Sustainable materials management
Effectively identifying and analyzing materials are key procedures for breeding novel crop varieties because of the large quantities of materials and their combinations (Han et al, 2018).
Sustainable materials management focuses on the dynamics of materials in economic and environmental activities to optimize material use efficiency and reduce environmental impact. Sustainable materials management (SMM) has been advocated by the Organization for Economic Cooperation and Development (OECD) and US EPA. The objective of SMM is to use materials in which their impacts on the environment are reduced throughout the material’s life cycle. Without compromising social needs, the production and consumption activities in the economic system can be optimized for high resource efficiency.
With a broader perspective, SMM approaches are based on a systematic understanding of the life cycle stages of the relevant materials. To implement SMM, decision makers require comprehensive information on the material flow systems. Therefore, material flow analysis (MFA) is considered an essential methodology for monitoring the resource use and developing environmental policy.
MFA provides a comprehensive perspective on resource use by illustrating the systems affecting complex material flow paths and flow rates through economic activities, providing a fundamental understanding that is critical for setting the priorities for SMM measures (Nakajima et al, 2013; Christis et al, 2015).
Among MFA methodologies, the economy-wide material flow accounts (EW-MFA) and environmentally extended input-output analysis (EEIOA) are the core methods used to measure a nation’s material flows and productivity (Christis et al, 2015).
The EW-MFA method indicates the performance of an economy in terms of its resource consumption, efficiency, and material out-puts using a system of material flow indicators, and waste outputs are also incorporated as material inputs in EW-MFA. EW-MFA analyses are often found in government or academic reports (Raupova et al, 2014; Kovanda; 2013), which are generally read by only a few professional audiences (Chen et al, 2017).
