Compost is the outputs of the process, while emission and recyclable materials are the byproducts.
Compost is produced in composting centers, emission is generated from waste degradation process in landfill, and recyclable materials are sorted and sold by scavengers in landfill.
Compost and recyclable material from landfill is the emergy benefit for all scenarios.

Introduction Considerable research work in the field of material science has been progressed towards the development of new light – weight, high performance engineering materials like composites.
Metal matrix composites have become the necessary materials in various engineering applications like aerospace, marine and automobile engineering applications, because of their light-weight, high strength, stiffness and resistance to high temperature [Tomac et al., (1992)].

Seismic Performance of Steel Frames for Sustainable Structural System Oh, Sang Hoon1, a, Ryu, Hong Sik2,b 1 Ph.D, Professor of Dept. of Architectural Engineering, Pusan National University, Korea 2Ph.D, Senior Researcher of Research Institute of Industrial Science & Technology(RIST), Korea aosh@pusan.ac.kr, brhs@rist.re.kr Keywords: Sustainable structure, Full-scale test, Damper, Moment resistance connection, Moment frame.
The survey showed that when compared with existing materials, the environmental load of the steel structure was reduced by approximately 17% in the case of CO2 emissions and approximately 25% in the case of energy consumption.
To contribute to the global environment in the construction sector, particularly in building structures, it is necessary to use those materials and methods that reduce environmental load, i.e. less energy consumption and less waste.
It also requires a design that enhances durability that translates into extending the life of buildings; and the modularization and unitizing design where the materials from the buildings can be removed and recycled and reused, simplifying the entire building design, construction work, and maintenance.
