are either thin films [ 18‐20 ] or bulk materials [ 21,22 ] whose densities are too high for their use in locomotive applications. Even more limiting is the short diffusion length of ions within the scaffold that restricts the dimensions of bulk composites that can be homogeneously mineralized.…”

Nature fabricates hard functional materials from soft organic scaffolds that are mineralized. To enable an energy‐efficient locomotion of these creatures while maintaining their structural stability, nature often renders parts of these minerals porous. Unfortunately, methods to produce synthetic minerals with a similar degree of control over their multi length scale porous structure remain elusive. This level of control, however, would be required to design lightweight yet robust biominerals. Here, a room temperature process is presented that combines a localized mineralization with emulsion‐based 3D printing to form cm sized biominerals possessing pores whose diameters range from the 100 s of nm up to the mm length scale. The samples encompass up to 80 wt% of CaCO3 and display a specific compressive strength that is significantly higher than that of previously reported 3D printed porous biominerals and close to those of trabecular bones. The universality of this approach by forming different types of bioactive minerals, including calcite, aragonite, and brushite is demonstrated. The ability to 3D print these materials under benign conditions renders this energy‐efficient process well‐suited to construct cm‐sized lightweight yet load‐bearing structures that might find applications, for example, in the design of the next generation of flying or motile objects.
