Context

Material flow management began as a largely academic discourse, eventually becoming an actual tool implemented by both countries and industries. The first clear suggestion of material flow management was that of Robert A. Frosch and Nicholas E. Gallopoulos. Published in the '' Scientific American Journal'' in 1989, Frosch and Gallopoulos introduced and recommended the optimization of waste from industrial processes to then be reused for another. While lacking in detail, the analysis of material flow management continued to develop years later, with Robert Socolow and Valerie Thomas beginning to support findings with data, publishing their work in the '' Journal of Industrial Ecology'' in 1997. Material flow management was established as a policy at the 1992 Rio De Janeiro United Nations Conference on Environment and Development (UNCED), or UN "

Uses and applications

One of the terms used in academic and practical discussions of material flow management is "
material flow analysis Material flow analysis (MFA), also referred to as substance flow analysis (SFA), is an analytical method to quantify flows and stocks of materials or substances in a well-defined system. MFA is an important tool to study the bio-physical aspects of ...
" (MFA), which is identified as part of the MFM process. MFA is the more target-oriented analysis of substance flow within a system of production, especially within a company. Material flow analysis is the responsibility of both organized governments and industries. While policies produced by governmental bodies create a framework, the actual design and implementation are done by industries. There are several stakeholders involved in these processes. Material flow management assessment began to take country- and government-focused approaches following a 1997 publication by the World Resources Institute for the Netherlands and Germany. It displayed the total flow, soon adjusted to divide overall flows into its major constituents. In 2002, the
United States Environmental Protection Agency The Environmental Protection Agency (EPA) is an independent agency of the United States government tasked with environmental protection matters. President Richard Nixon proposed the establishment of EPA on July 9, 1970; it began operation on De ...
released the report, ''Beyond RCRA: Waste and Materials Management in the Year 2020'', finding that it is time for society to shift from a waste management-focused environmental plan to a material management-focused plan. Another assessment was conducted by Taylor Searcy in 2017, revitalizing Fiji’s sustainable sea transportation industry to improve socio-economic and environmental impacts. A 2019 study of the material flow in Brazil's mortar and concrete supply chain concluded that in terms of material use efficiency, the ratio of product to material consumption results in a low score, with the most outstanding inefficient processes being quarry waste and building waste at extraction and construction sites.


Government policies

The United States began seriously incorporating material flow management in its environmental policies with the Resource Conservation and Recovery Act of 1976. This gave the government the ability the control hazardous waste produced by all steps of production. Eventually, Congress helped strengthen the RCRA with the Hazardous and Solid Waste Amendments of 1984, incorporating more preventative policies. In 2006, Israel released a Sustainable Solid Waste Management Plan, outlining green goals and priorities for the country's waste system, including economic tools of execution. Policies for household recycling and waste collection separation were then solidified with the 2010 Recycling Action Plan. Korea has also introduced various policies that have executed MFM, specifically in regard to food waste. A 2005 ban on putting untreated food in landfills was followed by a 2012 ban on ocean dumping. In addition to these environmental initiatives, the country combined the economic and social aspects of MFM using food waste agreements with vital economic sectors, as well as public awareness campaigns.

, and echoes the circular economy model, while being represented in media environments as a business model which may help lower the costs of production and waste. An important tool for MFM is the Sankey diagram. It was developed by Irish engineer Riall Sankey to analyze the efficiency of steam engines and has since become a tool in industrial engineering and science. Sankey diagrams are a visual representation of industrial ecology. While they were mostly used in historical contexts, they are useful for assessing ecological impacts.

in biological systems. Focusing on society-wide benefits, it designs a system without waste or pollution and intends to keep products and materials in the system for as long as possible. Applications of the circular economy in the European Union have produced evidence of practicality, estimating that implementation in agricultural, chemical, and construction sectors could reduce up to 7.5 billion tonnes of CO2e globally.


Media representation

In today's studies on the effectiveness of MFM for improving productivity, an analysis of its implementation has been debated with its correlation to government roles in environmental management. With the large spike in environmental disaster concepts regarding the depletion of resources by human activity, MFM could be interpreted as a promoter of the circular economy and an analysis of the necessity of such. In this light, MFM is being utilized as a business strategy that would be meant to optimize vertical integration of manufacturing. Companies focusing on the economics behind MFM, rather than the subject of the environmental crisis, may take note of how MFM lowers the cost of materials by creating an efficient approach to sustainability. Material flow management as a business model may appear to some to promote sustainability in the long run. However, its critics still find these two terms – MFM and sustainability – to be at a crossroads despite the vertical integration model of manufacturing showing agreement in their processes.
