Special Issue Information

Dear Colleagues,

In 2020, the global consumption of raw materials reached over 90 billion tonnes, while greenhouse gas (GHG) emissions from the production of materials as a share of global GHGs increased from 15% in 1995 to 23% in 2015. The European building construction sector accounts for 42% of total energy consumption, 38% of total greenhouse gas emissions, 50% of extracted materials and 30% of water consumption. Today, it is clear that we need to transition to a circular economy model to lower the pressure on natural resources and to reduce the overall GHG emissions. This is also a prerequisite to achieve the EU’s 2050 climate neutrality target. To tackle the impacts of construction and other materials-intensive industries on climate change, we need to find alternative sustainable and resource-efficient materials.

In this context, mycelium, the root structure of filamentous fungi, is investigated as a natural self-assembling binder to produce environmentally friendly materials for different industrial applications, mainly construction, furniture, packaging and textile industries. However, challenges arise regarding reproducibility, durability and mechanical strength.

In this Special Issue, we invite experts in the field to contribute to current research trajectories and share their knowledge and findings for further enrichment of the field. We invite biologists, bioengineers, mycologists, material scientists, food scientists, computer scientists, architects and experts from other relevant fields to present their findings on the various applications of engineered mycelium materials.

Limiting the consumption of nonrenewable resources and minimizing waste production and associated gas emissions are the main priority of the construction sector to achieve a sustainable future. This study investigates the sustainability performance of newly developed binders known as alkali-activated binders (AABs). These AABs work satisfactorily in creating and enhancing the concept of greenhouse construction in accordance with sustainability standards. These novel binders are founded on the notion of utilizing ashes from mining and quarrying wastes as raw materials for hazardous and radioactive waste treatment. The life cycle assessment, which depicts material life from the extraction of raw materials through the destruction stage of the structure, is one of the most essential sustainability factors. A recent use for AAB has been created, such as the use of hybrid cement, which is made by combining AAB with ordinary Portland cement (OPC). These binders are a successful answer to a green building alternative if the techniques used to make them do not have an unacceptable negative impact on the environment, human health, or resource depletion. The Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) software was employed for choosing the optimal materials’ alternative depending on the available criteria. The results revealed that AAB concrete provided a more ecologically friendly alternative than OPC concrete, higher strength for comparable water/binder ratio, and better performance in terms of embodied energy, resistance to freeze–thaw cycles, high temperature resistance, and mass loss due to acid attack and abrasion.
