Circular Design Strategy for Bio-Based Food Packaging Preproduction
The success factor of the industrial transition to circularity is that this new economy model is regenerative by design. The Circular Design Guide prepared by the Ellen MacArthur Foundation in cooperation with IDEO distinguishes six circular design strategies: Two circular design strategies are directly applicable in food packaging: smart material choice, considering a product’s end-of-life treatment in the choice of materials and inputs (for example, durable, biodegradable, recycled or recyclable materials) and closed loop or take back, referring to collections of old or used products and recovering the value of the materials by recycling or reusing them to make new products. The smart material choice circular design strategy (the choice of packaging material), which is applied in the preproduction life cycle stage, directly correlates with all circular re-strategies: firstly, packaging material savings (reduce) could be achieved if optimal material properties and minimum material usage were applied.

Water Treatment Using Functional Composites
Due to its low cost, biosorption technology has been extensively carried out to treat heavy metal-laden wastewater using biosorbents. The studies on heavy metal biosorption mechanisms and the simulation of mathematical modeling on the biosorption process have enhanced scientific understanding about the binding between target metal cations and the functional group on different surfaces of biomasses as a biosorbent.

Ammonia Inhibition
Anaerobic digestion is one of the most widely used treatment methods for animal manure. Chicken manure has high methane production potential and is thus a suitable substrate for biogas plants.

Hydrothermal Carbonization of Agricultural Biogas Production Process
In agricultural biogas plants, besides biogas, the by-product digestate is also produced. Due to its high moisture content and organic origin, it can successfully be applied in the hydrothermal carbonization process to avoid the fate of landfilling. The type of feedstock and the parameters of the hydrothermal conversion (HTC) process, such as temperature, pressure and residence time, affects the physical and chemical characteristics of hydrochar. Therefore, its possible application might be as a biofuel, fertilizer, soil improver, adsorber, or catalyst.

Sea Ice Motion Tracking Based on Satellite Videos
Sea ice tracking is essential for many regional and local level applications, including modeling sea ice distribution, ocean atmosphere, climate dynamics, as well as safe navigation and sea operations. Most operational sea ice monitoring techniques rely on satellite-borne optical and synthetic aperture radar (SAR) sensors, augmented by scatterometer and passive microwave imagery. Herein, previous ice tracking works are studied and classified into two categories: traditional tracking methods and DL-based tracking. Specifically, traditional ice tracking methods can be broadened to include cross correlation-based, optical flow-based and so on.

Biomaterials in 3D Printing
Additive manufacturing (AM), also known as 3D printing, encompasses a wide range of techniques for applications ranging from on-demand production to functional prototypes. 3D printing is mainly used in industrial sectors such as aerospace, automotive, medical, dental, construction, art and fashion. Fossil fuel-based materials, such as plastics and metals, as well as concrete, etc., are widely used to produce 3D-printed products. Innovative 3D technologies using new bio-based renewable materials have shown promising results for everyday applications, opening up new opportunities for sustainable 3D printing in the future.

Aluminosilicate Clay Minerals
The current focus on renewable energy sources and the circular economy favors the thermal conversion of low-quality fuels, such as biomass and waste. However, the main limitation of their usability in the power sector is the risk of slagging, fouling, ash deposition, and high-temperature corrosion. These problems may be avoided or significantly mitigated by the application of aluminosilicate clay minerals as fuel additives.

Modeling of Two-Phase Volumetric Expanders
Two-phase expansion is the process where a fluid undergoes a pressure drop through or in the liquid–vapor dome. Due to the volume increase in volumetric expanders, a pressure drop occurs in the fluid resulting in flashing phenomena occurring. These phenomena have been studied before in other processes such as two-phase flows or static flash. However, this has not been extensively studied in volumetric expanders and is mostly neglected.

Permeable Pavement Systems for Stormwater Management
There has been growing interest in the field of permeable pavement systems (PPS), especially in the scope of stormwater management as a sustainable urban drainage system (SUDS). Slight modifications within the PPS layers or incorporation of innovative filters could result in improved contaminant removal efficiency. In addition maintenance procedures were proven effective in mitigating clogging effects, mostly occurring at the upper 1.5–2.5 cm of the PPS. Although partial replacement of the PPS mix design with recycled aggregates improved the overall permeability, the compressive strength was slightly compromised.

Exposure Effects Related to Nanomaterial Life Cycles
Nanoparticle-based biosensors are produced and utilized at different scales ranging from laboratory to industrial domains. While incorporating nanomaterials is beneficial to developing high-performance biosensors, at the stages of scale-up and disposal, it may lead to the unmanaged release of toxic nanomaterials. When considering the potential environmental impact and health safety of the scaled-up production of nano biosensors, it is necessary to examine the manufacturing, utilization, and end-of-life disposal of the nanomaterials used.
