In the recent decade, using vegetation to cover the building envelope is considered as a sustainable construction practice. Green Wall Systems (GWS) are built with multiple layers which are cladded on the bare wall, using different construction materials and a variety of plants, depending on the geographical locations and climatic conditions. However, the complex cladding devices, built using many processed materials, are reported to have high Embodied Energy (EE) and Embodied Carbon (EC), which questions the sustainability of the GWS. Hence, the research focuses on eliminating the multiple layers by designing a new innovative Integrated Green Wall System (IGWS) to reduce the environmental burden associated with GWS. Further, to improve the sustainability of IGWS, the recycling and reuse potential of millions of cubic yards of sediments, dredged to maintain the economic viability of the great lakes, is investigated by fabricating eco-friendly Dredged Material - Cement Bricks (DMCB). Here, the DMCB is formulated using different experimental mixture designs that vary in the cement content (8%, 10% and 12% by weight) and compacted with different compaction pressures (0Mpa, 2Mpa and 4Mpa). Then, the mechanical properties of the DMCB are investigated by performing a compression strength test, water absorption test and freeze-thaw test as specified by ASTM standards. The promising test results demonstrated that a brick with high performance could be produced using the dredge material. Later, a prototype of IGWS is proposed using DMCB. In addition, life cycle assessment performed to evaluate the environmental impacts of IGWS made of DMCB demonstrated 56% and 72.62% reductions in environmental burden profile in comparison with conventional indirect GWS and modular GWS respectively. Moreover, a reduction in environmental profile of 62.67% and 38.99% was observed, when the bare wall (made of clay bricks) in the tradition indirect and modular GWS was replaced with DMCB.
