Sustainable

Various microorganisms as a source of green technology used for bio-inspired wastewater treatment (WWT).
Overuse of water has led to the degradation and scarcity of limited water resources, which prompted the modern world to adopt sustainable measures to save water by increasing its reuse and recycling. The use of microbial-based green technology to treat wastewater has appeared to outweigh conventional wastewater treatment (WWT) technologies because this emerging technology overcomes many of the shortcomings of conventional treatment systems.

After water, concrete is the second most used material in the world. Using life cycle assessments, concrete has typically been found to be 80% of a residential building by weight. Cement production consumes large amounts of energy, motivating a search for sustainable alternatives. Rice husk ash produced in controlled combustion has been found to be a viable replacement for cement. Renewable and sustainable, rice husks have the potential to produce energy while yielding an ash product for use in concrete.
Transportation geotechnics associated with constructing and maintaining properly functioning transportation infrastructure is a very resource intensive activity. Large amounts of materials and natural resources are required, consuming proportionately large amounts of energy and fuel. Thus, the implementation of the principles of sustainability is important to reduce energy consumption, carbon footprint, greenhouse gas emissions, and to increase material reuse/recycling, for example.
